Capabilities
Advanced Fluid Conditioning Solutions Using the Fluid Care Center
®
As both customer requirements and government regulations continue to drive more efficient filtration, developing
new products requires a state-of-the-art testing laboratory. Schroeder has leveraged 65 years of filtration
knowledge and brought well known standard tests and custom engineered testing capabilities in a single location to
form what we are now proud to call the Fluid Care Center or FCC.
The custom engineered equipment and tests are developed to reconstruct our customers’ operating environments while
measuring the implications of choosing different fluid conditioning solutions. This newly available data allows designers
to optimize tank design as well as reduce cavitation, size, and the cost of their hydraulic systems. The FCC will
allow Schroeder to deliver innovative, high quality solutions to our customers and help them to deliver better
machines at lower cost by testing performance rigorously, quickly and efficiently.
Standard Housing Testing
Schroeder tests the performance of its housings to the
recognized, but more stringent, NFPA standards for
pressure performance, giving our customers peace of mind.
Static burst pressure and cyclic rated fatigue pressure
(RFP) testing per NFPA/T2.6.1 conservatively determines
rated pressures for filter housings.
Schroeder publishes pressure drop vs. flow testing as
specified in ISO 3968. Lower pressure drop reduces power
requirements, which means energy savings and reduced
fuel costs. Schroeder also uses the same equipment to
verify cracking and full flow pressure settings of filter
bypass valves and indicators.
Flow Bench Cyclic Testing
Standard Element Testing
Schroeder tests to industry standards for element performance so
our customers can compare our element to our competition. The most
common and important test for filters is the multi-pass testing (MPT) per
ISO 16889. This test provides critical performance data for filter elements:
filter efficiency(ß), beta stability, and dirt holding capacity(DHC). In
addition to testing the performance of elements, Schroeder also tests
filter integrity. Filter element collapse/burst testing per ISO 2941 tests
the strength of the element construction itself, including the media,
support layers, tube, and end caps and provides assurance that an
element will hold up in high differential pressure. Schroeder uses a
pull tester to check the bond strength of the epoxy/end cap adhesion.
Additionally, SI has a bubble point tester which provides a non-destructive
Multi-Pass Test Stand filter element integrity test.
Fuel Coalescing Filter & Element Testing
For fuel coalescing filters and elements Schroeder tests according to three industry standards in order to develop filter
and element technology and for benchmarking against competitor products. The three standards are as follows:
■ SAE J1488 is a fuel/water separation test with continuous water injection of .25% of the fuel flow rate. The test
is performed with the water injected upstream (suction side) of the pump resulting in emulsified or finely dispersed
water droplets.
■ SAE J11839 is a fuel/water separation test with continuous water injection of .25% of the fuel flow rate. The test
is performed with the water injected downstream (pressure side) of the pump resulting in larger water droplets.
■ ISO 16332 is a fuel/water separation test with continuous water injection of .15% of the fuel flow rate. The test is
performed with the water injected either downstream (pressure side) or upstream (suction side) of the pump
resulting in emulsified/finely dispersed or larger water droplets, respectively.
