Question 1

Size a floor standing dehumidifier on real removal capacity, not the nameplate figure. Work out the moisture load from room volume, the humidity change you need and the infiltration from doors and people, then divide by 0.6-0.7 to convert that real requirement into the nameplate capacity you should buy.

For every metre above that, add roughly 25–35% to the volume-based figure. A 500 m² hall with a 6 m ceiling should be sized closer to 900 m² of nominal area.Three adjustments people forget1Low target humidityThe lower the setpoint, the harder the machine works. Below 45% RH, check the performance curve — capacity can fall well below the rating.2Door traffic and infiltrationMore than 20 door openings a day means adding 30–50%. Airlocks, strip curtains or air curtains reduce this load at source.3Wet processes and occupancyOpen water, wet floors, plant transpiration and people all add load. Each occupant contributes roughly 50–80 g/h of moisture.Why oversizing is also a mistakeA unit that is far too large hits its setpoint quickly and short-cycles. That raises peak electrical demand, wears the compressor faster, and leaves humidity unevenly distributed because the fan never runs long enough to mix the room air.The practical target is a machine that runs long, steady cycles at the design condition, with enough reserve to recover after door openings. Where the load varies a lot through the day, two smaller units on independent humidistats will track the load far better than one large one.Right-sized units run longer cycles, which improves both air mixing and equipment life.In wide halls, several mid-size units placed diagonally outperform one large machine.Representative project configurationCold-store antechamber400 m² · 7 m ceilingHeavy trafficThe space between a frozen store and the loading dock suffered constant floor icing.

Question 2

A floor stand dehumidifier is a self-contained, ground-mounted unit that you position wherever the moisture problem is. It is best used in warehouses, basements, logistics halls, food and textile stores, indoor pools and production areas - anywhere the space runs at normal ambient temperature, the target is 45-60% RH, and you want capacity you can move or add without building work.

Direct answerA floor stand dehumidifier is a self-contained, ground-mounted unit that you position wherever the moisture problem is. It is best used in warehouses, basements, logistics halls, food and textile stores, indoor pools and production areas — anywhere the space runs at normal ambient temperature, the target is 45–60% RH, and you want capacity you can move or add without building work.20–1000 L/dayTypical capacity range45–60% RHWhere it performs bestNo ductingInstalled in minutes8–12 mEffective coverage radius per unitWhere a floor standing unit is the right answerA floor standing unit needs no ductwork, no ceiling void and no structural work to start drying a space.Warehouses and logisticsProtects cartons, pallets, textiles and metal goods from mould, rust and moisture regain. Multiple units give flexible coverage across racked aisles.Basements and underground storesSolves persistent damp where ventilation alone cannot, and where no ceiling void exists for a ducted unit.Food and beverage areasControls condensation on cold surfaces, keeps packaging dry and reduces slip hazards on floors.Production hallsSteadies humidity around hygroscopic processes such as paper, wood, adhesives and coatings.Indoor pools and leisureHandles continuous evaporation while limiting structural condensation and corrosion.Construction dry-outSpeeds screed, plaster and paint drying before handover, then moves to the next site.Floor stand versus the other mounting optionsFactorFloor standCeiling mountedHand pushFloor space usedYes, about 0.5–1 m²NoneYes, but movableInstallationPlace and connect powerStructural fixing, drainageWheel in and plug inAir distributionLocal, needs spacingWhole-room, more uniformTargeted, temporaryBest forLarge open areas, phased budgetsTight floor space, cleanroomsMulti-site, temporary workCapacity ceilingUp to 1000+ L/dayMedium rangeLow to medium rangeFloor space is the trade-off. If every square metre of floor is revenue-producing — a clean production line, a packed cold store — a ceiling mounted dehumidifier is usually worth the extra installation cost. If the floor is racking and aisles, floor standing units in unused corners cost less and are easier to service.Practical installation notesLeave 50 cm of clearance on the intake side and at least 30 cm behind the unit. Do not place a unit directly against a wall or inside a tight rack pocket — restricted airflow is the most common cause of disappointing performance.Drainage comes first in the planning. A gravity hose needs a continuous fall to a floor drain; where that is impossible, choose a pump-equipped model and check the lift height. Filter cleaning every two to four weeks keeps capacity stable in dusty environments.Floor standing units are typically placed along walls or in unused corners, spaced to cover the full floor plate.East Dehumidifier floor standing units are tested for electrical safety, control logic and capacity before dispatch.Representative project configurationTextile raw-material store800 m²Target 55% RHA yarn store was seeing fibre regain variation between seasons, which showed up as inconsistent fabric weight downstream.

