R&D Highlight: Water Sensor

  • September 2, 2015

ChemTec is an engineering-driven company, and engineering is really about applying the Laws of Physics. We’re familiar with analyzing gas flow rates, accounting for expansion coefficients, and monitoring the position of suspended magnetic pistons, but optical engineering is outside of our realm. Or it was until a customer set us a challenge we couldn’t resist.

CCM Series & Gas Analyzers

  • December 5, 2014

Gas analyzers are used in many industrial processes and play an important role: they are used to verify the presence or lack of presence of a particular gas or multiple gases. For example, in metal fabrication oxygen is used during the process of smelting iron ore into steel. Oxygen (O2) removes impurities from the steel. As the third most abundant element in the universe, Oxygen is the most widely used gas consumed by all living beings and is used for industrial purposes and applications including chemical, medical, aerospace, water treatment, semiconductor, food/beverage, and pharmaceutical. On the other side of industrial processes, analyzers detect the presence of gases such as sulfur, carbon, argon, nitrogen, and hydrogen. These gases can be dangerous if present in the atmosphere during manufacturing. Detection of these gases can be crucial to the safety of the plant and personnel.

Product Spotlight: Excess Flow Valves

  • April 1, 2013

ChemTec’s excess flow valves are perfect for a variety of industries. Below are some examples.

Industry Example 1: Semiconductor Fabrication

Example of a semiconductor

Example of a semiconductor

Applications include:

  • Installed in-line on hydrogen gas feeder lines; responsible for supplying hydrogen gas into the plant, delivering hydrogen to multiple areas within the plant.

Product Details: Ultra-high purity, electro-polished to 10 RA finish, manual reset excess flow valve with welded ¾” VCR fittings*, electric switch conduit, CE and ATEX mark. *The welded VCR fitting option is of great benefit to the customer providing easy removal and replacement for cleaning without damaging the unit.

 

Industry Example 2: Alternative Fuel

Chemtec's HP-EFV-750-S Excess Flow Valve in a CNG Filling Station

HP-EFV-750-S in a CNG filling station; installed on the line between the supply line and vehicle.

Applications include:

  • Natural Gas Vehicles
  • CNG Fueling Stations
  • Hydrogen Fuel Cells

 

Industry Example 3: Hydrogen Generators

ChemTec’s EFV-250-B Custom Unit for a Hydrogen Generator

ChemTec’s EFV-250-B (also available in 316 SS) custom unit for hydrogen generator OEM; installed at the base of cell phone towers

 

Applications include:

  • CNG (compressed natural gas) filling stations
  • Housed within NGV’s (natural gas vehicles)
  • Hydrogen generators in cell phone towers

 

Industry Option 4: Food & Beverage

Applications include:

  • Packaging Equipment – bursts of nitrogen are used during the sealing stage in both dry and liquid packaging processes. Used in Cap feeding; Sealing; Bottling/Kegging/Canning
  • Cryogenics – used for dry goods packaging; dispensing of nitrogen for product freshness and bag sealing.
  • Specialty Gas distribution lines – used to monitor the dispensing of gases (CO2 or nitrogen) for beverage grade beer & soda consumption
  • Liquid Nitrogen dosing systems – for peanut packaging and wine bottling
  • Liquid Filling Systems – signal flow/no flow condition of liquids and monitor the amount dispensed prevents over/under fill.
  • Process Technology – CIP (clean in place) & SIP (sterilization in place) systems; UV Systems for disinfection; Recirculating chillers
  • Filtration – signal flow/no flow condition and monitor liquids; monitor prevents pump burn-out; can signal notice of filter maintenance. Used in Batch processing; Brewing process; CO2 reclamation; Filling; Pasteurizing; Reverse osmosis (removing chlorine and fluorine from water before brewing process)
  • Beverage Pumps – signal flow/no flow condition; monitor liquids; prevention of pump burn-out.

 

Industry Option 5: Marine

Applications include:

  • Reverse Osmosis Desalination – Installed to protect pumps, monitor flow, signals flow/no-flow conditions for quality; monitors operating pressures and fresh water flush upon shutdown. Units are available in materials suitable for use on seawater such as Monel 400, to resist corrosion, and 316SS which is suitable for all potable water applications.

 

Industry Example 6: Gas Utilities

  • Application: Natural Gas lines
  • Line size: 1” diameter or less is a common line size for most residential and commercial lines (i.e. homes, apartments, townhomes, condos, restaurants, plants & factories).
  • Placement: Installed in-line, between the main “T” and the home; where the line pressure is not less than 10psig.
