Commercial HVAC

With reduced weight and size, COPRA™ system fits multiple wall configurations in locations such as office buildings, hospitals, libraries and other commercial building spaces.

Data Center

COPRA™ easy installation fits new or retrofit projects. The cooling system is compliant with IT industry-wide specifications. Energy and consumption costs are reduced to the lowest feasible level.

Retrofit: Replacing fans with COPRA™ fans pays off

Lower Energy Costs
Less Maintenance
Less Emissions

The new COPRA™ fans maximize efficiency while minimizing required space in your system. Their short motor do not obstruct airflow, while the newly developed aerodynamic impeller design maximizes efficiency at both full and reduced speeds.

Perfect for simple plug-&-play installation in new HVAC systems as well as for the modernization of existing systems, COPRA™ fans can deliver significant cost savings.

The Ideal Plug Fan for Fan Arrays

COPRA™ fans are ideally suited to multiple wall configurations in the form of several fans arranged next to and above each other. COPRA™ fans are the best fit for multiple wall configurations not only because of their compactness in axial length, but also because of their smallest possible diameters with high airflows.

Competitor Fans With External Rotor Motors Vs. COPRA™ Fans

COPRA™ effectiveness exceeds traditional motors in every situation with its system efficiency at part load compared to all other conventional ec motor technology.

Unleash aerodynamic efficiency in an ultra-compact powerhouse! COPRA™ redefines the game with its short axial length, delivering unmatched efficiency for tight installations. Experience top-tier part-load performance, exceptional power density, and impressively quiet operation. This is the one series that fits all, boasting superior geometry and materials.
