| Flo-Matix Company designs and builds pneumatic leak test systems to customers' needs. Customers specify limiting dimensions, pressure needed, and any special requirements, like automated engagement, overpressure needs, filtration, etc. Flo-Matix uses these specification to determine the layout of the equipment and automated test sequence. They build the test system, test it, and deliver it within the time constraints specified. NOTE: Click on any of the thumbnail photos below for full size blowup. |

 Electropneumatic Leak Testing SystemThis control system is used to detect leaks in a heat exchanger by monitoring air flow through a closed loop. The system utilizes a SLC500 fixed PLC to drive the logic sequence, a digital flowmeter with redundant panel mounted display, and leaktight pneumatic components. Due to the critical nature of precision flow measurement, a pneumatic buffering system is used to stabilize the air flow through the system prior to testing. Flo-Matix designed an adjustable, slide-mount fixture to allow multiple sized heat exchangers to be tested. Custom FasTest pneumatic connectors are mounted on Bimba cylinders to seal the test piece to the system. |

 Electropneumatic Leak Testing SystemThis is a turnkey system designed to leak test heat exchangers. It includes the operator control panel and test fixture. Once a heat exchanger is placed in the fixture, pneumatic valves are sequentially opened and closed to seal and pressurize the test piece. Any pressure decay, monitored by a differential pressure switch and gauge, indicates a leak. FasTest pneumatic actuators are used to seal the test piece. A SMC ECC-50 valve controller runs the pneumatic sequence. |

 Electropneumatic Leak Testing SystemThis control system is used to leak test multiple sized airtight conduits by monitoring mass air flow through a closed loop. The system uses two adjustable slides on Tompson bearing rails to place the test piece. The piece is sealed using custom FasTest pneumatic connectors and Flo-Matix designed fixture brackets. An Allen Bradley Micrologix 1000 PLC controls the test sequence. A Sierra Instruments mass flow meter measures leakage rate and displays it via a Yokogawa digital process meter, which is programmed to indicate failure at a customer specified setpoint. |
