You probably walked by many items in a department store that had a UL mark, and not even noticed. What does this mark mean? The Underwriters Laboratories (UL) is a third-party organization that verifies that products are safe for use. They have been around for more than 100 years, and they are very important for checking the design of electrical systems. In order to receive the UL stamp, it has to pass stringent tests for conformance and safety, and they register the items on a database for users to review. EXAIR uses this service for our products. EXAIR stands behind our products with the Underwriters Laboratories recognition. I will go over the products that EXAIR manufacturers and the type of UL marks that we have.
There are three main types of UL marks; UL Listed, UL Recognized, and UL Listed Classified.
UL Listed: All EXAIR Cabinet Coolers are UL Listed! It is important to note that EXAIR was the first to ensure that your electrical panel’s NEMA rating remained when using our Cabinet Cooler Systems. Our products underwent numerous tests and scenarios to verify that an operator will be safe during normal operations. The tests for the Cabinet Cooler Systems included environmental exposure for the given NEMA type along with many other tests. When you place a Cabinet Cooler onto your electrical panel, the degree of protection is not affected. Our Cabinet Cooler Systems come in NEMA 12, NEMA 4, and NEMA 4X. They are designed to keep the electrical components inside cool; stopping unnecessary shutdowns from excessive heat. With the UL listed mark, the Underwriters Laboratories have deemed these products safe for operation throughout the US and Canada per their standards.
UL Recognized: The Gen4 Static Eliminators and Power Supplies are UL Recognized. UL Recognition is most often seen with components, in a form of power supplies or circuit boards, that are used to power other parts. UL Recognition ensures the safety and efficiency of machinery used by operators. In other words, it certifies that a component within a larger instrument meets UL standards. The Gen4 Power Supplies are used to generate ions with our Gen4 Static Eliminators. These ions will remove any type of static that can cause jams, misalignment, and harmful shocks. We offer two types of Power Supplies, a two port and a 4 port, to operate eight different styles of Static Eliminators. And together, you can make sure that your operators are safe when using our products to remove static nuisances.
UL Listed Classified: The UL Classified certification means that the product has been evaluated, tested and passed the test for being safe when installed within classified areas. This includes a large range of hazardous locations which according to OSHA is defined as an explosive atmosphere due to the presence of flammable gases (Class I), combustible dusts (Class II), or ignitable fibers and flyings (Class III). Unlike the Cabinet Coolers above, the HazLoc Cabinet Cooler went through a more stringent test to operate in all classified areas. Used with a purge system, the HazLoc Cabinet Cooler keep the electronics from faulting due to over-temp.
Here are our registration number with UL for you to review:
Cabinet Cooler Systems: E182292
Static Neutralizing Equipment: E138256
Hazardous Locations Cabinet Cooler Systems: E498880
It is widely known that machines are the lifeblood of any business. Taking steps to protect your investment and your operators that use the equipment is essential for long-term success of a company. The UL certification will give you that peace of mind. Lastly, since UL is a third-party service, you can be confident that the UL label is a true sign of safety and longevity within electrical systems. If you would like to discuss more about our UL listed products for removing static or cooling electronics, an Application Engineer at EXAIR will be happy to help you.
