ERM-2K3U Liquid Cooling System, Rev1.0

[Replaced By ERM-3K3UA]
Part No. ERM-2K3U_R0 This product is archived and displayed for information only. It is no longer available for purchase. Released: 13 January 2009

The ERM-2K3U continues Koolance's "ERM" series of dedicated liquid cooling systems for special thermal applications. It can provide up to approximately 2000W of potential heat dissipation, and is housed in a lightweight aluminum enclosure. A prominent white LED-lit reservoir displays the coolant level, combining a waterfall effect when placed upright.

Heat sources from multiple computers can be connected to a single ERM-2K3U system if within the total dissipation rating. The ERM-2K3U utilizes a single PMP-450 pump. A large louver-fin heat exchanger stretches diagonally from front to back, cooled by two 220mm blue LED side fans, and five low-flow 80mm rear fans.

The cooling system can be configured in multiple ways. Wide feet are included for vertical operation in a "tower" position. Post feet allow a horizontal installation, with fans facing up or down. Alternatively, the unit fits within a 3U profile and rack mountable ears are included. The LED readout can be conveniently rotated for any position. (NOTE: 3 bottles of coolant is recommended for the ERM-2K3U.)

Other features:

  • Variable pump speed via the front display
  • Rear G 1/4 BSPP inlet and outlet fitting sockets
  • Radiator fan speeds adjust automatically, or with 10 manual levels
  • White reservoir LED lighting (can be switched on or off)
  • Top coolant fill plug
  • Independently-variable alarm and safety shutdown temperatures on all three sensors
  • Adapted power connection - does not require an AC power outlet

Liquid Coolants

Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth. Additionally, do not use aluminum with bare (unplated) copper or bare (unplated) brass in the same system. Do not use silver with nickel in the same system.
