Sealed Enclosure Cooling
ACT’s enclosure cooling products effectively dissipate heat from sealed electrical and electronic enclosures operating in indoor, outdoor and other types of environments. These products are applicable in diverse industries including Industrial Automation, Food Processing, Chemical, Petrochemical, Wastewater Treatment, and Telecommunications. ACT offers a high level of technical support to automation & control systems integrators and OEM’s through our website selection tools, online ordering and direct field support from our factory and local technical representatives.
Our products incorporate many advanced innovations in heat transfer (e.g. air impingement, embedded heat pipes, etc.) and manufacturing (e.g. zipper fins, modularity, etc.). These patent-pending designs often result in significantly improved performance/cost and performance/volume ratios.
Our products comply with UL Recognition and UL Listing testing for the Heat Sink Cooler (HSC) and Heat Pipe Cooler (HPC) series products. ACT’s sealed enclosure coolers are used to dissipate heat generated inside enclosures or cabinets that house and protect electrical/electronic equipment from harmful environments.
The 115VAC units received a UL listing mark. All other voltage versions (230VAC, 12VDC, 24VDC, and 48VDC) are UR Rated/UL Recognized. These approvals are required by OEM’s and Systems Integrators, which are required to follow the UL 508 Standard for Industrial Control Panels.
In addition to achieving UL Certification, the products successfully passed NEMA rating tests. ACT’s sealed enclosure coolers meet UL 50E waterproof testing that qualifies the products to be used in NEMA 12, 3R, 4, and 4X designated applications.
ACT’s Sealed Enclosure Coolers for NEMA 12 cabinets are typically used indoors and provide protection against drips, dust and falling dirt. NEMA 3R coolers are typically used in outdoor applications that will be exposed to rain. And, NEMA 4 and 4X coolers are typically used indoors or outdoors and must be water tight under intense wash down/ spray down usage. The NEMA 4X version, while similar to NEMA 4, is further ruggedized with 316 stainless steel covers and epoxy coated fins for enhanced corrosion protection. Sealed enclosure coolers are required to efficiently transfer heat from the inside cabinet space to the outside environment while maintaining the mounting seal.
We currently offer standard products in three series: The HSC series offer minimum intrusion into the enclosure and some of the best performance/cost ratios; the HPC series are optimized for high performance/volume ratios and often require a smaller opening footprint on the enclosure wall; and the LNC series are particularly useful in applications where noises from the coolers need to be minimized. An Online Selection Tool is available to help select from these standard products to meet user specified requirements. An Online Ordering System is available for buyers to efficiently place orders and track shipments.
For those customers having unique needs beyond the scope of our standard products, our highly experienced engineers stand ready to discuss the requirements and potentially provide a custom solution to meet the requirements. Please contact us by phone, email or the online inquiry form that are provided on each of the web pages.
