HE
Tube–in–tube heat exchanger, type HE is used primarily for heat transfer between the liquid and suction lines of the refrigeration plant.
The purpose is to utilise the cooling effect, utilise which without a heat exchanger is otherwise lost to the ambient air via uninsulated suction lines. In the heat exchanger, this effect is used to subcool the refrigerant liquid.
Features and benefits
- High refrigeration capacity in evaporator
- Helps ensure vapor–free liquid ahead of the expansion valve
- HE 0.5–1.5: may be used in the following EX range – category 3 (zone 2)
- Maximum utilization of the evaporator upon setting the thermostatic expansion valve for minimum superheat
- Helps prevent sweating and frosted-up suction lines
