About Your TRIDAN® FE-3 / FE-4 Flexpander: The Model FE-3 / FE-4 Flexpander provides low cost capability for mechanically expanding circulation tubes in heat transfer coils. It is designed to expand two (2) tubes per cycle and may be used with straight tube, U-bend or hairpin tube construction. The Flexpander may also be equipped with a tube-slitting tool for the removal of damaged tubes from heat exchanger coils. This equipment is ideal for large custom coils, experimental coils and limited production orders. Listed below are some of the features that make the TRIDAN® FE-3 Flexpander a popular choice for many heat exchanger coil manufacturers. Versatility: Simply by changing tool sets, the Flexpander will expand tubes of copper, aluminum and other thin walled material, with outside diameters of 5/16 in. (7.94 mm) to 3/4 in. (19.1 mm). Tube centers may vary from 3/4 in. (19.1 mm) to 3 in. (76.2 mm). There are virtually no limitations on length of heat exchanger coil tubes that can be expanded. When standard Flexpander equipment cannot be tailored to meet your requirements, contact your TRIDAN® representative for technical assistance and price quotation on custom or specialized equipment for your heat exchanger coil manufacturing applications. Precision: Flexpander tube expansion is a mechanical process that gives uniform and precise control to the amount of fin to tube bond. Minimum lubrication is required for the expansion process, eliminating the drying and cleaning problems experienced with hydraulically expanded coils. In addition, this process minimizes over all coil shrinkage normal to an expansion process. Productivity: The Flexpander will expand tubing at a rate of forty (40) to fifty (50) feet per minute. Clamping and unclamping of the tube ends is automatic with the cycling of the equipment. The operator is only required to place the Flexpander clamp jaws over the tube ends and cycle the machine. A well-trained operator can do tool change and set-up quickly. The Flexpander may also be equipped with an AUTO-CYCLE function. This function will allow the operator to place the Flexpander over the tube ends and press the switch, causing the unit to clamp the tube ends and cycle through the forward and backward stroke automatically, minimizing wear on clutch discs. Kits are available for connecting two Flexpanders to the same hydraulic power unit. Each Flexpander may then be equipped with tool sets for use on coils with different tube sizes or spacing, making a significant savings in tool change and setup times. Multiple Flexpanders attached to the same power unit should not be operated at the same time.

Removal of Packing Material and Protective Coating: Your equipment was carefully packed at the factory to minimize damage and corrosion during shipment. Carefully remove all packing material from the equipment. Remove all corrosion protective coatings, and other foreign matter from the equipment, using an oil base naphtha solvent or other appropriate solvents and cleaners. Use only in a well ventilated area. DO NOT use solvents that are harmful to clutch surfaces or other equipment finishes. All cleaner and solvent residues must be removed from the equipment. After cleaning, coat all surfaces that are subject to corrosion with a light coat of #10 weight machine oil. OPERATIONS SITE AND POWER PREPARATION: Electrical: Electrical components for your TRIDAN® equipment are supplied to your specified power requirements. Verify that electrical service voltage, phase and Hz match equipment requirements. Electrical services for this equipment should be provided through a main disconnect switch. After electrical connections are made, check the hydraulic power unit motor rotation for proper direction (clockwise CW at fan end of motor). Change direction if required. All electrical connections must be made in accordance with the National Electric Code (NEC) and existing local codes. Hydraulic Power Unit: All hydraulic power units are shipped WITHOUT hydraulic fluid. Securely mount the hydraulic power unit assembly in a well-ventilated area in the work site. Fill the reservoir with good quality hydraulic oil. Use TRIDAN® HYD-46-AW or equal (approximately 10 gal. NOT INCLUDED). Insure the fluid registers on the sight gage. DO NOT over fill. Additional fluid may be required after equipment is cycled and all pumps, cylinders and hoses are filled. DO NOT RUN THIS UNIT WITHOUT FLUID. Operator Work Space And Safety: Adequate space must be provided to accommodate the coil and coil fixture and the length of the expander rods in the extended position. Expander rods should not extend into other work areas, personnel passageways or other machine operations. The Flexpander should be suspended by a TRIDAN® Model TB-1 tool balancer to offset the weight of the equipment (approximately 80 lb.). Mount the balancer at a convenient position and height for maneuverability, adjustment and operator safety.

