Dual Cooling Source Precision Air Conditioner (CRAC)
The Smardt AIR Dual Cooling Source Precision Air Conditioner (CRAC) combines free cooling and compressor cooling in one unit. Its first choice is warm water from a cooling tower or dry cooler, with no compressor running. When conditions can't carry the full load, a built-in compressor circuit makes up the difference. It suits data centers, electrical rooms and other spaces that need close, continuous temperature control.
Key Performance Advantages
High Efficiency
EC fans adjust speed to the load. A DC variable speed scroll compressor keeps part load efficiency high. Hydrophilic aluminum fin, copper tube coils improve heat transfer.
Precise Control
PID control holds temperature within ±1°C (±1.8°F). An electric valve regulates water flow; optional EPIV or EV valves measure and control flow directly. Live status of every component is displayed. RS-485 communication comes standard.
Reliable
High-reliability components and a protected control system for continuous operation.
Maintain While Running
Controls and safety devices sit apart from the airflow, with all service from the front. Maintenance can be done while the unit operates.
