Omniflex: a 50-year history

July 2015 News

The beginning

On the 1st July 1965 a young chemical engineer and entrepreneur started an innovative industrial electronics company in Durban, South Africa. His idea was to take advantage of the newly invented transistor to make electronic modules for industrial automation, designed to replace unreliable mechanical relays.

That young engineer was John Moshal, and the company was Control Logic. Through some changes of ownership, and changes of name through the last 50 years, that company and that innovative spirit still thrive today in Omniflex.

Joined soon afterwards by Alan Murray, an innovative designer, the pair pursued their passion for developing products for the process control market. From their Durban base they launched into the sugar industry in KZN.

Conlog (short for Control Logic) quickly earned a reputation in the industrial controls market for doing its best work where direct customer interface was required. The ability to take on challenges other companies shy away from has always been and remains one of the company’s strengths.

By 1970 Conlog was commissioning large turnkey installations throughout South Africa.

The company created a vertically integrated in-house capability covering every aspect of design and production from metal fabrication to software development. The company became a pool of innovation through early technology adoption and a can-do attitude.

In order to continue to grow, Control Logic expanded its capital base in 1971, when Anglo American acquired 50% of the company.

In 1978 the Durban based company again leapt ahead with the invention of revolutionary alarm and interface technology for the Sasol 2 and 3 plants that helped establish the company as the largest local manufacturer of industrial electronics in Africa.

Using its depth of industrial experience and innovative spirit in electronics design for the harshest environments, the company diversified first into automotive electronics, by pioneering speed controls and car alarms, and later by inventing the technology necessary to launch the prepayment electricity metering sector in South Africa.

In the late 1980s, Conlog split into three divisions to focus on larger international market opportunities:

1. The original industrial division, which became Omniflex in 1996, continued to provide the technical innovations for the company’s developments.

2. The automotive division became a leader in vehicle security systems with international exposure through a customer base that included Volkswagen, Toyota, Mercedes Benz and Samcor.

3. The pre-payment metering division became a world leader with its patented billing system to manage payment and recharge of meters.

In 1997, after the end of apartheid, when Anglo American divested from its industrial companies to focus on mining, the industrial division, the original core of the company, was acquired by engineering director David Celine with financial support from Paul Gaines, a private investor. As CEO of Omniflex today, he continues to build on the spirit of innovation that was started back in 1965.

Omniflex expertise

Remote monitoring specialists

With 50 years of experience in designing for harsh industrial environments, Omniflex today focuses on the expanding market of remote monitoring for a range of applications.

Combining experience with innovation is what Omniflex is all about. Be it radio, GSM, Ethernet plant networking, or last mile cable saving connections, all are skill sets that have been honed over the last 50 years. CONET, Omniflex’s industrial local area network was developed in the early 1980s, well before the word fieldbus was even invented. The Conet network remains unmatched for distance and performance on low grade cables in harsh environments.

Omniflex’s innovation also brought Internet based monitoring to the industrial space, leveraging the pervasive power and availability of GSM networks and the Internet with Data2Desktop solutions. Omniflex leads in a range of remote monitoring services for water quality and management in southern Africa.

Critical alarm and event recording

Rejecting the premise that process alarm annunciators were obsolete and being overtaken by computers, Omniflex introduced the world’s first microprocessor based alarm annunciator with solid state LED lights. Omniflex is now a global leader in this technology with the first software based alarm annunciator to be assessed and approved under the EMPHASIS scheme for use in nuclear applications.

Radiological surveillance systems

Built upon the company’s in-house technologies and customer service, Omniflex has established itself in the UK as the leading independent supplier of radiological surveillance systems, supplying all the major UK nuclear authorities and now expanding into nuclear medical markets such as PET centres.

Cathodic protection

Working closely with leading consultants, Omniflex’s Australian office has pioneered new techniques in the field of impressed current and hybrid cathodic protection systems, to improve energy efficiency and remote management to reduce life cycle costs and reduce the environmental impact. These are now considered world leading products in this market.

Exporting to the world

Omniflex has been actively exporting products and competing with the best in class since the 1970s. Currently the company is set up with the factory and sales operation for Africa, Middle East, Asia and the Americas located in South Africa; the European sales office located in the UK; and the Asia Pacific including Hong Kong, China and Taiwan serviced from Sydney. Over 50% of the company’s annual turnover is from export.
