Dango & Dienenthal Inc. of Siegen Germany with established USA operations in Alliance Ohio is noted for its forging tool equipment supplied to the steel industry. Automated fluid filtration equipment is a component part of the massive forging equipment cooling and lubrication systems. The DDS, short form for Dango & Dienenthal Systems, filtration/strainer equipment sold worldwide as a separate product line is now to be produced and marketed in the USA. DDS automatic filter/ strainer design, performance capability, and quality for each model is unequalled by any other similar systems. Important to know is that the DDS JET system flow velocity creates vortex harmonics through the wedge wire filter kills zebra mussel larvae.

Pipe Tech has 25 years experience in the strainer/automated filtration systems. We provide engineers and user customers with optimum performance recommendations, provide site startup and follow on service.

DDS will enter the us markets with its patented inline (JET) Jet Filter, 4 to 110,000 gpm, 50 to 5000 micron separation, 22 to 900 psi service for flanged line sizes 2 through 120 inch. Pipe inline installation in any mounting positon offers a space and flow volume advantage over all other types of automated strainers, duplex and conventional basket strainers. Typical solids blow down is set for 20 second on the hour with differential pressure blowdown backup.

Additionally, DDS will offer the (DDF) Filterautomat conical rotary drum filter capable of heavy solids removal ( steel, paper mill and hydrocarbons industries) 20 to 17500 gpm, down to 5 micron separation, 12 to 900 psi for flanged line sizes 2 though 40 inch. Rotating drum concentrated pressure screen cleaning on set time and differential pressure.

Materials of construction: CI, SS, CS and Special Alloys.
