The photo above shows a stainless steel Cabinet at left which has been installed near to a steam exhaust (within 1 meter) in a beverage manufacturing plant.
Inside the panel is a 150 mm diameter fan which is pulling in an air and steam mixture which is causing the temperature inside the cabinet to climb to unacceptable levels. The result is that the motor drives located inside the panel are failing, causing a tremendous cost for replacement and downtime.
Our local distributor worked with the customer to acquire the necessary data for us to calculate heat load within the panel. We determined the customer needed our model HT4880SS-240 Cabinet Cooler System to keep their internal panel temperature at a more reasonable level, year round, even in their worst case scenario with constant steam exhaust in the area.
One key component to success in this application will be removal of the fan and covering of the vent that it once occupied in order to keep the steam from being drawn into the inside of the panel. Historically, fans have been the go to strategy for keeping panels like this cool. However, in this situation, as in many others, the fans pull in un-wanted contamination. There isn’t any filter that can keep steam from getting inside and causing all sorts of problems with condensate forming on internal components, thus promoting corrosion and heat related failures.
The Cabinet Cooler System will provide a filtered, and dry source of cooling airflow which will produce a slight positive purge pressure on the panel to keep such harmful outside atmospheres from entering into the panel. This assures, long life for the panel components and much less hassle and problems associated with heat related failures.
