Features & Beneﬁts

The models featured here are specically designed for use with carbon dioxide (CO2) refrigeration systems, which are optimized for lifecycle climate performance (LCCP). Carbon dioxide refrigeration systems have zero ozone depletion potential and a very low global warming potential . The evaporators described in this technical guide are UL listed for the US and Canada and meet NSF standards.

LOW VELOCITY LOW PROFILE MEDIUM PROFILE CENTER MOUNT

CABINET

Air moves across the ceiling

Low air velocity helps to

maintain high humidities

and prevent product drying

and weight loss; low sound

makes a comfortable

working environment

Textured aluminum cabinet

for maximum durability

All electrical components factory wired to terminal board and identied, making it easy to eld wire the unit.

Minimal height of the low

prole series makes it ideal

for low ceiling coolers, allowing for maximum

headroom and more product

storage

Textured aluminum cabinet design features front access panels on each side for easy

access to electrical and

refrigeration components

Internal panels are “isolated” which provides for quiet unit operation

Heavy-duty design is ideal

for larger walk-in coolers and

freezers

Textured aluminum cabinet

for maximum durability

in both directions providing

even air distribution

throughout the cooler.

Compact, ceiling mount

design allows for shelving

and storage of product

around walls.

Heavy-guage grained

aluminum cabinet cleans

easily and looks attractive

Wire fan guards with PVC coating are standard and

provide added durability

Double drain pan eliminates

drain pan swelling and

tapered mounting provides

proper slope for condensate

drainage to one end of the

unit

– – 575 volt units available –

HEATERS AND COIL

Heater/fan control is factory set and wired

Coils are dehydrated and sealed at the factory

Sweat connections to reduce potential for leaks

GUARDS AND MOTORS

Featuring plastic guards and

a motor mount design that

is optimized to minimize

vibration

Energy-ecient EC motors are standard (Totally Enclosed)

Motors plug into wiring harness for easier servicing

Standard molded fan guards

provide excellent air throw

(optional wire fan guard for

diused air pattern)

DRAIN PAN

Optimized drain tting

position

Front hinged drain pan for

easy access

OPTIONS

Available in stainless steel cabinets and/or drain pan

Copper n or coil coating (available for air defrost only)

Wire fan guards with PVC

coating for durability

Double drain pan eliminates

drain pan swelling and

tapered mounting provides

proper slope for condensate

drainage to one end of the

unit
