The University of Reading er begyndt at opnå vand- og energibesparelser på sit Bio Food Hall i Food & Nutritional Sciences Department efter installationen af to Busch RA oliesmurte lamel pumper for vakuum kredsløb. Ifølge universitetets Energi manager Dan Fernbank, da de to pumper blev installeret af AxFlow tidligere på året, vandbesparelser på mellem 20 og 30m³ per dag bliver nået, hvilket er hvad der svarer til mellem 7,000m³ og 11,000m³ årligt.
Universitetets Fødevare- og Ernæringsvidenskabelige Afdeling er den eneste britiske universitetsfacilitet med en fuldt udstyret fødevareforarbejdningshal og har adgang til mange specialiserede analytiske forskningsredskaber. Vakuumkredsløbet er et grundlæggende krav for alle laboratorierne, og rørsystemet løber rundt i bygningen, hvilket gør det muligt for de forskellige laboratorier at trække fugt på bestemte punkter.
“The two Busch pumps which we supplied replaced two vacuum pumps which had been operating since the building was opened in 1985,” reports Andy Woods, Sales Engineer, AxFlow. “The original pumps had water running through them at a rate of 12 litres per minute for the purpose of cooling, but because it could not be re-circulated, the water was allowed to drain away. By calculating the volume of water being wasted and its cost to the University, a decision was taken to remedy the situation. It was shortly after this that AxFlow Windsor was called in to make a recommendation on replacement pumps.”
The replacement Busch oil lubricated pumps do not require water cooling, thereby eliminating any need for water. A further attraction of this pump type is that it is more energy efficient. “We offered the University two options, a liquid ring vacuum pump with partial seal water recirculation and the oil lubricated rotary vane pump,” continues Andy Woods. “Although the second option will require regular servicing, the efficiency savings meant that this option was selected and we went ahead and removed the old pumps and installed the new ones in March.”
In terms of water saved, Dan Fernbank reports that this will account for the equivalent of 3% to 4% of the university’s total annual water consumption. “In financial terms, this equates to between £12,000 and £18,000 annually and being a more efficient pump, it is also saving around £1,000 in electricity,” comments Dan. “It is therefore a major step in our drive to cut our water consumption by 10% and carbon emissions by 35%.”
AxFlow offers a comprehensive range of engineering resources to facilities management, environmental and process industries. The Windsor Service Centre operates teams of mobile service engineers for on-site maintenance across the southern half of England, supported by workshop personnel and design engineering resources. “Our Windsor operation is very much geared up to providing support in the building services sector and we offer a wide range of capabilities,” says Bob Jervis, Sales Manager. For instance the repair and servicing of air-handling equipment can involve the replacement of bearings, motors, pulleys and belts, as well as the re-balancing of the fan impeller assembly. We can also carry out the repair or replacement of cooling and heating coils within the AHU’s.
