What IMI Hydronic Engineering does

IMI Hydronic Engineering is the Climate Control division of London-listed engineering group IMI plc, specializing in hydronic balancing and control components for HVAC terminal units. The business traces its origin to August Hilmer Andersson's 1897 founding in Ljung, Sweden and was the originator of the world's first manual balancing valve in 1957 through the TA brand. It operates today through three retained heritage brands: IMI TA (balancing, control and actuation), IMI Pneumatex (pressurization and water treatment), and IMI Heimeier (thermostatic control).

The core product portfolio comprises balancing valves, pressure-independent control valves, digitally configurable actuators, precision pressurization systems, and cyclonic dirt/magnetite separators. Proprietary technology centers on EQM (Equal Percentage Modified) flow characteristics embedded in TA-Smart and TA-Modulator valves, enabling combined flow, temperature, and power measurement. Flagship offerings include TA-Smart (2-way control valve with measurement), TA-Modulator (pressure-independent balancing and control), TA-Slider 750 (750 N digitally configurable proportional push-pull actuator), Compresso Connect (precision pressurization for heating up to 12 MW and cooling up to 18 MW), and Zeparo Cyclone Max (DN50-DN300 cyclonic separator). Smart connectivity for modern building management systems is positioned as a growing portfolio layer.

IMI Hydronic Engineering monetizes through B2B hardware sales of proprietary HVAC components to commercial, residential, and industrial building customers, distributed globally via HVAC distributors and wholesalers. Pricing is quote-based and not publicly disclosed, consistent with enterprise-specification sales. With 501-1000 employees, 100K+ completed projects, and 125 years of combined heritage, the division leverages parent IMI plc's corporate infrastructure while serving a horizontal customer base across building HVAC system use cases including retrofits, commissioning, and decarbonization-compliance upgrades.
