What Chromalox does

Chromalox, founded in 1917 and headquartered in Pittsburgh, Pennsylvania, is a global supplier of industrial electric thermal technologies serving process heating, tank heating, steam generation, and heat trace applications. The company designs and manufactures a portfolio that includes immersion heaters (flanged, screw-plug, and circulation), air and radiant heaters, process heaters and controls, steam generators and boilers, heat trace cables and controls, and component technologies (cartridge, flexible, strip, ring, and tubular heaters), operated from facilities including a manufacturing site in Ogden, Utah. Underpinning the portfolio are proprietary innovations: DirectConnect™ Medium Voltage technology operating up to 7200V with nearly 100% efficiency, a patented removable heating element design that allows maintenance without draining tanks, the XtremeDuty™ platform for extreme environments, and a patent-pending DirectConnect converter system with dry-out logic and IEC 62477-compliant safety features.

The company's revenue model centers on custom-engineered hardware sales through direct enterprise field sales, supplemented by a Pick & Ship rapid-delivery program offering pre-designed units at optimized price points, and a professional services line covering site installation, startup, commissioning, and operator training. Pricing is quote-based for custom multi-year contracts and unit-based for Pick & Ship, with no public price disclosure. Customers are enterprise industrial buyers organized across four primary verticals: Energy (oil & gas, nuclear, sustainable energy), Advanced Technology (aerospace & defense, semiconductor), Materials Processing (engineered chemicals, composites, building & construction), and Health & Nutrition (food & beverage, pharmaceuticals). Chromalox operates as the core electric thermal technologies subsidiary of UK-listed Spirax Group plc, leveraging the parent's global distribution and resources, and pursues a content-driven GTM combining direct sales representatives, regional "Locate a Rep" coverage, case-study-led demand generation, and active participation in industry events such as NISTM 2026 and DECARBON 2026.
