Cooling Mode - Chilled Water Cooling (C0)
Standard Features
Chilled Water Coil
3/8” plain tube cooling coil with 1.8 mm n pitch and hydrophilic ns.
Dependant on model the coil shall be single (C0) or dual circuit (CC).
Bleed and Drain Valves
Valves shall be factory tted to easily bleed the system of any air and drain water for maintenance.
Bypass Regulating Valve
A bypass regulating valve shall be tted in the bypass leg of the system to enable constant ow when there is no cooling
demand. This simulates the coil pressure drop ensuring that the water ow rate does not change irrespective of the ow
through the chilled water coil.
This enables ow through each cooling module without the need for a Cooling Distribution unit (CDU).
Optional Features
0-10 Volts DC Chilled Water 3 Way Valve
A 0-10 VDC chilled water 3 way regulating valve shall be tted. This shall be used
to govern the chilled water ow to the coil when there is a demand for cooling.
0-10 Volts DC Chilled Water 2 Way Valve
A 0-10 VDC chilled water 2 way regulating valve shall be tted.
This shall be used to govern the chilled water ow to the coil when there is a
demand for cooling.
Isolating Solenoid Valves (C0 Only)
Isolating solenoid valves shall be tted to the inlet and outlet connections. This
shall control the water ow to and from the cooling module in the event of fault
or power failure. The valves have a low pressure drop and are fast acting. The
valves shall be Normally Closed (NC) operation.
Leak Isolation Valve (CC Only)
A combination of the chilled water valve and a non return valve shall be tted to
ensure water isolation in the event of fault or power failure. The valve has a low
pressure drop and fast acting.
