Planning your lab construction or renovation around VACUU•LAN® networks can offer many economies.
- Right-sizing: The modularity of the VACUU•LAN® network avoids the temptation to oversize installations, minimizing capital and installation costs. You put VACUU•LAN® networks only where the need for vacuum is clear, taking advantage of the modularity of VACUU•LAN® technology to ensure that vacuum will be available wherever needed in the future.
- Labor savings: Installation is done with light, corrosion-resistant PTFE tubing with compression fittings, instead of the welding or brazing and skilled labor needed to install the rigid tubing for a central system.
- Reduced capital costs: One vacuum pump can serve up to 8 or 10 workstations in a lab, so you avoid the cost and space consumption of multiple dedicated vacuum pumps.
- Avoided duplicate investment: Vacuum available at each port on a VACUU•LAN® network is comparable to that available from a high-performance, oil-free vacuum pump. Many buildings equipped with central vacuum systems pay double for vacuum supply: once for the central system which provides a low-grade, filtration quality vacuum to every port, and then to purchase a dedicated vacuum pump capable of 5 mbar or less for high-boiling-point solvent applications, or an electronically controlled pump at workstations where critical evaporations are performed. VACUU•LAN® technology provides all three types of vacuum form a single network, avoiding the investment duplication.
- Reduced water costs: Compared with water jet aspirators, a VACUU•LAN® network can reduce lab water consumption by tens of thousands of gallons of water per year per lab, saving on pollution and treatment costs.
- Energy savings: Vacuum pumps that are appropriate for a central vacuum system handling corrosive vapors need to operate 24/7/365, with the associated energy consumption and maintenance demands. In contrast, the demand-responsive operation of a VACUU•LAN® network can save 70 to 90 percent of the energy associated with the 24/7 operation typical of central vacuum systems, while still providing exceptional chemical resistance.
- Reduced solvent waste: Vapor capture with VACUU•LAN® network server pumps designed to condense and collect solvent vapors can lower solvent disposal costs. Vapors can be captured in the lab before mixing (unpredictably) with vapors from other labs, can be recycled for reuse, or can be kept separated from other waste solvents, reducing the volumes that must be treated as costly hazardous materials.
- Reduced service demands: Recommended service intervals for VACUUBRAND oil-free vacuum pumps used as server pumps for a VACUU•LAN® network are 10,000-15,000 operating hours. In a lab that uses vacuum 40 hours a week, the first recommended diaphragm change — an operation that takes less than an hour — occurs some 5 years after initial use. There are no regular oil changes to schedule and remember — or any oil changes, for that matter! For a lab that uses vacuum less intensively, the systems are practically maintenance free.Fluoropolymer diaphragms in the VACUU•LAN® pumps are chemical resistant, and so tolerate well the vapors common in a science building vacuum system. Contrast that steady reliability with the regular maintenance needed in the liquid ring pumps common in central vacuum system pumps, or the susceptibility to corrosion typical of claw pumps when used for scientific vacuum systems, and the dramatically lower lifetime costs of operation with a VACUU•LAN® network are clear.
