Schünemann SAB delivers largest filters in entire company history
At a height of 6.5 m, a foot print of 3.5 by 3.0 m and a weight of roughly 6.0 to of empty weight our three filters are able to deliver more than 17,000 m³/h of seawater at 10 bar for a continuous cooling application of a refinery. By using the Bernoulli principle the patent declared filters have been designed and manufactured in close cooperation with the end-user and the EPC contractor.
By having 75 years of experience and a very healthy financially back ground it is a waltz for SAB executes projects like this size.
We are very proud of our performance and would like to thank to all our colleagues and sub-suppliers for the great support and teamwork!
Here is the bird's eye view of the filters.

25 Years of the SMM - 75 Years of SAB
The Marine Exhibition at the SSM in Hamburg and the Marine Valve and Filter Manufacturer SAB in Bremen had anniversaries in 2012, both celebrated notable Birthdays with the 25th Birthday for the SSM Marine Exhibition and the 75th Birthday for SAB.
SAB again proved itself for its innovative design and as part of their stand exhibits presented their latest Marine Turbine Engine Start Reducing Station. The station has been design to operate without droop enabling more onboard starts, weighing in at 400kgs the 2 stage system allows for a reduction from 330bar to 3.5bar with an air flow of 6000 Nm3/hr. The fact that the station has been proven, orders have been received and the first units are now in active service on board military ships led to many interesting conversations with our current and new working partners who have all shown interest in fitting the stations in their new build.
SAB will again be exhibiting at the 26th SSM Marine Exhibition in 2014 and looks forward to welcoming you all to our stand.

June 2008-February 2009 - Econosto Nederland B.V. and SAB supply self-cleaning Automatic Filters Type F450 for residential area Duindorp near Den Haag with approx. 800 apartments
3 pieces F450 DN150 and 1 piece F450 DN100 have been started up successfully for protecting heat exchangers. The heat exchanger units are being operated with harbour water in Scheveningen / NL. Heat energy is taken from the seawater and further used by heat pumps. By using sea water approximately 800 apartments are heated in winter and cooled during summer time.
The heating and cooling process depends on the ambient temperatures, so the heat exchangers are operating with flow rates of 60 – 1.030 m³/h. Several pumps and valves are integrated into an intelligent control system, supervised by a master control unit.
Hereby Econosto and SAB take part for environmentally friendly energy systems in HVAC.
October 2008 - Mashimpeks and SAB supplied Automatic Filters with Electrical Drives for Russian Power Plant
7 pieces Automatic Filters type F450 for continous filtration have been supplied in March 2008 to the power plant „Konakovskaja“ near Moscow. Standard pneumatic driven actuators could not be used, due to the special operating conditions on site. According to special customer requirements the filters have been equipped with electrical actuators.
The design of the filters was made for flow rates from 500 m³/h up to 1.500 m³/h each. The filter bodies are made of galvanized carbon steel and medium contacted internal parts are made of stainless steel 1.4435 / 1.4571 / 1.4412. The filters are in use for the filtration of water from river Wolga. Solid particles and organisms are separated and flushed out automatically with highest safety and efficiency. Separated parts cannot enter the heat exchangers, whose efficiency is increased.
October 2008 - Mashimpeks and SAB supplied Jumbo Filter for Russian Fertilizer Plant
High flow rates up to 4.000 m³/h are no problem for our filter type F450. The filter DN600 made of GRP with internal parts made of stainless steel was supplied to the Russian fertilizer company „Beloretschenskije“ . The pneumatic actuators assure best reliability at lowest costs.
The economic treatment of cooling water is getting more and more into the focus of interest of various industries worldwide. Our filter systems are high valuable contributes for protection of natural resources and cost saving.

November 2007 - Econosto Nederland B.V und SAB realise project "Kraanspoor" Automatic self cleaning filter F450 in building services engineering
In the port of Amsterdam a former shipyards area is to be integrated into a modern urban development project. The "Kraanspoor" building is part of a concept that includes ancient industrial memorials into modern architecture. The waste land in the harbour area was re cultivated.
Our filter F450-DN80 made of stainless steel 1.4571 with fineness 200 µm is installed for harbour water intake. This is for use in plate heat exchangers of the cooling system / air conditioning system. The filter is designed for flow rates from 38 - 80 m³/h.
October 2007 - SAB meets BASANT
Two automatic self cleaning filters type F450-DN600 have been successfully started up in April 2007 at BASF in Antwerpen / Belgium. The filters are in use for filtration of 4.700 m³/h brackish water in order to protect plate heat exchangers in the cooling water supply station.
The filter bodies and covers are made of glass fibre reinforced plastics (GRP), other medium contacted parts are manufactured from stainless steel 1.4539 with a strainer made of a perforated titanium plate. The combination of materials is very well proven many times in critical applications. This is important because the brackish water is taken directly out of the harbour.
September 2007 - milestone for SAB
The 50th type F450 jumbo format filter left the production hall in Bremen at the beginning of September for shipping to Saudi Arabia.
The filters are intended for the cooling water filtration in the world’s largest refinery under construction. Designed and built in accordance with the strict ASME guidelines and fitted with high quality Hastelloy® and titanium built-in parts, the 6 metre high GRP filters with an operating weight of 5.7 tons satisfy the highest quality requirements. Each filter is equipped with its own controller for the operation monitoring. The processing sequences are synchronised and thus optimally integrated in the overall control technology using a separate SAB master controller.
