Spirotech

What Spirotech does

Spirotech BV, founded in 1954 and headquartered in Helmond, Netherlands, is a specialist manufacturer of system water quality solutions for closed-loop HVAC (heating, ventilation, and cooling) installations. Its product family addresses the conditioning, separation, and protection needs of water-based heating and cooling circuits and includes air separators (SpiroVent), dirt and magnetic dirt separators (SpiroTrap), hydraulic balancers (SpiroCross), expansion vessels (SpiroExpand), water treatment products, vacuum deaerators, and heat pump filters (including the 2025 SpiroTrap HPF). The portfolio is built on the company's proprietary SpiroTube technology and its patent-pending MultiMode Swivel mechanism, which together underpin the air- and dirt-separation performance that differentiates the brand in the HVAC component market.

The company generates revenue by designing and manufacturing proprietary hardware components and selling them exclusively through technical wholesalers. Its downstream customer base spans heating and cooling installers, OEM boiler and heat pump manufacturers (where Spirotech components are frequently specified into equipment designs), engineering consultants, and residential end users. With 251–500 employees and distribution coverage spanning Western, Central, and Eastern Europe, the Middle East, and North America, Spirotech operates as a mid-market industrial component supplier anchored in a narrow, technically demanding niche where OEM prescription and a long-tenured wholesale channel constitute the principal sources of demand.

In recent years Spirotech has broadened its addressable market through the SpiroCool line for data center cooling loops, the heat-pump-targeted SpiroTrap HPF, the magnet-equipped SpiroCross Steel series, and the SpiroSelect online specification tool supporting its wholesale partners.
