Compressed Air Industry BULK HANDLING | 02/08 | and $1 million per year. Savings are naturally dependent on a number of factors, including condenser cooling water temperature and the age or type of vacuum equipment currently in service. The use of VFD’s requires a certain level of electrical integration, especially when multiple VFD’s are used such as in Hospital applications. At Dekker, we have a dedicated electrical engineering department, which has developed proprietary control algorithms. Such a focus on electrical engineering is somewhat unique in our industry. This department is also developing some exciting, innovative products that will be launched in the coming year. Full plant audits of vacuum systems are also a growing trend. Piping networks have pressure drops and leaks like in compressed air distribution systems. Many machines using vacuum are not receiving it at the optimal pressure. Centralized vs. de-centralization issues — there are a lot of opportunities out there. Industry can save thousands of dollars by shutting down an air compressor and switching to mechanical vacuum pumps. We also suggest that all packaging companies using venturis (air ejectors) should examine the benefits of switching to mechanical vacuum pumps. While the benefit of a venture is no moving parts, the energy inefficiency overshadows that benefit. Venturis require a lot of compressed air to create vacuum. Using a mechanical vacuum pump will require 1⁄4 to 1⁄8 the energy used in creating vacuum with a venturi and compressed air. From an energy efficiency perspective, this is very easily justified. CO2 O What is the scope of product offering? Our product range is from 2 acfm to 28,000 acfm. Vacuum levels range from 10 inches of mercury to 1 Tor. We offer liquid ring and rotary vane vacuum pumps and systems. The rotary vane pumps are both dry and lubricated. The dry pumps are truly dry pumps, with no oil in the vacuum pump. We have found a lot of issues in the market as suppliers try to deliver “oil-free” dry vacuum pumps. Most “dry” pumps out there still end up with some oil in the pumping chamber as oil migrates from the gearbox through the seals into the pumping chamber. To help us serve our customers better, we stock over 1,000 pumps and 85% of bare pump orders ship within 24 hours. We have a full metal fabrication workshop for base plates, tank fabrication and Section 9 pipe welding. We design, fabricate and assemble the complete systems and perform the electrical work and controls programming. Every system is full tested prior to shipment to ensure a satisfied customer. Power Plant customers may realize energy savings between $250,000 and $1 million per year with upgraded vacuum systems. Thank you for your insights.
