High and low temperature damp heat test chamber

High and low temperature damp heat test chamberProduct Features
1. The refrigeration unit adopts the original French "Taikang" fully enclosed compressor.
2. The refrigeration system adopts a unit or binary low-temperature circuit system design.
3. Adopting a multi wing air supply fan for strong air circulation, avoiding any dead corners, can make the temperature distribution in the testing area uniform.
4. The design of air circulation for air outlet and return ensures that the wind pressure and speed meet the testing standards, and can quickly stabilize the temperature at the moment of opening the door.
5. Heating, cooling, and system independence can improve efficiency, reduce testing costs, increase lifespan, and decrease failure rates.
6. The temperature control adopts a fully imported touch button instrument, with simple operation and setting.
After inputting the data and experimental conditions, the controller has a locking function to prevent human touch from changing the temperature value.
8. It has the function of P.I.D automatic calculation, which can immediately correct temperature change conditions, making temperature control more accurate and stable.
9. Optional printer.

High and low temperature damp heat test chamberAir conditioning system:
1. Air conditioning method: Forced ventilation internal circulation balance temperature control (BTC), which refers to the control system automatically calculating the output of the heater based on the set temperature point through PID calculation under continuous operation of the heating system, ultimately achieving a dynamic balance.
2. Heating method: Nickel chromium alloy electric wire heating, PID regulation, actuator: solid-state relay
3. Air circulation device: centrifugal fan, long axis external motor drive.

Control system::
1. The temperature measuring element adopts a high-precision PT100 temperature sensor for temperature measurement.
2. Heating system composition: SSR solid-state relay drive.
3. Controller: Equipped with an imported TEMI990 programmable LCD touch screen, the temperature and humidity controller comes with a USB interface and can be remotely monitored through networking. It can display set parameters, time, heater/humidifier working status, etc., and also has PID control
4. Parameter self-tuning function. The control system uses an intelligent control software system with automatic combination of heating, humidification and other subsystems to ensure high-precision control throughout the entire temperature and humidity range, achieving the goal of energy conservation and consumption reduction. A complete detection device can automatically display detailed faults and alarms, such as the controller automatically displaying the fault status when an abnormality occurs in the test chamber.
