Through three interrelated systems: refrigerant cycle system, air circulation system, electrical automatic control system.

1, temperature and humidity chamber refrigerant cycle system: heat the evaporator liquid refrigerant absorbs the air (air is cooled and dehumidified) and begins to evaporate, forming a certain temperature difference, the liquid refrigerant between the refrigerant and air also completely evaporated into gas, after the compressor suction and compression (increased pressure and temperature), the gaseous refrigerant passes through the condenser (air / water) to absorb heat, it condenses into a liquid. Through the expansion valve (or capillary) throttled into low temperature low pressure refrigerant into the evaporator, the refrigerant to complete the cycle.


2, The air temperature and humidity chamber ring system: Fan is responsible for the return air from the air sucked The air through the evaporator (cooling, dehumidification), humidifiers, heaters (heating) after delivery outlet to the space required for the user air mixing air and space sent back after the return air.

3. Performance of Environmental Temperature Humidity Laboratory Test Chamber:



System & Performance Options

  • Low and Ultra-Low Humidity Extends the humidity control range. (Normal Humidity Range Diagramed) 
  • Water-cooling system.
  • Dry Air Purge keeps moisture in the chamber extremely low by purging with -40 °C. Compressed air supply required
  • Additional shelves, 50 Kg  loading
  • Cable ports with flexible silicone plug, 50 , 100, 150mm or customer specific diameters

Frozen System

Modular cooling system, high efficiency, easy installation and maintenance;
Waterway switchboard separation, reduce security risks;
Flooding leak, leak completely eliminate the potential leak;
DuPont uses environmentally friendly refrigerant, non-polluting;
Cooling system, electric control system number of security mechanisms


Control Method

Balance thermostat humidity control system (BTHC), to P.I.D. controlled SSR, the heated humidification system equal to the amount of heat and moisture loss, so long-term stability in use.



Energy-saving Design

In addition to fully consider the safety of refrigeration units, efficient use of all sectors, but while taking multiple energy saving measures: such as: adjusting the cooling capacity of the refrigeration system, liquid-gas bypass regulation, evaporation temperature regulation, low temperature at any point when the thermostat without heat balance, operating power can be reduced to half, so that operating costs and failure rates of the refrigeration system down to a more state of the economy.
Intelligent automatic transfer system expansion, the load automatically adjust the refrigerant flow + intelligent electric power data value (%) to match heating and cooling (load) Analog output data automatically according to the output value. This design than the traditional design saving more than 30%.


(Advanced refrigeration design is especially compact for HD-Series Chambers)
