FLOW FUN­NELS

The flow funnel, a stream­lined inlet and outlet con­nec­tion for hea­ting appa­ratus, is made of seam­less tubes. The half-pipe coil con­nec­tion cor­re­sponds to the design to DIN 28127 in terms of its dimen­sions and scope of appli­ca­tion, and the flow funnel ensures a stream­lined, uni­form tem­pe­ra­ture con­trol wit­hout turbulences.
