| Application | Technology | Benefits |
| The new CRF condenser has been developed for HFC cooling applications at medium pressure (PS 30 bar) and high pressure (PS 48 bar) within refrigeration, process cooling and air conditioning. The secondary fluid is usually fresh water that can be in a closed loop with a cooling tower (tower application) or in an open loop with a well (city application). Some applications can use also glycol. These applications usually require a condensation temperature in a range of +30°C/+50°C depending on the system working condition and its efficiency rating. |
The CRF design has been optimized for R407C/F and R134a refrigerants but it can be also utilized with HFO1234ze, R410A, R404A and R507. Thank's to its new high performance tubes, new headers, new shell and the new baffles, the Alfa Laval CRF models provide maximum efficiency with a low cost/kW. This is an important step ahead compared with the current CDEW and CDEW-E models; the new CRF is ready to fight with competition. |