Question 3

For a 500 m² warehouse with a 4 m ceiling held at 27 °C / 60% RH, budget roughly 200-270 litres per day of real removal capacity. Because nameplate capacity is measured at 30 °C / 80% RH, that means buying nameplate capacity in the 350-450 L/day band - typically two 240 L/day units rather than one large machine.

A 240 L/day unit covers an effective radius of about 8–12 m, so place the two units diagonally rather than side by side.For drainage, a gravity line with a continuous fall is the most reliable option. Where no floor drain exists, specify a built-in condensate pump; check lift height against the discharge point before ordering.Diagonal placement of two mid-capacity units outperforms a single large machine in wide, racked spaces.Allow 50 cm clearance around each unit and keep carton stacks at least 30 cm apart for air circulation.Representative project configuration500 m² electronics storeTarget 50% RHBasement levelAn underground component store with no external wall drainage and a high water table.

Question 4

Choose a condensing dehumidifier if your warehouse stays above about 15 °C and you only need to hold 45-60% RH - it costs less to buy and roughly half as much to run. Choose a desiccant rotor dehumidifier if you need below 40% RH, if the space runs below 10 °C, or if your spec is written as a dew point rather than a relative-humidity figure.

If room temperature swings across the day, the same absolute moisture content shows a very different RH reading. Where temperature is unstable, specify by dew point — it is the more robust control variable.What each technology actually costs to runCondensing machines move heat with a compressor, which is inherently efficient: published industry figures put them at roughly 1.6–2.6 litres of water removed per kilowatt-hour at 30 °C / 80% RH.Desiccant rotors must heat a regeneration air stream, typically to 120–150 °C, to drive the captured moisture back out of the wheel. That thermal penalty is why they land near 0.6–1.0 L/kWh — often around half the water per unit of energy.In warm, humid conditions that gap makes condensing the clear winner. But the comparison flips when the target is deep dryness or low temperature, where a condensing machine simply cannot reach the setpoint at any energy cost.Condensing units from East Dehumidifier cover 20 to more than 1000 L/day for ambient-temperature spaces.Desiccant rotor units take over below 40% RH, in cold rooms, and wherever a dew point is the controlling spec.Representative project configurationTwo warehouses, one siteDifferent specsA distribution site operated two halls side by side.

Question 5

A condensing dehumidifier removes moisture by pulling room air over a refrigerated coil, cooling it below its dew point so water vapour condenses into liquid, and draining that water away. The dried air is then warmed a few degrees before it returns to the room. It is the most energy-efficient dehumidification technology whenever the space stays above roughly 15 °C and the target humidity is above about 45% RH.

