Continental Controls – Press Release

Continental Controls Corporation is providing all
control components necessary to improve fuel
economy and reduce emissions as well as your
carbon footprint on gas engines across Canada.

San Diego, CA
April 1, 2021, Continental Controls Corporation (CCC) working with Vortex
Production Services in Alberta Canada has now had many successful after
market applications utilizing the wide range of Emissions reducing products. By
installing CCC AFR control systems with Ulta-Low Emissions Control, and
enabling Vortex Emissions Target Solutions (VETS), Vortex has helped oil and
gas customers to meet and exceed current Environment Canada / NOx
Emissions Limits as well as Alberta Energy Regulator’s Methane Reduction
Requirements. By shrinking customers Carbon Footprint, it may even allow oil
and gas companies to qualify for Carbon Credits now or in the future.
The Canadian federal government recently announced that the carbon tax will
increase from its current $30 per ton of greenhouse gas (GHG) emissions to
$170 per ton in 2030 – an increase of 467% over 10 years. This announcement,
if made into law, is expected to have a profound effect on many consumers,
businesses, and industries in Canada.

“We are very excited to be promoting these fuels saving and emission reducing
products with a company like Vortex that can really help bring home these
benefits to their customers” says David Fisher President of CCC. “Now that
Canada is raising GHG emissions taxes it really becomes financially beneficial
for all oil and gas companies in Canada to work with Vortex to lower emissions
and potentially even save money.”

Ken Osborne, Vice President of Operations says “VETS is our Vortex Emissions
Target Solution to offer cost effective solutions to present and future emissions
guidelines”. “Our partnerships with Altronic and CCC allow us to upgrade older controls to meet the rigors of new Emissions compliance now and well into the

About Vortex Services:
Vortex services is the Exclusive Distribution for Continental Controls Gas Engine products through
Altronic LLC. throughout all of Canada.
Vortex operates three divisions. Packaging, Structures and Services. The Vortex Services Division has
one of the largest fleets of mechanical service trucks in Western Canada, operated by the most
experienced team of heavy-duty mechanics, with coverage across Alberta reaching into Saskatchewan
and British Columbia.
The CCC product line is central to the VETS (Vortex Emissions Target Solution) system. This is of great
value to Vortex as they continue to take advantage of the increased focus on GHG Emissions by
customers and regulatory bodies.

The Control box on the left monitors the entire Fuel Control, mixing and ratio
of Air and Fuel to the engine. The Catalyst Monitor on the right monitors a
variety of sensors and controls around the NSCR catalyst. In addition to
monitoring temperatures, pressures, and Air/Fuel ratio, it records the data for
future review.

Vortex integrated CCC Ultra Low Emissions System mounted on a Cat 3408 Gas Engine.

Vortex also adds a CCC FM 50 flow meter to record before and after fuel
consumption. This measurement is accepted by the Canadian Government as a
valid indication of Fuel Savings over a given time-period. This can provide a
calculation of Carbon Reduction which can result in Carbon Credits!

A Waukesha 7042 GSI with the addition of the CCC/Vortex system has reduced exhaust emissions not just to current standards but well below the goal for 2026 of less than 1gm/bhphr of NOx. This engine is has seen substantial fuel savings while lowering exhaust emissions of NOx and CO to future standards.

Gas Turbine Products

By providing an internal mass flow calculation, the CCC valve is able to insure accurate fuel flow by compensating for changes in supply pressure, back pressure and temperature. 

Light off can be achieved at a pre-determined flow which is ideal for a specific turbine  (versus ramping start flow through a range as is the normal practice with position based fuel valves).

The flow through design allows the AGV10 to tolerate extremely high dirt loads in the gas.  And with pilot stage filtering, the CCC valve will tolerate a substantial amount of liquids in the gas.

  • Electricic Fuel Control Valve
  • Built in Flow Measurement 
  • Integrated Sensors 
  • Power Requirement: 24vdc 1 Amp
  • Inline Design: Robust and Dirt Tolerant 

By choosing the optional embedded Acceleration Control the CCC valve will work with any PLC (and also with older analog control systems such as the CCC Black Boxes).

The CCC valves greatly simplify on-skid wiring and gas plumbing and the 24vdc 1 amp requirement eliminates the need for a new high voltage power supply.

One RS-485 serial port provides data via the modbus interface such as: Gas Inlet Presure, Differential Pressure, Gas Temperature, Engine Manifold Pressure, Measured Fuel Flow and various other On Board information available for control and diagnostics.

ECV5 Emission Control Valve

Emission Controls

The ECV 5 is a complete Emissions Control System for Gas Engines. The ECV 5 can be configured for controlling either rich burn or lean burn gaseous fueled engines (fuel can be either natural gas or other alternative fuels).

The system consists primarily of the variable pressure control valve which accepts an input from either a narrow band or a wide band Oxygen sensor located in the exhaust of the engine. The ECV 5 valve will vary the fuel pressure based on an O2 setpoint compared to the actual O2 reading from the oxygen sensor. This closed loop, variable pressure control technique is patented by Continental Controls and it offers a superior method for minimizing emissions.

The ECV 5 is an electronically controlled servo valve with the electronics to control the Air/Fuel Ratio included inside the valve. It utilizes a nested loop control scheme with the outer loop controlling on position based on feedback from an LVDT. The inner loop controls on pressure based on feedback from an internal pressure transducer which measures downstream pressure. This two loop approach provides exceptionally fast response while still providing incredible accuracy.

  • Full Authority Fuel Valve
  • Fully Automatic Air/Fuel Control
  • Maintains Emissions Compliance even with Changes in Heating Value or Load
  • Rich Burn or Lean Burn Control
  • On Board Diagnostics and Optional Display

When used along with a three way catalytic converter, the ECV 5 can meet even the most stringent emissions requirements for NOx, CO, and NMHC. The ECV 5 is generally excepted to meet BACT (Best Available Control Technology) standards.

The ECV 5 can be used in a complete stand alone mode without a display. In this case a laptop computer is used for the initial set up of the operating parameters.

Many times local air boards require the monitoring of other items that might affect emissions. Other items to monitor might include, pre and post catalyst temperature, O2 sensor feedback, warm up time, and others. By adding the optional display (ECVI) all of these items and the general health of the ECV 5 and oxygen sensor health can be monitored.

The ECV 5 offers on board diganostics (OBD) to provide operator feedback for conditions that would indicate a potential problem in the emissions control system. The ECVI display can turn on an alarm either attached to the ECVI or via a discrete output to a station alarm to indicate a problem. Most often, this would be related to an Oxygen sensor requiring replacement.

The ECV 5 excels at applications that challenge most competing air fuel ratio controllers. When the heating value of the gas varies, or the application requires large load transients, or supply pressure varies, many systems can not handle these changes. The ECV 5 has the speed and the range, along with the patented variable pressure control, to keep the engine in compliance even when these difficult situations arise.

The ECV 5 can be used to control engines in a lean burn mode when used in conjunction with a wide band oxygen sensor. Lean burn control offers many advantages over Rich burn such as reduced exhaust temperatures, improved fuel economy, and possibly reduced maintenance and longer engine life.

Dual bank engines such as most Waukesha models are ideal canidates for the ECV 5. On these dual bank engines one ECV 5 is used for each bank when there are separate fuel manifolds. On some engines even though they are dual bank, there is a single manifold and pressure regulator. On these engines, a single ECV 5 can be used.
