Reflex

What Reflex does

Reflex Winkelmann GmbH is a German manufacturer of heating, cooling, and hot-water preparation systems for buildings, operating as a subsidiary of the diversified Winkelmann Group. Founded in 1996 and headquartered in Ahlen, Germany, the company sells pressure-maintenance equipment (Reflexomat XS), degassing systems (Servitec S and Servitec Mini), water-storage tanks (Storatherm Heat Mini), and hydraulic distribution technology under the SINUS sub-brand. The customer base spans MEP designers, HVAC installers, building operators, and heat-pump integrators across more than 25 European countries plus Singapore, with localized websites and a partner network linking to national industry associations in the UK, Germany, Belgium, the Netherlands, France, and Poland.

The technical stack pairs physical building-system components with a growing digital layer that includes the BIM@Reflex platform with Autodesk Revit plugin (upstream MEP design), the Reflex Solutions Pro design tool, the PROSINUS®X product configurator, the Reflex Control Smart remote-control application (downstream installed-base service), and the Reflex Smart City AR visualization platform. This platform-plus-modules architecture supports both specification workflows and aftermarket service touchpoints; underlying physical-product engineering in degassing, pressure maintenance, water storage, and distribution underpins the offering. Notable 2025 introductions, including Storatherm Heat Mini for heat-pump applications and the BIM@Reflex ecosystem, point to deliberate expansion into renewable-energy-integrated building systems and digital planning.

Reflex operates a primarily direct-sales go-to-market with quote-based pricing, complemented by digital marketing channels (LinkedIn, Instagram, YouTube, newsletter), trade-show presence across Europe, and an industry-association partner network. Revenue is generated from one-time equipment sales, recurring after-sales services (commissioning, maintenance, repairs, spare parts), and professional training delivered through the reflex4experts platform. No revenue figures are disclosed, no external funding activity is indicated, and growth is funded through the Winkelmann Group parent and bolt-on acquisitions including Sinusverteiler GmbH (2014) and Otto Heat (1999).

Direct peers

• Caleffi: Italian-headquartered Caleffi produces hydronic components including air separators, pressure maintenance, and distribution manifolds — directly comparable to Reflex's exdirt, Reflexomat, and SINUS product families for heating and plumbing systems.
• Armstrong Fluid Technology: Armstrong designs pumps, packaged skid systems, and hydronic solutions for HVAC, including variable-speed pumping and pressure maintenance — directly comparable to Reflex's Reflexomat pressure maintenance and skid solutions.
• Flamco (Aalberts Hydronic Flow Control): Flamco manufactures pressure-maintenance vessels, expansion tanks, and air/dirt separators for HVAC and heating systems — directly overlapping Reflex's Reflexomat, Servitec, and Storatherm lines. Most direct head-to-head competitor in hydronic ancillaries.
• Watts Water Technologies: Watts manufactures water heaters, plumbing, and heating-system components (including pressure/temperature relief and hydronic accessories) overlapping with Reflex's heating and water-preparation portfolio across commercial and residential channels.
• IMI plc (IMI Hydronic / IMI Critical Engineering): IMI's hydronic division sells balancing valves, pressure-independent control valves, and system components for heating and cooling — overlapping with Reflex's SINUS distribution/balancing portfolio and addressing the same MEP designers and installers.

Broad incumbents

• Grundfos: Global pump leader with HVAC and heating-circulation pumps, booster systems, and digital pump-management solutions — broader portfolio than Reflex but competes head-to-head in commercial heating-pump and pressure-maintenance categories.
• Wilo: Wilo is a major pump manufacturer with strong presence in HVAC pressure-boosting, heating-circulation, and packaged pump systems — a much larger incumbent overlapping with Reflex's booster and pump-package offerings.
• Xylem: Xylem's building-services portfolio (Bell & Gossett, Wila, etc.) covers hydronic balancing, pressure maintenance, and packaged HVAC pumping systems — broad incumbent competing with Reflex in commercial heating system components.
• Bosch Thermotechnology: Bosch Thermotechnology (Buderus, Junkers, Bosch brands) provides heating boilers, heat pumps, and system solutions across Europe — a broad incumbent that competes in the same end markets and increasingly bundles hydronic ancillaries that overlap with Reflex.
• Viessmann: Viessmann is a leading European heating-systems manufacturer (boilers, heat pumps, system components) — competes with Reflex on integrated heating solutions and increasingly on heat-pump-compatible storage and system integration.
