Unit Description
The Thermo-T tubular heat-exchanger is designed to recover heat from energy-consuming processes up to 1800°F. Energy can be recovered and returned as process make-up air, used to preheat combustion air, or used for plant or office heating.
Thermo-T offers fully adjustable tube-size and tube-spacing. Combine this with the unmatched flexibility in materials of construction and flow patterns, and Thermo-T is the obvious choice for your high-temperature heat-recovery application. To meet unique performance or configuration requirements, both single-pass and multi-pass models are available.
The Thermo-T can be integrated with a plate-style heat-exchanger (Thermo-Z) to provide the ultimate in effectiveness, reliability and value.
The Thermo-T heat-exchanger is designed and constructed for an industrial environment. Proper material selection is crucial to the life of a heat-exchanger. Typically, Thermo-T is constructed with 304L, 316L, or 309S stainless-steel tubes and tube sheets. These materials provide superior performance in high-temperature or corrosive environments.
Optional materials are available to meet specific needs. The tubes are mechanically expanded into and then fully welded to the tube sheet. This provides a double layer of protection to ensure against cross-contamination. The tube size and spacing are fully adjustable at the time of manufacture to meet exact performance requirements.
The inner casing is constructed of the same material as the heat-transfer matrix. It is welded to the matrix at certain peripheral locations to assure an air-tight seal.
Thermal stress is another major factor in high-temperature heat-exchanger design. At high temperatures, Thermo-T's integral expansion joints allow the tube/sheet assembly to expand without causing excessive stress. The outer casing remains cool because of the layer of high-temperature insulation. The internal casing is secured to the cold outer casing by means of integral thermal expansion joints. These joints allow the inner matrix/casing assembly to move about freely without undue forces being imposed on it by the rigid, cool external casing. A layer of high-temperature insulation keeps the outer casing cool. Therefore, it will not expand as a result of process temperature changes.
The heat-exchanger (with its cold flanges) can be installed flange-to-flange to the ductwork without the need to compensate for the thermal expansion of the heat exchanger.
