What INDEECO does
INDEECO (Industrial Electric Engineering Company), founded in 1929 and headquartered in St. Louis, Missouri, is a privately-held manufacturer of electric heating and thermal management technologies. The company designs and produces a comprehensive portfolio of commercial and industrial heating equipment — including unit heaters, duct heaters, wall/ceiling/floor heaters, radiant heaters, baseboard and convector heaters, explosion-proof heaters, immersion heaters, circulation and in-line heaters, process air heaters, impedance pipe heating systems, tubular elements, bolt heaters, enclosure heaters, specialty heating, control panels, and industrial heat trace systems. Core proprietary technologies include the CLIP-N-FIT® wattage-adjustment feature, self-regulating heat trace cables (HSR, HSRX, LSR, LSRX, MSR, MSRX), mineral insulated (MI) Type K & B heating cables rated to 1100°F exposure, iHeat pre-engineered tubing, and solid-state SCR power controllers with zero-cross fired proportional control. The company maintains ISO 9001:2015 certification across two Missouri manufacturing facilities.
INDEECO operates a dual go-to-market model: a nationwide network of manufacturers' representatives provides local technical sales coverage, while a dedicated OEM group designs, engineers, and manufactures custom electric heaters and controls for original equipment manufacturers in the HVAC industry. Pricing is quote-based and not publicly disclosed. The company serves six customer segments — Commercial Buildings, Industrial, OEM (the three primary segments), plus Rail, Marine, and Military (secondary) — across North America and select international markets. Selectable use cases include process temperature maintenance, freeze protection, comfort heating in hazardous locations, condensation prevention in electrical enclosures, and railcar/marine/shipboard heating.
INDEECO is a subsidiary of ASPEQ Heating Group, a diversified heating solutions conglomerate that in 2025 acquired business assets from Spectrum, Inc. in the electric heating sector. The company employs between 251 and 500 people, reflects over 90 years of continuous American manufacturing experience, and maintains three recognized sub-brands: iHeat (pre-engineered tubing), Ultra-Safe EXP (explosion-proof unit heaters with industry-lowest Ignition Temperature Code rating), and Triad (washdown/corrosion-resistant unit heaters). Revenue is not publicly disclosed.
