INTEGRATED SYSTEMS Cost-effective diaphragm seals protect from extreme heat When manufacturers of commercial catering equipment are looking for standard components with high-quality style and robust ergonomic execution, they are likely to find the growing Elesa range highly suitable. The company’s expanded series of standard and custom bridge handles being a case in point, and especially compatible with ovens, combination ovens, microwave ovens and other worktop preparation and storage equipment. Usually being held with one hand while the other is occupied, these handles are also used on standalone heating cabinets and refrigerators, which call for high quality handles with concealed fixings. Competitive market Commercial kitchen equipment manufacturers operate in a small and very competitive market – a true niche where quality and design are major differentiating factors. This type of equipment requires handles that are simple, elegant, quick, and easy to use and clean, for doors and other opening panels. Modern equipment styling in stainless steel and glass calls for compatible hardware to match and incorporating top- quality production values that ensure long service life. They are usually required to withstand multiple daily cleaning cycles, often using aggressive chemicals and equipment e.g. brushes, hoses and cloths. The Elesa EBP series bridge handles in reinforced technopolymer fits the need for a small bridge style handle and is also available in a sanitised version (SAN) with silver ion inclusion. For lifting of bench top equipment or handling of large removable panels the series EPR offer a simple solution with multiple colour options. Where style and colour are important then the larger ETH bridge handles in Technopolymer and aluminium provide an ergonomic solution. For heavier duty stainless steel equipment, the Elesa GN 333.6 are highly finished and highly functional to match modern clean designs of kitchen equipment for all levels of professional installations. These Elesa handles offer excellent haptic properties that are easy to grab in a hurry and provide a positive “feel” so that the operator has confidence that the equipment will open and close comfortably, as expected, day after day. www.elesa.com Elesa quality handles for commercial catering equipment Testing and measuring pressure at high temperatures is a challenge that many companies face. Among others, applications in food processing, automotive and steam may require instruments that stand up to temperatures far above typical ranges. Because the temperature is so high, the options available to companies to measure and test pressure are often limited, leading many to choose simple pressure sensors. For companies looking to complete more advanced analysis, like data recording, this can be a challenge. AMETEK STC has a solution in its M&G line of reliable diaphragm seals. The M&G diaphragm seals provide a barrier between the heated pressure source and the advanced instrumentation. Adding this barrier allows companies to use their instrumentation of choice rather than only those capable of direct high-temperature connections. The M&G Type E Diaphragm Seal includes a temperature rating up to 250degF or 121degC and supports pressure up to 5000 psi (345 bar). Its all-welded, 316L stainless steel construction contains no gaskets or bolting, removing the most common leak points. In addition to protecting instruments from high temperatures, diaphragm seals also protect against caustic chemicals and pressure spikes. Operators may recover the initial investment of a diaphragm seal by reducing production downtime, extending the service life of instrumentation, lowering the cost of repetitive instrument installation, and reducing or eliminating maintenance costs. www.ametekusg.com www.ametekcalibration.com 50 HYDRAULICS & PNEUMATICS January/February 2022 www.hpmag.co.uk
