High temperature/humidity test chamber

High temperature and humidity test chamber is ideal to high and low temperature, high/low temperature cycle test of products (whole machine), parts and materials, as well as constant or alternating humidity and heat test. The test chamber can be used for heat and non-heat dissipation to test samples. For the heat dissipation test sample, its heat dissipation power cannot exceed the refrigeration capacity of the test chamber, because the refrigeration capacity is dynamic, it varies with the change of temperature point. At the same time, the higher humidity will be affected by condensation when the heat of the heat dissipation product needs to be cooled and balanced.

Technological Innovation: 

New PWM cold control technology enables low temperature energy saving operation. In the low temperature working state, the heater does not participate in the work. The PWM technology will control the refrigerant flow and flow direction of the refrigeration unit, and the three-way flow regulation of the refrigeration pipeline, the cold bypass pipeline, and the hot bypass pipeline is to realize the temperature of the working chamber automatically constant. This method can reduce energy consumption by 40% under low temperature conditions.

The technology is based on Sporlan's customized PWM control valve：

This technology regulates the flow of pipelines through frequent action of solenoid valves. Standard solenoid valves cannot adapt to the situation and metal fatigue damage will occur in a very short time. At present, only XM series products produced by Sporlan Company in the United States (this product cannot be imported from normal channels) can support this technology. The following figure shows the difference between solenoid valves.
