LCP Extend rack cooling

Click2Contact

Rittal has expanded its Australian range of liquid-based server cooling systems with the LCP Extend, an air/water heat exchanger unit that can be fitted to rack rear doors.

The unit is based on air/water heat exchanger technology and solves the problem of high heat losses of up to 12 kW per rack. Without having to modify existing series of enclosures, LCP Extend can be attached as an independent cooling unit to rack rear doors even while the rack is still in operation.

The ready-to-connect cooling unit, which has the outer from of a climate control door, has a heat exchanger module and six hot swappable fans. The cold air supplied by the standard air-conditioning units is drawn through the servers and heats up. The hot air at the rear of the rack is then drawn in by the fans and passed over the air to a water heat exchanger where the energy in the air is transferred to the water in the coil.

As the warm air travels over the coil it is cooled down and re-enters the room as cold air. Warm water is then transported to a re-cooling system and cooled down before travelling back to the LCP as cold water. Water can be supplied to the LCP cooling unit either from the top or the base.
