Question 1

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

Question 5

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 6

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 7

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 8

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 9

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 10
