Close control units are specially adapted to meet the needs of rooms with a high heat load or sensitive locations as data center, computers rooms, sensitive storage, medical rooms, etc.. Cooling capacity (kW): 5-47. Air flow (m3/h): 1300-12000. Cooling capacity (kW): 40-130. Air flow (m3/h): 10000-27000.
FlowCon recommends two different solutions to a CRAC unit installation: 1. CRAC Units with Pressure Independent Temperature Control (PITCV) The PITCV will react only to change in ΔT, which can be either deliberately set to a new target or automatic due to occupancy change. The PICV actuator will only move if a ΔT change is sensed.
2023年8月16日 · Different CRAC Unit Design Configurations There are a few configurations that will be seen, depending on the room construction, as noted below: Down flow configuration A ‘Down flow’ unit is one where the air is removed from the space through the top of the equipment, drawn downwards, where it is conditioned prior to being blown back into the space via the lower frontal section of the unit.
CRAC System Direct Expansion Close Control Units With Remote Condensers- Refrigerant R410a Canovate’s CRACs (Computer Room Air Conditioners) are designed for use in data centers, data processing rooms, telecom centers and other applications where keeping the keeping thermo-hygrometric conditions constant year-round is important to ensuring the correct operation of electronic devices.
Fan Coil Unit for Low Static Pressure. PETRA’s fan coil units (RAC Series) are designed for applications with low static pressure. The units are particularly suitable for concealed or exposed ceiling or floor applications with ducted air distribution. This series covers an airflow range from 94 to 566 L/s (200 to 1200 CFM).
HIMOD units can be supplied with an exclusive fan type, which enables you to greatly increase the unit’s efficiency and therefore significantly reduce operating costs. EC fans [Electronically Commutated DC motors] have the added advantage of higher motor efficiencies, up 45% higher than three phase and 65% higher than single phase motors.
