Product Overview
The Huatai GDT-150BH Programmable High and Low Temperature Humidity Test Chamber is a testing device used to simulate high and low temperatures as well as humid environments. It provides constant or alternating temperature and humidity test conditions for products through a precise control system and refrigeration system.
Product Features
1. Utilizes a fully enclosed Tecumseh compressor from France and environmentally friendly refrigerants R404a and R23 from DuPont, USA.
2. Equipped with a high-efficiency sloped evaporator (AC&R compound turbulator aluminum fin) and a SWEP plate-type heat exchanger.
3. Employs advanced installation techniques such as nitrogen-flushed welding and pipe bender bending to ensure pipeline quality.
4. Features a comprehensive equipment safety protection system, including multiple protections for the compressor, humidification system, test chamber, and power supply.
5. Water-cooled condensing system for convenient equipment mobility.
Working Principle
The equipment achieves cooling through a compressor-based refrigeration system and provides heating and humidification via heating and humidification systems. The controller precisely adjusts the temperature and humidity inside the test chamber according to preset programs to simulate the required environmental testing conditions.
Application areas
Fields that require environmental reliability testing include electronics, automotive parts, materials research, aerospace components, military products, and more.
Complies with the standard

Operating Procedures
The specific operational steps are not provided in the information.
Precautions
• The installation site must have a level floor, good ventilation, be free of flammable, explosive, and corrosive gases, and have no strong electromagnetic radiation sources nearby.
• The site's load-bearing capacity should be no less than 500 kg/m², with maintenance space reserved around the equipment (Side A ≥ 30 cm, Side B ≥ 50 cm, Side C ≥ 70 cm, Side D ≥ 90 cm).
• Power requirements: Voltage AC (1 ± 5%) 380V/220V, frequency (1 ± 1%) 50Hz, protective ground wire grounding resistance less than 4Ω, and a dedicated independent air or power switch must be installed.
• A drainage floor drain must be available near the equipment (within 2 meters of the refrigeration unit).
• Distilled water, purified water, or deionized water with a resistivity greater than 500 Ω·m must be used for humidification (to be provided by the user).
• When the equipment is not in operation, the ambient temperature should be maintained between 0°C and +35°C (no freezing). If the ambient temperature drops below 0°C, drain the water inside the equipment to prevent pipe freezing and cracking.
• During testing, avoid frequently or keeping the chamber door open for extended periods to prevent temperature and humidity fluctuations or ice formation on the refrigeration system's heat exchanger, which may disrupt normal operation.
