Proheat

What Proheat does

Proheat, Inc. is a US industrial heating equipment distributor headquartered in the Louisville, Kentucky area (La Grange), operating as an authorized channel partner for three tier-1 manufacturers: Chromalox, Watlow, and MDI Hot Runner Systems. The company's catalog spans band, cartridge, strip, immersion, tubular, infrared, flexible, and drum heaters; temperature and process sensors (thermocouples, RTDs, pressure transducers); temperature and power controls (1/32 DIN to 1/4 DIN controllers, SCR/SSR relays); heat trace cable products for freeze protection and process maintenance (including Chromalox Thermwire and Mineral Insulated lines); MDI hot runner systems for injection molding; cold-weather and infrared heating solutions; and ancillary consumables such as Slide mold release chemicals and handheld measurement instruments. Proheat carries no proprietary technology stack — it is a pure distribution and value-added technical support business, not a manufacturer.

The business model is direct, authorized, B2B distribution. Proheat sells through a team of account managers and inside sales staff to industrial manufacturers across the United States, supplemented by an e-commerce-enabled website that now supports direct Chromalox ordering by model or part number. Pricing is quote-based with no public list rates; revenue derives from one-time product sales rather than subscriptions or licensing. Value-added services include credit applications, order tracking, stocking programs, delivery programs, RMA processing, and catalog requests. The customer base is concentrated in plastics/injection molding (NylonCraft, LNP Engineering Plastics), packaging (C&M Fine Pack, Rexam), and food/confectionery (Russel Stover), with testimonials emphasizing long-tenured relationships, technical problem-solving, and rapid response times.

Proheat is privately held with 11–50 employees, was founded in 1970, and has no disclosed external investors or funding events. The company recently rebranded to Big Chief, directing existing Proheat customers to gobigchief.com. Operating geographies are limited to the United States with no claims of international footprint. The competitive moat rests on multi-brand authorized access and individual account-manager relationships rather than proprietary IP, data assets, or technology differentiation.

Broad incumbents

• Chromalox: Manufacturer of industrial heaters and heat trace products; one of Proheat's three principal brand partners. Comparable because Proheat distributes Chromalox's full product line, but Chromalox operates at far greater scale and also sells direct.

Direct peers

• Tempco Electric Heater Corporation: US-based manufacturer and supplier of industrial electric heaters, sensors, and temperature controls. Comparable because it sells a similar heater/sensor/controls portfolio to industrial OEMs and injection molders through both direct and distributor channels.

• Vulcan Electric: Manufacturer of industrial electric heating elements including band, cartridge, and strip heaters. Comparable as a heating-element specialist serving plastic injection molding and industrial process customers.
• Wattco: Manufacturer and supplier of industrial electric heaters, immersion heaters, and process heating equipment. Comparable product portfolio and target end markets including plastics, food, and chemical processing.
• Heatrex: US manufacturer of electric heating equipment, heat exchangers, and process heaters. Comparable in serving industrial and OEM customers requiring engineered thermal solutions.
