The temperature diagram shows the expected temperature rise. Due to tolerances of production the shown temperatures can vary by ± 15 %. | Pressure ranges
- High pressure range, 20 – 500 bar
Designed for connection to a high pressure pump. Thus the combination becomes a fully functioning hot high pressure cleaner.
(Attention: This is available only in combination with 3/8“- heating coils !) - Low pressure range, 4 – 20 bar
Designet for connection to a water pipe or to a corresponding centrifugal pump. Thus a powerful flow heater is at your disposal. Minimum flow pressure 4 bar.
(Attention: This is available only in combination with 1/2“- heating coils !)
