Water-defrost unit cooler

Water-defrost unit coolers suit cold rooms where electric defrosting is unsuitable or rapid defrosting is required. DL, DD and DJ series suit room temperatures around 0°C, −18°C and −25°C respectively.

Features

• High-quality corrosion-resistant stainless steel casing.
• Staggered coils with mechanically expanded copper tubes ensure close contact with aluminum fins for effective heat transfer.
• Water defrosting provides fast, effective defrosting with low energy consumption.
• Please contact us for special applications.
