Frame structures for the food industry and in clean rooms

RK Rose+Krieger has developed the EMS stainless steel connection elements which can be used in conjunction with special clamping technology to assemble and disassemble frame structures for food industry and clean room applications, made from square or round tubing in the common size 40 quickly, reliably and without the need for specialist knowledge.

EMS provides an alternative to welded connections, which is an extraordinarily labour-intensive process. With EMS, the customer receives fully machined connection elements, including innovative clamping technology which can be combined with cut-to-length stainless steel tubes to form any kind of frame or railing.

The special cast stainless steel clamping connectors are able to offset tolerances of up to 2mm. They are inserted into the tubes and the EMS connection elements, and firmly clamped in the tube by tightening a screw. This creates a secure connection which, at the same time, can be released at any time.

The connectors for round pipes consist of two half-shells that are braced in the pipe by tightening two Allen screws that press against each other. Ribs on the conically bevelled outer radius of the connectors are the first to press. Unlike conventional connectors, the EMS round connectors always have contact at four points in the pipe due to their special design. This prevents ‘tipping’ and ensures a secure, centred all-round fit.

When connecting square tubes, the special design of the clamping connectors guarantees that uniform pressure is applied in all four directions. This ensures an integrated inclined plane through which the two half-shells interlock and thus stabilise. By spreading the half-shells diagonally with the help of two Allen screws, the geometry of the component creates six contact surfaces. This guarantees secure bracing.

There are currently five different EMS elements available for delivery: corners, T connectors, cross connectors, 3-stream connectors and base elements with adjustable foot connection. In addition to the tapped hole – for screwing in the adjustable foot – the EMS base elements also have a second drilled hole which can be used to drain cleaning fluid.
