Precision Cooling for Business-Critical Continuity™ Liebert HPM Dual Circuit Floor Mount Chilled Water Units for High Redundancy Redundancy To Secure Your Business Liebert HPM R-type units are dual circuit chilled water units for business critical applications. Equipped with two independent chilled water circuits they are able to take cooling fluid from two independent sources. The models are available in the cooling capacity range 24 - 120 kW for each circuit; each equipped with 3 or 2 Port valves. These units provide additional security for your critical environment. With primary and secondary chilled water circuits the units provide mandatory back up in terms of cooling capacity. Liebert HPM Dual CW Circuit Hydraulic System Schematic Liebert HPM Dual CW Circuit units are specifically designed for buildings with primary and secondary chilled water circuits. A typical application is for polyfunctional buildings where a larger cooling source operates during the day, serving offices, technology and datacentres; while at night when cooling is only required for the technology and datacentres we can use a smaller chilled water source, maximizing obvious energy savings. CW1 CW2 Availability 100% redundancy CW circuits Dual CW circuits with double power supply maximize availability. Flexibility Simplified design layout: • power cables • condensate drain • supply/drain for humidifier Secondary CW circuit can provide additional cooling in the event of increased heat loads 2 Low Total Cost of Ownership: Reduced footprint compared to two separate units Lower investments in airconditioners Lower cost for the installation iCOM - Keep it under control Control The sophisticated control logic of the units offers several options to satisfy the chilled water system requirements and valve management. Parallel mode The chilled water valve management and positions are the same for both CW circuits. Safe mode First circuit and valve managed utilizing 70% of proportional temperature band, and then second valve starts to open (Requires same inlet fluid temperature on both circuits). Alternate mode With an external input to the iCOM controller it is possible to manage which of the two chilled water circuits / valves is duty and which is standby. In parallel and safe modes both CW circuits can run together maximizing the cooling capacity.
