Coil Expanders

At Tridan International, we have a wide array of coil expansion machines that can handle your needs.

Our Coil expanders become more beneficial with end sizing of tubes.  They can easily be shaped as bell and flare or just bell to custom specifications and fully ready for bend insertion. Many industries use the products that are made using our tube expansion machinery.  HVAC system and heat exchanger manufacturers, for example, use them for building products. Those, in turn, are used in many factories and industrial complexes worldwide.

What are Coil Expanders?

Coil expanders are specialized hand or pneumatic tools designed for expanding the ends of tubes or coils. Their primary function is to create snug and secure tube-to-tube sheet connections in HVAC systems, heat exchangers, condensers, and various industrial equipment. By carefully expanding the tube material, these tools ensure that the coil assembly remains tight and resistant to leakage, despite high-pressure working conditions.

Depending on your specific use case, coil expanders come in several variations, including manual, hydraulic, and pneumatic options. They are typically crafted with precise engineering tolerances to handle thin-walled tubes made from materials like copper, aluminum, or stainless steel.

Why Coil Expanders Matter in Engineering?

Efficient coil and heat exchanger performance largely comes down to how secure and optimized the component connections are. In addition, here are four key reasons why coil expanders are non-negotiable in your toolkit:

• Leak Prevention
• Improved System Longevity
• Optimized Thermal Efficiency
• Simplified Maintenance and Repairs

They are crucial for many industries such as HVAC systems, refrigeration/cooling systems, power generation, and industrial manufacturing!

Horizontal or Vertical Expander Machines

Tridan International is one of the nation’s leading manufacturer of tube expanding machines. With our extensive line of coil and tube expanding machines, we have machines that can accommodate any size business. Horizontal and Vertical, from high volume to low volume, we have it. Also, we offer semi-portable expansion machines as well. For example, the Flexpander-FE is one of our most popular models. The FE model can expand two tubes per cycle, which then allows it to expand coils with a U-bend or straight tube.

The quality Tridan brand name brings reliability and durability to every product we offer. We have been a leader in our industry since 1966. Based in Illinois, our products are used all across the globe today. Tridan stands by all our products, and we offer parts and service for our machines.
