Miniature tube-in-tube heat exchangers
  These tube-in-tube sample-cooler heat exchangers are geared for applications involving high pressure, low flow and high differential temperatures. All models are made of Type 316L stainless steel with seamless tubes, and feature all-welded construction. Three standard models range in sizes from 0.50-in. to 1.00-in. outer tube dia., and from 0.25-in. to 0.50-in. inner tube diameters.
