Leading industrial laundry, Servizi Ospedalieri, is fulfilling its environmental pledge of reducing energy usage by installing the award winning GEM venturi orifice traps from Thermal Energy International. Trialled through Thermal Energy International’s Italian agent, Nuova Folati, at Servizi Ospedalieri’s plant in Porto Garibaldi, the laundry’s independent, technical assessors, IMAT S.r.l. of Rome, was able to verify that GEM steam traps have provided close to a 10% saving in energy consumption compared to newly installed mechanical traps.
Steam is used extensively throughout the laundry in the operation of tumble dryers, steam presses, dryers, ironing, wrapping and sterilisation. Prior to the installation of the GEM venturi orifice steam traps, Servizi Ospedalieri found its mechanical traps were failing open, closed and partially open.
As the traps were not regularly inspected, it was often sometime before it was found that the mechanical traps was not working, by which time the failed open steam traps were impacting on steam production by not returning condensate back to the boiler. This was costing the company 250 euros a month for each failed steam trap.
Looking for a solution to the problem, Mr. Bensi, Purchasing Manager, and Mr. De Marco, Technical and Production Manager at Servizi Ospedalieri, who had read about the GEM steam traps, decided to conduct a trial to evaluate the efficiency of the GEM trap against new mechanical traps using identical monitoring times and conditions. This was undertaken by NUOVA FOLATI/IMAT using a Vortex steam meter to measure the steam consumption of one of the main laundry’s steam processes.
The steam metering results were crucial in this exercise and confirmed that the laundry achieved almost 10% reduction in steam. These savings will provide the laundry with a very short-term payback and in addition it will have the added bonus of almost zero maintenance and a 10-year guarantee on the traps.
Instead of utilising a valve mechanism to close off steam, the highly efficient GEM steam traps use the patented venturi orifice design to effectively drain condensate from the steam system. As the GEM steam traps have no moving parts to wedge open or fail, it provides the ultimate in reliability necessitating only minimal maintenance and requiring no spares, testing or monitoring equipment.
Available in a wide range of sizes for a full cross section of applications, the hardwearing GEM steam traps are manufactured from corrosion resistant stainless steel and are guaranteed for 10 years, obviating the need for repair or replacement. The GEM steam traps provide a fast payback - on some processes within a matter of days - from reduced energy costs and increased equipment reliability due to a reduction in damaging steam within the condensate system. In addition it improves product processing by enhancing the quality of steam which in turn reduces equipment repairs, downtime and replacement costs.
