Chillers
TurboChill™ R513A Air Cooled and FreeCool
Free Cooling Coil
A free cooling coil constructed in a “V” frame arrangement, allowing for efficient heat transfer from the ambient air
temperature to the cooling process. The free cooling coil is manufactured from copper tube and aluminium fin. The
TurboChill free cool chiller’s pipe work has been designed to optimise pressure drop, reducing pump input power. It shall
be fitted with a water drain valve (schrader point located at lowest point of coils) for maintenance purposes.
Free cooling is initiated whenever the outdoor ambient temperature is 2K less than the return water temperature. The
“V” frame arrangement enables efficient concurrent cooling.
Water Filter
A 20 mesh water filter can be supplied fitted to protect the evaporator from clogging by sediment. On certain models the
filter is fitted externally.
Grooved and Clamp Type Connections
Grooved and clamp type connections shall be fitted to the unit.
*
Each feature is a flow proving device, and 2 out of the 3 should be fitted to any unit to validate
warranty.

Flanged Connections
Flanged connections shall be fitted to the unit upon request. (excluding TCC evaporator only hydronic options). Please
contact Airedale.
Pump Vibration Eliminator
Bellows shall be fitted to the pumps (>11kW) to reduce any vibration through the system pipework.
Pump Interlock*
Provision for a pump interlock is available within the control panel.
Water Flow Switch*
If selected. A water flow switch is fitted ensuring integrity of the cooling solution flow. The flow switch shall protect the
chiller against low water flow conditions. Despatched loose for on site fitment.
Flow Proving Device
An evaporator differential pressure sensor facilitates low flow limiting and pressure drop monitoring via the
microprocessor shall be fitted. This is to ensure correct unit water flow at all times during unit operation. If the water flow
is reduced a critical alarm is generated.
