What Glo-Quartz does

Glo-Quartz Incorporated is a privately held, family-owned US manufacturer of industrial electric heating equipment, founded in 1952 by George Strokes in Tucson, Arizona. The company designs and produces a broad catalog of 12+ heater categories spanning lab heaters, quartz immersion heaters, fluoropolymer (PTFE) heaters, over-the-side and bottom tank heaters, screwplug immersion heaters (NPT and BSPP threads), flange heaters (ANSI and sanitary), circulation heaters, duct heaters (1-150 KW), tubular elements, and medium-wave infrared radiant panels, plus a line of TC1 analog and TCD digital safety controllers. Core technology rests on Strokes' patented quartz immersion heater design combined with magnesium-oxide (MgO) insulated nickel-chromium tubular elements available in multiple sheath materials (Incoloy®, 304/316 SS, copper, titanium, Alloy 800/840), with options such as electropolish surface treatment and proprietary resettable high-limit safety controllers in NEMA 4X enclosures. Flange heaters carry UL Recognized and CSA Certified ratings up to 18 KW, 600 VAC.

The company's go-to-market is a direct, inside-sales model: customers submit specifications via a structured web Request-a-Quote form, phone (520.792.2331 / 800.423.4078), or email, and an Applications Engineer or dedicated Sales Engineer responds with a project-based custom quote. No public pricing, no e-commerce checkout, and no third-party distributor or reseller network are evident. Revenue derives primarily from one-time hardware sales of custom and standard industrial electric heaters, with a secondary stream from replacement thermostats, TC1/TCD controllers, and components for installed Glo-Quartz® equipment. Customers span industrial process heating, plating and surface finishing, plastics/rubber/drying, laboratory/R&D, and highly corrosive chemical processing — all served from a single Tucson manufacturing site under a "Proudly Made in the USA" positioning.

Core offering

Glo-Quartz manufactures and sells custom and standard industrial electric heating equipment, including quartz immersion heaters, fluoropolymer (PTFE) heaters, tank, screwplug, flange, circulation, duct, tubular elements, and infrared radiant heaters, along with thermostats and TC1/TCD controllers. The company specializes in custom and replacement heaters with short lead times and competitive pricing, supported by an in-house Applications Engineer for design and engineering services.

Product overview

Glo-Quartz Incorporated is a single, vertically integrated product family of industrial electric heaters and their supporting controls, not a software platform. Since 1952 the family-owned manufacturer has built a portfolio that spans a single core competency (electric resistance heating) expressed through multiple form factors: Lab Heaters (LHP and L Series) for small-scale scientific use; Quartz Immersion Heaters (Types GN and N) for acid baths; Fluoropolymer (PTFE) Heaters with over-the-side, bottom-tank, screwplug, and flange variants for corrosive solutions; Tank Heaters comprising Over-the-Side Type W and Bottom Type L configurations; Screwplug Immersion Heaters in NPT and BSPP threads; Flange Heaters in standard-watt-density, low-watt-density, and sanitary sanitary-flange variants; Circulation Heaters that combine a screwplug or flange element with a pipe vessel; Duct Heaters from 1 KW to 150 KW; Tubular Elements used both as standalone heaters and as the building block for the other product lines; Radiant Panels (infrared quartz heaters) for thermoforming, curing, and drying; and a Controls line covering thermostats plus the TC1 analog and TCD digital controllers and their replacement components. The screwplug, flange, and tubular element products all reference the in-house TC1/TCD control family, which acts as the connective safety and interface layer across the hardware portfolio.
