Mask protective clothing temperature and humidity pretreatment constant temperature and humidity chamber

The constant temperature and humidity test chamber is suitable for testing the performance indicators of aerospace products, information electronic instruments, materials, electrical and electronic products, and various electronic components in high and low temperature or humid and hot environments.

Box Structure

The box body of the high and low temperature damp heat test chamber is processed and formed by CNC machine tools, with a beautiful and elegant appearance, and adopts non reactive handles for easy operation.

The inner liner of the box is made of imported high-grade stainless steel (SUS304) mirror panel, and the outer liner of the box is made of A3 steel plate spray painted, which increases the appearance texture and cleanliness.

The water replenishment tank is located at the bottom right of the control box and has automatic water shortage protection, making it more convenient for operators to replenish water sources.

The large observation window is equipped with lighting to keep the inside of the box bright, and uses tempered glass embedded in the heating body to observe the condition inside the box clearly at any time.

Separating the humidification system pipeline from the control circuit board in the high and low temperature wet heat test chamber can prevent malfunctions caused by water leakage in the humidification pipeline and improve safety.

The waterway system pipeline circuit system adopts a door opening, which is convenient for maintenance and inspection.

A double-layer high-temperature resistant high tensile sealing strip is used between the door and the box to ensure the sealing of the testing area.

The left side of the box is equipped with a test hole with a diameter of 30mm, 50mm, or 100mm, which can be used for external testing power or signal lines. (The aperture or number of holes should be specified when placing the order).

The bottom of the machine adopts high-quality fixed PU movable wheels.

Mask pre-treatment constant temperature and humidity chamber

control system

High and low temperature humidity test chamber imported from Japan with digital touch buttons and PID microcomputer SSR temperature controller.

The external boiler steam humidifier has energy-saving and consumption reducing functions, which can save 70% of energy consumption.

The main components of the electrical control adopt imported "Schneider" to better control temperature.

The insulation system uses ultra-fine glass fiber to fill the insulation area, and non-metallic high and low temperature resistant materials are used at the connection between the inner and outer bile ducts, effectively reducing temperature conduction.

It has the function of automatic calculation, which can immediately correct the temperature and humidity change conditions, making temperature and humidity control more accurate and stable.

refrigeration system

The refrigeration unit adopts the original French "Taikang" fully enclosed compressor.

The refrigeration system adopts a unit or binary low-temperature circuit system design.

American "Aigao" dry filter, Taiwan, China "Guanya" oil separator, Italian "Castrol" solenoid valve.

Adopting a multi wing air supply fan for strong air circulation, avoiding any dead corners, can make the temperature and humidity distribution in the testing area uniform.

The design of air circulation for air outlet and return meets the testing standards for wind pressure and speed, and can quickly stabilize the temperature and humidity at the moment of opening the door.

The independent heating, cooling, and humidification system can improve efficiency, reduce testing costs, extend lifespan, and lower failure rates.
