Benefits - Thermal conductivity

[Translate to english:] VENTAFLEX-Rohr

Outstanding insulation value - hardly any loss
In this manner, with VENTAFLEX you can distribute both heat and cold as required as well as efficiently and therefore in a very environmentally friendly manner.

[Translate to english:] Herkömmliches Rohr

high losses

 

Example transmission thermal conductivity:

Diameter: DN500/600
Insulation: 50 mm
Area: 18.84 m²
Line length: 10 m
Temperature difference: 30 K                                                                                
Heat transfer coefficient:
Ventaflex 0.022 W/mK
WFR wool 0.038 W/mK
WFR Armaflex 0.040 W/mK                                                                                    
Heat loss =
heat transfer coefficient x area x temperature difference
                               Material thickness

Folded spiral-seam tube with closed-cell
elastomer panel coating 453 W
Folded spiral-seam with insulating wool mat 430 W
VENTAFLEX Pipe system 249 W
