Product Overview
N Series outdoor air cooled condensing units are specifically designed to meet the demands of multiple load applications required for commercial and industrial duty refrigeration applications. N Series condensing units are made to operate in adverse conditions and meet the needs of each customer with minimal changes to the basic design. Applications ranging from low temperature product storage, produce ripening, or medium temperature product storage can be readily supported by the N Series condensing units. These units are designed to operate in high and low ambient conditions.
N Series condensing units utilize Bitzer™ compressors, which are famous for their low sound levels. Bitzer™ changes capacities within a frame size by changing their bore diameters rather than the length of the piston strokes. This gives Bitzer™compressors an unsurpassed balance and precision that translates to low decibels. In addition, Bitzer™ compressors have a muffler built into each head that eliminates pulsations and reduces the sound levels even further.
Bitzer’s™ centrifugal lubrication design employs a solid metal disc mounted to the crankshaft that distributes oil into a reservoir at the end of the shaft. The oil then flows through the shaft to the bearing surfaces.
N Series condensing units come completely pre-piped and wired to reduce field installation costs and additional labor before installation. These units also utilize a unique horizontal condenser and coil design and high volume condenser fans. Each unit is provided with a separate sub-cooling circuit to maximize unit performance. The N Series condensing unit is suitable for mounting at ground or rooftop levels.
N Series condensing units can be matched with Century Refrigeration’s FV Series, FH Series, BALV Series, A Series medium profile unit coolers, BOC Series large profile unit coolers, PFE Blast Cooler/Freezer unit coolers, WIBR Series unit coolers, and XBOC Series unit coolers.
