Standard unit cooler

D Series unit coolers are designed for cold rooms using fluorocarbon refrigerant systems. DL units suit fresh storage around 0°C, DD units suit frozen storage around −18°C, and DJ units suit blast freezing below −25°C.

Features

• Designed for fresh, frozen and chilled storage, with efficient heat exchange and low operating costs.
• High-quality steel casing with a corrosion-resistant powder-coated finish.
• Staggered coils with mechanically expanded copper tubes ensure close contact with aluminum fins for effective heat transfer.
• Stainless steel electric heaters are distributed throughout the coil for effective defrosting and long service life.
• The fan-to-fin spacing exceeds one-third of the fan diameter to maintain effective airflow.
• Fin spacings of 4.5, 7 and 9 mm are available to suit room size and use. Variable fin-spacing designs can be supplied for special requirements.
• Please contact us for special applications.
