evapcold

The Evapcold LCR-P product line is based on a penthouse configuration and includes 250 models that have an ammonia charge ranging from 2 to 6 lbs. per TR (actual charge amount dependent on the model size). The LCR-P is specifically designed to be roof mounted on the refrigerated space. Penthouse units are available with Pumped Recirculated Liquid (PRL) ammonia evaporators for low and medium temperature applications, or Direct Expansion (DX) evaporators for medium and high temperature applications.

EVAPCOLD LCR-P

  • Capacity of 10 and 100 TR
  • Room temperatures ranging from -20ºF to +70ºF
  • Water-cooled or air-cooled condensing
  • Hot gas defrost, air defrost or no defrost
  • PRL models are a great match for freezers and coolers
LCR-P Penthouse Units – Evapcold Advantages
  • Very low ammonia charge of 3 to 6 lb/TR depending on model size
  • Hot gas defrost on all low & medium temperature models: the most efficient defrost method, and allows units to continue running while in defrost mode
  • Very efficient and reliable evaporator operation with low 1.2:1 pumped liquid recirculation rate, or DX for medium and high temperature applications
  • Personnel access to penthouse evaporators is separate than access to machine room
  • Insulated “Superfloor” under machine room eliminates need for roofer to perform this work
  • EVAPCO self-performs 100% of the packaging scope of work
Major Items Included
  • Variable speed screw compressor package for efficient operation
  • Water cooled condenser (w/ water regulating valve) or air cooled condenser
  • Flash economizer for economized compressor on medium and low temperature models
  • Recirculator with pumped liquid refrigerant supply, or DX for medium and high temperature applications
  • Insulated penthouse evaporator section featuring hot gas defrost or air defrost
  • Stainless steel refrigeration system piping
  • Control panel completely wired and enclosed in machine room
  • Ventilation fans and intake louver for ammonia purge & heat removal
  • Lighting in machine room & penthouse
  • Room heater in machine room
  • Ammonia relief valves and piping header system
  • Ammonia detection
  • Insulated enclosure walls
  • Insulated refrigeration piping, including all required pipe labels and valve tags
  • Enclosure finish – galvanized steel
  • (1) - 460V Electrical feed to each LCR package for easy electrical hookup
  • All electrical power & control wiring within the LCR package is complete
Easier & Lower Compliance Costs for Owners & Operators

Evapcold provides inherently safer technology, reducing the regulatory burden to owners and operators, and lowering compliance costs.

  • Contains significantly less ammonia and are safer to operate, maintain & work around
  • Allows owners to stay below 10,000 lb Threshold Quantity mandated by OSHA’s PSM and EPA’s RMP regulations
  • Lowers the off-site consequence analysis required by EPA
  • Reduces liability & exposure to fines
  • EVAPCO provides operating & maintenance procedures, product hazard review, tagging, labeling & signage
  • The Evapcold complies with applicable code and standards
Lower Energy Consumption

The Evapcold product can reduce a facilities energy consumption and attain annual energy savings up to 15% as a result of the following:

  • Variable Speed Drives (VFD) on every compressor, NH3 pump and condenser fan (for air-cooled models) and also optional on the evaporator fans
  • Room temperature is directly connected to its own compressor suction, not a “house” suction that may be common to different room temperatures
  • Evapcold packages eliminate refrigerant pressure drops associated with long piping runs
  • Evapcold built-in software in conjunction with supervisory control system provides superior energy management

All of the above add up to real energy savings over the course of a year compared to traditional ammonia systems. In addition, the LCR units consume significantly less energy than Freon systems.

Several optional accessories are available with the Evapcold refrigeration system to allow you the flexibility to select the configuration best suited for your application:

  • Variable frequency drive for evaporator fans
  • Penthouse supply air ductwork
  • Penthouse lighting
  • Penthouse ammonia detection
  • Motor davits for evaporator fans & condenser fans
  • Machine room winterization
  • 3-Way water regulating control valve
  • Remote control of LCR packages and supervisory computer system
  • Emergency Pressure Control System
  • Adiabatic cooling pads on air cooled condenser
Maintenance Accessories

The Evapcold LCR system is designed with significant features to facilitate easy maintenance by the inclusion of:

  • Evaporator penthouse access doors
  • Evaporator fan/motor removal davits
  • Exterior Service Panel on machinery room including the ability to connect a pump-out unit
  • Monorail and hoist for compressor or motor removal, as well as an access panel
  • “Walk-in” machinery room includes the required maintenance access for all components, maintenance is performed indoors on the roof instead of outdoors
  • Stainless steel piping, eliminating pipe corrosion
  • Isolation valves on major equipment
  • Cable tray for wiring for easy access
  • PAO compressor oil for effective oil return
Easier maintenance and training attributes of the Evapcold units including:
  • The operational hazards for an owner are identified earlier through EVAPCO’s product system testing, development and system improvement
  • Pre-engineered, manufactured and tested Evapcold systems are simpler to operate than custom built field erected ammonia refrigeration systems
  • Every system is NOT different as is the case with traditional systems. Common system designs and components make training and maintenance easier
  • Complete documentation and maintenance procedures are provided with every unit
  • Concise, consistent and repeatable operating procedures are already written for the Evapcold products

The net effect of the above items is the maintenance cost for Evapcold LCR systems will be lower than traditional systems.