Section TWO Flexpander Assembly and Adjustment Setup: Your equipment has been assembled, lubricated, adjusted and tested at the factory, to insure proper operation. However, due to shipping requirements and regulations and whether the equipment was ordered with or without tools, it may be necessary to perform some or all of the following lubrication, assembly and adjustment procedures. Lubrication: Remove clutch drive gear cover (see fig. 1). Lightly coat clutch drive gear (A) and clutch gears (B) with Lubri-plate No 930-2 or equal. Insure that lubricant does not come in contact with clutch disk plates. Any lubricant on clutch disk plates (C) will cause slippage and equipment malfunction.

Fig. 1 Remove housing cover assembly, not shown (see fig. 2). Lightly coat drive gear shafts (D) and expander rod drive gears (E) with Lubri-plate No 930-2 or equal. DO NOT over grease. Insure that the drive groove on the expander rod drive gears is dry and free of lubricant. Replace housing cover assembly.

Insert a 1/4-in. dia. steel rod through the hole in the bottom of the housing assembly and into the hole in the clutch drive gear, locking the drive gear assembly. Loosen the #10-32 lock set screw in the clutch adjustment nut. EXPANDER RODS MUST BE IN PLACE. With a torque wrench (provided), torque the clutch adjustment nut to approximate 22 to 24 ft. lbs1. Adjust both clutches and retighten setscrews. With the drive gear still locked, turn on the hydraulic power unit. Using the manual cycle switch, turn on the Flexpander. The clutches should slip at a reading of 900 to 950 psi on the hydraulic power unit pressure gage. Replace clutch drive gear cover assembly. Remove steel locking rod. DOUBLE NUT Installation of the Double Clutch Nuts: EXPANDER RODS MUST BE IN PLACE! Insert a ∅1/4-in. steel rod through the hole in the bottom of the housing assembly and into the hole in the clutch drive gear, locking the drive gear assembly (see Fig. 8). Put inner lock nut on first, (EB12066) with the flat side towards the Belleville washer. The outer clutch nut goes on next (EB12067), it has the three (3) #10-32 set screws. Thread the outer nut up to the inner nut, and then back it off until the torque wrench will fit on both of them at the same time. Tighten the setscrews against the other nut with enough pressure that they can both be turned by hand. Thread the nut assembly up to the Belleville washers, and then tighten the assembly to approximate 22 to 24 ft. lbs1, and then tighten the setscrews. Double Nut Torque Adjustment: EXPANDER RODS MUST BE IN PLACE! Insert a ∅1/4-in. steel rod through the hole in the bottom of the housing assembly and into the hole in the clutch drive gear, locking the drive gear assembly (see Fig. 8). Loosen the three (3) #10-32 x 1/4” set screws enough to be able to turn both nuts at the same time. Adjust the nuts so they both can be turn at the same time with the torque wrench. Torque nuts down to approximate 22 to 24 ft. lbs1, and then tighten the setscrews back against the inner nut to take slack out of the clutch nuts. Expander Rod Tips and Stops: If the expander rods do not have premounted brazed on tips, mount expander tips on expander rods. Mount expander rod stops on expander rods. Adjust stops to required length of stroke and then tighten.

