Servicing a wide range of
industries with urgent and
standard deliveries, CFT
Services handles more than
500 pallets a day. With
products ranging from pet
food to soap and white goods,
its warehouse is operational
24/7 and 362 days a year.

The constant movement of
cartons and pallets was having
a negative effect. Dusty
freight was considered
unacceptable, so long
standing freight would often
have to be cleaned before
shipping. The company was
also concerned with the level
of airborne dust, so contacted
Zehnder for a survey.

Initial tests confirmed dust
concentration levels were
higher than advised by the
World Health Organisation.

A bespoke solution to meet
the site requirements was
proposed and the installation
of one E12000 and three
E3000 ceiling mounted
Zehnder Clean Air Solutions
units followed. Simple to
install, the units were mounted
in the warehouse without
disruption to operations.

Zehnder units feature a
Flimmer filter and function
like a continuous vacuum
cleaner, filtering dust from
the air. The filter consists of
thousands of electro-statically
charged, fine polypropylene
fibres which attract and catch
the dust. This provides a high
level of dust and particulate
removal while maintaining
the clean air delivery rate. The
large surface area prevents
clogging, frequent filter
changes and pressure loss.

The warehouse was retested
after three months.

There had been an overall
reduction in the level of dust
particulate of 60%. Further
reductions are expected.
