Humidity test chamber ST series
Product catalog summary
System Overview: The Balanced Temperature and Humidity Control (BTHC) system is designed to maintain precise environmental conditions with a temperature range of -70 to +100°C (extendable to +150°C/+180°C) and a humidity range of 20 to 98% relative humidity (rh). The system ensures temperature fluctuation within ±0.3°C and humidity fluctuation within ±2.5% rh, with a temperature uniformity of 1.5°C.
Performance Specifications: The system features a heating rate of 3.0°C/min and a cooling rate of 2.0°C/min. It can reach extreme temperatures from +20 to +100°C in 30 minutes and from +20 to -70°C in 60 minutes.
Structural Details: The external structure is made of 1.5mm thick FC advanced electrolytic plate with plastic spraying for corrosion protection, while the internal structure uses 1.2mm thick SUS304 stainless steel. The system includes a fin-type nickel chromium alloy explosion-proof heater, a stainless steel jacket humidifier for steam humidification, an air-cooled condenser, and a centrifugal fan for air circulation.
Water Supply: The system is equipped with an automatic makeup water tank with capacities of 10L, 12L, and 15L depending on the model.
Refrigeration Unit: The mechanical cascade compression cooling system uses scroll/piston compressors and refrigerants R404A & R23, with alternatives R449A & R508B available upon request. Power consumption varies from 2.3 Kw to 6 Kw, and the system includes an electronic expansion valve.
Model Specifications: The system is available in three models with volumes of 64L, 180L, and 340L, and load capacities of 30KG and 50KG. Inner dimensions range from 340x340x500 mm to 580x765x750 mm, and external dimensions from 820x1440x1510 mm to 1050x1910x2010 mm. Weights range from 400kg to 640kg.
Operating Environment Requirements: The system operates in ambient conditions of 0 to +40°C (32 to 104°F) with a maximum humidity of 75% rh. Power requirements include 1φ220V AC 50Hz/60Hz and 3φ380V AC 50Hz/60Hz, with noise levels maintained at 68dB.
