As electrical/automation and control systems components become more compact and complex the internal enclosure heat loads are increasing. PLC’s, starters and drives are some of the major generators of heat in an enclosure. There are many challenges in the way we choose to keep the enclosures cool. ACT has developed a series of heat exchangers and air conditioners that are environmentally sealed to cool and protect the internal cabinet components from water, airborne chemical, and particulate contaminants.

Watch now for an in-depth discussion on sealed enclosure cooling technology options. We will discuss above and below ambient cooling technologies, how they are selected and installed. We will conduct live demonstrations of each ACT sealed enclosure cooling family so you can compare sizes and options. We will encourage questions and discussion as if you were with us, in person, at a trade show!




Hello, thanks for joining us today, just a few things to get us started. You can ask questions in the question box to be answered at the end of the webinar. If you have any technical questions,



you can submit them in the chat box. You can also make your webcam screen larger by dragging down on the grey bar in the top of the screen, located underneath of the webcam screen.



We’re going to jump right in today. Mark Stevens, our South East territory manager is going to get us started!



Hello everyone and thanks for tuning in today, we’re going to make this event a tradeshow type of event



where we’re going to talk about the products we’re going to give you some ideas on how their used, some of their capabilities.



We’re going to go through our enclosure coolers that are our heat exchangers, and then we will also talk about our air conditioning product lines



and Devin Pellicone is going to share that. He’s our lead engineer working on these products.



So between he and I, we should be able to answer any of your questions and we’ll give you a good basis for what these products do.



Our enclosure cooler line was originally developed to bring something onto the market that was very unique.



And the fact that most of you out there probably have familiarity with fan coolers, where you’re drawing air from the outside of the cabinet, taking that cooler air from the outside of the cabinet, circulating it through and then discharging it.



Can have problems there, could be dust, There could be chemicals. If you’re in a chicken plant, you could be brining in  Pneumonia, If you’re in a wastewater plant, you could be bringing in hydrogen sulfide fumes and other things that can actually damage Your PLC is your relay’s, your control systems.



So, we wanted to come up with a way that completely sealed the environment from whatever was going on in the outside of the Cabinet, and what’s on the inside of the cabinet, But also introducing a very good cooling technology.



And so, what we’ve designed is our two product ranges. We have our heat pipe coolers here, which I’ll explain in a moment, and then we also have our heat sink coolers. I’ll talk about the differences of these two products.



The heat pipe coolers work with the a ACT heat pipe technology. And what we essentially do is we have a separation barrier here



and these devices are rated at NEMA 4 or they can be rated NEMA 4X because they’re in a 316 stainless steel. And they’re also encoded for corrosion salts sprays and other things.



So the nice part about our heat pipes is they are a very good heat transfer system.



So what we have is a tube and inside of the two there is methanol, and what happens when it’s under vacuum.



So as the hot air flows into here, the actual method all else then comes up to the outer cabinet and condenses and gives off it’s heat.



And the way we do this is with the two fans, and the fans flow counterflow.



So they are able to very effectively cool the inside of the cabinet to the outside of the cabinet.



Now, what we call that is above ambient cooling.



Above ambient cooling means that the inside of the cabinet is running hotter than the outside of the cabinet.



And Devin will talk about sub-ambient cooling where the outside of the cabinet is hotter than the inside of the cabinet.



So, those are two of the application considerations when taking a look at our product.
