ebm-papst has announced the release of new members of AxiCool - the axial fan family for evaporators.
The new sizes 500, 630 and 800 were designed with high-performance evaporators and air coolers for the commercial and industrial cooling sectors in mind.
They are ideal for use in large cold storage facilities and the refrigerated warehouses and production rooms used in the food processing and food industries. Once again, ebm-papst went with the system approach when developing the new AxiCool fans.
All of the individual fan components are perfectly matched, enabling them to achieve maximum benefits when it comes to efficiency, output and noise. The result is an energy efficient plug & play unit with low noise generation that is ready to install.
As the heat exchangers become more and more iced over, fans must frequently work at a higher back pressure. This in turn, reduces the fan’s efficiency, and that of the entire refrigerating plant.
However, the new AxiCool series enables efficient cooling despite this and its integrated diffuser and discharge vane combination increases efficiency by over 30 per cent. This allows the air performance to increase by up to 12 per cent while reducing noise by up to 3 dB(A).
The efficiency-boosting discharge vane is integrated in all AxiCool variants. A cable provides easy, standard connection. An optional terminal box also enables a heating tape to be connected, rounding out the product line. The heating tape can be retrofitted very easily when needed.
All sizes are available in both the high-end variant with a fan housing cover and the standard variant without a fan housing cover.
The fan housing cover offers an advantage when the hygiene requirements are rigorous, since its smooth surfaces attract fewer contaminants and are easier to clean. In addition, a defrost bag can easily be attached to the exterior of the fan housing cover.
All variants are engineered for operation down to 40 °C as standard, and with degree of protection IP55, they are extremely
durable. The AxiCool series is very compact thanks to its external rotor fan design, enabling compact designs for the evaporator units in which it is installed.
The new fans will be available in all sizes as 1 phase and 3 phase AC variants and with efficient GreenTech EC technology in Winter 2016.
Sustainable design
When designing and manufacturing this energy-saving fan for evaporators, the emphasis was on sustainability and the preservation of resources.
Less material means using less energy in manufacturing, which is why this energy-saving fan was designed as a complete unit. A single solution comprising individual components, this integral approach has achieved greater efficiency.
Compared to the more traditional internal rotor motor designs, the amount of steel and copper required has also been halved. The reason behind this improvement in efficiency is the GreenTech EC motor, as well as the one-piece impeller using the established HyBlade technology with profiled blade geometry and winglets.
The EC motor ensures that 30 per cent less energy is consumed than average evaporator fans with traditional AC motors, while single brackets make assembly relatively easy thanks to the flexibility of the mounting holes.
The design allows the customer to retain his existing guard grille design and there is no need to disassemble the evaporator unit even when retrofitting.
The external rotor design has made the energy-saving fan extremely compact, translating into a very low mounting depth while the GreenTech EC motor meets IP54 requirements.