1 Torque adjustment can be greater or less the 22 to 24 ft lbs list, varying on the type of rod, or tubing used.

Section THREE EQUIPMENT OPERATION: Load fins and secure in fixture (furnished by customer). Insert tubes into fins to make the coil. Lubricate inside ends of tubes with TRIDAN® TL-4AEX Copper Tube Lubricant, light oil or other lubricant. Reverse toggle switch to retract expander rods into clamp jaws, against clamp jaw rod stops. Position Flexpander so that clamp jaws are over two (2) adjacent tube ends. Normally, the tube ends will extend into the clamp jaws a 1/2 inch, or by a distance equal to the diameter of the tubes, whichever is greater. NOTE: If hairpin or U-bend tubes are used, it will be necessary to expand both sides of the same tube simultaneously. Press the toggle switch to allow the expander rods to move forward. The clamp jaws will close and grip the tubes. The expander rods will move through the tubes to the end of the pre-set stroke. Reverse the toggle switch and the expander rods will retract through the tubes and into the clamp jaws, against the rod stops, opening the clamp jaws and completing the cycle. NOTE: Release the toggle switch as quickly as possible after the completion of the forward or reverse stroke, to avoid excessive clutch slippage. Repeat the cycle as required. NOTE: Flexpanders equipped with AUTO-CYCLE switches will cycle through forward and reverse strokes automatically. For single tube expansion operations, the Flexpander will be operated with one expander rod. FLEXPANDER AUTO-CYCLE Equipment Operation – Automatic NOTE: Flexpanders may be equipped with limit switches that allow the machine to cycle through forward and reverse strokes automatically. These switches are mounted on the clamp jaws and on the rear of the hand guard. The operator places the clamp jaws over the ends of the tubes and presses and releases the thumb toggle switch. The expander rods will move forward through the tube to expand it. When the rod stops on the expander rods make it to the limit switches mounted on the hand guard, the flexpander will automatically reverse and retract the rods. At the end of the retraction stroke, the action of the clamp jaws opening will make the limit switch mounted on the clamp jaw and stop the machine. The jaws will be open and ready for the next cycle. The direction of the stroke may be reversed at anytime by pressing the toggle switch. However, the stroke cannot be stopped. It will only stop on completion of the stroke.

12

AUTO-FE: AUTO CONTROL CYCLE On Flexpanders equipped with the AUTO-FE auto control cycle have a selector switch labeled MAN, AUTO. The selector switch must be set to the operation mode desired. When placed in the MAN mode, the operation is the same as for a Flexpander without limit switches. When placed in the AUTO mode, the operation is the same as for a Flexpander with limit switches. These Flexpanders are also equipped with an adjustable rod stop timer inside the control panel. This timer may be set to insure that both expander rods have time to complete their travel. This is particularly helpful on long expander rods. DO NOT INCREASE THE TIME UNNECESSARILY. The timer allows the clutches to slip for a set time and may shorten the wear life of the clutches. For single tube expansion operations on all models, the Flexpander will be operated with one expander rod. TUBE SLITTER OPERATION: A tube slitter tool kit is available for use with the Flexpander to facilitate removal of damaged or defective tubes from heat exchanger coils. Flexpander tube slitters are designed to be used with hardened rods. Rods are available from TRIDAN® International, Inc. and are normally included in the tube slitter tool kit. Substitute rods may damage Flexpander rod drive gears and void machine warranty. Remove expander rod stops from expander rods. Loosen the clamp jaw assembly clamp cap screw and remove both rods from the Flexpander. Remove the clamp jaw assembly from the Flexpander. Install a tube slitter rod through the Flexpander expander rod drive gear assembly. If expander rods are equipped with threaded tips, one of the expander rods may be used for the tube slitting operation. Place the tube slitter backup sleeve over the end of the tube to be removed. Position the Flexpander to place the slitter rod into the backup sleeve and into the tube to be removed. Using the toggle switch, cycle the tube slitter rod through the defective tube. NOTE: If damaged tube is in the outer row of the coil, insure that the tube slitter is rotated away from the face of the coil. Insure that the tube slitter cutter bar is adjusted to extend beyond the diameter of the tube slitter body by .015 inch plus the thickness of the expanded tube material. At the other end of the tube, attach the tube slitter tool to the rod. Reverse the switch and retract the tube slitter tool through the tube. Remove the strip cut from the defective tube. Remove the defective tube.
