Loy Instrument

What Loy Instrument does

Loy Instrument, Inc. is a privately-held industrial process control distributor and engineering services company founded in 1937 and headquartered in Indianapolis, Indiana. The company is the oldest Honeywell distributor in the United States, currently holding Honeywell Platinum/Diamond Partner status — the highest tier in the Honeywell distribution network. It distributes combustion, thermal, analytics, and process control products from a line card of 39+ vendor brands (Honeywell Maxon, Eclipse, Kromschroder, Fireye, Belimo, Dwyer, Watlow, Itron, SpecView, and others) across five branch locations in Indiana, Ohio, Michigan, and via KromAmericas (its wholly-owned subsidiary) into Canada. Beyond distribution, Loy provides three categories of paid professional services: (1) engineering services — custom design, panel building, pipe train assembly, and field commissioning with pre-shipment replication of customer electrical schemes; (2) ISO 17025-accredited calibration services through an ANAB-accredited lab serving aerospace (NADCAP), automotive (CQI-9), food, pharmaceutical, and chemical processing customers; and (3) technical training via Tech Tuesdays webinars and in-person Combustion and Flame Safety classes.

The business model is a hybrid of hardware resale (product distribution with markup across warehouse inventory), project-based engineering services (custom control panels, pipe trains, SCADA integration), recurring calibration revenue (ISO 17025 lab and on-site NIST-traceable calibration), and training fees. Pricing is B2B quote-based with no public rate cards; multi-year contracts and counter-sales/credit-application onboarding via DocuSign are standard. The company primarily serves industrial heat treat plants (batch/continuous furnaces, annealing, tempering, carburizing, vacuum heat treating), aerospace heat treat operations requiring NADCAP/AMS2750 compliance, food processing effluent pH control customers, and commercial/institutional combustion customers, with deep technical expertise rooted in 500+ years of combined in-house process control and combustion experience.

Customer acquisition and retention are driven by a regional sales engineering footprint (inside sales for small/mid accounts, field sales engineers for major OEM and heat treat customers), five stocking branches for counter sales and emergency parts availability, an active technical content engine (weekly blog posts, Tech Tuesdays webinars on Microsoft Teams, archived on YouTube), and co-marketing with Honeywell through in-person roadshows hosted at branch locations. The company has accumulated at least ten Honeywell Channel Partner of the Year recognitions between 2002 and 2023 and currently holds Platinum Distributor Partner status.
