What Westermeyer Industries does

Westermeyer Industries, Inc., founded in 2001 and headquartered in Bluffs, Illinois, is a specialized manufacturer of high-pressure refrigeration system components and accessories serving commercial and industrial HVAC/R and natural-refrigerant markets. The company's product platform is organized across five families: Oil Management (centrifugal and coalescing oil separators, reservoirs, regulators, filters), Heat Exchange (HEC/HECH/HPC/HESH/HEM condensers, evaporators, coaxial coils, brazed plate), Liquid Management (ASME-certified receivers, suction-line accumulators, air separators), Parts & Accessories (Refri-Shield level gauges, differential pressure monitors, liquid level switches, three-way and Rotolock valves, replacement parts), and Industrial & Natural Refrigerant Products (transcritical CO2 components rated up to 1885–2175 PSI, Hantemp stainless steel ball valves/float switches/check valves, and distributed TH. WITT natural-refrigerant products). Underlying technology includes patented centrifugal oil separation (US Patent #7,810,351 B2), borosilicate coalescing filtration (99.5% efficiency at 0.3 microns), and ASME Section VIII Division 1 / UL / CRN-certified pressure-vessel engineering.

The company operates a direct B2B industrial sales motion with no e-commerce or self-serve ordering; customers engage the sales team via phone (217-754-3277) or email ([email protected]) and receive engineering, custom solutions, and specification support from dedicated departments. Revenue is generated through hardware sales of components and replacement parts to refrigeration contractors, OEMs, supermarket refrigeration providers, industrial process-cooling operators, marine/offshore operators, and natural-refrigerant system integrators. Distribution is exclusively direct; supporting digital tools (QuickSelect mobile app, browser-based sizing calculators, Cross-Reference Search Tool, DCFM chart) reduce customer specification friction but do not generate recurring or subscription revenue.

Westermeyer is a wholly-owned subsidiary of Mueller Industries (NYSE: MLI), a diversified industrial manufacturer, and operates alongside Mueller Refrigeration and Turbotec Products within the parent's climate-family portfolio. The business absorbed the operational shock of a catastrophic August 2022 fire that destroyed over 70,000 square feet of the Bluffs facility and completed a two-year rebuild; in December 2024 it acquired the assets of Hantemp Controls LLC, expanding the stainless steel industrial component portfolio and consolidating it into the Bluffs site by January 2025.
