The environmental policy of ALTO
ALTO has made it a natural part of the concept
of the company to reduce the impact on our envi-
ronment as much as possible. This plan is effected
through a constant development in all branches of
the company so that the greatest number of ele-
ments in our high pressure washers affects the
environment to a minimum.
This product too is characterized by the attitude
of ALTO towards our environment.
For the production of this high pressure washer
the latest production technique within a cleaner
technology has been applied. The consumption of
unnecessary subsidiary materials has been mini-
mized and during the final test of the product the
test water is recycled.
