DORIN Semi-Hermetic condensing units AU (UA) Air-Cooled

Condensing units AU series are the standard ones, that can be used in all applications.

All condensing units can operate with R449A/448A, R134a, R404A, R507 , R407F/A , R407C, R513A, R450A, R452A within the limits inducated in manufacturer specifications.

Condensing units are fitted with air-cooled condenser with copper tube and new design alluminium fins, high efficiency electric motor-fan equipped with safety grill, liquid receiver with safety valve and anti-vibration damper on discharge piping (when icluded), gas and liquid piping, steel frame.

Noise level

To cope with the always more stringent requirements, DORIN select models of motorfans with high performances and low noise emissions, coupled with very silent compressor design.

Lubricants

All condensing units are equipped with compressors charged with POE with viscosity of 32 cst at 40⁰C suitable for HFC.

Condensers

New design of condensers coupled with new motorfans ensure very high mass flows and low noise emissions. 

Fans

The AU air condensing units are fitted with motor fans with a new, innovative hybrid blade construction; this motor fans are quieter, more efficient and longer lasting. Blades are made of a corrosion resistant aluminium alloy supportive structure, a special fibre-reinforced plastic is then covering the underneath layer (Hy-Blade fans); this innovative combinations of materials brings remarkable reduction in weight. All motorfans are fitted with motor 230V/1/50-60Hz complete with capacitors and they are suitable for the use of electronic frequency regulators. All motorfans are fitted with an internal protection against overtemperature.
