Replacement of R-22

Commercial Refrigeration, Industrial Refrigeration, Food Processing, Direct Expansion Systems

For these applications, we recommend replacement of R-22 with a gas of the ISCEON® range. For low temperature applications: – 35°C, we suggest use of the ISCEON® MO29 - ISCEON® MO79 products. In most cases, ISCEON® MO29 represents the more cost-effective option. If higher capacity is required, ISCEON® MO79 is preferable although this retrofit will require additional steps (see the detailed conversion instructions).

ISCEON® MO79 also delivers additional cooling capacity compared with R-22 (up to 30% and 3 bar higher condensation pressure). However, in many cases, it will be necessary to adapt, modify or increase the size of the condenser. For medium temperature applications: - 10°C, we suggest use of the ISCEON® MO29 product. In some cases, if ambient temperature is high (above 35°C), ISCEON® MO29 may provide an 8% lower cooling capacity. In these cases, it is advisable to increase cooling efficiency, adding, for example, an internal heat exchanger.

Water chiller applications

For this type of application, we recommend the ISCEON® MO29 product to replace your R-22 refrigerant.

Stationary Air Conditioning Applications

For this type of application, we recommend the ISCEON® MO29 and ISCEON® MO59 products to replace your R-22 refrigerant.
