Cold Rooms & 4 Degree Celsius Rooms

Cold Rooms & 4 Degree Celsius rooms are typically controlled between 2°C and 8°C with a control tolerance of ± 0.5°C or better. These rooms can be used as labs or for the storage of temperature sensitive pharmaceutical products. Humidity control systems can also be provided to maintain low moisture levels inside the rooms.

Room Construction

Standard wall, ceiling and floor panels shall be 11-1/2", 23", 34-1/2" and 46" in width and shall be interchangeable with the like panels. Standard heights of walk-ins with floors shall be 8'-5", 9'-5" and 10'-5". Corner panels shall be 90 degree angles with 12" exterior horizontal measurements.

Available standard heights without floors, with PVC Screeds are 8'-1", 8'-5", 9'-1", 9'-5", 10'-1", 10'-5".

Panels shall consist of "foamed-in-place" urethane insulation sandwiched between interior and exterior metal "skin" which has been die-formed and gauged for uniformity in size.

Edges of panels shall be "foamed-in-place" tongue and groove with locking facilities "foamed-in-place" at time of fabrication.

Floor Construction:

A. Floor Type: Panels shall be fabricated with 16 gauge stainless steel, designed to readily withstand uniformity-distributed loads of 600 lbs. Per square foot.

B. Floorless: Provide thermally effective PVC floor screeds. Screeds will be designed to hug floor surface and terminated in a coved radius at both interior and exterior floor joint, Flat-Bottomed Walls are also available and will sit directly on the floor surface.

SIZES: Standard and custom from small step-ins to large drive-ins; modular design allows customer to determine the best fit.

Conditioning Equipment

Airmont's condensing units are designed and manufactured to fit your needs. Condensing units for Cold Rooms will be single stage and can be supplied in either air cooled or water cooled. We use heavy duty industrial semi-hermetic or hermetic compressors for maximum reliability.

Airmont offers internal evaporator/blower or remote air handling systems. All systems will utilize solid state proportional control valves to precisely control the room temperature. Redundant conditioning systems with automatic switchover can be supplied for critical applications.

Controls

At each room is a direct digital controller to measure box temperature (and optional humidity) and status of the compressors. Output relays control the evaporator fan (usually kept on except for maintenance, safety or defrost) and the liquid line solenoid valve for system on/off and low temperature safety. Actual temperature regulation is accomplished by precisely modulating a hot gas bypass valve located before the evaporator coil. The refrigerant control valve is a high performance magnetically actuated three way bypass valve. The valve resolution is 10x that of a commercial control valve and has enhanced response time and stability. Operating parameters are programmed into the controller. Whether connected or not to the network, each controller acts to maintain the set point of the connected coolers.
