| 02/08 Compressed Air Industry BULK HANDLING | DEKKER VACUUM Most of the systems that we design and manufacture require a level of innovation. Dekker is an engineering company, heavily invested in application and design engineering. Each customized application essentially involves designing a new product. Customer satisfaction is extremely high when we are able to tailor a solution for them, rather than offer them a standard product. Innovation also takes place within our organization to create the most efficient processes to handle our day-to-day business. We are also investing in a pipeline of exciting new products. They involve new control schemes and dry (oil-free) vacuum technologies. What markets do you serve? VmaxVFD Variable Frequency Drive oil-sealed liquid-ring vacuum system used in the medical and woodworking industries. We are in many markets but to name some of the big ones — plastics, woodworking, medical, general industrial, power generation, chemical, petroleum and pharmaceutical. Where are the energy efficiency opportunities with vacuum? At Dekker, we are very committed to energy efficiency. One of our primary areas on focus has been in promoting the use of variable frequency drives (VFD’s). We have sold close to a hundred systems with VFD’s. The woodworking industry, with CNC routers, is a good example. As you start routing a board, you are creating leakage as the router cuts through the plywood board on the router table. The more you cut, the more leakage you create and the part can slip, which increases scrap rates. As you create more leakage a VFD system will ramp up the speed of the vacuum pump to keep the part from slipping, reducing scrap. Energy consumption is also reduced due to the elimination of across the line starting and speed turn down when idle. Another application is in the power plant industry. Upgraded vacuum systems can improve the efficiency of the turbine by reducing backpressure. This is accomplished by removing the air leakage in the condensers. Customers may realize energy savings between $250,000 AquaSeal PowerGen condenser-exhauster two-stage liquid ring vacuum system used for Power Industry to reduce main turbine back pressure. 38 www.airbestpractices.com http://www.airbestpractices.com
