Features and Benefits

These innovative and efficient units serve a variety of commercial and industrial applications. With sizes ranging from 10,000 to 71,000 BTUH and a modular design only 24 inches high, these quality unit coolers are the easiest to install and the most economical to operate.

Features• All electrical components factory wired to

terminal board and identified, making it easy to field wire the unit

• All electric defrost models have adjustable defrost termination and fan delay thermostat

• Front-hinged drain pan for easy access• Schrader valve provided for suction

pressure measurement• External equalizer connection• Terminal board design simplifies wiring

between the evaporator and condensing units

• Thermally protected, lifetime-lubricated PSC motors in 115, 208-230 and 460 volts

• Reliable nickel steel alloy defrost heater elements

• Heavy gauge textured aluminium cabinet• All internal panels have been “isolated”

which provides for quiet unit operation• Motors plug into wiring harness for

easier servicing• Heaters are coil face mounted for

easy accessOptions

• UL approved totally enclosed motors• Duct fitting for air sock• Wire fan guards for air diffusion• Available in stainless steel cabinets and/or

drain pan• Factory mounted components: pre-

assembled TXV, liquid line solenoid valve and room thermostat

• Glycol circuiting• Copper fin or coil coatings• 575 volt units

InnovativeThermo-Flex™

Coil DesignLarkin’s innovative coil design utilizes a unique approach to coil expansion that virtually eliminates the possibility of leaks at tube sheets and coil supports.

The Thermo-Flex™ coil design for the unit cooler* allows the coil to “flex” during periods of defrost resulting in expansion of the coil surface. By eliminating the possibility of wear at critical stress areas, the integrity and longevity of the unit are dramatically increased. The result is a product which greatly enhances overall system reliability and reduces risk of costly refrigerant loss.

Larkin offers a five-year limited guarantee against leaks at tube sheets and center supports for all medium profile unit coolers.

Internal grooved tube for increasedheat transfer efficiency

Factory installed liquid line solenoid wiring harness for faster installation
