Features & Benets
Bohn introduces it’s latest line of heavy duty large unit coolers for warehouse
cooler/freezer applications. With a wider capacity range and the patentedThermo-
Flex coil design, these large unit coolers provide ecient, reliable operation. Bohn
has designed many features and options into this product line to give you a superior
heavy duty evaporator.
Features
• Mill nish aluminum provides an
attractive design and structurally
sound cabinet
• Thermo-Flex (with ve-year limited
warranty) is innovative,
eliminates leaks, and reduces risk of
refrigerant loss
• 850 rpm motors are quiet
and reliable
• Liquid line solenoid wiring harness
for faster installation
• Suction Schrader tting for easier
suction temperature measurement
• Hinged drain pan and access panels for
easy servicing
• Captive fasteners on access panels for
easy servicing — no fumbling with
loose bolts and nuts
• Adjustable defrost control can be
customized per application
• Long air throw is ideal for large
warehouse and industrial applications
• Standardized terminal board for easier
eld wiring
• Complete hot gas defrost model
oering meets more applications
Options
• High CFM motor and fan combinations
(208-230/3/60 and 460/3/60)
• Totally enclosed motors (208-230/3/60
and 460/3/60)
• Low temperature motors for blast cooling
and freezing (for room temps -31°F to -50°F)
• Long air throw collars for large warehouse
and industrial applications
• More factory mounted features for easier
eld installation (consult factory)
• Insulated drain pan
Innovative
Thermo-Flex™
Coil Design
Bohn’s innovative coil design utilizes a
unique approach to coil expansion that
virtually eliminates the possibility of
leaks at tube sheets and coil supports.
The Thermo-Flex™ coil design for the
unitcooler*allowsthecoilto“ex”during
periods of defrost resulting in expansion
of the coil surface. By eliminating the
possibility of wear at critical stress areas,
the integrity and longevity of the unit
are dramatically increased.The result is a
product which greatly enhances overall
system reliability and reduces risk of
costly refrigerant loss.
Bohn offers a five-year limited
guarantee against leaks at tube
sheets and center supports for all
medium prole unit coolers.
