Watlow (St. Louis) recently announced that it has received UL 499 and CAN/CSA C22.2 No. 72-10 certifications for its Fluent in-line heaters.

The Fluent in-line heaters are designed for a number of applications including hemodialysis fluid heating, ink preheating systems, semiconductor purge gas heating and on demand fluid heating. The heater’s small profile allows it to reduce the overall size of the system it is installed in while lowering the cost of the system. It features customizable heating profiles with distributed wattage. Fluent’s high watt density and low mass heater allows for a fast response time and efficient heat transfer.

UL 499 certification is administered from Underwriter’s Laboratories and is the standard for electric heating appliances. It outlines a series of electrical standards, temperature ratings and failure states that a product has to meet. The certification covers heating appliances that are rated at 600 volts or less and have an electrical power rating of 15 kW or less per steam generating vessel.

CSA requirements are laid out by the Canadian Standards Association. Its standards are similar to Underwriter’s Laboratories’s.

“Completing UL and CSA approval on the Fluent heater was the next critical step in the development of the Fluent product platform,” Andy Selvy, chief system designer, said. “Customer safety is of utmost importance to us, so achievement of all necessary safety certifications ensures that our products will perform safely and accurately in our customer’s application.”
