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).

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.

All units include a limited

Five Year Warranty

against condenser leaks at tube sheets and

center supports.

is necessary. To begin, preset defrost times using the

Beacon II™ Smart Controller. At each scheduled defrost

time, Smart Defrost checks system performance to see

if a defrost is necessary. If not, it simply does not defrost,

waiting until the next scheduled defrost time.

Options

Refrigeration condensing units must efficiently

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 CDV & CDD

units have an adjustable method of head pressure

control.

This system provides year round control of refrigerant

head pressure without the use of special refrigerant

expansion valves. As the ambient temperature falls,

the reciever pressure is allowed to fall to a minimum

of 75°F saturated condensing pressure. The reduced

discharge pressure at the compressor increases the

compressor capacity and lowers the input watts

from the compressor motor. The system also uses

the reduced ambient temperature to subcool the

liquid refrigerant in the condenser. This subcooled

liquid also increases system capacity. As a general

rule, every one degree of subcooling results in 0.50%

increase in system capacity. Together these result

in greater eciency, greater capacity, and reduced

run time.

Benets:

• Automatic year-round control of refrigerant head

pressure without the use of special expansion

valves.

• Energy savings in mild ambient conditions due

to reduced compressor discharge pressure and

refrigerant subcooling

• Provides easy restart during low ambient

conditions.

Operation

As the ambient temperature falls, the system

condensing pressure is also reduced. This pressure

is maintained by a regulator (ORI-6-65/225) at the

condenser drain. At approximately 75°F saturated

condensing pressure the regulator restricts the flow

of liquid refrigerant from the condenser causing the

condenser to flood. This condenser flooding allows

the liquid refrigerant in the condenser to become

subcooled by the ambient air flowing through the

condenser. As the regulator continues to flood the

condenser, a pressure differential will be established

between the receiver and the compressor discharge.

At a predescribed differential, a second valve (ORD-

4) will open and allow discharge gas from the

compressor to bypass the condenser and flow into

the top of the receiver. This gas is used to pressurize

the receiver. These valves are adjustable and the

minimum receiver pressure may be reset higher or

lower depending upon application situations of a

particular job.

Subcooled liquid is further enhanced by the routing

of liquid from the receiver liquid line outlet to the

condenser before leaving the condensing unit.

Bitzer Quiet!!!

Bitzer compressors are famous for their low sound

levels. We change capacities within a frame size by

changing our bore diameters rather than the length

of the piston strokes. This gives our compressors an

unsurpassed balance and precision that translates

to low decibels. In addition, Bitzer compressors

have a muer built into each head (see photo) that

eliminates pulsations and reduces the sound levels

even further.

Bitzer Compressors

Features and Benets

Octagon® 4C Models

Bitzer Octagon 4C Models are rated from 3 to 20 HP. This rugged, compact

series utilizes wear resistant drive gear with PTFE coated bearings for especially

low friction, aluminum pistons of optimized geometry, connecting rods with

eccentric straps and generously dimensioned bearing surfaces. Bitzer’s centrifugal

lubrication system eliminates the need for an oil pump and provides optimum oil

supply to the compressor even under extreme operating conditions.

Centrifugal Lubrication

The centrifugal lubrication design employs a solid metal disc

mounted to the crankshaft (see cut-away) that distributes

oil into a reservoir at the end of the shaft. The oil then ows

through the shaft to the bearing surfaces.

Bitzer oers an optional Optical Oil Sensor (See OLC-K1 photo

below) that mounts to the outer cover of the compressor

and monitors oil level by means of an infrared light.

OLC-K1 Operating Principle

The OLC-K1 sensing device shines an infrared light into

the oil reservoir. If oil is present, the light is absorbed

and the compressor runs normally. If no oil is present,

the light reects on the sensor, and the compressor

shuts o.

Bitzer 4B & 6B Models

Bitzer 4B through 6B Models are rated from 13 to 50

HP. This series features surface hardened crank shafts,

low friction bearings, aluminum pistons, hard chrome

plated piston rings and special wrist pin bearings.

The 4B & 6B models have a sealed main bearing and

generously sized oil pump. Our patented oil return

system ensures complete lubrication while reducing oil

circulation into the system. Ecient capacity control

is provided by unloader banks that can signicantly

reduce energy consumption.
