Chilled Water Precision Air Conditioner (CRAH)
The Smardt AIR Chilled Water Precision Air Conditioner (CRAH) provides close temperature control for data centers and other critical rooms. It connects to a central chilled water plant, so there is no refrigerant in the room and no outdoor unit to install. EC fans and high-efficiency coils deliver high cooling capacity at low energy use.
Key Performance Advantages
Energy Efficient
Backward-curved EC centrifugal fans adjust speed automatically to match the load. Hydrophilic aluminum fin, copper tube coils give high heat transfer in a compact footprint.
Precise Control
PID control holds temperature within ±1°C (±1.8°F). An electric valve regulates chilled water flow; optional pressure-independent control valves (EPIV) or electronic valves (EV) measure and control flow directly. RS-485 communication comes standard.
Reliable
Chilled water is a safe, simple cooling medium. Built-in alarms and diagnostics protect the unit, catch faults early and extend service life.
Easy to Maintain
Controls and safety devices sit in a compartment separate from the airflow, with all service from the front.
