Free Cooling Coil
A free cooling coil constructed in a “V” frame arrangement, allowing for efcient heat transfer from the ambient air
temperature to the cooling process.
The free cooling coil is manufactured from copper tube and aluminium n.
Free cooling is initiated whenever the outdoor ambient temperature is 2°C less than the return water temperature.
The “V” frame arrangement enables efcient concurrent cooling.
The DeltaChill Free cool chillers pipe work has been designed to optimise pressure drop. With this in mind the chiller is
more efcient in delivering a cooling solution.
Flow Proving Device
An evaporator differential pressure sensor facilitates low ow limiting and pressure drop monitoring via the
microprocessor shall be tted to ensure a correct unit water ow.
Pump Interlock
Provision for a pump interlock is available within the control panel.
Water Flow Switch
A water ow switch is tted ensuring integrity of the cooling solution ow
Water Filter
Water lters are tted to protect the evaporator from clogging by sediment. This is a standard feature with the DeltaChill
Free cool.
For standard Air Cooled DeltaChill the water lter is an optional extra
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 anged connections available on request, please consult Airedale.
The water ow switch or pump interlock must be tted in addition to the ow proving device to
validate warranty.
