Optima INV DXA 80V2A4 + 2xAMAE15
The OPTIMA product family from Airsys was specially developed for use in small, medium and large data centers as well as for process and clean room applications. OPTIMA devices combine precise temperature and humidity control with outstanding reliability.
OPTIMA INV-DXA units have EC fans and inverter compressors with air-cooled external condensers for optimized energy efficiency.

Functional scheme
Optima.INV-DXA
Direct expansion device, air-cooled (DXA)
Room heat is transferred to the circulating refrigerant in the indoor unit at the evaporator and released to the environment outside at the air-cooled condenser.
Air-cooled DX system (DXA) includes expansion valve, evaporator register, scroll compressor and refrigerant line.
Direct expansion device, air-cooled; with indirect free cooling (FC.DXA)
The FC.DXA device is a two-circuit system that combines DXA heat emission with indirect free cooling. The respective cooling circuits are independent of one another.
When cooling is requested and the difference between the indoor and ambient temperatures is sufficient, the device works in FC mode to provide indirect free cooling by dissipating heat via a dry cooler. Mechanical cooling is only switched on if the free cooling capacity is insufficient to cover the cooling load.
Direct expansion device, air-cooled; with additional cooling register (DC.DXA)
The FC.DXA and DC.DXA series are largely identical. The additional register in the indoor unit becomes one here
external, on-site cold water network supplied. This series therefore also offers two independent cooling systems (air-cooled direct evaporation, cold water cooling), the use is mainly based on redundancy considerations.
