Application Features

① Initial filter section: plate G4 or bag filter is used

② Front surface cooling/front preheating section: the cold medium of the front surface cooling can be frozen water or direct evaporation. Conventional pre-cooling design dew point range is 10℃-18℃; Under special working conditions, the front cold dew point can be designed to be about 7℃ ~ 10℃; Pre-heating can be performed with hot water, steam or electric heaters.

③ Regenerative fan section: direct centrifugal fan

④ Runner dehumidification section (first stage) : adsorption silica gel runner and runner frame; Runner drive device; Runner seal system; Runner detection device

⑤ Mixed air section: generally the mixture of dry air and return air

⑥ Regeneration connection section: the front regeneration and the rear regeneration are connected with the insulation air duct

⑦ Regenerative heating section: regenerative heater (electricity/steam/natural gas/energy storage heat recovery)

⑧ Processing fan section: belt driven centrifugal fan/no volute fan

⑨ Filter section: adopts bag type F6/F8 or box type high-efficiency H13 filter

⑩ Mixed air table cold section: after the table cold coil is generally dry cold coil, using frozen water or direct evaporation can be

⑪ Runner dehumidification section (second stage) : adsorbed silica gel + molecular sieve compound runner and runner frame; Runner drive device; Runner seal system; Runner detection device

⑫ Steel structure foundation: high strength, easy to transport, lift, move and place

⑬Post-surface cooling/post-heating section: the post-surface cold coil is generally a dry cold coil, using chilled water or direct evaporation type; The rear heater can be in the form of hot water, steam or electric heating




Technical Features

1、modular design, according to the different needs of customers, choose different modules to achieve the precise control of temperature, humidity, cleanliness;

2、the complete unit includes adsorption runner, air supply main fan, air purification filter, regenerative heater with temperature regulation, regenerative exhaust fan, precise temperature control of refrigeration/heating part, kill and humidification and other functional segments, intelligent control of the electrical system;

7、the main components of Polder equipment can be removed from the unit for cleaning or maintenance, and the control uses a number of alarm display functions, such as filter blocking alarm, motor overload, current overload, high temperatu.


Scope Of Application

1、the temperature and humidity have strict requirements of the treatment engineering and production process

Such as: automobile, ship spray treatment, lithium batteries, electronic products manufacturing, powder products such as milk powder production and gas transmission process

2、Storage of various items sensitive to temperature and humidity

Such as: museums, archives, wood, grain, military equipment, ammunition, electronic products, food warehouses, seed banks, gene banks and ships

3、Scientific research laboratories, especially those engaged in high-tech biological, aerospace and electronic laboratories

For example, in the experiment, it is often necessary to simulate various environmental conditions, and at this time, the humidity of the air will produce more stringent requirements

4、other easy to produce a lot of moisture in the building

Such as: swimming pool, large fresh supermarket, ice rink and so on
