EHDC Cooling units CW


EHDC S1 is a range of high density row cooling units. EHDC S1 is available in a variety of configurations. Both CW (Chilled Water) and DX (Direct Expansion) units are available. The CW units are available in 2 widths, 300 and 600mm. 3 air distribution models are available – Open Loop, Open Loop-Horizontal Distribution and Closed Loop.

The cooling units are installed in an S1 frame, giving the cooling units the same design and functionality as the S1 Server racks around. The EHDC S1 together with S1 are ideal for aisle containment with KKD and KKT from Enoc System.

  • CW cooling unit
  • Dual Power: In case of main power supply lack, units are provided with automatic switching on an emergency line.
  • Fan Hot Swap: Through fan switches on a multiswitch bar, power supply of each single fan can be interrupted to allow maintenance operations, while the other fans keep on working. 
  • CW valve with proportional control: The CW valve receives a modulating signal from the C2020 controller to vary the water flow through the heat exchanger, in order to adjust the unit cooling capacity to the actual heat load. CW valve is available in two versions: 3 way valve for constant flow system, and 2 way valve for variable flow system.
  • C2020 controller is installed on board the EHDC-S1 to manage all functions. The keypad is the user interface, which allows to display operating states and alarms. 
  • AC fans or EC fan as option: It is possible to equip all models with EC fans. EC fans operates more efficient than AC fans. EC fans has continuous modulation of speed and also low noise level at reduced speed. 
  • Condensing pump is standard on version with piping connection from the top.
  • Network Management: The EHDC-S1 solutions for networking allows a continuous and efficient monitoring for airconditioning systems. Network Management allows the adjustment of set points, plant monitoring and display of operating parameters on two different control units, PC or on-site BMS.

  • Screw-assembled frame with aluminium profiles and die-cast zinc corners. The same design and functionality as the S1 server rack from Enoc System.
  • Finish: Black RAL9005.
