Retractors are extendable cleaning nozzles. By using retractor nozzles, the highest level of safety and hygiene can be achieved. Our selection of retractor nozzles includes units with spring or compressed air retraction. Nozzle extension in these devices is usually accomplished via fluid pressure. Retractors can be equipped with static spray balls, Chemidisc and Chemitorus series slide bearing nozzles, and high-speed rotating ball bearing nozzles. The position of a retractor nozzle (open/closed) can be checked by means of a magnetic sensor. Our retractors can be adapted to individual needs. Depending on the device type, FDA conformity as well as EX exemption and stroke widths between 50 mm and 1000 mm are possible.

The RETRAKTOR MR1 is a retractable spring-based retractable cleaning nozzle used primarily in the food, chemical and pharmaceutical industries. Using a fluid pressure of 3 bar, a rotating nozzle extends up to 300 mm into a container, pipe or equipment, allowing for targeted 270-360° all-around cleaning. The MR1 can be equipped with different nozzle sizes and types, allowing adjustments in terms of liquid flow rates or effective area. The rotating nozzle itself is fluid-bearing and extremely durable. There is a choice between a closed system (shown) or an open system without closure to the production area.

The MR1 guarantees continuous self-cleaning during operation and can be supplied with compressed air or steam after use for complete emptying, drying or sterilization. The compressed air or steam supply must counteract the spring to achieve easy opening; complete opening is not possible. The MR1 can be used in containers with low negative pressure.

A function control can be optionally realized via magnetic proximity sensors. For mounting an MR1 to a vessel or pipe, different mounting types starting from 2.5″ (DN65) are possible.

The MR1 is completely made of stainless steel 316L (spring AISI316) and equipped with solvent and temperature resistant plastic components. The MR1 retractor is FDA compliant and suitable for hazardous areas (ATEX94/9/EC) and for use with flammable liquids.

The MR1 retractor can be used for liquid injection or cleaning of vessels, pipes or areas in production or filling plants.
