new Hammer
Jet gas turbine is
lightweight and
flexible – it can
be handheld or on
wheels for drying,
cleaning and
heating tasks
A clean and dry surface is
paramount for various
industries within road,
runway and bridge
construction. Gas turbines are the
unique solution for the quick and
easy surface preparation of tarmac
and concrete, before crack repair
or line marking can commence.
Bridge and paving contractors
need to ensure extremely low
moisture in the surfaces prior to
paving or waterproofing. ATT’s
product line with surface dryers
and cleaners of various sizes is the
ideal equipment for drying and
cleaning surfaces before paving,
waterproofing, crack repair, joint
sealing or surface applications such
as line markings.
In addition, tape removal is made
easy by utilising the heat and focused
airflow to disintegrate the adhesion
from the surfaces. With the ability to
dry and clean surfaces as wide as

120cm at a speed of up to 6km per
hour (depending on product, surface/
weather conditions and nozzle
width), the latest turbines alongside
smart electronic technologies from
Danfoss help to maintain day-to-day
business, even in weather conditions
that would normally stop operations.
The products
ATT offers up the Zirocco-M100
(drying widths up to 120cm), the
Zirocco-M50 (up to 30cm) and the
Hammer Jet (up to 20cm).
The Ziroccos are built on a
well-proven concept, with the
recent introduction of a smaller
gas turbine in the entry-level model
Zirocco-M50 for lower noise and fuel
consumption, enabling effective jet
dryer operation in cities and locations
where noise is a factor.
The Hammer Jet is a new,
innovative and mobile device that
weighs just 16kg. This means it can
be utilized handheld with a harness,
or on wheels for smaller drying,
cleaning and heating tasks within
line marking, crack repair, joint
sealing and roof felt applications,
as well as railroad switch de-icing.
All the products have been
designed to bring new capabilities
to the line marking and surface
treatment sector. The self-contained
machines use world-leading gas