Direct answerA condensing dehumidifier removes moisture by pulling room air over a refrigerated coil, cooling it below its dew point so water vapour condenses into liquid, and draining that water away. The dried air is then warmed a few degrees before it returns to the room. It is the most energy-efficient dehumidification technology whenever the space stays above roughly 15 °C and the target humidity is above about 45% RH.15–35 °CEffective operating range45–60% RHTypical control band1.6–2.6 L/kWhWater removed per kWh at 30 °C / 80% RH20–1000+ L/dayEast Dehumidifier capacity rangeHow the condensing cycle works, step by step1Air intakeA fan draws humid room air through a washable filter into the unit.2Cooling below dew pointThe air passes the evaporator coil, which is colder than the air's dew point, so vapour turns into liquid water.3Condensate removalWater drips into a tray and leaves through a gravity hose or a built-in condensate pump.4Reheat and dischargeThe same air crosses the condenser, gains 3–5 °C, and returns to the room drier and slightly warmer.Why it works this wayWarm air holds far more water vapour than cold air. A condensing unit exploits that physical rule: instead of adding a drying agent, it chills the air until the vapour has nowhere to go and falls out as liquid. Because the refrigerant loop recovers the condenser's heat to re-warm the outlet air, the process costs far less energy than boiling water off a desiccant wheel.The compressor, evaporator, condenser, expansion device, fan and humidistat are the six parts that do all the work. There is no consumable desiccant, no regeneration heater, and no chemical by-product — which is why maintenance stays simple and the running cost stays low.The one hard limit: temperatureOnce room temperature approaches the coil temperature, condensate starts freezing on the fins instead of draining. Below roughly 15 °C the unit must pause for defrost cycles, capacity drops sharply, and below about 5 °C a condensing machine is the wrong tool. That is the crossover point where East Dehumidifier specifies a desiccant rotor dehumidifier instead.Condensing dehumidification is the standard choice for warehouses, logistics centres and storage halls that run at normal ambient temperature.Every East Dehumidifier condensing unit is run-tested for capacity, leakage and electrical safety before shipment.Capacity changes with room conditionsCapacity always follows room conditions, so East Dehumidifier sizes from the actual operating point rather than the catalogue figure.Room conditionUsable capacity vs. nameplateWhat it means in practice30 °C / 80% RH (standard test point)100%Nameplate litres per day are quoted here27 °C / 60% RH (typical warehouse)60–70%Size with this de-rating, not the nameplate figure20 °C / 60% RH (cool season)40–50%Expect noticeably slower pull-down10 °C or belowBelow 30%, icing riskSwitch to desiccant rotor technologySizing rule of thumb: for a closed warehouse with 4–6 m ceilings and normal door traffic, budget roughly 1 litre per day of capacity per 1.5–2 m² of floor area.

Accepted Answer

Yes, most our buyer use ceiling mounted dehumidifiers for cannabis grow. And the feedback is excellent.

Question 10

dehumidifier can lower humidity to accelerate the water evaporation and move to transport the nutrients.

Accepted Answer

Humidity VS Plant Grow Plants need nutrients for growing up. And water carries nutrients to each parts of plant by water transportation. At the same time, the water evaporation helps water transportation inside plant. And the high humidity in the air will decrease water evaporation. In other words, the air humidity will absolutely affect the  transportation of nutrients. Therefore, such as raining, existing water, soil water level and evaporation conditions are the factors will affect the water vapor supply.  The absolute humidity during the year is higher in the rainy season than in the dry season. The change in the absolute humidity during the day is largest in coastal areas and autumn and winter, and the smallest in early morning. In other areas, the two highs appear between 9 and 10 hours and around the day, and the two lows appear before sunrise and afternoon.  The relative humidity is determined by absolute humidity on the one hand, and by air temperature on the other hand. In cold areas and seasons, the air humidity can easily reach saturation, and the relative humidity may be high when when the absolute moisture or water vapor pressure is not too high. The relative humidity is often low in warm areas and seasons under the same absolute humidity conditions.  In this case we need to artificially control the relative humidity to achieve stronger transpiration and plant  thrive.  EAST PLANT GROW DEHUMIDIFIER is a good choice for control the plant humidity. To save each cost you have paid, EAST DEHUMIDIFIER you can well control your plant humidity environment.

Question 11

humididity control with dehumidifiers | the environment of using dehumidifiers.

Accepted Answer

Nowadays, more and more people are paying attention to the environment, not only the air purity, but also the air moisture. Nearly all the goods need to be kept in certain environment for long time storage. In this case the suitable humidity and temperature will be the essential element of keeping goods in warehouse. You may remember the water cycle from our text book: evaporation, condensation, and precipitation. What you might not realize is that the water cycle is always taking place in the air you’re breathing, even when you’re spending time inside.“Humidity” is a measure of water vapor in the air. Dehumidifiers remove or minimize this water vapor.If people have asthma or allergies, a dehumidifier might help take moisture from air to relieve symptoms and make breathing easier. The mold, dust mites, pollen, animal dander are concluded as normal allergy triggers. Keeping the air dry will minimize the triggers of allergy. In this case a dehumidifier does indeed play an important role in improving your indoor air quality. Whatever plants you have kept at home or how many air purifier have been installed. It is impossible to keep air quality at home healthy if there is too much moisture.  You may need to buy a dehumidifier if you have below signs. *People have a prolonged allergy season. *There is a persistent damp sell in the room *where you live or you keep goods. *Your room experiences water leakage or flooded. *When you feel the muggy air indicates the water vapor in the air meet the level that you can see. *If you or your friends has allergy to dust mites. *Clothes, furniture, or home appliance smells damp or moldy even they have been washed or cleaned. *Goods become mouldy or food gone off quickly. *You have important electrical appliance that very sensitive to environmental humidity. *You have sensitive plant need to be cultivated at certain humidity for thriving

