Enviromental Test Chamber 1260 L High-Low Temperature Test Chamber
Structure
The whole structure, that is, test box, refrigeration system, air
conditioning system, electrical control cabinet, refrigeration unit
as a whole, the refrigeration unit is located in the bottom of the
box, electrical control part of the side of the test chamber, easy
to operate.
2 The box:
A) the end of the studio in the duct sandwich, the distribution of
heaters, refrigeration evaporator, blast motor, fan and other
devices;
B) The test box side with a cable threading hole 1, size ф50mm;
C) The test chamber is made of 1mm thick SUS304 stainless steel
plate. The box shell is made of 1mm thick cold plate
D) insulation material using polyurethane foam, thickness 100mm,
good insulation effect, the outer surface of the test chamber does
not frost, do not condensation.
E) The studio is equipped with four adjustable mesh partitions;
each size 1400 (length) * 600 (width) * 375 (high), 4 layers
F) The tank is provided with a condensate drain.
3 The door:
Double door, door seals are used double-wire silicone rubber seal;
4 Observation lighting device:
The door is equipped with a multi-layer insulating glass
observation window, the size of about: 300 × 275mm, and a heated
anti-frost device. A (AC12V) 20W halogen lamp is installed on the
