LEVITOR II AIR COOLED CONDENSER 1Specifications subject to change without notice.

Benefits and Features

Low Sound Quietor Fann The “swept-wing” blade design offers lower noise levels atthe same fan speed. For example, the QUIETOR fan bladeon a 575-rpm motor will be much quieter (8 dBA) than theold 575-rpm fan.

n Lower noise condensers can translate into savings for yourcustomer by minimizing the need of costly noise barriers.

n Quietor fan not available on 18” models.

LEVITOR Coil Design Eliminates Refrigerant Tube Wear

Environmental concerns and spiraling cost of refrigerants have led tothe development of direct drive remote air-cooled condensers with theLEVITOR coil support system. This innovative design uses dedicated

stainless steel tubes and a unique coil support system to isolaterefrigerant tubes from the unit. Coil support is transferred from the finsto 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. Soundreduction is an added benefit. Unlike traditional air-cooled condensers,

fan and coil vibration are isolated from the cabinet, so it is nottransmitted to the unit frame and building supports.

The LEVITOR system addresses refrigerant coil wear and leaks due to vibration and thermal stress.

Rooftop condensers have to operate in some of thetoughest conditions imaginable. Temperature extremesresult in constant expansion and contraction of refrigeranttubes as fans cycle and loads vary.

The consequences are costly: rapid tube wear results inleaks, system breakdown and loss of costly refrigerant.

System Selection

THR Total Heat of Rejectionn Condenser total heat of rejection (BTU/h) is the sum of the evaporator refrigeration effect and the heat of compression which varies with compressor type and operating conditions.

THR Calculation Methodn THR = Open Reciprocating Compressor Capacity (BTU/h) + (2545 x BHP)

n THR = Suction Gas Cooled Hermetic Reciprocating Compressor Capacity (BTU/h) + (3413 x kW)

THR Estimated Methodn THR may be estimated by multiplying the rated compressor BTU/h capacity by the compressor operating condition factor shown in Table 1 or 2. Multiply result by altitude factor when applicable.

Multi-Circuit Selectionn Condenser coils may be divided into several individual refrigeration circuits or systems; each sized for a specific refrigerant,THR capacity and TD. Systems are tagged for identification from left to right; facing the connection end. Avoid locatinghigh TD sections next to low TD sections. Add excess circuits to low TD sections next to High TD sections. Add excesscircuits to outboard sections. Thermal Fantrol fan cycling is recommended with multi-circuited condensers.

Selectionn LAVA-15310 Rated at THR of 459.1 MBH with R-22 at 15°F TD. LAVA-15310 Unit lists 34 Circuits.

n Sample Calculation: THR Req’d./Circuit = 434984 ÷ 34 = 12784. LAVA-15310 = 459100 ÷ 34 = 13503 (Available THR/Circuit).

n Circuits Req’d. = Select THR ÷ THR/Circuit. Example: 57648 ÷ 13503 = 4.3 Circuits.

n Assign Number of Circuits System and System Number Left to Right. Actual TD = (Circuits Req’d ÷ Assign Circuits) x Design TD.Example: 4.3 ÷ 4 x 15 = 16.1.

Levitor Application

Locate Condensers no closer than their width from wallsor other condensers. Avoid locations near exhaust fans,plumbing vents, flues or chimneys.

Parallel Condensers should be the same models resultingin the same refrigerant side pressure drops. Compressordischarge lines should have equal pressure drops to eachcondenser.

Condenser Charge will approximate 30% of themaximum flooding charge listed under “Specifications” forsummer design conditions. Low ambient head pressurecontrols require an additional charge, which is difficult topredict with fan cycling and is maximized with holdback.

Receiver Capacity should be sized to store condensersummer charge, plus the condenser low ambientallowance, plus the evaporator charge, plus an allowancefor piping and heat reclaim coil charges.

Compressor Discharge lines should be sized to minimizepressure drops and maintain oil return gas velocities. Eachconnection 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 runninghorizontally. Pitch downhill to receiver.

Off-Line Coil Sections will have refrigerant pressurescorresponding to the ambient. Check valves or isolatingvalves should be installed in the liquid line drains toprevent refrigerant migration and receiver pressure loss.

Liquid Subcooling may be accomplished with a sectionof circuits in the coil. Liquid outlet temperature willapproach the entering air temperature by approximately5°F. Benefit is not economical unless TD is 15°F orhigher.

See Installation & Operating instructions for piping, holdback and fan cycling details.

REFRIGERAnT LInE CAPACITY DATA

n Capacity is compressor suction tons for application between -40°F and +40°F suction at condensingtemperatures between 80°F and 120°F sat.

n For multiple or unloading compressor applications, the vertical discharge riser from the compressor may need to be one size smaller.

n This table data is only to be used as a guide. For exact values, please calculate to your specific job linelengths and design pressure/temp values using ASHRAE handbook or ARI refrigerant tables.

n Pressurtrol-Electronic pressure control with single point pressure transducer cycles fans in response to condenser pressure. Set points and differential for each step are adjustable.

n Thermal Pressure Fantrol-Electronic temperature control cycle fans in response to entering air temperature, except for header end fan(s). Header end fan(s) are controlled by pressure control.

n Variable Speed Control-Header end fan(s) arecontrolled with a speed controller in response tohead pressure. Electronic pressure control cycles thebalance of fans.

n Fan cycling Sequence-Fans are cycled offindividually or side-by-side in pairs in sequencefrom the end opposite the header to the headerend. Header end fans run continuously ifcompressors are operating.

Control Paneln Standard weather resistant enclosure is mounted on the opposite end of the unit when looking at theheaders.

n Control power is 24, 115 or 230 volts. A transformer is factory installed when required.

n Fan contactor with branch circuit fuse protection. Each motor or bank of motors protected by fuses.

n For horizontal airflow application, consult factory.n Disconnect not included, but may be required tomeet local codes.

Optional Arrangementsn Fan motor contactor and fuses only.n Fan motor contactor and fuses only which operatevia a customer specified solid state board. Circuitboard is factory mounted and wired.

n 50/50 split with two fan wide models. Each side is controlled separately with individual control panels oneach side.

n 50% winter reduction with two fan wide models.The right side fans are isolated in winter. Fans arelocked out via a relay or switch during shutdown.

Low Ambient Controls (Head Pressure Control System)

Fan Cycling Sequence


TABLE A

Piping Schematic For Winter Controln Head Pressure Control for systems with air-cooled condenser is accomplished with two pressureregulating valves designed specifically for this typeof application. When low ambient conditions areencountered during winter operation on air-cooledsystems with a resultant drop in condensingpressure, the Head Pressure control’s purpose is to hold back enough of the condenser liquidrefrigerant so that some of the condenser surface is rendered inactive. This reduction of activecondensing surface results in a rise in thecondensing pressure and sufficient liquid linepressure for normal system operation.

Fan Cycling Controlsn Factory installed and tested fan cycling controlpanels (optional, see below for details).
