Tridan is pleased to introduce our latest development in coil production machinery. The Super Flexpander, Model SFE. After 20 years of proven success with the original Flexpander, Tridan’s innovative design improvements make this new semi-portable expander ideal for the more specialized needs of today’s coil manufacturers. An upscale drive system and new clamping technology allow the Super Flexpander to expand larger diameter tubes, more exotic materials and heavier wall thicknesses required for many of the new refrigerants. The Super Flexpander can also expand some alloys of stainless steel, aluminum/brass, mild steel and cupro-nickel.
