About The Walk-in RWI Series
REXGEAR extensive experience in customizing design walk-in environmental chambers based on UUT size, weight, material, temperature and humidity range, temperature rising/cooling time and space limitation.
RWI series is designed for modular assembly and disassembly that can be easily installation on site. It is suitable for batches of samples (UUT) or large-scale UUT to simulate the impact of different climatic conditions for testing the performance and endurance of the product
Models
Applications
The industries served include Automotive, Electronics, Medical, Defense,
Telecommunications, Solar Energy, Aerospace, Pharmaceutical, and EV/EVSE.
Testing Standards
Energy Saving Cooling System
Energy Saving
Traditional Cooling Refrigeration compressor start and stop control temperature which may cause temperature fluctuations, reducing compressor life. Also, continuous refrigeration compressor operation and heating output balance control (cooling capacity and heating phase offset to achieve temperature dynamic balance) which may waste a lot of energy and electricity bill.
Temperature Control and Operation
RWI series walk-in chamber operates the heating and cooling system according to the temperature demand inside the box, PID control the solenoid valve switch between output cooling capacity and heating beeper (cooling without heating or heating without cooling) In the low temperature working state, the heater does not participate in the work, and the refrigerant supply amount is adjusted by PID control. The three-way flow regulation of the refrigeration pipeline, the cold bypass pipeline, and the hot bypass pipeline are used for controlling the temperature of the working chamber in constant temperature.
