Operating range 35% ethylene glycol
Evaporator leaving water temperature, °C
Notes
1. Evaporator ∆T = 4 K max. - condenser ∆T = 5 K
2. Operating range applicable for full and reduced load
3. At full load with a condenser entering water temperature below 20°C, a three-way valve must be used to maintain the correct condensing temperature.
Legend
C Unit operating with a condensing pressure control with an analogue water control valve.
For transient operating modes (start-up and part load), the unit can operate down to a condenser water temperature of 13°C.
D Operation permitted, but performances is not optimized
