Bulletin 306.0D
August 2004
(Replaces 306.0C • 3/04)

Low Profile Unit Coolers

Model ADT - Air Defrost • Model LET/LLE - Electric Defrost • Model HGT - Hot Gas Defrost

Front access to refrigeration
components. Hanger bars are now
located on the inside of the cabinet

view from bottom

Motor harness and solenoid harness are easier to access from
the bottom of the coil. The drain pan heater is located on
the bottom of the coil, which allows the drain pan to be
removed without the removal of the heater. The drain pan
heater also extends into the end panels for more heat in the
side panel cavities.

-2-

Improved plastic blue guard
design (wire guard available
as an option).

Improved drain pan design. Drain pan hole
is now located to the back of the drain pan
and is larger in diameter 3/4” ID (3/4” MPT
drain line fitting).

Front facing electric board for
easy access. Optimized space
in end panels.

The standard design for the new Bohn Low Profile Evaporators will incorporate an efficient hot gas loop
in the drain pan. Utilizing a hot gas loop is ideal for hot gas defrost applications where high temperature
gas can be maintained to defrost both the evaporator drain pan and coil.
For applications where cooler (lower) temperature hot gas is used for defrosting, Bohn offers optional
electric heater elements in the drain pan to ensure quick and efficient defrost of the drain pan allowing
condensate to drain quickly, saving the hot gas for efficient evaporator coil defrost.
If the optional electric heating element drain pan is preferred, please specify when ordering, there is no
additional charge.

Recommendation is that both check valve kits are ordered:
(For hot gas models with the hot gas loop drain pan ONLY)
Note: The drain pan check valve kit can be ordered as an independent item. But the suction line check valve kit
must be ordered with the drain pan check valve kit in order to complete the piping.
Note: When using the HOT GAS units on 0°F applications and below, an insulated drain pan is required.

The Hot Gas unit coolers can be used in reverse cycle hot gas defrost systems using multiple evaporators
connected to one condensing unit. Generally, not more than one-third of the system defrosts at one time.
During the reverse cycle defrost, the reversing valve; located in the compressor discharge line, diverts hot gas
through the suction line to the evaporator.
See piping view in Figure 1. The suction line
check valve directs the hot gas through the
drain pan loop which prevents condensate
in the pan from freezing. The hot gas exits
the loop at the pan loop outlet header and
enters the evaporator through the check
valve assembly. As the hot gas defrosts the
coil, heat is removed from the hot gas and
eventually it condenses into a liquid and
exits the coil at the distributor sideport.
The liquid then flows through the check
valve of the thermostatic expansion valve
bypass assembly, around the thermostatic
expansion valve, and into the system liquid
line. The liquid refrigerant then feeds
other evaporators on the cooling cycle,
evaporates, and returns to the compressor through their suction lines.

Reverse Cycle Kits

Hot Gas Reverse Cycle Kits (cont.)
In the refrigeration cycle, the thermostatic expansion
valve bypass assembly check valve only allows
refrigerant flow through the thermostatic expansion
valve and into the evaporator coil. As the refrigerant
vapor exits the coil at the suction line, the check valve
of the drain pan loop check valve assembly prevents the
refrigerant vapor flow through the drain pan loop.

Figure 2. Typical Liquid Line Bypass Kit
(Shown assembled and modified for heat exchanger)

Factory engineered assemblies (kits) are available for
both ship loose and factory installed at an additional
cost to complete the reverse cycle piping and
components. The suction line check valve assembly
includes the suction line check valve and the piping for
both the suction line and the connection to the drain
pan loop inlet header. In order for the suction line
check valve assembly to be mounted, the drain pan loop
check valve assembly must be used. The drain pan loop
check valve assembly includes the check valve, suction
line tee and a bent pipe. The thermostatic expansion
valve bypass assembly option includes the check valve,
tee and necessary piping. In order for the thermostatic
expansion valve bypass assembly option to be complete,
a thermostatic expansion valve must be selected by the sales engineer. The thermostatic expansion valve bypass
assembly option is dependent on the body style of the thermostatic expansion valves which includes the Sporlan
SQE, SBF, EG and the Alco HFESC body styles. The factory installed thermostatic expansion valve bypass assembly
option must have the thermostatic expansion valve selection included on the order for the Hot Gas unit cooler.
To increase the efficiency, higher performance and greater system protection, a heat exchanger may be beneficial
to the system. In order to use a heat exchanger, the thermostatic expansion valve bypass assembly option
must be modified. See the piping view in Figure 2. The modification includes rerouting the pipe from the
thermostatic expansion valve bypass check valve to the inlet connection of the liquid line to the heat exchanger.
A pipe needs to be routed from the liquid line outlet connection of the heat exchanger to the inlet connection
of the thermostatic expansion valve.
The electrical control option includes an adjustable defrost termination and fan delay control (DTFD) which is
standard. For an additional cost, an optional (2) control electrical system is available with one adjustable control
for defrost termination (DT) and one fixed control for the fan delay (FD). For both the DTFD and DT adjustable
controls, the remote bulb position is with the bulb strapped to the piping of the thermostatic expansion valve
bypass assembly option between the distributor sideport and the check valve. When the thermostatic expansion
valve bypass assembly is ship loose, the installer will need to position the remote bulb. When the thermostatic
expansion valve bypass assembly is factory installed, the remote bulb should already be properly installed.

Hot Gas Defrost
Hot Gas3-Pipe
Defrost
The Hot Gas defrost unit coolers conforms to
the standard 3-pipe hot gas system using a
check valve assembly, an electrical control to
terminate the defrost, and a hot gas solenoid
valve. The check valve assembly transports
the hot gas between the drain pan loop and
the sideport distributor of the coil. The check
valve assembly kit is available for ship loose or
factory installed for an additional cost. The
electrical control option includes an adjustable defrost termination and fan delay control
(DTFD) which is standard. An optional (2)
control electrical system is available with one
adjustable control for defrost termination
(DT) and one fixed control for the fan delay
(FD) for an additional cost. For both the
DTFD and DT adjustable controls, the remote
bulb position is with the bulb strapped to
the suction line to insure a complete defrost.
The remote bulb is positioned by the installer.
The hot gas solenoid valve must be ordered
separately and will be ship loose. The termostatic expansion valve could be ordered separately and ship loose or
the thermostatic expansion valve could be factory installed with a liquid line for an additional cost. The liquid line
is designed for the body styles of the Sporlan SQE, SBF, EG and the Alco HFESC thermostatic expansion valves. The
thermostatic expansion valve needs to be selected by the sales engineer. In a typical 3-pipe, multiple evaporator
system, the compressor discharge defrosts the evaporator. The liquid/vapor mixture of refrigerant after defrost,
however, returns to the common suction line of the system. In order to provide sufficient re-evaporation of the
liquid vapor mixture and sufficient heat for defrost, no more than one-third of the system should be defrosted at
one time. Some means of control in the 3-pipe hot gas system should be supplied to regulate the large amount of
liquid returning to the compressor, Refrigerant slugging can otherwise damage the compressor.
