Environmental Chamber Heat / Refrigeration system |
Heating system |
Level, constant heat is continually maintained through a water media, by specially designed high purity magnesium oxide and helically wound nickel-chrome wire heating elements. Elements are totally enclosed for efficient heat transfer and operator safety. The warm air is evenly distributed throughout the chamber through efficient motor fans ensuring very good temperature sensitivity. |
Refrigeration system |
SPENCERS superior refrigeration system with optional Backup refrigeration system. Uniform refrigeration is maintained through the use of air-cooled, high torque, hermetically sealed condensing unit. High quality cooling system components include: efficient fan circulation evaporator coil with thermal expansion valve, moisture-liquid indicator, filter drier, heat exchanger, and pressure control valve. All refrigerant lines are copper and fully insulated. |
Compressor |
Heavy duty Air-cooled compressor. The compressor is distinguished by its excellent performance, low noise level (<60dB) and minimal vibration. |
Condenser |
Highly efficient condenser with automatic condensate evaporating system. |
Evaporator |
Internal evaporator system Forced draught. |
Refrigerant |
Non-CFC/HCFC environmental friendly based on compressor capacity. |
Air Circulation |
Forced air circulation to maintain chamber uniformity. |
Environmental Chamber Air-Humidity Circulation |
Humidity System |
Unique forced air circulation design maintains an even, continuous, moist airflow throughout the cabinet. Perforated trays further enhance even humidity distribution to testing samples. Self-contained stainless steel water reservoir in each chamber assures a relative humidity of 90%. Temperature
variation between trays is ±0.5° C, top to bottom. |
Environmental Chamber Control System |
