CUSTOMISED FORCED VENTILATION UNITS F
or over 20 years WISTRO Elektro-Mechanik has been supplying a wide range of customers with forced ventilation units for variable speed motors. WISTRO has worked continuously to adapt itself to market conditions and today offers its customers a comprehensive range of external fan units to meet almost every need. In addition to its standard design with a wide voltage application range and high degree of protection, it offers variations with direct current power supply, -40°C variants, units for explosion-proof motors and servo motors. The size spectrum ranges from 63 to 560. For two years, customised casing parts or entire cases have been manufactured inde-
IL-Servo External Fan Series
pendently in the company’s newly integrated sheet metal manufacturing facilities. Product development is carried out in advance in cooperation with the customer. Technical specifications such as air pressure, airflow or noise emissions can be documented and reproduced with up-to-date equipment such as volume flow measurement facilities (up to 30,000m³/h at 2,000Pa) noise measuring and other equipment. The aforementioned options are not only available for in-house development but are also offered to customers and third parties as an additional service. WISTRO will soon be introducing its new advanced internal rotor series, initially in sizes of 132 and 160 (and thus also 180 and IL-Standard External Fan Series
200/2-pole). In the future, well-established and more advanced features will work to complement each other in the ILI series. NEW: The terminal box ends with the b-side bearing shield of the forced ventilation unit and can be turned by 90° thanks to its new square shape. The new plug arrangement results in a shorter structural dimension. Both sizes will also be available in 400/690V versions, whilst the 160 size is now also suitable for 1~ 60Hz operation. The air intake grill is flow optimised. The inner suction room will be used in the same way as before, which allows for installation against surfaces and thus leads to shorter installation dimensions. Of course, the new products also fulfil the ErP directive, valid from 2015. www.wistro.com n
