INTERTEC is a supplier of unique systems designed to provide reliable protection of sensitive field-mounted instruments. The company was founded in 1965 by Dr.-Ing. Joachim Hess, who recognized the problem of inadequate protection of electronic instruments in the field of engineering. Neglect or failures in instrument protection, however, can seriously affect plant safety and the operation of the complete system. Even operating and maintenance costs can be reduced considerably by providing adequate instrument protection.

Today, more than half a million INTERTEC protection systems ensure safe operation of instruments, analyzers, mobile phone and radar quip- ment, signalling plants, transmitters and many other installations world-wide. Due to extensive expertise in engineering, constant innovation and product improvement INTERTEC has become the world's leading manu- facturer in this field. Twenty patents obtained for our products and unique solutions attest to INTERTEC's know-how, and several new patents are issued every year.
