KTW Two-Way
Unit Coolers

High, Medium and Low Temperature
Applications -10°F (-23.3 °C) Room
and above
Air or Electric Defrost Models

Electrical Power:115/1/60,
208-230/1/60, 200-220/1/50

• Low height compact size maximizes useable
storage space

• Dual refrigeration coils and two-way air
distribution reduces air velocities to minimize
product dehydration.

KeepRite
Two-Way Unit Cooler

o

Nominal Capacity @ 10

9 = 900 Btuh
Air Defrost (AD) rated at 20 °F Evap. T emp.
Electric Defrost (ED) rated at -20°F Evap. T emp.

Type of Defrost

AD = Air Defrost
ED = Electric Defrost

Electrical Designation

S1 = 115/1/60
S2 = 208-230/1/60
S6 = 200-220/1/50

F TD

• Air enters through fan and discharges two ways
out of each coil side.

• NEW rugged heavy duty motor mount reduces
vibration and noise.

• Electric defrost models include factory installed
defrost termination and fan delay thermostat.

• NSF approved “flush to ceiling mount”
