Psychrometric Test Chambers

Dual-Chamber Environmental Systems for HVAC and Thermal System Testing

Aralab’s Psychrometric Test Chambers are purpose-built environmental rooms designed for the development, testing, and performance evaluation of air conditioners, heat pumps, gas boilers, and similar HVAC systems. These sophisticated systems simulate highly controlled indoor and outdoor environments, allowing for precise and repeatable thermal, humidity, and airflow testing according to international standards.

Commonly configured as a dual-chamber system, the setup enables independent control of two environments—typically one representing indoor conditions and the other outdoor conditions—with seamless integration of enthalpy measurement tunnels or third-party test rigs where required.

Key Features

• Dual-Zone Design:
  • Independent Indoor and Outdoor chambers for parallel simulation
  • Integrated control of temperature, humidity, and airflow
• Customizable Configuration:
  • Chamber dimensions and performance parameters fully customizable
  • Compatible with enthalpic test tunnels and third-party systems
  • Optional ATEX protection features available for hazardous testing setups
