Air Movement and Heat Recovery

HVAC components

We specialize in the design and production of key air treatment components for air handling units and rooftop units.

How do we operate

Local production and testing. Full production and delivery traceability. Competitive pricing,
fast order fulfillment.

Sustainability

When designing new products, improving existing ones and implementing new processes in our company, we pay great attention to how they will affect our environment.
That is why we choose solutions that will allow us to achieve our business goals while maintaining our social responsibility to the communities that we serve.

Lean Management


It is a system that interconnects all processes taking place in our company. It is a tool that allows for quick exchange of information within our organization, and thus for permanent, quick implementation of new solutions as well as improvement of those already implemented.

Automated & Robotized Production


To ensure full repeatability of the components we produce, we have implemented highly automated production lines with cutting-edge automation solutions.
All this to eliminate the human factor from these production activities, where the key issue is the precision of execution and validation of the correctness of assembly activities.

Where are we located?

We design and manufacture locally… to be as close as possible to our customers and the markets that they operate. So as to fully understand their requirements and follow changes in regulations.

Swiss Rotors Lab

We have installed a certified AMCA test station, where we test the performance and of our fans based on the guidelines of AMCA 210 – the default standard for the most recognized fan certification in the world.

The laboratory of Swiss Rotors Sp. z o.o is accredited with AMCA International as being qualified to conduct tests in accordance with AMCA 210 Fig. 12, Fig. 15.

Fan Performance Reliabioity

Fans are undoubtedly the main energy-consuming component of ventilation systems. Unlike energy recovery systems, the fan is used regardless of the season – practically all the time when the air handling unit or rooftop is running.

Proper and accurate assessment of the performance parameters of the fans we produce is the key to building long-term business relationships with our clients.
