Welker possesses over 90 patents and continues to design, develop and manufacture solutions to the natural gas industry.



The high quality natural gas filters manufactured by Welker are designed to filter and dry natural gas to prepare it for use as an instrument supply. As natural gas flows through the filtration, water, aerosols, odorant, and liquid hydrocarbons are removed by the filter media, thus cleaning and drying the gas for use by downstream instrumentation.

Natural gas is organically a colorless and odorless gas which makes it virtually impossible to detect leaks. The solution is a Welker Odorizer that saturates the natural gas with a known amount of vaporized odorant. This environmentally clean odorization solution also features remote access to the system using a computer connected by Ethernet, modbus, or modem.
