Coroxyl

What Coroxyl does

Coroxyl SAS is a privately-held French micro-company (1–10 employees, registered capital of 10,000 euros) headquartered in Barsac, Gironde, that sells water-treatment products and equipment to professional installers and technicians in metropolitan France. Its catalog is built around three integrated pillars: (1) proprietary COROXYL-branded chemical treatments — including the pH-neutral C1 corrosion and scale inhibitor, C2 sealant for micro-leaks, C3/C4/C20 cleaners, SOL4 solar cleaner, S1/S2 sanitary descalers, and Démin demineralization — covering the full lifecycle of heating, cooling, solar, and sanitary circuits; (2) branded filtration and separation hardware under the SpiroTrap, SpiroVent, SpiroCombi, SpiroTop, and SpiroCross lines, sourced via a distribution relationship with Spiro Energy, including magnetic sludge separators (notably the SpiroTrap MB3 with 20-year warranty and 5 µm filtration), air separators, combined air/mud separators, and hydraulic distributors; and (3) installation and diagnostic equipment — flushing machines (Désemboueuses 5.2–9 bar), descaling units (Détartreuses), solar pumps, thermal cameras for iOS/Android, and water analysis kits/test strips.

The business model is exclusively direct-to-professional B2B e-commerce: customers must register a professional account to view pricing. Standard accounts pay by card at order confirmation; Premium accounts receive vendor-issued credit limits with 30-day deferred invoice terms. Pricing is not publicly disclosed for unauthenticated visitors. Sales are restricted to metropolitan France excluding Corsica, with delivery governed by French sales terms (CGV). The company uses no distributors, resellers, or retail channels. Go-to-market relies on the website storefront, a newsletter subscription, downloadable technical datasheets, and a phone support line operating weekdays 8:00–12:00 and 14:00–17:30. Marc Jacob serves as director of publication and the operating principal; no other executive team, board members, investors, or external capital sources are disclosed.

Core offering

Coroxyl manufactures and distributes water treatment chemicals and filtration equipment for heating, air conditioning, solar, and sanitary systems. The company offers its own COROXYL-branded chemical formulations (inhibitors, cleaners, descalers, demineralizers) along with Spiro-branded magnetic filters, air separators, and flushing/descaling machinery. Its offerings are aimed at professional installers, heating technicians, and industrial facility managers for preventive maintenance and hydraulic circuit protection.

Product overview

Coroxyl is a French company specializing in water treatment products and equipment for heating, cooling, and solar installations. The product portfolio consists of three main categories: (1) COROXYL branded water treatment chemicals including corrosion inhibitors (C1), sealants (C2), cleaning products (C3, C4, C20), solar cleaners (SOL4), sanitary descalers (S1, S2), and demineralization products (Démin); (2) Industrial and domestic filtration systems under the Spiro brand (SpiroTrap, SpiroVent, SpiroCombi, SpiroTop, SpiroCross) for mud separation, air separation, combined air/mud separation, vacuum degassing, and hydraulic distribution; and (3) Equipment including flushing machines (Désemboueuses) in 5.2/8/9 bar variants, descaling equipment (Détartreuses), solar pumps (Solar Express, Solar System, Solar 70/8), thermal cameras for diagnostics, and testing/analysis products. These products work together as an integrated system approach to maintaining water quality in heating/cooling installations—from chemical treatment and filtration to cleaning equipment and water quality testing.

Direct peers

• Fernox: UK-headquartered leader (owned by MacDermid Enthone) in water-treatment chemicals, magnetic filters, and air/dirt separators for residential and commercial heating systems. Directly comparable to Coroxyl across both the chemical inhibitor line and the branded filtration hardware sold to professional installers in Europe.
• Sentinel Performance Solutions: Specialist in water-treatment chemicals and equipment for heating, cooling, and solar systems, owned by Italmatch. Closely overlaps Coroxyl's chemistry-plus-equipment offering and targets the same professional installer channel across Europe.
• Adey: UK-based manufacturer of magnetic filters (e.g., MagnaClean) and chemical inhibitor ranges for hydronic heating circuits. Competes head-to-head with Coroxyl's SpiroTrap MB3 and COROXYL inhibitor line at the professional installer counter.
• Cillit: Heating and sanitary water-treatment brand (part of the BWT group) producing inhibitors, descalers, and filtration solutions for hydronic circuits in France and across Europe. Direct overlap with Coroxyl's chemical-and-filter proposition targeted at installers.

Broad incumbents

• Watts Water Technologies: US-headquartered global manufacturer of water-related products including heating-system treatment chemicals, isolation valves, and filters for HVAC and plumbing markets. Comparable in adjacent categories (water quality in hydronic and potable systems) though not a France-specialist installer brand.
• BWT (Best Water Technology): Large European water-treatment group with broad portfolio including heating-circuit protection, inhibitors, and filters via its Cillit sub-brand. Comparable to Coroxyl in product categories but operates at multi-country, multi-segment scale far beyond a French-only specialist.

Regional players

• Calorstat / Calmag: UK-focused water-treatment specialist supplying chemicals, filters, and dosing equipment for heating, cooling, and process water applications. Operates in a parallel UK installer channel with overlapping chemistry and filtration offerings relevant to Coroxyl's positioning.

Others

• Spirotech: Netherlands-based manufacturer of Spiro-branded magnetic sludge separators, air separators, and hydraulic distributors — the same product family Coroxyl distributes in France as SpiroTrap, SpiroVent, SpiroCombi, and SpiroCross. Functions as a key upstream supplier/partner rather than a direct downstream competitor.
