Supplier:
  • A grey enamel or optional NEMA 4X stainless steel enclosure contains all branch power, switching and control circuits. This panel serves multiple freezers from a single central control location.
  • The front features a heavy-duty insert section with Lexan door and key lock. The controls, recorder (if purchased) and non-fade labeling can withstand light spray down.
  • The panel is third party listed to UL standards. NEC code is strictly followed for internal and external panel wiring.
  • Temperature is controlled by a high accuracy, digital PID controller. This type of controller allows for close temperature control through proportional-integral-derivative algorithms (not on-off control).
  • Alarm settings, solenoid actions, system auto-switching, mechanical enabling and other various parameters are controlled through the proprietary CCS touch-screen control system.
  • Alarms are indicated by LCD screen and other highly visible panel-mounted indicators; audible alarms are also standard. Dry contact outputs are standard for temperature alarm limits and may be provided, by request, for other indications.
  • Mechanical refrigeration ‘skids’ serves multiple freezer vaults inside walk-ins or multiple upright reach-in / chest style freezers.
  • Refrigeration skids are designed to be compact, yet offer generous service spacing. Strategic thermocouple locations (and display panel) allow for temperature readings important for servicing.
  • Copeland scroll compressors offers a multitude of advantages over reciprocating compressors: lower energy usage (high COP), fewer moving parts, fewer wear and stress points, lower noise, lower vibration, physically smaller and higher coefficients of performance. The scroll systems use non-CFC refrigerants.
  • Super-high efficiency oil separators remove 99.9% of circulating oil; oil removal is essential for trouble-free compressor operation.
  • Thermostatic expansion valves allow precise metering of refrigerant.
  • Dual, identical mechanical systems alternate regularly for even wear and automatically switch systems based on detected system fault. Product protection is essentially guaranteed with redundancy.
