HVAC/R plays a vital role in commercial buildings and industrial processes. HVAC systems must provide precise and reliable cooling and air circulation. Regardless of whether it is smaller heat pumps, larger cooling compressors, or advanced ventilation for power plants, warehouses or production companies.

These are often complicated and customised constructions with extensive documentation requirements and technical specifications that must be met. Varying atmospheric conditions, vibrations as well as noise and energy levels must also be factored into the equation.

Therefore, the HVAC industry has a strong focus on operational reliability and energy efficiency. This requires high-quality products and suppliers with deep expert knowledge.

Typical applications

Electric motors play a vital role in HVAC/R applications. They are used in applications such as pumps, compressors and axial and centrifugal fans.

Hoyer's motors can be used for a wide variety of HVAC and refrigeration applications. For example fans, pumps, compressors and heat exchangers. The motors allow precise control using frequency converters and can be designed to meet exact requirements for noise, compactness, energy efficiency and operational reliability.

Hoyer has extensive experience in supplying custom-made motors to several market-leading suppliers at the European market and has long-term cooperation with leading global OEM manufacturers in HVAC and refrigeration. Therefore, we can always deliver the necessary documentation and offer close sparring in the design phase.
