2 Product Overview > The NK range is designed for industrial refrigeration, storage or deep-freezing applications > The NK version H (high efficiency) is ideal for the storage of packed products > Economical choice, wide range of options for specific Heavy Duty industrial applications. Range offers fin spacing distances: 4, 6, 9 mm (6, 4 or 3 FPI) Description Casing The casing is made of pre-painted, galvanised steel offering a high resistance to corrosion and impact damage An internal aluminium drain pan limits the effects of condensation under the main drain pan during the defrost process The NK unit coolers are delivered in mounting position in reinforced crates Ventilation 2 fan types are used for the NK range: Ø 630 mm 4/6 pole (1,500/1,000 rpm) - Ø 800 mm 6/8 pole (1,000/750 rpm) Selection of a unit cooler with various fan number/diameter combinations offering the dimensional and air throw characteristics best adapted to the size of the cold room Selections should be confirmed by your Heatcraft Technical Specialist ( ) Coil The finned coils of the NK range are designed with aluminium fins spaced at 4, 6, or 9 mm, crimped onto copper tubes High-efficiency H type fins for an economical solution. This type of fin is particularly suitable for the storage of packed products. The reduced size of the heat-exchanger also enables fast defrosting The galvanised steel side panels and drain pan are hinge mounted for easy access, maintenance and cleaning.
