Laboratory IEC61215 Walk-in High and Low Temperature Chamber for PV Modules
1. Environmental Walk-In Test Chambers Advantages:
Structure:
To ensure the housing metal sheet flat and precise. We use the Germany TRUMPF metal processing machine. Automatically control laser cutting. You can feel its good flatness.
Our housing is steel plate galvanized and zinc painted inside.
To keep its outstanding appearance in long term service, we apply the coating technology of automotive for the surface treatment:
Acid-cleaning, coslettise, drying, spraying, baking, then packing back.
This technology hardly causes coating damage. Long time no-lose color.
It's easy for cleaning and maintenance.
Refrigerating System:
For enhance the whole refrigerating system performance, we use professional and advanced copper tube bending machine, this can decrease the welding points over 50%, and decrease right-angles of the tube, Also less welding points can reduce the resistance when the liquid flowing inside, to keep compressor working in higher efficiency, and better energy-saving.
And for welding the copper tube, we use Liquid Nitrogen protection welding technology, this can better protect the tube and keep the cooling system clean.
All this will do good to the compressor. we use the GEA Bock compressor (made in Germany) for the walk-in chamber.
Water and electricity system separating design:
For improving the comparable fragile part, heating part of constant high damp heat test, we apply water and electricity system separating design, to keep the water and electricity system separated with external humidifying system, and use top brand(e.g.: DANFOSS, Schneider, Danfoss, Emerson, Saginomiya, etc. ) for all electronic components to make sure the chambers' quality and service time.
Walk-In Chamber Features:
1. Heat preservation material, we use high-intensity PU foam with flame retardant material and high density glass fiber cotton, which can assure high precise and better uniformity and avoid unnecessary energy loss. Meanwhile, our design can better assure personnel safety when operating a Walk-in Chamber.

2. Large glass window design, viewing angle in all directions, hollow electric plating film and anti-condensation design; built-in LED lights to facilitate the test sample state of real-time observation in the course of testing; double door design, the inner big glass door with hand-in holes for the convenient operating.
3. Material quality of inner box is SUS304 # mounted stainless steel imported, and outer box is steel plate and the paint process applies automobile coating technology. Box body is processed shape using Triumph processing machine, its shape is nice and neat.
4. Large-size Full Color LCD touchscreen displayer, simple operation, easy to edit programs. PID with automatic calculation function; self-diagnostic function, show failure message and failure shot solutions step by step.
5. An RS-232 and RS-485 communication interface, matching recorder, strong expandability. We also support remote control by PC via wifi or wire (recommended).

4. Control method and characteristics:
Precision microcomputer control temperature and humidity system, with PID, control the refrigerant flow to make the system's heating/humidification reduction, to achieve low power consumption, energy-saving, carbon reduction effect, cooling, heating, humidity control intelligent electronic control, long-term stable use.
Flexibility for structure
The panels used in our chamber are 4" (100mm or 150mm) Thick urethane-foam sandwiched between a stainless-steel interior wall and a coated-steel exterior. An assembled box is self-supporting. So that no heavy structural members are required. Different door sizes, flooring upgrades, access ports, and other modifications are possible.
