BELPARTS Group NV

What BELPARTS Group NV does

BELPARTS Group NV is a Belgian privately-held manufacturer of HVAC (heating, ventilation, and air conditioning) components, founded in 1989 and headquartered in Rotselaar, Belgium, with regional offices in Gorinchem (Netherlands) and Roissy CDG (France). The company sells to HVAC installers, consulting engineers, building owners and managers, and building automation system integrators across Europe and, via an international network, into other global markets including Asia (exemplified by participation in the CRH 2024 trade show in Beijing).

The product portfolio is organized under two brands. The dynamx™ line comprises self-balancing, dynamic flow control valves (DXN6 6-way, DXMB_B 2-way, DXMB4_C Quattro 4-way) that combine flow control, balancing, shut-off, and energy monitoring in a single device, with wireless configuration via the dxLink21 mobile app and MODBUS/BACnet integration into building management systems. The energetx™ line covers conventional HVAC field equipment including PN16 and industrial control valves, butterfly valves, linear and thermoelectric actuators, terminal control valves, sensors (temperature, humidity, CO2, VOC, differential pressure), and thermostats and safety devices. The dynamx™ One has won the iF Design Award and Red Dot Award, and the underlying technology is protected by a granted European patent.

The business model is hardware-led: Belparts manufactures and sells physical HVAC components to professional buyers through direct sales offices in its three core markets and through an international distribution network for other regions. Pricing is not publicly disclosed and customers are directed to contact the company for quotes. An ancillary revenue stream comes from technical support services delivered through an Atlassian-powered support portal for commissioning and operational issues with dynamx™ and energetx™ products. Marketing is conducted via a multilingual website (Dutch, English, French), product datasheets and catalogs, a newsletter, direct regional contact channels, and industry trade shows.

Core offering

BELPARTS Group NV develops and manufactures HVAC components for automated building climate control, including self-balancing flow control valves (dynamx™), conventional control valves, butterfly valves, industrial valves, actuators, sensors, and thermostats (energetx™). The flagship dynamx™ line combines dynamic flow control, real-time monitoring, and wireless configuration via the dxLink21 app, with MODBUS/BACnet integration for building management systems. Products are sold primarily to HVAC installers, engineers, building managers, and building automation integrators across Europe and internationally.

Product overview

BELPARTS Group NV is a Belgian manufacturer of HVAC (Heating, Ventilation, and Air Conditioning) components with over 35 years of experience. The company's product portfolio centers on two main brands: dynamx™ (intelligent flow control valves with dynamic balancing and wireless configuration capabilities) and energetx™ (conventional HVAC field equipment including control valves, actuators, butterfly valves, terminal control valves, sensors, and security/thermostat products). The dynamx brand represents the company's flagship innovation with smart, self-balancing flow control valves that integrate with building management systems via MODBUS/BACnet and can be configured through a dedicated mobile app (dxLink21). The energetx brand provides complementary conventional HVAC components including PN16 control valves, industrial control valves, actuators, sensors, terminal control valves, and safety devices. Together, these products serve both hydronic (water-side) and air-side HVAC applications for commercial and residential buildings.
