Introduction
Chillers TurboChill™ 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.
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 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.
Flow Proving Device
An evaporator differential pressure sensor facilitates low flow limiting and pressure drop monitoring via the
microprocessor which shall be fitted to ensure correct unit water flow.
Water Flow Meter
A water flow meter shall be fitted to the unit to monitor water flowrates.
Grooved and Clamp Type Connections
Grooved and clamp type connections shall be fitted to the unit.
Flanged Connections
Flanged connections shall be fitted to the unit upon request. Please contact Airedale.
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. A 1” BSP socket is required for this fitment.
*
CAUTION
Each feature is a flow proving device and 2 out of the 3 should be fitted to any unit to validate warranty.
Pump Vibration Eliminator
Flexible couplings shall be fitted to the pumps to reduce any vibration through the system pipework.
