Kenco Engineering

Kenco Engineering beginning in 1958, KENCO Engineering Co., an ISO 9001:2015 Certified Manufacturing Company has been recognized as a key supplier of instrumentation for various industries, including oil and gas, petrochemical, power, pulp and paper, water and waste treatment.

General Description of Kenco Engineering

KENCO enjoys worldwide recognition and leadership with its line of Liquid Level Gauges, which are used as visual measurement devices in various tank gauging applications. KENCO’s Oil Level Controllers are the standard device worldwide for monitoring and controlling the amount of lube oil consumed in stationary engines and compressors. An outgrowth of our position of leadership in this market are the rest of our Gas Compression Components.

KENCO’s main facility is located in Tulsa, Oklahoma. KENCO also has a sales and warehousing facility in Baton Rouge, Louisiana, which serves its customer base in the state of Louisiana.

KENCO was founded by Kenneth N. Mills, one of the first registered professional engineers in the state of Texas. He graduated from Rice University in 1933 and in the next few years derived many of the mathematical formulas used universally in petroleum equipment sizing. His work in the design of heavy oil field equipment brought him to Tulsa where he was the Chief Engineer for an oil equipment manufacturer. During World War II, he served as the plant manager in a munitions plant. After the war, he continued to work in the oilfield equipment industry in a sales capacity. His frustration with trying to assure quality in the equipment he sold led him to “build it himself.” KENCO was born.

KENCO’s level of success since its inception is a testament to Mr. Mills’ dedication to quality. KENCO’s mission is to provide products that conform to our customer’s requirements and deliver them on time at a competitive price. KENCO’s name represents quality to our vendors, ourselves, and our valued customers. Quality improvement is the most important job of every KENCO employee.

Mr. Mills ran the company alongside his wife Dorothy until his death in 1976, when his son, Steve Mills, assumed the role of President of KENCO. Steve, under the guidance of his father, had begun to work at KENCO several years earlier when he was completing his college degree at the University of Tulsa. In 1976, under the new leadership of Steve Mills, the company, with just 6 employees including Dorothy, was about to undergo a significant upturn.

With the oil boom of the 70’s, Steve began introducing products that would make KENCO a key supplier to oil companies and OEM’s, who needed devices to monitor chemical injection packages in the oil field. In addition, the entire line of Liquid Level Gauges was introduced and gave KENCO a worldwide presence. KENCO thrived under Steve’s leadership and became an important Tulsa manufacturing company, with a reputation as a trusted and reliable manufacturer of engineered products.

The third generation of family leadership began in the mid-1990’s, when Steve’s daughter, Kristin Ragland, and her husband, David Ragland, were introduced into the company. Steve continued to serve as President of KENCO until 2000, when he officially turned over the reins to this aspiring leadership team. Ken Mills, Steve’s son, also began serving the company in 2002. Steve continued to maintain a presence at KENCO as Chairman of the Board until his passing in December, 2007.

In 2006, KENCO completed a major expansion, when it moved from its 36 year old, 37,000 square foot facility into a new facility with 111,000 square feet. The new facility ensures that the management team has adequate space and resources to accomplish its current and future goals.

Today, KENCO has 3 family members that represent the family of its founder, Kenneth Mills. David Ragland serves as President of the company, Ken Mills serves as International Sales/Marketing Manager, and Chris Nelson serves as Purchasing Manager.

The company has grown to employ over 100 people and continues to introduce new products. KENCO is celebrating its 60th anniversary and its priorities have not changed. KENCO’s standard of excellence and commitment to quality engineering and manufacturing practices assures our customers of dependable equipment. We intend to maintain a strong family legacy, one in which Kenneth, Steve, and Kristin would be proud.

Ultrasonic Liquid Level Switches

Ultrasonic Liquid Level Switches

Ultrasonic liquid level switches are used in a wide variety of applications to detect the location of level in a process or storage vessel. These switches can be used in virtually any liquid. A complete offering of materials and mounting configurations are available to meet your application needs.

Thermal Differential Level & Flow Switches

Thermal Differential Level & Flow Switches

KENCO’s Thermal Differential Switches are designed for a wide range of flow and level applications. These switches can be used to direct either the overall liquid level or a liquid-liquid interface. They can also be used to detect a specific flow rate or flow/no flow condition in liquids and gasses.

KEFS Electric Float Switch

The KENCO Model KEFS uses a float to determine the presence or absence of liquid in a vessel at the process connection. The float arm assembly consists of a float at one end and a magnet at the other. As the level in the vessel rises, the float rises and the magnet falls. The magnet actuates a second magnet on the other side of the pressure boundary. This second magnet causes the switch to change state.

The pressure boundary contains no seals; it is a solid stainless steel barrier that passes a magnetic field, but no liquids. It is impossible for the process liquid to enter the switch enclosure through this barrier. The electrical contacts consist of a microswitch that can be either a single-pole, Double-throw (SPDT) or Double-pole, Double-throw configuration (DPDT). The SPDT Switch is available with either a 5 Amp or 8 Amp current load. The DPDT Switch is only available with a 4 Amp current load.

KPFS Pneumatic Float Switch

The KENCO Model KPFS uses a float to determine the presence or absence of liquid in a vessel at the process connection. The float arm assembly consists of a float at one end and a magnet at the other. As the level in the vessel rises, the float rises and the magnet falls. The magnet actuates a second magnet on the other side of the pressure boundary. This second magnet is the reactive component in the snap acting switch that opens and closes the pneumatic valve. Because of the nature of the design, adjustment is rarely, if ever needed. In the event that adjustment is needed, an easy to use adjustment screw is provided.

KPFS Pneumatic Float Switch

The Model KPFS is used to actuate pneumatic dump valves, such as the Model KDV Series Dump Valve, to control liquids in scrubbers, separators and other vessels. The pressure boundary contains no seals; it is a solid stainless steel barrier that passes a magnetic field, but no liquids. It is impossible for the process liquid to enter the switch enclosure through this barrier. The Model KPFS Pneumatic Float Switch can be ordered to have the pneumatic valve open when it senses a liquid level rising (-LR option) or open when it senses the liquid level falling (-LF option). A manual valve actuator is provided to open the valve manually, if desired.
