GENERAL SPECIFICATIONS Description of the components The complete series of industrial chillers and heat pumps for use in hydronic systems includes 12 constructional sizes rang from 53.5 to 200 kW in the cooling mode. Main components: 1. Fans. These are the helical type with scythe-shaped blades to increase the efficiency and reduce the noise level. The fans are directly coupled to the single-phase motor by means of an external rotor. - Page 7 GENERAL SPECIFICATIONS 3. Compressors. They are the SCROLL type with orbiting coil equipped with built-in thermal protection and oil heater. The AS unit includes: a soundproofing jacket for the compressors, an acoustic cladding around the compartment where they are hou- sed, to reduce noise level, and reduced rotating speed of axial fans;...
