Meanwhile, we manufacture refrigeration accessories such as pressure and temperature controls, flow switches, thermostats and solenoid valves.

Keram has spent a huge amount of investment in manufacturing, testing equipment and laboratory. Each manufacturing procedure is under the inspection of different testing machines to ensure that every unit is properly assembled and reach the design quality. Using the most reliable components in our unit is also another quality control method.
