The Tridan Flexpander – For semi-portable coil expansion

The Tridan Flexpander - For semi-portable coil expansion

At Tridan International, we developed a unique coil expansion machine known as the Flexpander. The Tridan Flexpander comes in the FE and FE-5 models.  What a Flexpander does is expands mechanical tubes for heat transfer coils. It is unique designs and machines like these that sets Tridan International apart from other companies. By leading the industry in design and innovation, Tridan provides the best solutions for coil manufactures.

Tridan Flexpander Benefits

One of the advantages of our Flaxpander machines is the semi-portable design. YOu can move the machine to where you need it in the shop. The Flexpander – FE can expand two tubes per cycle and handle any work load. The balanced FE allows for you to rotate it to what angle you need it allowing for diagonal, horizontal or vertical expanding. While the FE and the FE-5 both can handle good volumes of work, the Quadpander is ideal for large volume of work.

The Quadpander QE was created for larger commercial or industrial producers. In addition, the QE can handle almost three times that of the FE or FE-5. Also, this helps provide manufacturers with lower cost and more efficiency in producing coils. Another great benefit of the QE is no limitations on the coil length being expanded. In addition, you will have excellent control of the coil dimensions.

While the Quadpander is a great machine, we do offer other coil expansion machines as well. The Super Flexpander – SFE and the Super Flexpander – SFE-4W are also available. The SFE is designed for specialized needs. This Flexpander is designed to expand large diameter coils, unique materials, and thicker wall coils. Both of these Super Flexpanders are currently available at Tridan International.

Finally, we strive to provide the best machinery for the industry. Our innovative machines and reliability set us apart from the other companies. Give us a call today at 217-443-3592 or fill out one of quote forms for a quote on Tridan machines today!

Heat Exchangers and Their Importance

Heat Exchanger

Heat Exchanger does exactly what the name says, they displace heat from one part of your system to another. They do not provide the cooling, but they move the heat to the part where it will be cooled. 

Parts that are heat exchangers are generally known as condensers, evaporators, or earth coils. A great example of a heat exchanger is an air conditioning unit. The heat is transferred and cooled using refrigerant. 

Equipment To Build Heat Exchangers

Of course, to build an HVAC system you need the equipment to do it. That is where Tridan International comes in.  We have been providing HVAC companies with equipment for over 50 years. In addition, we provide the top companies with all the equipment they need. 

We carry machines for every aspect of HVAC system building. Also, we have equipment for:

Romulus, MI – Innovative Automation announced today that it has acquired Tridan International from SKF/Kaydon Corporation. Innovative Automation now owns Tridan in its entirety including all current operations and facilities of Tridan in Danville, IL.

Innovative Automation undertook this acquisition to improve the product line offering and services that it provides to its customers. Combining this Tridan acquisition with the previous May 1, 2018 acquisition of Livernois Engineering, Innovative Automation can now provide services for Roll Formed, Stamped, and Reciprocating Stamped heat exchange technologies. Innovative Automation is now the only North American company that can support all three of these unique technologies.

About Tridan International

Tridan International has been developing technologies and solutions for the global heat exchange industry since 1966 when it was founded in Danville, IL. Tridan will continue operations in this 88,300 square foot facility featuring a fully functional machine shop, engineering, and assembly and tryout area. There are currently 24 employees supporting the operations of the company in support of their worldwide customer base.

About Innovative Automation

Innovative Automation is owned by Ursula and Mike Bongiovanni. IA has been operating in Southeast Michigan since 2000. IA has developed technologies for the manufacturing industry and specifically for the manufacture of reciprocating stamped heat exchangers. The acquisition of Livernois Engineer provided premier level technologies for tooling and manufacture of roll formed heat exchangers. Adding the Tridan technologies to our portfolio is the natural extension to allow for the servicing of the entire heat exchanger industry.

Building A Commercial HVAC System

Commercial HVAC System

There are different types of HVAC commercial systems to choose from. Commercial HVAC System can be of different varieties such as heat pumps, roof top units, chillers, and heaters. Heat pumps extract heat from water or air. A roof top unit are on the roof and use ducts to provide condition air to the rooms. Chillers generate cold water distributed to air cooling coils. Heaters are usually known as hot air furnaces they burn fuel to heat the air.

No matter what type of HVAC system you are trying to build you will need quality parts to achieve your goal. The HVAC system of building is crucial in providing a comfortable environment for the people inside. In addition, a proper HVAC system controls the air temperature in the building but is also responsible for intake of outside air, exhaust of used air, and properly using energy.

Commercial HVAC System Basics

Every HVAC system needs to provide basic functions. The heat needs to always transfer warmer to cooler. You should also consider the control of moist air in the system. Also, take the energy usage into consideration, for example one ton of cooling is equal to about 12,000 btu/hour. Also, when designing and building your HVAC system, you need to determine what kind of zone it will control.

A single-zone system would be controlled by one thermostat. Where a multi-zone systems can have there own spaces with their own thermostat. When building your system parts such as coils, you should use Tridan equipment. At Tridan we specialize in equipment for creating fins and coils for you HVAC System. We have all the equipment you need to fully fabricate and create your HVAC system.

At Tridan International, we have equipment that can handle fin production, tube fabrication, coil expansion, header production and end forming. Finally, contact us today and see what Tridan can do for you!

Michigan Fin Production

Michigan Fin Production Fin Production is essential to any HVAC system. Michigan fin production companies use the industry-leading fin production machines from Tridan International. Fins can be responsible for up to 70% of the heat transfer process.

At Tridan International we have an extensive selection of fin production machines to choose from. One of our popular fin press is the HFP75. This model is for high volume manufacturers.
