Tube axial cooling fans

12 November 2008 Circuit & System Protection

To ensure the reliability of its range of tube axial cooling fans, Bi-Sonic has specialised laboratories dedicated to testing product performance. This level of quality assurance has earned the company’s products worldwide qualifications and approvals such as UL, CE, CSA, TUV, ISO 9001:2000, 1323, IP54 and also RoHS compliance.

The range of tests to which products are subjected includes high and low temperature storage, low temperature running, cold-starting and temperature cycling, as well as humidity and vibration. In terms of operational safety, fans must also pass simulation tests such as reverse polarity protection etc.

PHD Power’s stockholding of Bi-Sonic products includes dual ball bearing options, various frame sizes, plastic and metal blade choices. AC and DC versions as well as dual AC voltage fans facilitating 110 and 230 V a.c. applications are available. These dual voltage fans have four lead wires and depending on the connection configuration (indicated on each fan) these units can be connected to either AC voltage.

Several accessories are also stocked locally, including plastic dust filter kits, chrome finger guards etc, all of various sizes as required per application.
