Heating and Cooling Supply

Strong on their own, unbeatable together: KSB products are the basis for highly efficient HVAC systems

KSB supplies the right components for use in heating and cooling applications as part of its comprehensive range featuring pumps and valves alongside automation and drive solutions.

When it comes to heating and cooling systems, unique challenges require tailored solutions

Clean air, the right humidity and a comfortable temperature: Properly conditioning a room’s interior climate is the basic prerequisite for the well-being and performance of people and machinery.

Whether family house, office complex or computer centre: Every building is unique and poses specific challenges when planning and implementing optimum heating, ventilation and air-conditioning systems. Effective and efficient HVAC solutions thus require suitable components optimised to work perfectly together.

While challenges may vary depending on the building project, component requirements remain the same. Pumps and valves employed in this sector should work reliably and quietly while offering a long service life.

However, for heating and cooling supply in building services applications, economic efficiency and ecological considerations are just as important as functionality. Here, efficient use of energy is a key topic.

KSB products are the foundation for perfectly matched and highly efficient HVAC systems

KSB is the only supplier on the market to offer a complete range of heating, air-conditioning and ventilation systems comprising pumps and valves alongside automation and drive solutions. This means that customers are sure to find suitable components for their systems with their special requirements.

Optimised to work together, these efficient components cover the requirements of all heating, ventilation and air-conditioning systems – from single-family homes to airports. The result is that KSB products are the foundation for highly efficient HVAC systems whose components are optimised to work perfectly together. A comprehensive range of services rounds off KSB’s portfolio for heating and cooling supply in building services applications available from a single source.

Pumps, valves, drives and automation products: KSB supplies the right components for every application

Thanks to the breadth and depth of its product range, KSB is able to supply the right components for all applications in heating, ventilation and air-conditioning – whether for family homes, high-rise buildings, railway stations or computer centres.

But optimised adaptation to individual conditions requires more than an extensive product portfolio. Years of experience on the market and ground-breaking technology are just as important. KSB offers both: thorough know-how gained through the implementation of numerous projects and innovative solutions developed through continual investment in research and development.

Many KSB pumps for cooling and heating systems can be equipped with high-efficiency drives such as KSB SuPremE and automation solutions such as PumpDrive. These smart products ensure energy-efficient operation of your system, monitor the operating status of your pump and notify you of any necessary service measures in good time.

Operating alone, these high-quality pumps already work reliably and efficiently. But they work even better in an optimally configured system. KSB thus offers the right valves for all pump applications, and these enable hot water, heating, ventilation and air-conditioning systems to be controlled and flow rates matched to demand. The result: increased overall efficiency in your plant and substantial savings in energy consumption. Of course, KSB valves also offer exceptional quality. They work safely and reliably when shutting off and controlling a wide variety of fluids.