Accepted Answer

The drainage system of EAST dehumidifiers There are different drainage systems for EAST dehumidifiers. Such as natural drainage system, water tank, water pump and external auto stop float system. In order to achieve the best performance, EAST can also custom make different drainage system as buyer request. Direct natural drainage system of overhead dehumidifier. Optional water tank or direct drainage system of portable dehumidifier.

Question 15

Self-defrost dehumidifiers | dehumidifier defrost | EAST dehumidifier will self-defrost automatically

Accepted Answer

Self-defrost mode Due to the low temperature on evaporator, the moisture need to condense on it. It is likely that the evaporator will frost after long time working in the room with lower temperature.In this case the EAST dehumidifier will stop working automatically and switch into self-defrost mode. The corresponding symbol will be shown on the controller and machine will not dehumidify till the self-defrost mode finish. Do not worry about the machine, just wait and it will back to work after self-defrost mode finish.

Question 16

frosted dehumidifier | dehumidifier frost| evaport frost

Accepted Answer

Dehumidifier will frost if working in the working temperature is lower than 18℃ The working temperature of dehumidifier is 5~38℃. And it will frost if the room temperature is lower than 18℃. The principle of dehumidifier is similar as air conditioner, with the auto-defrost system, it can work in condition higher than 5℃. The dehumidification will rely on room temperature. Normally when evaporator temperature will easily meet 0℃ or even lower if room temperature is lower than 18℃. In this condition the water on evaporator will frost.But do not worry,there is auto-defrost system on EAST dehumidifier. It will switch into defrost mode and start to dehumidify once the defrost mode finish.

Question 17

24 hours non-stopping dehumidifiers | dehumidifier works non-stopping

Accepted Answer

Timing and 24 hours non-stopping dehumidifiers. Thanks to the complete control system of EAST dehumidifiers. It is no problem to keep dehumidifiers 24 hours working or timing. You can set the desired humidity on controlling panel and keep dehumidifiers with 24 hours on. It will stop work automatically once room humidity meet the desired setting. And start to work once room humidity becomes higher.  And you can also set on or off time on controller panel. The dehumidifier will work or stop by your desired time.

Question 18

compressor protection | dehumidifier protection | secondary start delay protection

Accepted Answer

Complete protection for EAST DEHUMIDIFIERS Complete circuit protections are essential parts of EAST dehumidifiers. The secondary start delay is the basic compressor protection. In case of unstable power supply or frequent on-off operation. The compressor will not immediately start until 3~5 minutes later so that the refrigerant inside and compressor can be in good condition. Besides that, fan off delay protection and low refrigerant pressure indication on screen are also available for EAST dehumidifiers. Fan will continue work for 3~5 minute to release hot air  after compressor off. And in case of terrible conditions, such as high temperature or fan blocks, there will be high pressure inside the refrigerant circulation. The protection mechanism will be also triggered to protect compressor.

Question 19

air break for dehumidifiers | dehumidifier air break | OEM dehumidifier

Accepted Answer

Air Circuit Breakers for dehumidifiers An air Circuit Breaker (ACB) is an electrical device used to provide Over current and short-circuit protection for electric circuits over 800 Amps to 10K Amps. They are widely used for the protection of industrial plants and electrical machines such as air conditioner,  capacitors, generators, and transformers, etc. They are also used at home when total current over 5 amps. You so if you are using dehumidifiers bigger than 90L/D(@RH80%, 30℃）, its better to install an air circuit breaker separately for the dehumidifier. Because the starting current of compressor normally 3~5 times than working current.  So it is requested to choose ACB at least 3 times of the dehumidifier working current if your dehumidifier is bigger than 90L/D(@RH80%, 30℃）.

Question 20

The importance of stable voltage to dehumidifiers. | instable voltage will harmful to dehumidifiers

Accepted Answer

Voltage instability will be harmful to dehumidifiers Using stale power supply for all electrical appliance is a must. Although EAST can offer appliance with different voltage & frequency.
