VT Serpentine Cores
The construction is called a serpentine but we like to think of Charlie Brown's shirt. These are commonly found in the early 50s and carry on for many many years. The tubes are inline and we can increase the fin density and narrow the distance between tubes to add surface area increase the contact points.
We make to order. There is a nationwide labor shortage. Please allow adequate time for us to build. Build times vary between 15 and 24 weeks at present.
