Trust & Dunker turn up the heat
T
wo European flexitank specialists have joined forces to
create what they claim is a benchmark in flexitank heating
systems.
Spain-based Trust Flexitanks, which says it is the only company in
Europe with the ability to produce both monolayer and multilayer
flexitanks in the same factory, boasts a large part of its production
processes as being automated using unique and state of the art
precision engineering, guaranteeing a final product of the highest
quality.
Bremen, Germany-based Dunker Umwelttechnik GmbH is
dedicated to environmental products and services for the shipping
industry with a specific focus on flexitank solutions, such as heating
systems, fitting, removal and disposal, emergency response, and
incident handling and analysis.
Trust and Dunker Umwelttechnik have developed an innovative
heater pad system with ISO tank-like heating time, which is four
times faster than standard rubber hose heater pads.
The two companies have managed to adapt a steam-based
heating system to a standard 20ft container with flexitank. It
consists of a series of galvanised steel pipes, covered by a steam
diffuser blanket providing around 15 sqm of heat exchange surface
area on the underside alone, and once steam starts to circulate
around the system a ‘sauna’ effect is created within the container
therefore maximising the heat transfer over a much larger surface
area of the flexitank and not just on the underside as with
traditional heater pads therefore eradicating ‘hot spots’.
Furthermore, seeing as rubber tubes are not used, a higher steam
pressure can be supplied if available (1.5 bar with 60-80kg steam
per hour) without fear of damaging the unit.
Being a reusable system, the designers say it will lead to greater
savings for regular users that decide to purchase outright, and it also
means the system can be rented for the less frequent user with the
possibility of a fixed tariff for heating.
Whichever option is chosen the faster heating means far less time
at the receiver’s factory or heating station and less time on a truck
chassis leading to further savings.
The equipment is easy and safe to operate using 0.5ins BSP fittings
for steam.
Training and technical assistance can be offered to customers who
either buy the equipment outright for multiple uses or wish to rent
the system on a spot or regular basis.
Trust and Dunker say the system will be of particular interest to
importers of: animal and vegetable fats (eg, palm oils/oleins, UCO,
fish oils, cocoa butter, tallow and pig fat), sweeteners, glycerine and
organic compounds.
