Industry Heating Hoses
250 °C
H 800 Special
Heating hose system for co-extrusion for the
plastics industry
Will stand very high temperature and pressure strain.
Series H 800 heating hose systems combined with the series T 3 PTFE
pressure hose are particularly suitable as connection hoses between
a co-extruder and a tool. Rigid connections and a multiplicity of
connection elements are eliminated, which would normally need
to be individually heated, insulated and controlled. The fl exible
connection considerably simplifi es tool change and maintenance.
The heating system can be easily fi tted in your installation..
