Walk–In Coolers & Freezers Medium to Large Applications
APPLICATIONS — Inter-Flo unit coolers are ideally suited for a wide range of coolers and freezers. IFA models are designed for use in coolers above 35°F. IFE, IFG, and IFH units are suited for 35°F coolers, when mechanical defrosts are required, as well as for freezers with temperatures ranging down to -30°F.
SIZES — There are 37 models offered, with capacities from 10,500 BTUH up to 69,000 BTUH @ 10°TD. Air flow ranges from 3,320 CFM to 9,130 CFM.
HOUSING — Each unit is constructed with a rust- free, heavy gauge, textured, aluminum housing which is light weight yet extremely durable. Air and electric defrost models have hinged drain pans to allow for convenient servicing and maintenance (Hot Gas drain pans are not hinged). Slotted hangers are provided on all units for fast installation.
COIL — Seamless copper tubes are staggered and mechanically expanded into heavy gauge corrugated aluminum fins to assure maximum heat transfer.
Die formed fin collars are provided for accurate
fin spacing. Heavy gauge hangers are fastened directly to the tube sheet of the coil to provide high structural strength.
REFRIGERANTS — Inter-Flo unit coolers are designed for most refrigerants including, R-22,R- 404A, R-134a, R-502 and R-507. Please specify system refrigerant requirements when ordering. A separate compartment is provided for all refrigerant connections which allows ample room for internal mounting of expansion valves. Inter-Flos can also be used with chilled water or glycol solutions, contact factory for selection.
FANS — Powerful heavy duty aluminum fans are individually balanced to provide vibration free operation.
WIRE FAN GUARDS — Standard heavy gauge wire fan guards are epoxy coated for corrosion resistance. Optional air straighteners are available for increased air throw when required.
MOTORS — PSC-Permanent Split Capacitor or EC- Electronically Commutated, ball bearing type, life lubricated and thermally protected. Inter-Flo unit coolers use either 1/8 HP, 1050 rpm or 1/3 HP, 1075 rpm motors.
Advantages
Design software | Using the mature European design software, according to the actual demand accurate design of heat exchanger, can design the latest refrigerant CO2,R410A, R507A and special low temperature cold agent etc.
|
Heat exchange structure | Supported to the casing by means of a "flating-bed " system that avoids any kind of contact between the heat-exchange tubes and the supporting end plates,assuring a long life for the heat-exchange without leaks. Heat-exchange sections separated and independent for each fan. The standard fin spacing is 2.1mm,Fin pitch up to 12mm for low air pressure drop.
|
Condenser structure | Shape with flexible and changeable,--Flat-bed,W-Bank,V-Bank; Fan direction--blowing and sucking. Finned length up to 12m,Finned height up to 2.7m.
|
Heat Exchange Tube | Using copper content more than 99.9% of special effective teeth threaded pipe, increase the surface area of the tube, improve the thermal efficiency.
|
Casing | Using galvanized sheet case, spraying outdoor powder coatings, and after high temperature curing, high strength of corrosion resistance is strong, the standard color for RAL9003.
