Hero Innovations

The semi-enclosed industrial formed steel cover design provides enduring weather protection to the entire machine and importantly its critical working components in the harsh elements due to the unforgiving outdoor working conditions.

Industry first customisable modular build with precision heavy gauge, steel chassis. Versatility for almost any mounting arrangement you can imagine.

Centralised Control
Front facing and panel mounted controls for easy accessibility to all controls and adjustment components that ensure that equipment delivers correctly and to adapt to your jetting job at hand in order to maximise blockage clearing efficiency, effectiveness and operator friendliness.
