E-Tech

What E-Tech does

E-Tech, Inc. (operating as E-Tech Heat Recovery Systems) is a privately held industrial equipment manufacturer founded in 1976 in Tulsa, Oklahoma. The company designs and builds custom-engineered waste heat recovery equipment—economizers (box, condensing, circular/Econopak, and in-stack), waste heat boilers (firetube and watertube), combustion air heaters, process heaters, thermal fluid heaters, convection sections, and heat recovery steam generators. Each unit is custom-designed to customer specifications using ASME-certified manufacturing processes, with condensing economizers achieving up to 96% efficiency and standard configurations pushing net boiler efficiency above 90%. Following the 2019 acquisition of Kentube Engineered Products assets from Fintube LLC, E-Tech is the sole authorized manufacturer of Kentube replacement economizers, formalizing a legacy position in the market.

E-Tech generates revenue through one-time equipment sales priced via custom engineering quotes. The company sells directly from its Tulsa headquarters and through an established network of regional sales representative companies covering the United States, Canada, Central America, and South America. Customers span nine verticals including industrial boiler operations, ethanol production, food processing, petrochemical, pulp and paper, healthcare, automotive manufacturing, pollution control, and rotary kiln operations. The company is founder-owned, independently operated, and bootstrapped with no external private equity or venture capital funding identified in available materials.

Products and services

• Box Economizers Custom-engineered vertical or horizontal gas flow economizers for larger boiler units with capacities ranging from 10,000 to 250,000+ pph; preheats boiler feedwater using flue gas heat to lower stack temperatures.
• Condensing Economizers High-efficiency economizers that cool exhaust gases below their dew point using feedwater-cooled finned tubing, releasing latent heat from water vapor and achieving efficiencies up to 96% while recapturing approximately 1,000 Btu per pound of condensate.
• Econopak™ Circular Economizers Space-saving circular economizers ranging in size from 100 hp to 1,200 hp for fire-tube boilers or up to 45,000 pph for water-tube boilers; no-transition design installs easily on or above fire-tube boiler outlets.
• Economite™ In-Stack Economizers Down-the-stack in-stack economizers custom-made for any existing stack of any diameter; use baffles and shells with solid, serrated, or longitudinal fins to direct gas flow in spaces where standard economizers cannot be installed.
• Combustion Air Heaters Tubular air heaters that recapture heat from combustion products to preheat combustion air, providing up to 2.5% efficiency improvement for every 100 degrees of flue gas cooling; custom-designed with heavy carbon steel casing.
• Process Heaters Direct-fired custom process heaters ranging from 0.5 to 50 mmBtu/hr; vertical cylindrical designs for smaller applications and horizontal cabin heaters for larger ones, engineered to minimize fuel usage while meeting thermal needs.
• Thermal Fluid Heaters High-efficiency units that recover heat from kilns, ovens, incinerators, and other sources and transfer it to thermal fluids for industrial process applications.
• Convection Sections Custom-designed heat recovery units with capacities from 10,000 to 250,000+ pph, located in the cooler area above radiant sections in process furnaces and conventional boilers, featuring finned tubes for enhanced heat transfer.
• Heat Recovery Steam Generators (HRSG) Custom-engineered units combining long-life economizers with evaporator, feedwater heater, and superheater components for peak efficiency, designed to meet specific operating requirements of plants and steam turbine drives.
• Firetube Waste Heat Boilers Custom solutions ranging from 100 to 1,000 HP and up to 300 PSI; force exhaust gases through tubes immersed in water to generate steam economically from waste heat, well suited to petrochemical and thermal oxidizer applications.
• Watertube Waste Heat Boilers Custom solutions from 10,000 to 150,000 PPH and pressures up to 700 PSI; employ water-filled tubes within a gas-tight enclosure for rapid boiler response and accommodate multiple fuels from dirty gas streams to clean turbine exhaust.
• ExhaustMizer™ Affordable exhaust heat recovery solution that recovers and transforms waste exhaust from industrial reciprocating or gas turbine engines into useful steam or hot water, reducing the plant's carbon footprint.
• ThermoCharger™ Plate and frame integrated heat recovery system that cools makeup feedwater and improves economizer performance by up to 3%; hybrid design combining characteristics of standard and condensing economizers.
• Kentube Replacement Economizers Custom-engineered authorized Kentube Engineered Products replacement economizers; E-Tech is the only authorized manufacturer and can custom engineer replacements for any size and type of Kentube economizer.
