Model BTO
Twin 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.
• Optional corrosion-resistant coated coil available (Model
BTOK) for optimum protection in corrosive environments.
