Overview

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.

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.
