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

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.
