According to DVGW regulations, treatment chairs in the field of dental technology need to be physically de-coupled from the public drinking water supply. Typically, piston pumps are used as internal pressure sources to produce the required operating pressure for both instruments and the spittoon. A low-noise control unit with solenoid valves from KUHNKE serves to pneumatically drive these piston pumps.

To increase patient comfort, treatment chairs in the field of dental technology come with a variety of solutions. For example, lumbar supports and massage functions are offered to increase the overall well-being of the patient. For such applications, KUHNKE offers low-noise electronic components with pressure regulators and solenoid valves for the precise control of the air chambers integrated into the back rest of the treatment chair.

This solution required high resistance against chemicals. The program-controlled cleaning unit can hold up to four dental instruments for cleaning and lubricating. The KUHNKE 6-way valve unit provides the valves to control the supply and disposal of water and disinfectants during the cleaning process.

This scaffold shaping device allows the production of metal-free crown and bridging scaffolds based upon a totally new technology. The resulting scaffolds are made of a fiber-enforced Vectris material by means of a vacuum/pressure forming process before they are hardened with infrared light. KUHNKE developed and manufactured a compact valve unit to control the vacuum and pressure processes inside the device.
