A few weeks ago I was contacted by a mechanical contractor in Bahrain about a needed Cabinet Cooler. Their customer had an existing unit in place and needed two more for similar applications. As with any Cabinet Cooler need, we needed to start with an accurate understanding of the heat load involved, to make sure we recommend the proper model number.
So, we used the Cabinet Cooler Sizing Guide to gather the required information and calculate the heat load of the application. After using this information to calculate a heat load of 426 BTU/hr. (~125W), we confirmed that the existing model 4308-240 will be the correct fit for the additional cabinets as well.
The existing Cabinet Cooler has been in operation for several years without any required maintenance or upkeep. Clean compressed air, achieved with a simple 5 micron water/dirt filter separator, is supplied to the unit and nothing but clean cold air is fed into the cabinet. Relative humidity is regulated by the Cabinet Cooler to 45% resulting in stable temperatures and humidity for the electronics inside the enclosure.
This application is an excellent example of the durability of EXAIR products. With proper compressed air supply our products will operate uninterrupted and at proper performance for years. If you’re in need of a durable solution for an electrical enclosure, contact an EXAIR Application Engineer.
