How to choose the right dehumidifier?

In terms of air, humidity has special requirements in many scenarios. Except manufacturing industries such as pharmaceutical factories, there are also many situations in daily life that require humidity control, such as archives, underground garages, warehouses, etc.

This article will introduce two common types of dehumidifiers and their characteristics. Hope this can help you decide how to choose the right dehumidifier. 

Refrigeration Dehumidifier

When refrigeration dehumidifier is working, the humid air whose temperature is similar to room-temperature was drawn into the machine through fan, and vapor in humid air is liquefied into water and then discharged through the evaporator and cooling copper tubes. Dry air is heated up by the condenser and discharged through the air outlet. Heat preservation and dehumidification are achieved by this process.

Refrigeration dehumidifiers are widely used for their simple operation and good performance. But its performance will deteriorate as the working environment temperature drops. When temperature is lower than 18°C, frost will form on the equipment surface and the dehumidifier will lose its dehumidification capacity.

Refrigeration dehumidifiers are generally suitable for scenes where the ambient temperature is between 18-40°C, such as libraries, archives, and places where food and agricultural seeds are stored.

Desiccant Rotor Dehumidifier

The principle of the rotary dehumidifier is that when humid air passes through process area on rotor, the moisture is adsorbed by adsorption medium and then dried air is sent out; the rotor which adsorbed the moisture moves to the regeneration area, where the regeneration air sent from the reverse direction will take out the moisture and the adsorbent will be dried. After that, desiccant rotor will continue the next recycle of air processing.

The rotary dehumidifier consumes more power than a refrigeration dehumidifier, and it will also increase the room temperature during operation.

Compared with refrigeration dehumidifiers, the performance of rotary dehumidifiers is more stable. Rotor dehumidifier adopts active silica gel and molecular sieve as a non-toxic and tasteless green adsorption medium. It is safe, environmentally friendly, clean, free of floating dust and non-corrosive, and can also be sterilized. It is especially suitable for lithium batteries, pharmaceuticals, food and biochemical industries.

Puresci's desiccant rotors can firmly and evenly combine the adsorption material and the substrate through chemical reaction, maximizing the product's dehumidification performance and capacity. Moreover, Puresci has a patented desiccant rotor, the PST desiccant rotor that saves 25% more energy than a regular desiccant rotor.
