    Mass Flow Control Enables Chocolate Aeration

    Alicat products being used in the chocolate industry? Aerated chocolate is increasingly popular because of its particular mouthfeel; bubbles with chocolate. So how are bubbles typically added to chocolate? The process involves high performance mass flow control. Bubbles are formed when high pressure gas is injected into liquid chocolate for aeration. The gas used is […]

    High Flow Control for Gasification

    Alicat mass flow instrumentation can streamline and provide additional efficiency and safety in gasification and syngas product processes. Gasification is a process in which biomass or fossil fuel is converted into carbon monoxide, hydrogen and carbon dioxide (syngas or synthetic gas).1 According to Carnot’s theorem of thermodynamic efficiency, the syngas produced is more energy rich […]

    Aerobic vs Anaerobic Wastewater Treatment: An Overview

    Bioreactors are now a common part of wastewater treatment. Alicat’s revolutionary differential-pressure based mass flow controllers allow for extreme flexibility in mass flow control and the response times needed to make this process efficient and cost effective.

  • Tough environments call for tougher instruments

    Many processes require corrosive gases like ammonia or sulfur dioxide that cause damage to the instrument. These Alicats are built to withstand tough process conditions; configured to thrive in harsh ambient conditions.

  • Achieving more repeatable coatings with faster, more precise pressure control

    Achieving more repeatable coatings with faster, more precise pressure control Issue: Uneven coating quality and poor repeatability, resulting from fluctuations in vacuum chamber pressure.  Cause and Context In the rarefied atmospheres of vacuum coating systems, pressure fluctuations arise—and small changes count for a lot. From the interaction of control components and asynchronous operation of those […]

  • TIG (Tungsten Inert Gas) Welding

    App Note:TIG (Tungsten Inert Gas) Welding In the TIG (tungsten inert gas) welding process, a tungsten electrode is used to provide an electric arc forwelding. A sheath of inert gas surrounds the electrode, the arc and the area to be welded. This gas shielding process prevents any oxidization of the weld and allows for the […]

  • Reliable Air Delivery for Automated Liquid Paint Application

    Maintaining accurate response control over the air flow is essential to paint job quality thereby reducing costs on every part painted.

    Automation of Paint Application Pressure Control System

    App Note: Automation of Paint Application Pressure Control System ACME Robotics has a semi-automatic paint spraying machine. Semi-automatic, you ask? What does that mean? It means that if they want to adjust the flow of N2 around the paint distribution capillary tube, the must do it manually via a regulator. They want to produce this […]

  • External Ion Gauge Vacuum Control System

    App Note: External Ion Gauge Vacuum Control System Research projects involving isolated chambers with decomposing organic components often use rotometers. The external ion gauge vacuum control system uses a special configuration of the Alicat single valve pressure controller. Alicat’s External Ion Gauge Vacuum Controller was designed specifically for the vacuum coating industry. This innovation circumvents […]

  • Product Sparging

    App Note: Product Sparging Sparging is a process where a gas is injected into a liquid to achieve a variety of results. The sparging bar has many fine holes through which the gas is transferred into the product in the sparging tank. Maintaining a constant flow rate is crucial in order to obtain the desired […]
