What Marley Engineered Products does

Marley Engineered Products, LLC is a U.S. manufacturer of supplemental electric heating and ventilation equipment serving commercial, industrial, and residential end markets. The company operates as a wholly owned subsidiary of SPX Corporation, a diversified industrial conglomerate, and runs a portfolio of three established brands — QMark, Berko, and Fahrenheat — that together address distinct customer segments under a unified product, engineering, and distribution organization. Its headquarters are in Bennettsville, South Carolina, with a former operating location in Peru, Indiana (historically the Berko Electric site) consolidated under the Marley entity.

The core product portfolio spans electric baseboard, wall, ceiling, unit, garage, duct, infrared, radiant, hazardous-environment, portable, specialty (toe-space, floor drop-in, utility well-house) heaters, commercial heat trace systems, and industrial/commercial ceiling fans for destratification and air circulation. Controls and thermostats — including the SmartSeries Plus digital touchscreen with BACnet MT/TP BMS integration, Z-Wave smart-home connectivity, and supporting contactor panels and SSR controls — represent an increasingly important product layer that connects standalone heaters to building management platforms. Technical differentiators include UL/ETL/cULus certifications on industrial SKUs, patented installer features such as CLIP-N-FIT, and proportional heating technology that maintains temperature within 1.5 degrees of setpoint versus approximately five degrees for conventional bi-metal thermostats.

Revenue is generated through B2B hardware sales via a nationwide network of manufacturer sales representatives and wholesale distributors, supplemented by direct export sales. Pricing follows published price lists with 30-day payment terms domestically and cash-in-advance or letter-of-credit terms for export orders. The go-to-market emphasizes specification-grade products sold to architects, engineers, contractors, and facility managers, supported by BIM Revit libraries, spec sheets, submittals, and educational content through Marley University and E-Heat-U webinars. Custom solutions, including the Hidden Heat THX concealed product line, extend the addressable market into design-sensitive and architect-specified applications.
