Notes
1. Desuperheater water type heat exchanger ∆T = 10K.
2. The water exchanger is protected against freezing down to -20 °C (with the Water exchanger frost protection option or Hydraulic module (if present) or loop protected
by an antifreeze solution for outdoor temperatures of less than 0 °C)
However, the customer is responsible for protecting the desuperheater water type heat exchanger water loop at outdoor temperatures below 0 °C
3. Operating ranges are guidelines only. Verify the operating range with the electronic catalogue.
