Sierra is an expert in the control of high flows of gases. With our large and powerful control valves and PID valve control, Sierra`s mass flow controllers, with industry-best low pressure drop, can control much higher flows than equivalent flow controllers with minimal pressure drop requirements.
Our flow instrumentation has been on numerous space shuttles and is currently on the International Space Station. Our high pressure mass flow controllers are used extensively in the development of advanced composites for aerospace.
Low flow measurement and control is a difficult application. Ultra low flow mass flow controllers can accurately control flows from 0.1 to 0.4 sccm which is ideal for measuring and controlling doping gases for pilot plants and other research houses.
Thermal mass flowmeters and controllers are ideal for Argon application where precision is key. Sierra specializes in accurate mass flow measurement and/or control of Argon gas. Popular applications range from general industrial process control, inerting and steel purification processes to name a few.
Precision high pressure mass flow control is very difficult. Sierra has met this challenge with a patented high pressure mass flow controller design that offers impermeable elastomers with very little leakby.
Our mass flow controllers in particular see extensive use in bioreactors, pill coating and the creation of artificial atmospheres for research. Our flow meters are used to leak test critical medical devices like stents, while our larger industrial devices are used to heat or steam-clean bioreactors and in facilities management in hospitals.
Thermal mass flowmeters are ideal for Carbon Dioxide metering and mass flow control. Sierra specializes in accurate mass flow measurement and/or control of CO2 gas. Applications range from general industrial process control across numerous industries to Green House Gas monitoring requirements and general research.
A variety of thermal analysis techniques, such as Thermo Gravimetric Analysis (TGA), Differential Thermal Analysis (DTA) and Differential Scanning Calorimetry (DSC) rely on high-performance mass flow control.
Thin film deposition processes, e.g. reactive PVD (Physical Vapor Deposition), require a repeatable gas flow of the reactive gas to ensure reproducible film properties. With its industry-leading repeatability of < ± 0.15% FS and very small long term drift the Axetris MFC 2100 series supports you in making your equipment stable and easy to use for your customer.
Environics gas mixing, blending and dilution systems provide for precise mixing of gases for a wide variety of clinical applications. Our systems can produce gas concentrations from percent to ppb levels for single or multi-point calibration. The high accuracy of our mixers make them the units of choice for a wide variety of laboratory and research applications. For example, Environics Biological Atmosphere Incubation Mixers provide stable and accurate gas mixes for any laboratory or clinical need. You can...
More and more food packaging companies are utilizing Modified Atmosphere Packaging (MAP) or Equilibrium Modified Atmosphere Packaging (EMAP) to preserve the shelf life and/or appearance of their packed food. At Environics, we know it is essential that your MAP/EMAP gases be consistent and accurate in order to guarantee the desired quality in the end products.
