News & Innovations

Interdisciplinary and transnational

hotset is establishing value-added partnerships in control cabinet
construction For the first time, hotset presented itself at the last Hannover trade fair as an outsourcing partner willing to assume responsibility for entire valueadded chains. The example of hotset America shows how far the technological competences and the international action radius of thermodynamic specialists have since come. For quite some time now, the overseas subsidiary of the company based in Lüdenscheid has already been configuring and installing completely equipped control cabinets for a renowned manufacturer of injection molding machines.

The know-how thus accumulated laid the foundation for a close
cooperation with Siemens, from whom hotset received the “Synergy
Panel Builder Partner” award only a few days ago.

Thin rods for tasks involving heat

Hotset presents its new high-performance heating cartridges in miniature format With a diameter the size of a match head, the new hotrod® HHP 1/8“ (3.1mm) must currently be one of the smallest electrical heating cartridges available on the global market.

Developed for application in,compact devices with limited installation space, this product represents,the ideal solution for the target-oriented temperature control of minimal,quantities of adhesive, lubricants or ink. For special applications, a heating performance of up to 750°C is also possible. Manufacturers in medical technology and microdosage technology have already expressed their interest in this innovation by hotset.
