Water Filter
Water filters are fitted to protect the evaporator from clogging by sediment. This is a standard feature with the DeltaChill
FreeCool. For standard Air Cooled DeltaChill the water filter is an optional extra.
Free Cooling Coil
A free cooling coil is manufactured from copper tube and aluminium fin and constructed in a “V” frame arrangement,
allowing for efficient heat transfer from the ambient air temperature to the cooling process. Free cooling is initiated
whenever the outdoor ambient temperature is 2°C less than the return water temperature. The “V” frame arrangement
enables efficient concurrent cooling. The DeltaChill FreeCool chiller’s pipe work has been designed to optimise pressure
drop so that it is more efficient in delivering a cooling solution.
Flow Proving Device
An evaporator differential pressure sensor shall be fitted to ensure a correct unit water flow. This facilitates monitoring of
low flow limits and pressure drop via the microprocessor.
Water Flow Switch
A water flow switch is fitted ensuring integrity of the cooling solution flow.
Pump Interlock
Provision for a pump interlock is available within the control panel.
Water Connections
Water inlet and outlet connections are of a grooved and clamped type construction. The unit is supplied with a counter
pipe and coupling assembly for quick connection. Optional flanged connections available on request, please consult
Airedale.
IMPORTANT
The water flow switch or pump interlock must be fitted in addition to the flow proving device to
validate warranty.
