Description:

Environmental High and Low Temperature Thermal Shock Test Chamber adpots low temperature and high temperature accumulation slot,after open damper, it will take hot and cold temperature in stored groove import test slots so as to achieve rapid temperature concussion effect,with  balance temperature control system (BTC) , special design of air circulation system, the way to control SSR in P.I.D.make the system add heat is equal to the quantity of heat loss.

Air Conditioning System
1, the air control: forced ventilation circulation, balance thermostat method (BTC). This method not only refers to the case of the cooling system for continuous operation, the control system according to the temperature set point of the heater to control the output of the results by automatically calculating PID output, and ultimately achieve a dynamic equilibrium.
 

2, air circulating means: built between the air circulation fan duct and the long axis of stainless steel, the use of energy efficient refrigerators and regulation system, by effective and efficient heat exchange ventilator, to achieve the purpose of the temperature change. By adjustable air outlet adjusting bolt, thereby significantly improving the chamber temperature uniformity;

3, the air cooling method: multi-stage diaphragm air heat exchanger.

4, air heating: Watkins quality nickel chrome electric heater.

Specifications:

Notes

1. If the high-temp exposure range lower limit + 60°C is required or the low temp exposure range lower limit -60°C, please select the “ambient-temperature exposure” option

2. If the temp fluctuation need to below ±1.8°C please select the “Low temp fluctuation package”

3. Temperature heat-up/pull down time are applicable only during independent chamber operation

4. If the automatically operated sliding door required, please select the “Automatically door package”

5. Air-cooled condenser / Water-cooled condenser both available

6. Apply on water-cooled condenser only

Safety Devices :

Control 

Operation and settings simplified by the use of a touch-screen LCD display (instructions displayed on-screen). At-aglance confirmation of test patterns, test area temperatures, temperature cycles, and trend graph displays.

Daily Maintenance
1. Thermal Shock me a long shutdown is not used regularly every half power, power time is not less than one hour, and related spare parts and testing equipment is functioning properly.

2. Hot and cold shock box should be cleaned regularly evaporator: cleanliness levels because the test is different, in the forced air circulation effect, will gather a lot of dust particles and other small objects on the evaporator should be cleaned regularly.

3. The low-temperature chamber circulation fan, condenser fan and clean balance correction: cleaning and evaporator is similar because of different working environment chamber, circulating fan, will gather a lot of dust on the condenser fans, and other small particles objects should regular cleaning.

4. To move the device thermal shock me at Paddy ASHDOWN Lai instrumentation best technical staff guidance, to avoid damage to the equipment, such as customer self relocation, must have a professional electrician before turning on power to confirm correct operation of the circuit, or will burned equipment related components.
