Fans in refrigerated and deep-freeze cabinets are operated almost continuously, so they offer especially large potential energy savings. The proven energy-saving fan from ebm-papst
is now available with a diagonal impeller for especially tight spaces in the rear walls of refrigerated display cases.
Ideal for tight spaces
The axial fans
from ebm-papst are designed for installation beneath the shelves in refrigerated and deep-freeze cabinets. The new diagonal fans, on the other hand, are intended for installation in the rear walls of refrigerated display cases. There is only very limited space for installation there, but with its very flat design, the diagonal fan fits in the narrow gap perfectly and conveys the air in spite of the relatively high back pressure.
The new diagonal fan features specially 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 and means high reliability for the operator. The entire, fully harmonized functional unit also features impressively simple plug & play installation and commissioning.
Use in ceiling air coolers
The energy-saving fan with diagonal impeller 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 flat design and high pressure insensitivity are additional pluses for this application. Placing a FlowGrid air inlet grill on the intake side can reduce noise emission further. The fan is available now in sizes 200 and 250.
