XD-D02Lab High and Low Thermal Shock Testing Chamber
The machine is used to test the bearing extent of the material structures and composite material in an instant and continuous high temperature and extremely low temperature environment, which is in the shortest time to test its thermal expansion and contraction caused by chemical change or physical harm.
The equipment is widely used in metal, plastic, rubber, electronics and other materials and it can be used as an important reference for improving product quality. It meets the standard of MTL,
Product use:
The machine is used to test the bearing extent of the material structures and composite material in an instant and continuous high temperature and extremely low temperature environment, which is in the shortest time to test its thermal expansion and contraction caused by chemical change or physical harm.
The equipment is widely used in metal, plastic, rubber, electronics and other materials and it can be used as an important reference for improving product quality. It meets the standard of MTL, IEC, JIS, GJB…
Features:
(1). With disk USB recording function, no recorder is required;
(2). Refrigerant servo valve flow calculation control. Power saving 30%;
(3). High temperature and high humidity test to prevent condensation, dripping water technology industry first
(4) In the low temperature working state, the heater does not participate in the work, and the refrigerant flow and flow direction of the refrigeration unit are controlled and adjusted by PWM technology, and the three-way flow of the refrigeration pipeline, cold bypass pipeline and hot bypass pipeline is adjusted to realize the temperature control of the working chamber. automatic constant. In this way, under low temperature conditions,
A 40% reduction in energy consumption can be achieved.
(5) Temperature synchronous rise and fall slope control (IEC68-2-56, 68-2-30), no dripping, no condensation and condensation.
(6) Refrigeration advantages: traditional equipment low temperature control method: Ø Refrigeration compressor start and stop control temperature (temperature fluctuation is large, which seriously affects compressor life,
Obsolete technology) Ø Constant operation of refrigeration compressor + heating PID control (causing cooling capacity and heating to offset to achieve temperature dynamic balance
Waste a lot of electric energy) • New PWM cold control technology realizes low temperature energy-saving operation: The new PWM cold control technology realizes
