Isolation devices
Isolation device (breathing apparatus) for remaining in dangerous at-
mospheres and for rescue operations.
Isolation devices
Isolation devices for self-rescue (self-contained open-circuit com-
pressed air breathing apparatus and regenerative devices) for re-
maining in channels and for first supply of persons injured
Rescue harness
Rescue harness or safety clothing with sewn-in neck eyelet. During
the rescue operation, the rescue rope is attached to the neck eyelet.
Lifting the injured person is carried out, e.g. By means of a rescue lift-
ing device with automatic load backstop.
Suitable work clothing
Closed work clothing protects against contamination of skin and pos-
sible infections. Visually noticeable work clothing should make the
employees more visible for road users.
Suitable shoes
The safety shoes should, in particular, offer good support as well as

The enz® standard rotating nozzles stand out because of their versatility. These rotat-
ing nozzles are available in five different jet angle variants. The two drive jets and the
two brake jets keep the rotational speed constant.
The application range for the enz® standard rotating nozzles is entwined with the
selection of the RGS, HRH, HRV, KBR, and KBRV jet angle variants. This is described in
more detail in the sections below.

Introduction
enz® RGS nozzles are equipped with four 75°radial jets for pipe cleaning and three
thrust jets move the nozzle forward, which at the same time flush away the loosened
residues. Pipes of all sorts are fully cleaned, even if they have lateral junctions.
The rotating part of the enz® RGS nozzle moves at a limited speed. These water jets hit
the pipe wall directly with great impact, resulting in excellent cleaning capacity.
Application range
•Drain cleaning
•Lateral junction cleaning
•Removal of stubborn deposits

Introduction
enz® semi-radial rotating nozzles with 45° cutting jets provide the cleaning effect and
simultaneously thrust the nozzle forward; this means rotation and thrust in one func-
tion This minimizes water consumption. However, the tool can also be equipped to
operate with thrust jets if there is enough water to do so.
Application range
•Pipe cleaning for CCTV video recordings
•Remove semi-hard limescale and cement slurry
•Remove roots of up to Ø5 mm

Introduction
enz® HRV nozzles with four 45° jets impacting forward onto the pipe wall, a front jet
(if requested) and three rear thrust jets work like a corkscrew to penetrate a clogged
pipe. As a result, the deposits are broken up, removed by the semi-radial nozzle’s rotor
and pushed forward. The thrust jets produce the forward motion.
Application range
•Flushing out steel pipes after pipe-jacking
•Flushing of the pipes from the building toward the main line
•Removal of ice in manholes and pipes
