CRAC Units Computer Room Air Condition with Pressure Independent Temp. Control Controller CRAC Unit Pump Pressure Temp. Intelligent FlowCon Sensor Sensor Interface App PICV System Functionality: CRAC units are commonly used in data centers and other critical installations like clean rooms requiring high precision air conditioning. It consists of a direct expansion refrigeration cycle, and air is blown over a cold coil in order to achieve cooling. Without prop- er balance and control, necessary A/C is far from achieved. This can be prevented by installing a true pressure independent temperature control valve (PITCV) on every CRAC unit. The PITCV will, by con- trolling based on ΔT alone, help significantly to reduce energy consumption and operating costs, secure the essential high precision air conditioning and provide monitoring benefits (BTU etc). Requirements: A PITCV will only react to ΔT changes and conse - quently adjust the flow by altering actuator position. System pressure fluctuations are mechanically ab- sorbed by the included PICV. By controlling CRAC unit performance on ΔT, flow requirements may be re - duced, resulting in significant energy savings and still maintaining the proper room temperature at all times. Solutions: The solution is to mount a PITCV on every unit and FlowCon offers: • FlowCon Energy FIT System. Benefits: • All-in-1 solution incl. PICV, temperature and pressure sensors, flow and BTU metering. • User friendly w/ easy direct setting on display actuator (FIT) or direct flow setting on insert or valve (FIT-G) • Complete overview of energy and flow with simple monitoring via Bluetooth ® to FlowCon App or via BACnet to BMS • No piping restrictions - the most compact system on the market • Cost savings due to optimized energy consumption and improved efficiency • True PITCVs with full pressure independent ΔT control.
