The Redditch-based UK arm of Precia-Molen has recently supplied A-Gas (UK) with weighing systems for three vertical storage vessels plus a platform scale for gas cylinders. The company is based in Portbury West, Bristol, and operates as an international business in the distribution of speciality chemicals such as refrigerants, insulation agents, industrial gases and other products including propellants and solvents. The project involved the supply of weighing systems for three large vertical storage vessels in an area classified as a Zone 2 hazardous area (according to the ATEX Directive), with the platform scale located in a safe (non ATEX) area.
For the installation Precia-Molen supplied 12 Silo LoadMounts with ATEX certified model 460 load cells providing a four-cell arrangement for each vessel, offering better stability under high wind-loads. Manufactured in stainless steel and sealed to IP68, the assemblies were delivered ‘locked up’ allowing the erection of the vessel directly on to the mounts without the need for dummy load cells during installation. Each vessel is equipped with an ATEX-certified weight transmitter Model I400 TB EX 2-21 which is connected via a high-speed data bus to an I 400 D-MS Operator terminal located in the safe area adjacent to the cylinder scale. www.preciamolen.com
