Common Applications
Heat Exchangers & Custom Enclosures
Siwa’s wall fin heat excahngers are the most efficient perimeter heating elements in North America. Their high fin density, corrugated aluminum fins & multiple passes around the fins allow the low water temperature to take it’s time in exchanging the heat with the air.
Using tested data, Siwa’s engineering team can design the overall dimensions of the enclosure. To clarify, this will be done by selecting the suitable heating element to achieve the required output for the space given the dimensional restrictions while minimizing pressure drops.
Our custom enclosure manufacturing & design team have 40+ years of experience in manufacturing custom enclosures for perimeter heating, fan coils & PTACs. The units can be manufactured to any shape, color, finish and design with ease. Let’s start the discussions now.
