Commercial HVAC Solutions
IMI solutions help create comfortable, controllable indoor climates and efficient system operation in commercial buildings.
What Are Commercial HVAC Solutions?
Commercial HVAC hydronic solutions can help create and maintain suitable indoor conditions across buildings with multiple zones, changing loads and diverse users. They bring together:
- Heating and cooling: Hydronic circuits distribute thermal energy from sources such as boilers, chillers and heat pumps to terminal units throughout the building.
- Hydronic control and connectivity: Valves, actuators, sensors and compatible digital interfaces regulate flow and provide useful operating data.
- System design and commissioning: Correct sizing, balancing and verification help each terminal unit receive its design flow under full- and part-load conditions.
- Pressurisation and water quality: Correctly selected and maintained pressure-control, air-removal and dirt-separation solutions can help support system performance and reduce exposure of components to conditions associated with air and debris.
- Monitoring and optimisation: Measured system data can reveal unstable control, excess flow and other opportunities for operational improvement.
Commercial HVAC Solutions by IMI
About hydronic balancingHydronic balancing and control
Manual, automatic and pressure-independent solutions can help maintain specified flow across variable-load heating and cooling systems, supporting controllability and comfort when correctly selected, installed and commissioned.
About smart controlSmart control and actuation
Depending on the selected solution, connected valves and configurable actuators can provide control functionality and access to flow, temperature, power and diagnostic data.
About pressure maintenancePressure maintenance
Static and compressor- or pump-based pressurisation solutions help keep closed hydronic systems within their intended pressure range.
More on air and dirt separationAir and dirt separation
Degassing and separation solutions are designed to remove air, dirt and magnetite from hydronic systems. Performance depends on correct product selection, sizing, installation, operation and maintenance.
More on thermostatic room controlThermostatic room control
Room and terminal controls help occupants achieve comfortable temperatures while supporting controlled heat delivery.
Design, selection and commissioning support
Hydronic expertise, selection tools and measurement instruments can support designers and installers in sizing, setting and verifying systems throughout the project lifecycle.
Commercial HVAC Solutions by Building Type
Every commercial building has a different load profile, operating schedule and comfort requirement. A system approach helps match hydronic performance to the way each building is designed and used.
Office buildings
Variable occupancy and diverse zones demand responsive control. Balanced distribution and terminal-unit control help maintain comfort across meeting rooms, open-plan areas and perimeter zones as loads change. See how we renovated a regional authority office in Czechia.
Retail and shopping centres
Long opening hours, entrances, lighting and changing footfall create fluctuating loads. Stable hydronic control helps serve individual retail zones without unnecessary overflow. See the improvements we made in a shopping mall in Brazil.
Healthcare facilities
Continuous operation and diverse clinical spaces require reliable, measurable performance. Accurate flow control, pressure stability and clean system water support dependable heating and cooling. More on our healthcare solutions.
Hotels and hospitality
Guest rooms, kitchens, leisure areas and event spaces have different schedules. Zoned control helps deliver comfort where needed while responding to part-load operation. Our success story on the renovation of the Hotel Aleksandar Palace in North Macedonia.
Educational facilities
Classrooms and shared spaces experience sharp occupancy changes. Correct balancing and controllable terminal units help maintain consistent conditions across the campus. Read about our renovation of educational units.
Industrial and manufacturing facilities
Process gains, ventilation loads and comfort areas can create complex demand. Robust control and reliable pressure management support stable operation across mixed-use zones.
Warehouses and distribution centres
Large volumes, high doors and uneven occupancy make zoning critical. Hydronic control can direct capacity to active areas and support temperature stability.
Commercial HVAC Solutions for Your Business Needs
HVAC Systems and Technologies
IMI solutions support the water side of commercial heating and cooling systems, connecting generation equipment to distribution circuits and terminal units:
- Boilers, chillers and heat pumps: Balancing, control and pressurisation solutions help generated heating or cooling reach the system at the required flow and operating conditions.
- Air-handling units and terminal units: Control valves and actuators regulate coil flow in AHUs, fan coils, radiators and other emitters.
- Variable-flow networks: Pressure-independent and differential-pressure control solutions are designed to support controllability as valves open and close, subject to correct selection, installation and commissioning.
- Pressurisation and water-quality systems: Correctly selected and maintained pressure-maintenance, degassing, air-separation and dirt-separation solutions can support system operating conditions and help limit the presence of air and debris.
- Building management integration: Selected smart valves, actuators and pressurisation units can communicate key parameters to compatible building-management systems.
Why Commercial HVAC Requires a Different Approach
Commercial buildings combine larger water volumes, long pipe runs, many terminal units and zones with different schedules. Occupancy, weather and internal gains can change demand throughout the day, so the hydronic system must remain controllable at both design and part load. Poorly distributed flow can leave some zones underserved while others receive excess flow, contributing to comfort complaints and unnecessary pump demand. Commercial systems also need pressure stability, effective air and dirt management, commissioning evidence and interfaces with building-management systems. In hospitals, hotels, offices and other occupied facilities, interventions may need to be planned around operational continuity. Solutions therefore need to be selected as part of a complete system—balancing, control, actuation, pressurisation and water quality—rather than as isolated components, with capacity for future changes in occupancy, plant or zoning.
Our Commercial HVAC Approach: The IMI Way
01 — Assess
Understand the building, load profile, operating priorities and existing hydronic performance using drawings, measurements and stakeholder input.
02 — Design
Size and select balancing, control, actuation, pressurisation and water-quality solutions around the building’s design and part-load requirements.
03 — Install
Support correct installation, configuration, balancing and commissioning so that design intent can be verified in operation.
04 — Integrate
Connect compatible devices to the wider control strategy and make relevant operating parameters available for monitoring and diagnostics.
05 — Maintain
Use accessible settings, measurement points and system data to support planned checks and targeted troubleshooting.
06 — Optimise
Review flow, temperature, pressure and control behaviour to identify practical improvements as use patterns and system requirements evolve.
