EC fans energy-saving motor axial fan FlowGrid
Fan and motor manufacturer ebm-papst has launched a compact energy-saving fan for use in the rear walls of refrigerated display cases.

Fans in refrigerated and deep-freeze cabinets are operated almost continuously, so they offer especially large potential energy savings. The energy-saving fan from ebm-papst is now available with a diagonal impeller for tight spaces.
Axial fans are designed for installation beneath the shelves in refrigerated and deep-freeze cabinets. The new diagonal fans are intended for installation in the rear walls of refrigerated display cases. There is only very limited space for installation there, but with its flat design, the diagonal fan fits in the narrow gap  and conveys the air in spite of the relatively high back pressure. 

The new fan features optimized noise and air flow characteristics in the medium pressure range at 65 Pa and 500 m³/h. Additional benefits come with its efficient GreenTech EC motor: higher efficiency than AC fans, compact design, and flexible adjustability via a programming interface or an optional ESM plug-in module. The EC motor’s minimal self-heating results in further energy savings. Its expected lifetime is more than 40,000 hours, which corresponds to approximately 4.5 years of continuous operation. 

The manufacturer says the fan is also suitable for use in ceiling air coolers, for example in small commercial cold storage rooms such as bakeries or butcher shops. The diagonal positioning of the blades redirects the incoming air radially toward the outlet.  The fan is available in sizes 200 and 250.
