What Advance Thermal does

Advanced Thermal Corp. (ATC, dba "Advance Thermal") is a privately held U.S. specialty manufacturer founded in 1987 that designs, engineers, and fabricates reusable and removable industrial insulation blankets, jackets, and covers for high-temperature, acoustic, cryogenic, and personnel-protection applications. Operations are anchored in two manufacturing facilities — Wood Dale, Illinois and Jacksonville, Texas — supported by 8 degreed engineers working from a fully integrated CAD system, with a corporate office in Itasca, Illinois. The product portfolio is organized under the HEATAINER® master brand with sub-brands including SPACE-JAK™ (PTFE-coated fiberglass with silver coating up to 550°F), ACOUSTIRAP® (acoustic covers achieving STC 55 and up to 25 dBA reduction, independently tested by Riverbank Acoustical Laboratories), S.L.I.M.® (patented Aerogel-type insulation for submerged manholes; US 7,947,354 B2), STEAMGUARD-1™ and STEAMGUARD-2™ (specialty materials for harsh manhole environments), SPIRORAP® (modulated wraps for small-bore piping up to 1,000°F), and SPIRORAP-style temperature ranges from -150°F to +1,800°F across the broader valve, pump, heat-exchanger, turbine, and instrumentation lines.

The company's revenue model is project-based custom manufacturing priced per specification, supplemented by recurring replacement-cover revenue during planned plant outages, with sales executed through an independent sales representative network covering all U.S. territories and an internal sales engineering team that responds to inbound web/phone quote requests within one business day. A self-serve customer portal (cda.advancethermal.com) supports logged-in customer ordering, drawing management, and engineering calculation tools. Primary customer segments are nuclear power producers in the USA and Canada, steam and gas turbine operators (1,000+ turbines insulated to date), industrial and petrochemical plants, OEM manufacturers, and major utilities and refineries; ATC's two-plant footprint is positioned as a unique capability to run multiple nuclear refueling outages simultaneously under ALARA compliance. The company does not disclose revenue, has no institutional investors or M&A history in the data, and is led by President Joe Pirogovsky.

Revenue model

1. Custom Removable Insulation Manufacturing and Installation: ATC designs, manufactures, and optionally installs custom reusable/removable insulation blankets, jackets, and covers for industrial equipment. Products are custom-measured and engineered per application, sold as one-time fabricated products with optional installation services. Revenue is generated through project-based orders with custom pricing.
2. Aftermarket Replacement Covers: Since covers are reusable and removable, ATC generates recurring revenue from replacement covers for damaged or worn insulation, as well as re-installation services during plant outages. Replacement orders can be placed via phone or email using existing project records.
3. Sales Representative Network: ATC distributes products through a network of independent sales representatives in all U.S. territories who sell to industrial, chemical, petrochemical, and other markets. Representatives are required to have experience selling steam traps, valves, flanges, pumps, and other steam equipment.

Used by nuclear, chemical, petrochemical, and power-generation operators to reduce heat loss and protect personnel.
• SPACE-JAK PTFE-Coated Fiberglass Insulation Patented PTFE-coated fiberglass insulation technology designed for harsh chemical service environments where standard fiberglass would degrade. Sold as a removable insulation system for valves, pumps, and other process equipment.
• ACOUSTIRAP Acoustic Insulation Acoustic insulation product line designed to combine noise attenuation with thermal insulation for turbines and rotating equipment, addressing both worker noise exposure and heat retention in one removable cover solution.
• S.L.I.M. Aerogel Insulation Thin-profile aerogel-based removable insulation for high-temperature industrial equipment where space constraints or extreme temperatures make conventional fiberglass impractical. Targeted at advanced power and process applications.
• STEAMGUARD Removable Covers Removable insulation covers designed specifically for steam system equipment including valves, fittings, and traps, intended to reduce heat loss, improve steam system efficiency, and protect personnel from burn hazards.
• Custom Insulation Engineering and Pattern Design Engineered-to-order design service in which ATC engineers create custom insulation patterns based on customer-supplied equipment dimensions, using computer-aided design to produce a made-to-fit removable cover with claimed 0.001% misfit rate.
• On-Site Insulation Installation Services Direct on-site installation and fit-up services in which ATC crews install the custom-manufactured removable insulation at the customer facility, including during nuclear plant outage windows.

Partnerships

Three partnerships are on record, tiered core and minor.

• Leading Fabric Manufacturers (unnamed)coreStrategic or Co-development PartnerATC works closely with some of the leading fabric manufacturers in the industry to develop unique technologies for demanding insulation applications. This collaboration led to the development of STEAMGUARD-1 (Nomex-based Teflon film) and STEAMGUARD-2 materials capable of withstanding harsh manhole and tunnel environments with high temperatures and corrosive conditions.
• Riverbank Acoustical LaboratoriescoreTechnology or IntegrationATC's ACOUSTIRAP covers are tested for acoustic performance in explicit conformity with ASTM Designation E90-90 and E413-97 by U.S. Government accredited Riverbank Acoustical Laboratories, providing independent third-party verification of STC 55 ratings and up to 25dBA noise reduction claims.
• Fan, Silencer and Exhaust Manufacturers (unnamed)minorStrategic or Co-development PartnerATC has been a preferred supplier of ACOUSTIRAP cover systems to a number of fan, silencer, and exhaust manufacturers who incorporate ATC's sound attenuating products into their own product offerings, exceeding predicted performance and aesthetic standards.
