In two weeks, the new solution
"The whole conversion had to be done on company holidays," recalls Meier plug. "That means we have only two weeks time." The ALMIG dismantled at this time the old system and the unused pipes and ventilation ducts featured on the new equipment, supplied and installed new plumbing, fitted to the ventilation ducts and care is the ventilation system. The old piston compressor unit powered while the rest of the work operation.
In the course of the project was re-measurements ALMIG different. "At the beginning of the project we were determined using a fixed consumption profile, a compressed-air ratio of 1.989 cents per cubic meter of air for the plants. In the comparison measurement, the consumption profile had changed, however, to our disadvantage, "says Meier plug. The old usage profile included a very strong phase at medium power. In comparison with the measurement of new plants during the day shift, there was suddenly a strong and a brief period of high demand and in the night shift, a very low minimum consumption in terms of spare parts for piston compressors. "Nevertheless, we managed to reduce energy costs, thus reducing the air pressure ratio at 1.286 cents per cubic meter," says Meier plug. Because the new system minimizes leakage and drainage losses. In addition, the process was optimized. Although now the period of low load phase is more pronounced, and the compressor does not run at the optimum operating point, does this affect the overall energy balance is not negative.
Amortized in two and a half years
The winery is now with the new compressor energy savings of 23,000 €. Due to the heat recovery can be saved another 11,000 €. The total investment amounted to € 80,000. With the current cost-saving and heat recovery, the new compressor in less than two and a half years have paid off. What is more, the maintenance costs are much lower compared to the old systems spare parts for piston compressor. Maintenance accounts for V-belts. In addition, the new facilities external Ölabscheidepatronen. That makes more assembly work on the oil tank caps unnecessary.
The normal service interval for these compressors is located at 4000 Hours. By nature, the controls are equipped with an accounting monitoring system. Service technicians, but also Langguth Erben employees can read the running of the last days of operation or the operation last week and it see how much the compressor is utilized and whether there are reserves. "If we determine that the performance has changed significantly, it can respond immediately Langguth Erben flexible." Says Meier plug.
