Pick something undersized and your components run hot, slowly degrading until something fails. Oversized, and you've spent more than you needed to and may end up dealing with condensation issues from overcooling. The engineers who get it right aren't guessing; they're working through a defined set of inputs that account for the actual thermal environment of their application. HESCO carries the full nVent Hoffman climate control lineup, which means once the tool tells you what you need, we can get it to you. Hoffman's online [Climate Control Selection Tool](https://www.nvent.com/en-us/hoffman/climate-control-selection-tool) takes the guesswork out of cooling specifications by walking you through your application parameters and returning a list of appropriate products, narrowed from over 1,000 standard configurations down to what actually fits your situation. This article walks through how the tool works, what information you'll need before you use it, and what the outputs mean. The short version: The tool asks you to define your enclosure dimensions, mounting configuration, environment, and heat load. It then recommends closed-loop and open-loop cooling solutions matched to your application. If you know your inputs, the whole process takes under ten minutes, and HESCO can take it from there. ## What the Tool Needs from You The selection tool is organized around two main categories of information: enclosure characteristics and heat load. Getting accurate answers for both is what separates a good recommendation from a generic one. ### Enclosure Characteristics The tool starts with the physical details of your enclosure: ### Heat Load This is where most of the uncertainty lives, and the tool gives you three ways to handle it: You'll also set your target temperature parameters: the maximum allowable outside temperature, the maximum desired inside temperature, and whether you need to account for cold weather operation below 50°F. That last input triggers the heater sizing portion of the recommendation. ## Reading the Results Once you've entered your inputs, the tool returns two categories of recommended products: The tool also displays the total calculated heat load in watts and the projected internal temperature without any cooling, which shows how much work your passive enclosure is doing (or not doing) on its own. ## When the Tool Isn't Enough The selection tool covers the majority of standard applications well. But there are situations where its output is a starting point, not a final answer: ## The Tool Does the Math. HESCO Does the Rest. Run through the tool, note your recommended products, and bring that list to the HESCO team. We stock Hoffman's full climate control lineup and can turn a selection into an order, whether you've got a straightforward spec or something that needs a closer look. If your application falls outside what the standard tool covers, we can help you work through it.
