# ACIH: specifications and models

ACIH is an industrial compressed air system for hospital buildings, supplied independently of medical air because, as its datasheet notes, hospital standards prohibit using medicinal air for industrial purposes.

It supplies equipment such as autoclaves, drying processes and pneumatic valves, using rotary screw compressors, air treatment units and tanks.

## Key facts from the datasheet

- The datasheet states ACIH was developed because hospital standards prohibit using medicinal air for industrial purposes.
- ACIH resembles the ISO 7396-1 requirements for redundancy and for command, control and alarm systems.
- Air treatment keeps its filtration capacity over 6,000 to 10,000 hours of continuous service.
- Tanks are vertical with capacities of 100 to 3,000 litres.
- A condensate treatment unit removes oil so condensate can go to the sanitary network.
- On request ACIH can be built with totally oil-free compressors.
- Control options are analogue, digital and QuAir with digital console and PC communication.
- The compressors can work at room temperature of up to 50°C.
- The centralised management controller can control up to 12 compressors.
- The controller communicates over RS 485 Modbus RTU.
- The compressor allows a standard environmental temperature of 45 °C.
- The suction filter has 99% efficiency with a porosity of 1 µm.
