2 Way Chilled Water Regulating Valve
The chilled water valve has an indication of flow on the stem. The
actuator is securely attached to the top of the valve so that when
there is a demand for cooling the valve opens allowing water to flow
through the coil. No demand, the water is shut off allowing no water to
enter the coil (0 VDC no demand, 10 VDC 100% demand).
3 Way Chilled Water Regulating Valve
The chilled water valve has an indication of flow on the stem. The
actuator is securely attached to the top of the valve so that when
there is a demand for cooling the valve opens allowing water to flow
through the coil. No demand, the water goes through the bypass (0
VDC no demand, 10 VDC 100% demand).
2 Way PICV Valve
2-way pressure independent control valves, internally mounted 0-10V
DC PICV valves shall be used to compensate for pressure variations,
performing a continual balancing function to maintain system
performance at varying loads.
Bypass Regulating Valve
A bypass regulating valve shall be fitted in the bypass leg of the
system to enable constant flow when there is no cooling demand.
This simulates the coil pressure drop ensuring that the water flow rate
does not change irrespective of amount of flow through the chilled
water coil.
This enables flow through each cooling module without the need for a
Cooling Distribution unit (CDU).
Condensate Pumps
The InRak condensate pump shall be a cold water type (cooling only).
The pump shall be able to pump water 10l/hr @15m maximum head.
Pipework Termination
Pipework shall be terminated in either:
• Brazed Pipework
• Threaded Pipework Connection (BSP)
• Flexible Hose Connection
Flexible Hose Connection
A Flexible Hose connection shall be fitted to the unit. Length of 1.5 and 3m shall be avaliable. Hose ends can be either
Male or Female.
