Walk In Environmental Test Chamber BTHW series

Product catalog summary

Standard Compliance
The Walk-in Temperature Test Chamber complies with several international and military standards, including IEC68 series and MIL-STD-810D, ensuring its reliability and accuracy in environmental testing.

Performance Parameters
The test chambers are available in various models with different test space dimensions ranging from 2000x2000x1500 mm to 4000x2500x8000 mm. The external dimensions vary accordingly. The temperature range is categorized into four types: A (0~90°C), B (-20~90°C), C (-40~90°C), and D (-70~920°C). Humidity ranges from 20%RH to 98%RH, with low humidity options available at 5%RH.

Temperature and Humidity Control
The chambers maintain precise environmental conditions with temperature fluctuation ≤ ±0.5°C, deviation ≤ ±2°C, and uniformity ≤ ±2°C. Humidity fluctuation is ≤ ±2.5%, with deviation ≤ +2/-3%RH for humidity >75%RH and ≤ ±5RH% for humidity <75%RH. Heating and cooling rates are approximately 1~3°C/min and 0.5~1°C/min, respectively.

Materials and Construction
The internal material is 1.0mm thick SUS#304 stainless steel, resistant to high and low temperatures. The external material is a 1.2mm thick high-temperature spray powder-coated galvanized plate.

Compressor and Options
The chambers use Tecumseh (France) or Bock (Germany) compressors for cooling. Optional features include a dry air purge system, humidifying water auto-purifying system, new air ventilation system, and safety features like fire-proof and explosion-proof systems. Remote computer and mobile alarm functions are also available.
