Watlow, an industry leader in the design and manufacture of complete thermal systems recently announced that it achieved UL 499 and CAN/CSA C22.2 No. 72-10 component recognition certifications on its FLUENT in-line heater.

UL® 499 is the Underwriter’s Laboratories, Inc.’s (UL®) Standard for Electric Heating Appliances, and specifies a series of electrical standards, temperature ratings, failure states, etc. to which a product must comply. Achieving the Standard is acceptance that a component meets safety requirements for electricity and fire. The Standard covers heating appliances rated at 600 volts or less, and have an electrical power rating of 15 kilowatts or less per steam generating vessel.

CSA is the Canadian Standards Association and its requirements are similar to UL’s requirements.

“Completing UL® and CSA approval on the FLUENT heater was the next critical step in the development of the FLUENT product platform,” said Andy Selvy, chief system designer. “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.”

The FLUENT is a high watt density, low mass heater that enables on demand heating with an ultra-fast response, leading to higher system performance. The standard construction includes an internal baffle to promote turbulent flow and high efficiency, a fast responding, high watt density layered heater circuit, low profile axial lead exit and an internal thermocouple for high limit control. Powered by Watlow’s patented thermal spray technology, FLUENT makes use of its entire surface to produce heat, which optimizes heat transfer and temperature uniformity.

Watlow is currently offering standard sizes ranging from 250 to 4,000 watts, with several designs available for quick delivery.
