low air pressure test chamber
Structural Features: With window design, it is convenient to observe the status of the test sample in the box. Adopt vacuum special composite pressure insulation material. Unique door lock design, easy to operate, good sealing. Lead holes are opened on both sides of the equipment to facilitate placement of measuring instruments and leads on both sides of the equipment. The inner box is made of SUS304 stainless steel. The outer box is made of manganese steel, and the surface is treated by electrostatic spray. The refrigeration system, waterway system and electric control system of the box have been modularized and separated for safe and reliable layout. The air supply mode in the box adopts 45 degrees oblique downward air supply, so that the temperature in the box quickly and evenly distributed, the temperature and humidity constant speed is faster, the Angle of the air guide vane can be adjusted freely, effectively ensuring the uniformity in the box. Refrigeration System Adopt international famous brand imported parts. Using R404A and R23 refrigerants with zero ozone layer destruction coefficient. The condenser is equipped with filtration device to ensure the unit runs reliably for a long time. Refrigeration system intelligent control, applicable to a wide range of loads, running less power consumption. Imported compressor: Copeland, Bock or Bizel, lower noise and more stable operation, stronger performance.
