A-Series switches have proven reliable in: ? Offshore oil rigs, where stainless steelconstruction and small size is desirable? Chemical and petrochemical plants,where small size and explosionproofconstruction is important ? Pulp and paper mills on equipmentwhere corrosion resistance and sealed contacts extend life? Special equipment such as autoclavesand sterilizers, where special connec- tions are needed ? Food and pharmaceutical applicationswhere sanitary connections are required? Rail and heavy vehicle hydraulic andpneumatic braking applications, where small size is an advantage? Other special machinery and equip-ment applications, where small size and high performance are desirableTypical applications include: pumps, com-pressors, washers, industrial filters, degreasers, industrial evaporators, recovery systems, foodprocessing, ground support equipment,reverse osmosis systems, industrial heat exchangers, hydraulic systems, lubrica- tion systems, marine equipment, textile machinery, heating and air conditioning equipment.
