We have had a great day at Ny Plast where we joined in on the production start up of the HeatSnagger. We made some final adjustments on the drain pipe. On request from several plumbers, we have changed it to a coupling in stead of just a plain 40mm pipe. This will reduce installation time and …
From the lab: Using the setup described in one of the previous news items, we have carried out performance measurements on one of our HeatSnagger prototypes. This was done for both unbalanced and balanced setup, and for different flow rates. (For an explanation of the difference between balanced and unbalanced, please refer to our page …

In his hands he is holding the top piston mold that is needed to help push the heated plastic sheet into the bottom mold prior to applying vacuum suction to it. With the …
The 3D model is now refined as far as we can before actually making the product. It consists of two main parts: a plastic enclosure and a copper pipe unit. The Norwegian company Ny Plast will be making the mold and do the actual vacuum forming for the meandering canal structure where the drain water …
