Pressure Vessels

Air exchange in sealed housings? No Problem! Our pressure equalisation elements (formerly Gothe & Co. GmbH) have proven themselves reliably worldwide. High temperatures and adverse environmental influences provide continuous pressure fluctuations in sealed housings – protect your sensitive electronics and improve the lifetime of electronic devices with our pressure equalisation elements. Reliable reduction of condensate formation Protection of harmful fluids and particles Special Features Flat construction Easy installation (from inside or outside) 100% Salt retention capacity Very robust Diverse versions Air passage of up to 400 ml/min Technical Data Mounting body/cap brass (optional nickel-plated, chrome-plated or stainless steel) Membrane ePTFE (oleophobic) O-Ring NBR (optional EPDM, FKM or silicone) Water ingress pressure > 0,6 bar Protection class DIN EN 60529 IP66, IP68 (installed) Acceptable temperatures - 40 °C … + 80 °C (150°C temporary)

Our mechanical pressure switches are entirely “Made in Germany”. Hydrostar’s extensive and long product experience along with continuous improvements in hydraulic pressure measurements enables the production of high-quality, accurate and reliable mechanical pressure switches. These properties have proven themselves consistently worldwide. The core of the pressure switch line is the special extreme long-lasting sealing combined with the piston-springprinciple and its exceptionally accurate and reliable change-over switch. The minimum switching path with an additional throttle bore allows for a lengthy and durable life cycle. Another special feature is the potential adjustability of the pressure switch on client-side, even after the installation. Mechanical piston pressure switch for pressure monitoring Pressure range 5 to 350 bar Special Features Precise and Reliable Compact Design Change-over switch High overpressure security

Testing by means of mass flow method - Multi-channel applications possible - Different measuring ranges possible - Electronic pressure regulator - Completely remote controllable - Optionally remote controllable via ProfiNet

The flow tester CETATEST 915 is used for flow testing with compressed air. It includes a measuring system consisting of laminar flow element (LFE) and differential pressure sensor In the direct test method the air, provided by the internal pressure regulator, flows through the measuring section before it enters the test part.In the indirect method, the measuring section is located in the outlet flow of the test part. Due to the special design of the measuring section a laminar ow is generated. The resulting pressure difference is directly proportional to the volume flow. With the optional electronic pressure regulator and four calibrations for up to four test pressures the application range is substantially expanded. Special versions: The CETATEST 915-G is a fully automatic flowmeter for the detection of leaking parts. Typical applications: 915: Testing of valves, vehicle exhaust systems, pipes, membranes, 915 G: Gas appliance industry, after-work jobs in the automotive industry
