ENCLOSURES & ENCLOSURE FURNITURE SUPPLEMENT


individual components has not had a noticeable effect on the available space within enclosures, mainly because this is largely determined by the arrangement of the DIN rails, cable ducts and other components. Components are frequently installed in groups and space can only be marginally optimised by individual components. “We would caution that where space is taken up by smaller components, users should review climate control because higher packing densities increases the overall risk of hotspots. The good news is this doesn’t have to be a laborious task because Rittal’s ‘Therm’ application performs the calculation of climate control in its entirety, providing users with appropriate and correctly dimensioned solutions.”


DISTRIBUTED SYSTEMS Major distributed systems are commonly found in the petro-chemical industry and conveyor systems. They employ less technically advanced enclosures to house control equipment in a separate room. However, the cost of cabling to connect to the machinery can be high. Rittal’s range of enclosures includes


amount of cabling needed and this type of locally-employed enclosure distribution is often more efficient because of the specialist protection it provides against dust and oil. In other, highly sensitised environments such as the food industry where hygiene standards must be met, users now have a choice of both the materials used and the enclosure design, in order to prevent contaminants being deposited and simplify cleaning.

COMPACT MACHINES AND DECENTRALISATION In decentralisation, the focus is around making machines as compact and centralised as possible, in order to make it easy to commission them. Machines can be assembled as complete transportable units, but the control technology for the machines needs to be in the right place. This can be done either by machine-integrated standard enclosures or through the appropriate integration in the body of the machine. Metcalfe advises:


“We have products, accessories and expert


advisors who can advise around protection category, heat


models with high IP ratings in sheet steel, stainless steel or plastic, designed to protect the equipment housed in it. This means that, rather than putting the control gear in a separate room, all the control gear can be next to the machine itself. This offers cost savings around the


dissipation, EMC (electro-magnetic compatibility) and the corresponding installation regulations and requirements, which all have to be taken into account.”

AUTOMATION SYSTEM DELIVERS MAJOR BENEFITS


When the directors of Peterborough-based panel builders Pneumatechnique were looking at ways to improve efficiency and offer better production consistency, they turned to Rittal and its automation systems for switchgear construction. Pneumatechnique’s aim was to find ways to lower both overheads and operational costs. One of the main issues the company faced was the underemployment of their highly skilled labour force. This had become obvious during an evaluation of work practices that considered how they were meeting customer demand, and how the company in turn made demands on production as an ‘internal customer’. Following a detailed assessment and recommendations


made by Rittal’s expert team, the decision was taken by Pneumatechnique to install a Rittal Automation Perforex CNC machine. Rittal’s team was able to advise on both the benefits that


would be realised by installing the system, and potential limitations. It was quickly identified that the capital expenditure could clearly be outweighed by the cost savings and the Perforex installation became a ‘no-brainer’ as part of the investment project. Adam Wilson, production manager at Pneumatechnique, advises: “The Perforex System has improved the quality, consistency and speed of our output, which has obviously been hugely beneficial for customers. A project that was taking four hours can now be completed in just 20 minutes and with a better finish.”
