Expanded (Locked) Auxiliary Tubes:
These tubes support the coil with ns and refrigerant
carrying tubes. They do not carry refrigerant and are
tightly tted on end supports and center supports.
Free Floating Circuited Coil Tubes:
These tubes carry refrigerant and never touch
and sheet metal (end supports and center
supports).
Air Discharge Condensing Units
All BLV, BDVS, JLD and JDDS
units include a limited
Five Year Warranty
against condenser leaks at tube sheets
and center supports.
All condensers use the Floating Tube™ coil design to eliminate refrigerant leaks at the tube
sheets. Additional tubes are added to the condenser coil. These tubes are expanded into the
aluminum ns and condenser tube sheets. These anchor tubes support the weight of the coil,
but are not a part of the refrigerant circuit.
The tubes in the refrigerant circuit are expanded into the ns, but “oat” through oversized
holes in the tube sheets. Tube sheet leaks are virtually eliminated, since the tubes which carry
refrigerant never come in contact with the tube sheet.

• Complete factory installation, wiring and testing which
saves time and money!
• Simplied eld electrical connections and 24 volt wiring
between condensing and evaporator coil.
• Preset factory superheat allowing the system to run more
eciently and reducing future adjustments.
• Monitors and controls box temperature,
evaporator superheat, system status and

• Monitor and make system changes
remotely via modem and exclusive

• Data logging capabilities with Smart

Beacon II™ Smart Controller is an optional system monitoring
and programming control device. It allows for adjustments to be made
at the push of a button from a conveniently mounted location. Beacon

II
Smart Controller also allows you to monitor
and make changes to the refrigeration system
via modem connection from anywhere in the
world. One Smart Controller can program and
control up to four condensing units with up to
four evaporators on each system. That’s more
control in your hands!
The patented Beacon II
Smart Controllers is uniquely designed to predict frost accumulation
and initiates defrosts only when they are needed. It also initiates
defrosts to react to operation anomalies, like product deliveries and
product pull-down. Typical electric defrost systems have 4 defrosts per
day. Using the Smart Defrost system can reduce the number of defrosts
to 0, 1, or 2 per day. That’s a 75% reduction on average. This greatly
reduces the amount of energy used and
in turn reduces operating costs.

The Need For Head Pressure Control
Refrigeration condensing units must eciently perform at varying
ambient conditions. A properly sized unit will adequately perform
at even the highest summer ambient temperatures. However, in
situations where the system must operate the majority of the time at
less than design temperature, a means of providing adequate head
pressure for refrigerant ow is desirable. The BLV & JLD units have an
adjustable Limitizer® method of head pressure control.
The Bohn Limitizer® System
The Limitizer® system is a factory assembled system utilizing a Limitizer®
control to maintain a constant head pressure at the air cooled
condensing unit during all climatic conditions when the ambient
temperature drops below 75°F (typical).
When the ambient is above 75°F, the condenser pressure is above
the Limitizer® valve setting and therefore, the valve remains in the full
open position.
As the temperature drops below 75°F, the pressure at the condenser
also drops below the setting of the Limitizer® valve. The Limitizer®
valve, sensing the reduction in condensing pressure, modulates
toward the closed position, thus restricting the ow of liquid from the
condenser. The liquid backs up into the condenser and oods a portion
of the tubes, thus reducing the overall capacity of the condenser. The
Limitizer® valve will continue to ood the condenser until the pressure
setting has been reached, thus providing proper head pressure at all
ambient temperatures.
While the condenser oods, a second line pressurizes the receiver
through another valve. Therefore, the refrigerant flow from the
condenser to the receiver modulates with conditions. However, the
bypass from the discharge line maintains a minimum receiver pressure.
These valves are adjustable and the minimum receiver pressure may
be reset higher or lower depending upon application situations of a
particular job. The Limitizer® system uses this two-valve, adjustable
design.
Beacon II™ Smart II Software makes it easy to adjust and
monitor one or more refrigeration systems as well as capture minute
by minute system conditions. This Windows-based software allows
you to connect to the Beacon II
the world to monitor the systems, make adjustments and log minute
by minute system conditions.
This data logging capability
is critical in the food service
industry.
