The Aldrich Company

What The Aldrich Company does

The Aldrich Company, Inc. is a privately held, Wyoming, Illinois-based manufacturer of firetube boilers and water heaters, founded in 1936 and continuously operating under the tagline "Quality Products By Loyal Craftsmen." The firm designs, engineers, manufactures, and sells ASME Section IV-compliant equipment across four core product families: high-efficiency condensing boilers (A3C Series, up to 12,000 MBH), hydronic boilers (A3W, AVR, AVW, K/L Series, up to 250 BHP), steam boilers (A3S, D/DG Series, up to 250 BHP), and water heaters (WHG/WHO Series, up to 2,063 GPH recovery), with complementary boiler skid/container systems, feed systems, and blowdown separators. Products support gas, oil, combination gas/oil, and digester gas fuel configurations.

The company's go-to-market is enterprise field sales: a network of regional representatives covers all US states, with dedicated Canadian reps in British Columbia and Alberta, and direct international sales handled from headquarters. Customers include healthcare facilities, K-12 schools and universities, government and municipal buildings, craft breweries and distilleries, and broader commercial/industrial process steam users. Pricing is quote-based, determined through representative consultation rather than published rate cards, and revenue is generated primarily through one-time hardware sales of capital equipment with long replacement cycles. Distribution, specification, and service are reinforced through a digital reference center with brochures, ratings, dimensions, and operating manuals, plus a product registration flow for warranty activation.

In November 2024 Aldrich acquired Spokane-based HMA, extending its Pacific Northwest footprint, and the company continues to launch new SKU variants across its A3 platform. No public financials, funding rounds, or institutional ownership are disclosed; ownership commentary indicates the firm is independently held, with Kenneth Aldrich listed as President.
