Chiller can be ordered with an optional integrated
hydraulic module. In this case, chiller will be provided
with the following components factory mounted and
tested:
• Twin centrifugal water pump, Low pressure or High
pressure (option)
• Water strainer to protect the pump against impurities in
the circuit
• Expansion module with expansion vessel and pressure
relief valve sufficient to ensure the expansion of the
water loop ability
• Thermal insulation for antifreeze protection
• Balancing valve for equilibrate the flow of water circuit
• Drain valve
• Temperature sensor
Note: A pressure switch device to detect lack of water
is not included in the pump package. Installation of this
type of device is highly recommended to avoid sealing
damage due to operation of pump without enough water.
