Tube Expansion Machinery

Tube Expansion Machinery Quadpander - QETube expansion is the process of reducing a tube’s wall. At Tridan International, we have a variety of tube expansion machinery to choose from. Our expansion machinery is available in horizontal, vertical, semi portable, and tube end expansion.

Horizontal Tube Expansion Machinery

The horizontal expanders, such as the Cellular Horizontal Expander-CHE  can expand and at the same time, add the final belling to a tube. This type of expander uses no hydraulics and has very little change over time for different coil sizes. If you are looking for a more portable solution, the Flexpander-FE is your answer. This semi-portable horizontal tube expander can expand two tubes per cycle. Because of it sizes, it makes it more versatile for smaller shops.

Vertical Tube Expansion

The vertical line is composed of the Double Sided Conventional – DE, LDE-Low Profile – Double Side, LSE – Low Profile – Single Side, Low Profile Expander – LSEM, and the Single Sided Conventional – SE. The vertical machines are designed with saving space in mind. The double sided machines are capable of doing two separate jobs at once to save time. The low profile machines are designed to save up to 22% in head room.

Semi-Portable Expanders

Semi-portable expanders are designed to be much more mobile than the larger counterparts. Because of the more versatile portable systems, they are ideal for smaller shops. Also, they can still produce a large amount of volume.  Finally, our tube end sizers are used for sizing of the thin walled copper. The tube end expansion are the Tube End Sizer – BTM, Tube End Sizer – BFA, Tube End Sizer/Air Operated, and the Tube End Sizer/Hydraulic – BTH.

As you can see, when it comes to tube expansion machinery, Tridan has you covered. From horizontal to vertical and even semi-portable, we have machines to fit any size shop. Get your quote today for your next tube expansion machine!

Tube Expanders for Heat Exchanger Manufacturers

Tridan International, Inc.  provides heat exchanger production machinery to manufacturers worldwide.

Heat exchanger manufacturers  looking for durable machinery that will provide decades of dependable operation, choose Tridan. We know that our customer service and support is the key to our customer’s satisfaction.  In today’s competitive environment, it is important to have machinery that has the strength to withstand the forces of daily production. Tube expanders for example, can have a heavy-duty, high volume schedule. In other applications, the semi-portable Flexpander tube expander for coils may better serve the manufacturing environment. Regardless, Tridan’s strength and quality help customers maintain a reliable flow of accurately produced parts.

We offer a wide range of machinery and tooling for Fin Stamping, Coil Expansion (tube expanding), and  Tube Fabrication applications such as Cut to Length, Hairpin Benders, Return Benders, End Sizers and Braze Ring Loaders.

Newest heat exchanger tube expanders

Tube expanders for heat exchanger manufacturersOne of Tridan’s newest and most successful offerings is the Model CHE Servo-Powered Cellular Horizontal Expander.  It is designed for the simultaneous tube expansion and final belling of all tubes within small to medium sized coils.  Its PLC control system allows for very precise, fully-automatic setup of varying coil lengths.  By simply choosing a coil model from a pre-programmed menu, the machine will automatically cycle the distance required.  The setup for the coil width and height are manual, however, it requires minimal effort and time by design. The precision tooling and fixture features of the CHE reduces or eliminates the need to add or remove pattern tooling in the machine in order to accommodate varying coil sizes!

The CHE horizontal expander uses no hydraulics.  The tube expansion stroke is actuated by a very powerful and rugged servo motor that drives a precision high-capacity roller screw which cycles the expansion ram.  The operation of the machine is very clean and exceptionally quiet compared to conventional hydraulic-powered expanders.  Energy consumption is also reduced since the machine only consumes electricity when it is actively cycling.

We are currently working on several new designs that will be made available to coil / heat exchanger manufacturers. Look for updates and announcements in the coming months and be sure to visit us at the AHR EXPO in January.
