The most important features of the range of industrial dual-flow air coolers offered by Stefani are extremely compact units combined with superior performance, thus satisfying the most demanding applications thanks to the wide variety of options and accessories.
The diameters available for air cooler fans are 300 mm, 350 mm (with 4 and 6 poles) and 450 mm (double speed), while power ranges from 0.8 to 36 kW.
With 144 products marketed and besides the range for HFC refrigerants (SHDC), Stefani has designed units for applications with CO2 fluid (SBDC), glycoled water (SGDC) and ammonia (SADC) through stainless steel tubing.
Due to their compact size, these industrial double-flow air coolers are suitable for coldrooms with reduced height intended for the conservation of frozen fresh products and where the presence of personnel for the processing of meat, fish and dairy products is required.

• For processing rooms, fin spacing = 4 mm
