Cavitation needn’t cause aggravation
Cavitation is usually bad news for any pumping system and, if left unchecked, it can wreak havoc with impellers and other components. However, modern VSDs offer an easy, low-cost method to detect and prevent it, as ABB’s Andrew Bould explains.
Using VSDs outdoors? Avoid IP ratings you don’t need
HVAC contractors and consultants sometimes specify IP ratings of IP65 or higher for variable-speed drives used outdoors, but a high IP rating is not the same as “weatherproof”, as ABB’s Carl Turbitt explains.
How to dimension a variable-speed drive
ABB’s Liam Blackshaw offers advice on how to dimension a variable-speed drive correctly to suit the application.
Energy saving: time to return to the basics?
ABB’s Steve Hughes discovers that the energy-saving benefits of variable-speed drives are still not widely understood.
Where is fieldbus heading for drives?
Fieldbuses give variable-speed drives the ability to control processes rapidly and accurately, while accessing data to determine how applications are performing. ABB’s Liam Blackshaw offers some insights into fieldbus developments for VSDs.
What you need to know about SECR
