Working principle of Holtop Fresh Air Dehumidification Systems

The Holtop fresh air purification and dehumidification system adopts the principle of cooling dehumidification. By reducing the temperature of the air, the excess moisture  in the air will be extracted, and then adjust the air to  comfortable temperature and humidity by the reheating system.

Main functions of the HOLTOP dehumidification system:

1. High Efficient Heat Exchange System
Holtop heat exchange system uses a highly efficient hydrophilic aluminum foil honeycomb heat exchanger. Compared to other forms of heat exchangers, Holtop’s heat exchangers increase the vaporization area and contact surfaces higher vaporization efficiency and speed. At the same time, the honeycomb fin structure increases the disturbance to the air, allowing the air and heat exchanger toexchange heat more thoroughly.
2.Imported World Famous Compressor
Holtop uses imported international brand compressors with low noise and high efficiency.
Excellent Cooling Components.
Holtop’s high-efficiency cooling dehumidification system uses international famous brand cooling accessories: including solenoid valves, filters, etc., to ensure the reliability, stability, safety and performance of the dehumidifier.
3.Multiple Filters to Ensure Health
A large-area primary filter can effectively filtrate large particles such as hair and pollens.
HEPA-grade high-efficiency filter can easily purify harmful particles such as PM2.5, and the purification efficiency is over 95%.
The activated carbon and cold catalyst filter can double effectively remove harmful substances fiter such as formaldehyde, benzene and TVOC, as well as odor.
The UV sterlizing function (optional) can quickly kill 99% of bacteria, molds and viral viruses in the air.
4.Make the Moist Air Clean and Dry
HOLTOP fresh air purification and dehumidification system can simultaneously solve the problems of indoor environment, such as lack of oxygen, humidity and various pollutants like PM2.5.
