2 Warehouse/Industrial Unit Coolers Larkin introduces it s latest line of warehouse/industrial unit coolers for warehouse cooler/freezer applications. With a wider capacity range and the patented Thermo-Flex coil design, these warehouse/industrial unit coolers provide efficient, reliable operation. Larkin has designed many features and options into this product line to give you a superior heavy duty evaporator. Standard Features Aluminum cabinet with bonded white enamel finish for attractive appearance and durablility Thermoflex (five-year limited warranty) is innovative, eliminates leaks, reduces risk of refrigerant loss 850 rpm motors are quiet and reliable Liquid line solenoid wiring harness for faster installation Suction Schrader fitting for easier suction temperature measurement Hinged drain pan and access panels for easy servicing Captive fasteners on access panels for easy servicing no fumbling with loose bolts and nuts Adjustable defrost control can be customized per application Long air throw is ideal for large warehouse and industrial applications Standardized terminal board for easier field wiring Complete hot gas defrost model offering meets more applications Optional Features High CFM motor and fan combinations ( /3/60 and 460/3/60) Totally enclosed motors ( /3/60 and 460/3/60) Low temperature motors for blast cooling and freezing (-31 F to -50 F) Long air throw collars for large warehouse and industrial applications More factory mounted features for easier field installation (consult factory) Insulated drain pan Nomenclature Larkin Warehouse/ Industrial Unit Cooler Fins Per Inch/Defrost A6 = 6 FPI Air Defrost A8 = 8 FPI Air Defrost E6 = 6 FPI Electric Defrost L4 = 4 FPI Electric Defrost G6 = 6 FPI Hot Gas Defrost F4 = 4 FPI Hot Gas Defrost Capacity x 100 (standard motor/fan blade) Model Nomenclature LH A6 850 C P A Vintage Optional Motor Code T = Totally Enclosed Motors V = High CFM Option P = 3 Phase Motor Voltage Code B= /1/60 M = 460/1/60 C = /3/60 X = /3/50 D= 460/3/60 Y = /1/50 E=575/3/60 Z = /3/50 2

3 Thermo-Flex Coil Design Larkin s innovative coil design utilizes a new and unique approach to coil expansion that virtually eliminates the possibility of leaks at tube sheets and coil supports. Our engineers conceived the design through intense analysis of the cause of common coil failures. Through the use of accelerated test procedures and computer simulation, our engineers pinpointed the primary stress points of a coil during its operation. The Thermo-Flex coil design for the unit cooler (patent #5,584,340) allows the coil to flex during periods of defrost which result 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. To prove our claim, Larkin offers a five-year limited guarantee against leaks at tube sheets and center supports for all large unit coolers. Standard Features Units ship in upright position for ease of installation. Hinged access doors on both ends of the unit. Hinged drain pan for ease of servicing and cleaning. Electrical panel features solenoid wiring harness and color coded wiring connections on the terminal board. 3
