options on many of our Reach-In products. These coatings provide superior protection in most common
refrigeration environments. If you have a question about a specic application, please contact your
Bohn representative.

E Solutions™ branded products and options are designed to exceed current energy
and environmental standards. We have made a conscious commitment to developing
environmentally innovative products that allow our customers to make energy
ecient, eco-conscious choices. Products included in the E Solutions portfolio reduce
costs, improve bottom lines, and enhance both equipment performance and service

MODEL C

High Profile Reach-In Unit Cooler

Features

• Textured aluminum cabinet

• Molded Lexan® guard

• Drain tting at 45-degree angle so drain can be run
through bottom or back of refrigerator

• Aluminum hangers automatically space the unit to the
correct distance from the back wall

• Stainless steel screws prevent rust streaks

• Room for expansion valve inside the unit

• Knockouts in sides and top plus openings in rear provide
maximum exibility for electrical connection

• Expansion valve can be mounted inside the cabinet

• Full collar aluminum ns on expanded copper tubes

• Internal junction box with pigtail leads for
electrical connection

• Motors are thermally protected and
permanently lubricated

• All models UL listed for US and Canada

• UL classied to NSF standards

• Optional coated coil available (Model CK) for
enhanced protection in corrosive environments

• Sweat inlet connection standard to reduce leaks

(are connection available as a ship loose option)

Application

Model C is the ideal unit for refrigerated reach-ins. It mounts to

the top of the refrigerator and discharges cold air against the back
wall. With this air ow pattern, the air is not blasted on the product
but is diused along the back wall and then gently drawn across
the product as it returns to the unit. Thus uniform temperatures
are maintained throughout the refrigerator. In addition, door
sweating and refrigeration loss due to door opening is greatly
reduced because the air is not discharged against the doors.

Application
Models BB are compact, wall-mounted units whose low height makes them

ideal for undercounter reach-in or drawer-type xtures. The unit draws air in at
the bottom and discharges out the front. An optional air deector is included and
can be mounted over the center of the fan to direct air up and out. The deector
can be eld-formed to direct the air where needed, usually onto drop-in trays of
condiments in salad bar or sandwich preparation xtures. An S-type mounting
angle is included to position the unit 3/4" o the wall which gives optimum air
circulation and performance.

The BBM (medium temperature) model is designed for 35° to 40°F xture
temperature with o-cycle defrost. The unit is designed to operate at 10° to 17°
TD and 16 hours per day compressor run time.

The BBL (low temperature) model is designed for 0° to -10°F xture temperature,
and has automatic electric defrost. The unit is designed to operate at 8° to 15° TD
with 18 hours per day compressor runtime. The BBL has an incoloy sheath heater
embedded in the bottom n surface for ecient and fast defrosting. A drain pan
heater is included to ensure complete condensate drainage. A disc-type sealed
defrost termination/fan delay control is mounted and wired. Field connectors
are located at the terminal board.

Model RAMK

under-counter drawer type refrigerators and salad bars. The
unit is suitable for mounting behind a mullion or on a wall. An
up ow air pattern is used with air drawn in at the bottom and
discharged out the top. This provides optimum temperature for
drop in trays on salad bars or prep tables. It also keeps drawer
stored product in premium condition.

An adjustable and detachable air deector/splash protector
is included. The deector can be adjusted to direct the air up
and out at a 45-degree angle. This feature provides excellent
air distribution over drop in trays or containers. Food in the
trays and containers stays colder, lasts longer, and retains the
desired appearance. The deector can be adjusted to distribute
air out both sides when used as a mullion unit.

MODEL BTO

Twin Flow Reach-In Unit Cooler

Features

• Compact two-way design with medium velocity air ow

• Mounts ush 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

• Drain pan and fan panel is easily removed for
installation and servicing

• Optional coated coil available (Model BTOK) for enhanced
protection in corrosive environments

• Coils are constructed of copper tubing with aluminum ns

• Expansion valve can be mounted inside the cabinet

• Internal junction box is provided for electrical connection

•

Motors are thermally protected and permanently lubricated

• All models are UL listed for the US and Canada

• UL classied to NSF standards

• Sweat inlet connection to reduce leaks

(are connection available as a ship loose option)

Application

Model BTO is 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.
