Introduction |
The C55-EU is mainly developed as evaporator for high efficiency chillers using R407C/R404A/R134a or other low pressure refrigerants and |
||||||
covering cooling capacities 10 to 65 kW (3-18 Rt), but it can also be used as economizer. Equipped with Power Bulges - an innovative distribution system - the evaporators enables a perfect refrigerant distribution, thereby improving heat transfer, minimizing pressure drop and being less sensitive to inlet connection and pipe size. It is based on the well proven MPHE technology, meaning minimal refrigerant charge and less weight for both environmental and financial savings.
Key features |
• |
Low hold up volume refrigerant side; less refrigerant charge in the system |
|
• |
Lower weight; less sensitive to raw material price fluctuations and reduced CO2 footprint |
|
• |
Unique refrigerant distribution system, Power Bulges; |
|
• |
Less sensitivity to inlet connection and pipe size |
|
• |
Low pressure drop on refrigerant side |
