Thermo-Cycler Industries Inc. was started by Donn Kelver and has been specializing in energy efficient industrial heating and ventilation since 1984. After spending over 20 years managing the sheet metal division of a mechanical contracting firm, Donn skeptically installed a large airturnover system in a local factory in the early 1970s and went from skeptic to believer after seeing it in actual operation. A few years later, he became a regional sales representative for the Johnson Heater Company and successfully sold many systems for warehouses and large industrial manufacturing buildings in Indiana, Michigan and Illinois. In the early 1980s, with buildings becoming better insulated and more attention being given to energy efficient heating, Donn felt there was a growing need for airturnover equipment that could offer similar energy savings and comfort in smaller buildings that ranged from 10,000 sq. ft. to 100,000 sq. ft. In September of 1984, the Thermo-Cycler GTC-400 was born to serve that need. Having spent many years as a heating contractor rather than a manufacturer, Donn also understood the special needs of those contractors. He built a contractor friendly company to accommodate those needs and especially those of heating contractors who work closely with design-build general contractors.Over the last 31 years, our product line has expanded and Thermo-Cycler Dealers have installed our system in thousands of buildings where they have been saving energy and improving the working conditions of employees in millions of square feet of warehouses, manufacturing buildings, athletic fields, and other large open area buildings. Our management team has many years of personal experience in HVAC contracting, manufacturing, sales and maintenance, and in solving real life heating problems. Although we are experienced and very familiar with other types of conventional heating equipment such as infrared, direct fired makeup air heaters, and conventional unit heaters, we specialize only in comfortable, energy efficient airturnover heating and ventilation applications for industrial buildings and warehouse. Unlike huge corporations that try to be everything for everybody, we are pretty much a one trick pony and do not do schools, hospitals, offices, small stores, or residential construction. In many areas of the country, we are proud that our team also includes local representatives who offer additional experience, products, and solutions to tough heating problems. We are ready, willing and able to assist as a core part of the professional construction team for your next project.
