Two Zone Thermal Shock Test Chamber

Two Zone Thermal Shock Test Chamber



External test chamber is made of dual electrostatic SUS #304 with high temperature resistance as well as galvanized plate as well as internal test chamber is also made of SUS#304 stainless steel plate;

Test Chamber door is designed as single open door and the cable port with different size such as φ50mm、φ80mm、φ100mm for cable through-hole with silicon plug and stainless steel cover; 

The test specimen is design as a mobile basket type to move up and down and with features such as replace shift time less than 10s,and maximum basket loading capacity as 20kg, automatic locking function on test specimen loaded inside of basket as well as automatic shutdown of basket if test chamber door opened; 

Door Frame & Insulation Door Employs high reliable silicon sealing ring & strips, ensure a close test environment thus to provide an excellent test condition for entire test procedure; 

The Heating system is introduced with electrical Heating Tube with fin-shape nichorome heating tube with over-temperature protection functions; the control output signal through SSR relay to control heater current to achieve high-accuracy temperature control;

Air Supply System is designed with an method of air blow from chamber right side to left side and air cycling driven by cycling motor to guarantee proper temperature and humidity uniformity;  multiple-blade centrifugal cycling blower is introduced with high-low temperature resistance blades;

Essential mechanism and subsystems for test chamber such as French Tecumseh /German Bitzer/Copeland Compressor, environmental friendly refrigerant HFC R404A,R23A;

Control System is introduced with control method of Taiwan TATO TT-5166 TH-7 Industrial microcomputer control system with anti-windup PID, BTC controlling unit as well as available software for customization; integrated with sampling module of 24 bit AD converting module to achieve automatic calibration and high accurate control.

Protective System is designed as below to ensure entire test chamber in safe operation condition; 

Over-temperature for test specimen protection function with independent regulation of temperature protector; introduced with non-fuse protective switch; over-temperature for heater protective switch; over-load for compressor protective function, high/low pressure for compressor protection function; over-current protection system.
