DHS-800 Box Structure
|
The box body of the constant temperature and humidity test chamber is processed and formed by CNC machine tools, with a beautiful and novel appearance, and adopts a non reactive handle for easy operation;
The inner lining of the box is made of imported high-grade stainless steel (SUS304) mirror panel or 304B argon arc welding, and the outer lining of the box is made of A3 steel plate sprayed with plastic;
Adopting a microcomputer temperature and humidity controller, the temperature and humidity control are precise and reliable;
Large observation window with lighting to keep the box bright, and using double-layer glassglassObserve the condition inside the box clearly at all times;
Equipped with an independent temperature limit alarm system, it automatically interrupts when the temperature limit is exceeded, ensuring the safe operation of the experiment without any accidents;
A test hole with a diameter of 50mm is provided on the left side of the box.

DHS-800 Control System
|
Constant temperature and 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 the well-known imported brand "Schneider", which is betterlandControl 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 ductsmaterialEffectively reduce temperature transmissionGuide;
Equipped with automatic calculation function, it can immediately correct the temperature and humidity change conditions, enabling temperature and humidity controlmanufactureMore precise and stable.

DHS-800 refrigeration system
|
The refrigeration unit of the constant temperature and humidity test chamber adopts the original French "Taikang" fully enclosed compressor;
The refrigeration system adopts a unit or binary low-temperature circuit system design;
American "Aigo" dry filter, Taiwan "Guanya" oil separator, Italy "Castrol"”Solenoid valve;
Adopting a multi wing air supply fan for strong air circulation, avoiding any dead corners, and ensuring even temperature and humidity distribution in the testing area;
The design of air circulation for air outlet and return, with wind pressure and speed meeting the testing standards, can quickly stabilize the temperature and humidity at the moment of opening the door;
Fully independent heating, cooling, and humidification systems can improve efficiency, reduce testing costs, extend lifespan, and decrease failure rates.
