System

The NH3 / CO2 cascade refrigeration system offers the ultimate solution for designing a sustainable refrigeration system. This system provides an HFC-free refrigeration solution for supermarkets while delivering significant lifecycle cost savings for retailers.

The NH3 / CO2 refrigeration system is a completely HFC-free system designed to deliver superior performance in food retail applications.

Compressor Controls

The compressor is the “heart” of the refrigeration system and has two main functions:
1. Maintain the pressure in the evaporator so that the liquid refrigerant can evaporate at the required temperature;
2. Compress the refrigerant so it can condense at a higher temperature.

Condensers

Condensers dissipate the heat from the refrigeration system to the surrounding air or water. Condenser control is essential for the efficient operation of the refrigeration system.

Level Controls

Level controls in the refrigeration system are critically important to ensure safe, efficient, and long-lasting operation. They prevent risks of overfilling or insufficient levels, enhance efficiency and performance, extend equipment life, and reduce breakdowns and maintenance costs.

Evaporator Controls

The evaporator is the part of the refrigeration system that transfers heat from the environment to be cooled into the refrigerant. The control system must ensure that the evaporator always operates efficiently and without issues.

Oil Systems

Generally, industrial refrigeration compressors are lubricated with oil; this oil is transported to the moving parts of the compressors through an oil pump or by pressure difference.
