Model BTOTwin Flow Reach In Unit Cooler
APPLICATION
Twin flow unit coolers are ideal for temperatures of 35°F and
higher. Box temperatures are kept more constant throughout
and fresh products last longer. Seven sizes are available with
BTUH from 900 to 5,500 at 10° TD. Larger BTO sizes are
suitable for large reach-in and small step-in or walk-in
coolers.
FEATURES
•Compact two-way design with medium velocity air flow.
•Mounts flush to the ceiling and draws air in through the fan
and discharges out both sides.
•Air pattern reduces air loss when doors are opened and the
medium velocity reduces product drying.
•Textured aluminum cabinet.
•Stainless steel fasteners.
•Molded Lexan® fan guards - safety approved.
• Drain pan and fan panel is easily removed for installation
and servicing.
•Coils are copper tube with aluminum fins.
•Expansion valve mounts inside the cabinet.
•Internal junction box is provided for electrical connection.
•Motors are thermally protected and permanently lubricated.
• UL listed for the United States and Canada; UL classified to
NSF standards.
