THE BEST OF BOTH WORLDS
The HMR EVO from Casals Ventilación is the helical-centrifugal tubular fan designed to offer the best of both worlds: greater energy efficiency and less noise.
If your installation has a high pressure loss, the HMR EVO is the ideal solution for transporting air efficiently and quietly.
HIGH PRESSURE LEVELS AT LOWER SPEED
Although its shape is similar to a tubular axial fan, the HMR EVO stands out for its performance as a medium-pressure centrifugal fan. This means that it can offer high pressure levels, comparable to those of an axial fan, but operating at half the revolutions per minute (rpm), which reduces wear and improves durability.
MORE PERFORMANCE AND LESS NOISE
Designed to perform at its best in high-pressure areas, the HMR EVO is 30% more efficient than a axial fan such as the HMA, and also produces up to 30% less noise, making it the preferred choice for spaces where acoustic comfort is key.
Highlights of HMR EVO:
-
Up to 1,200 Pa of pressure compared to the 700 Pa of an axial fan like the HMA, doubling the optimal working pressure in demanding areas.
-
Silent operation, especially at medium and high pressure levels.
-
High efficiency impeller with built-in diffuser, which eliminates the need to use a scroll or spiral casing to obtain performance.
Why is so important a diffuser in a centrifugal fan?
The HMR EVO’s built-in diffuser optimises airflow, reducing turbulence and improving system efficiency. Thanks to this technology, the fan can operate more efficiently without the need for a spiral casing, which in addition to saving space, means improved aerodynamic performance, reducing energy consumption and noise.
