About JASC
Jansen’s Aircraft Systems Controls Inc. (JASC) engineers and manufactures actuators and fluid control components for power generation, aerospace, space, defense and research applications.
Our products are suitable for use in aviation, space, chemical, food and beverage, marine, petroleum production and refining, water, oil and gas, mining and gas turbine industries. Providing solutions for a wide range of valve and control applications for its customers, JASC has experience with hydrocarbon liquid and gaseous fuels, sour gas, synthetic and hydraulic oils, pneumatics, gaseous hydrogen and silane, nitrous oxide, ethylene, cryogenic fluids and water.
Whether you need a complete system design or replacement of an integral component within your current system, JASC can design and manufacture it as well as improve the operational capability and performance. Our extensive analytical capabilities will benefit any project by adding useful insight into the behavior of the part, assembly or system operating under the anticipated conditions it will experience in the end-use application prior to fabricating hardware. This approach reduces risk, cost and time to product realization.

JASC Installations, LLC: A new era in customer service for reliability upgrades
JASC is pleased to announce the creation of JASC Installations, LLC, a company which specializes in the installation of gas turbine control hardware which significantly enhances both start-up/transfer reliability and operational availability. After having spent many years evaluating both system and component deficiencies which can make system maintenance programs expensive and ineffective, JASC patented a wide range of products specifically for use in liquid fuel, purge air, water injection and flame detector systems.
This considerable expertise, which was applied to component design, is now utilized to troubleshoot and resolve system related issues as well. A variety of conditions can be present at any given turbine site. Consequently, installation of our products is not a guarantee that the desired level of operational capability will be achieved unless all underlying issues are also addressed as part of the process. JASC Installations ability to diagnose and correct the root cause(s) of issues which negatively impact system performance after fuel system components upgrades have been performed makes it a very unique service. Accordingly, JASC Installations is now providing turnkey fuel system upgrades, project management and technical support for customer liquid fuel system projects of any size or scope. Installation services improve the operational capability of even the most problematic liquid fuel system.
There are a wide range of gas turbine fuel systems being utilized throughout the world, many of which are dual fuel, meaning that they alternate between natural gas and diesel fuel for turbine operation. While significant advances have been made in the electronic control of these fuel media, the hardware remained virtually unchanged for the back-up liquid fuel system for decades. JASC developed a variety of products:
•Check valves which use water to cool their internal components preventing diesel fuel from solidifying while the turbine is operating on natural gas.
•Purge air check valves which are capable of sealing to an ANSI class 6 standards (bubble tight) while requiring only 1/2 psi of pressure to open.
•Water injection check valves that provide an ANSI class 6 seal and are not prone to excessive wear due to high frequency oscillation or chatter.
•Three-way purge valves capable of alternating between purge air and liquid fuel; a water-cooled version of the design prevents solidification of diesel fuel in it as well. JASC Installations provides services which fully integrate these products into an existing system to minimize cost while addressing the fundamental issues impacting reliability.
In this day and time, it is rare that the most effective solution to a problem is also the least expensive. Relative to fuel systems, JASC has accomplished this feat for installation of back-up liquid fuel system upgrades, operational reliability and total cost of ownership. Transfer success can be improved from the industry norm of 30% to rates approaching 100%. The formula for success is as straight forward as it is simple. Specifically, provide bolt-in hardware that closely matches the turbine owners currently installed configuration to minimize piping changes; design hardware which is capable of making the system in which it is installed operate at levels that approach 100% reliability and availability. Couple these characteristics with savings ranging from $100,000 to $1,000,000 per turbine on installation costs alone and you have an option which warrants consideration in any fuel system upgrade discussion.
For an “F” class gas turbine which utilizes liquid fuel check valves, an upgrade would be about 1/3 the cost of other options. Components supplied for the upgrade would include water-cooled liquid fuel check valves, water injection flow proportioning valves and a Smart Fluid Monitor. The type of purge air valve used would determine whether a JASC designed valve would be required. Savings on installation would be at least $100,000 per turbine. Savings on other models of turbines would be greater.
For an “F” class gas turbine which utilizes three-way purge valves, a fuel system upgrade would be about 1/5 the cost of other options. Required equipment would include water-cooled three-way purge valves, water injection flow proportioning valves and a Smart Fluid Monitor. A gas turbines owner’s savings for an installation would be approximately $1,000,000 per turbine. The significant difference in cost is tied directly to the technology, which is available for this particular configuration.
Finally, after examination of installation cost, material requirements, specifics of component design and total cost of ownership, gas turbine owners will have a great basis for comparison. JASC Installations reliability upgrades for back-up liquid fuel systems, like their products, set a new standard for the industry. For more information contact sales@jasc-controls.com
