Levitor II Air-Cooled Condenser
Benefits and Features
The LEVITOR system addresses refrigerant coil wear
and leaks due to vibration and thermal stress.
LEVITOR Coil Design Eliminates Refrigerant Tube Wear
Rooftop condensers have to operate in some of the toughest
conditions imaginable. Temperature extremes result in
constant expansion and contraction of refrigerant tubes as
fans cycle and loads vary.
The consequences are costly: rapid tube wear results in
leaks, system breakdown ­and loss of costly refrigerant.
Environmental concerns and spiraling cost of refrigerants have led to the
development of direct drive remote air-cooled condensers with the LEVITOR
coil support system. This innovative design uses dedicated stainless steel tubes
and a unique coil support system to isolate refrigerant tubes from the unit. Coil
support is transferred from the fins to the stainless tubes and truncated tube
plates which ride freely in “C” channels. Tubes expand and contract without
interference. The result, contact and friction wear are eliminated.
Quiet by Design
LEVITOR coil design does more than just eliminate tube wear.
Sound reduction is an added benefit. Unlike traditional air-cooled condensers,
fan and coil vibration are isolated from the cabinet, so it is not transmitted to
the unit frame and building supports.

Multi-fan sections compartmented to allow
individual fan cycling while preventing off-fan
“windmilling”. Large clean-out access doors
standard.

Levitor II Air-Cooled Condenser
Levitor Application
Locate Condensers no closer than their width from
walls or other condensers. Avoid locations near
exhaust fans, plumbing vents, flues, or chimneys.
Parallel Condensers should be the same models
resulting in the same refrigerant side pressure drops.
Compressor discharge lines should have equal
pressure drops to each condenser.
Summer Charge based on 25% of condenser volume
with 90˚F liquid. Multiply by 1.1 for R-407A.
Winter Charge based on 90% of condenser volume
with -20˚F liquid. Multiply by 1.08 for R-407A.
Receiver Capacity should be sized to store condenser
summer charge, plus the condenser low ambient
allowance, plus the evaporator charge, plus an
allowance for piping and heat reclaim coil charges.
Compressor Discharge lines should be sized to
minimize pressure drops and maintain oil return gas
velocities. Each connection should be looped to the
top of the condenser.
Gravity Liquid Drain Lines should drop from each
outlet as low as possible before headering or running
horizontally. Pitch downhill to receiver.
Off-Line Coil Sections will have refrigerant pressures
corresponding to the ambient. Check valves or
isolating valves should be installed in the liquid line
drains to prevent refrigerant migration and receiver
pressure loss.
See Installation and Operating instructions for piping, holdback, and speed control details.

NOTE FOR TABLES TO THE LEFT:
*** Indicates Rows and FPI. The tables show the

NOTE: Capacity ratings are based on midpoint condensing temperature, 95˚F entering air temperature and 0˚F sub-cooling.
The temperature difference is between the midpoint condensing temp. and the entering air temp. to the condenser.
Units compliant with Title 24 are programmed to run their motors at a lessened top speed, significantly reducing their energy usage with a minimal impact on capacity.
At full speed, each motor consumes 1383 watts. However, as these motors are continuously variable speed they will use significantly less energy during standard operation.
See Corrections Factor Table on page 3. See Electrical Motor Amp Data Table on page 6.

Low Ambient Controls (Head Pressure Control System)
Piping Schematic for Winter Control
n
ead Pressure Control for systems with air-cooled condenser is accomplished with two
H
pressure regulating valves designed specifically for this type of application. When low ambient
conditions are encountered during winter operation on air-cooled systems with a resultant
drop in condensing pressure, the Head Pressure Control’s purpose is to hold back enough of
the condenser liquid refrigerant so that some of the condenser surface is rendered inactive.
This reduction of active condensing surface results in a rise in the condensing pressure and
sufficient liquid line pressure for normal system operation.
