THREE ZONE THERMAL SHOCK TEST CHAMBER

FUNCTIONAL FEATURES--THREE ZONE THERMAL SHOCK TEST CHAMBER

External Test Chamber is introduced with dual-side electrostatic high temperature plastic spray and galvanized steel plate while
Internal test chamber is introduced with high/low temperature resistant SUS #304 stainless steel plate; 

the support mechanism is designed as square frame structure to enable a stable & reliable test environment; 

Test Chamber door is designed as single open door and the cable port with different size such as 50mm,80mm,100mm for
Cable through-hole with silicon plug and stainless steel cover; 

Door Frame & Insulation Door Employs high reliable silicon sealing ring & strips, ensures 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.
