When the system powers up, the recirculating fans in HVAC units come on for three minutes. This gives them time to go through pre-start checks as well as start moving air about the enclosure to get a proper initial temperature reading. We also have recirculating fans in the compartment that also...

Thanks Tom and this is exactly the conversation for which I have been looking! In addition to the PLC, computer, modem, and 120VAC-24VDC power supply putting out heat, there is a heated head pump, a heated filter, and a heated valve. This train is connected with 1/4" stainless tubing with...

I have a call with a powder coating manufacturer tomorrow to see what they have to say about their colors and textures WRT reflectivity in the IR spectrum. Hopefully they will have some answers.

Here are a couple of photos to give you an idea of the compartment. The external photo shows the two main sides exposed to the sun and reflective heat from the gravel pad.

Foam is on all six sides with the foil reflective side against the 20-gauge steel panels, so the compartment is encapsulated in the insulation and completely sealed. For the power consumption, we run the equipment on shore power right at 15A on 120VAC, which does not include the HVAC that is on...

Referring to the attached, the bottom right is an electronics compartment. The external panels are 20GA steel powder coated yellow. There is 1-inch of R-6 foam board insulation on the inside of all external walls. The skid is exposed to ambient heat and direct sunlight when on site. If we...

We do a lot of mechanical engineering work, so am hoping to learn here.
