(-70°C to 180°C) Constant Climate Chamber Environmental test chamber

The Dynamic Constant Climate Chamber Environmental test chamber, which can detect the heat-resisting, cold-resistant, drying resistant and wet resistance of the equipment under each environment. It is suitable for detecting the quality of electronic, appliance, communication, instrument, vehicle, plastic product, metal, food, chemicals, building materials, medical treatment, spaceflight product, etc.

This Constant Climate Chamber is an alternative to complex individual solutions for cyclical temperature tests.

Reference Standards

Structural Features

• The inner chamber material is made of SUS#304 stainless steel with 1.2mm thickness. Full welding structure, its sealing is very well and it’s not easy to get cracked.
• The external material is made of cold-rolled plate with 1.5mm thickness, it has gone through brushing, polishing, painting treatment, it's not easy to get scratched.
• The insulation material is made of polyurethane foam with thickness  of 100mm.
• The door seal adopts double silicon rubber sealing material.
• The observation window is 4 layers of tempered glass, the size you can choose by yourself.
• In addition, in order to prevent frosting on the observation window when running low temperature, we setup a heating wires inside to get it di-frosting.
• Left sides of chamber are equipped with a diameter 50mm cable port, the silicon plug is high & low temperature resistance.

Refrigeration System

• Compressors equipped with world famous brand such as Tecumseh (France made), Bitzer or GEA BOCK (Germany made).
• Shock absorption and noise reduction process,slow down the vibration, protect the compressor.The pipe bending technology: The bending process can minimize the connector point and make refrigerant flow more efficiently.
• It applies Denmark DANFOSS and Japanese SAGLNOMIYA solenoid valves to improve the overall reliability of the equipment.
• MP10 module has motor over-heating protection (with LED indicator), exhaust temperature over-heating protection (requires optional temperature monitoring probe and LED indicator), power indicator, alarm function.

Electrical System

• The overall layout of the circuit cabinet looks very neat and professional. Our circuits are arranged in accordance with UK standards and are equipped with complete circuit diagrams. Each line has a unique code which is clearly defined and easy to locate for troubleshooting.
• Use electrical components of world famous brands, such as Schneider from France,Carlo Gavazzi from Switzerland,Mitsubishi from Japan,Rainbow from Korea.

Safety features 

• Test sample overtemperature protection function.
• Circulation motor overload protection function.
• Compressor overload protection function.
• Compressor overpressure function.
• Heater/humidifier air burn protection function.
• Water shortage protection.
• Input power supply missing phase, reverse phase protection function.
• Lighting lamp / wire anti-condensation/no fuse independent protection switch in the secondary circuit.
• Electric leakage protection.
• Three color light alarm function.
• Test sample terminal and equipment chain control protection.
• Equipment fault shutdown, the cycle fan delay stop turn (delay can be set, 0 to 50min, default 5min).
• Non-metallic materials such as wire / cable / terminals / insulation materials / sound-absorbing materials (if sometimes) are made of flame retardant materials.
