Dual-discharge unit cooler

HSD dual-discharge unit coolers suit processing areas with specific airflow, airspeed and noise requirements. Air is drawn from below and discharged gently from both sides. They suit room temperatures of 5–12°C; electric defrost heaters are required below 5°C.

Features

• A compact, lightweight design with smooth operation improves usable space in cold rooms and processing areas.
• Corrosion-resistant stainless steel casing with a clean appearance.
• Staggered coils with mechanically expanded copper tubes ensure close contact with aluminum fins for effective heat transfer.
• Each dual-discharge unit cooler undergoes a 2.5 MPa leak test and internal cleaning.
• External-rotor motors with Ø400 mm fans; two to four fans are available for gentle, low-noise airflow from both sides.
• Two drain pans discharge condensate through separate drain pipes.
• Please contact us for special applications.
