Rack Mounted
Temperature/ Humidity
Sensor Rack mounted temperature and Humidity sensor shall be supplied as standard. This
shall be supplied loose for onsite fitment in a customer rack.
Leak Detection Leak detection for the water system, able to report alarm status to the BMS system shall
be provided. The unit shall then be shut down before any damage occurs.
The leak detection tape shall be fitted within the drip tray of the coil.
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).
EC Fan Nodes The fan nodes enable independent control. The fan can be interrogated by the controller
giving information such as temperature, fan speed, currents and power consumption.
If during a controller failure the fans resume operation at the last setpoint. This ensures
downtime is reduced.
