Walk-in Cold/Freezer Room

Integral Cold Store Unit

• The cold room is suitable for a variety of applications; it can be used to freeze or refrigerate samples for healthcare, research, agriculture, and biotechnology purposes. In the walk-in cold room (WIC), the interior temperature can be controlled within a range of 2°C to 8°C. In the walk-in freezer (WIF), the temperature is set at -20°C.

Technical Characteristics of the Refrigerating Unit

• An integrated condenser unit, called Mono block, integrating evaporator, condenser, compressor, electrical control units into one compact body, is used in cold storage rooms with temperature control of -5°C~5°C or -15°C~-20°C, in medical, clinical, agricultural and chemical industries where large scale cold storage is needed.

• Small compact structure.

• Comprises of TECUMSEH hermetic compressors, hight efficient, in-grooved copper tube and aluminium fin heat exchangers and leading brand refrigeration parts.

• The electronic control boards manage following parameters: automatic temperature setpoint and control,

electric heater defrosting, protection devices for over loading, over-heating, lack of phase, high and low pressure.

• Safe, easy to use and is economical, low cost installation and operation.

Temperature Recorder

• Upper and lower limits +50°C to -30°C

• Accuracy ±1°C

• Resolution ±0.5°C

• Minimum acceptable recording period between chart changes is 7 days

• USB interface is included
