Large CFC Free Refrigerant Temperature and Humidity Test Chamber 27.1 Cubic

Easy Assembling 27.1 Cubic Walk-In Temperature and Humidity Chamber

1. Temperature Ranges

Various ranges can be provided, including fast change rates with your product load. Ranges from -60°C (-140°F) to +85°C are available.

2. Humidity

2.1 Humidity Range:

Standard ranges available are: 20% to 95% ±5% RH. 10% to 98% ±2% RH.

Different ranges available including special dehumidity ranges to 5% RH.

2.2 Humidity System

Two Humidity systems are standard:

1) Fine Mist System is recommended when doing continuous testing with high live loads.

2) Steam Generator System is recommended for rooms being used for low and high humidity testing within the System range of +5°C ( +40°F ) to +55°C ( +130°F) .

The conditioned Fine Mist System uses your local water supply. Steam is created within a plenum outside the room area by spraying a fine mist over a stainless steel sheath-type heater. The circulation system carries this steam throughout the walk-in room.

The Steam Generator System uses an external self-contained steam generator with all necessary safety and water level controls to provide humidities to saturation point within the walk-in room.
