Product Description

R404a Rapid Temperature Change Test Chamber R23 Temperature and humidity test chamber


Designed for high and low temperature test and rapid temperature change ESS test for whole product, machine component, and materials.

This machine can test samples of or not of thermal dispersion. For samples of thermal dispersion, the thermal dispersion power should be no more than the refrigerating power of the test chamber. The thermal conditioning process is dynamic, and the refrigerating power varies in different temperature. Therefore if the samples are of easy thermal dispersion, please refer to the load thermal capacity graph blow for a correct test performance.

Cooling Method

Water -Cooled(Cooling system)

Installation Site

  • Work station ground should be flat, good ventilation; no flammable article, corrosive gas or dust
  • No strong electromagnetic radiation source nearby
  • Close to drainage system ( within 2 meters for condensate water)
  • The ground bearing capacity not less than 15000kg/m2
  • Prepare proper power supply and water supply
  • If need water or gas supply, should be equipped with in advance
  • Ambient Temp: 5℃~25℃suggested, 25℃~35℃ function well;(for air-cooled model);5℃~40℃ function well (for water-cooled model)
  • Ambient Humid:≤85%RH
  • Ambient Pressure:86KPa~106KPa
  • Installation space assurances, as following

R404A R23 Temperature And Humidity Test Chamber 1











Cooling Water


Water temperature: 5℃≤ water temp.s ≤28℃.If the source of water is air conditioning chilled water, it’s temp is lower than 10℃ ,need to take some measures preventing pipe condensing water.

1.If adopt the design of the wind cooling, do not need water cooling


2.If user need build new cooling water circulation system.Cooling tower standard≥10tons, or Water chiller refrigerating capacity≥35KW(20℃)


3.Cooling water system :GB50050-1995

Water flow:≥ 10tons/hour

Pipe diameter:G2.5 inch ×2

Inlet water pressure:0.3MPa~0.6MPa

water pressure difference inlet and outlet:≥0.2MPa

Water request:meet standard GB50050-1995







Temp Test



1.Test with no load, meeting GB/T5170-2008, if no other special notice.


2.Ambient Temp 25℃, good ventilation condition: function well if 35℃≥RT>25℃;Cool down rate and thermal load capacity will be affected by ambient low temperature.

Temp Fluctuation:±0.1℃~±0.5℃

Temperature Uniformity:±0.5℃~±1.0℃(empty)

Temp Deviation :±0.1℃~±0.5℃

Temp Gradient:<2.0℃

Linear temperature change rate -

-40℃~+125℃,11℃/min,with load of 5kg of PCBs

Nonlinear temperature change rate:15℃/min


Test Standards
