When it is apparent that dozens of solutions to the need for a vacuum system are potentially feasible, Nash engineers utilize their expertise to search out the best alternative. We investigate with our customers the economics of valuable product recovery. We take into account such environmental considerations as disposal of unwanted process carryover. We find ways to conserve power, water and heat energy. We evaluate system arrangements, scheduled maintenance and service life. We analyze available ratios of first cost to operating costs, so that our customers can tailor those two different types of expenditures to their company's financial objectives. In summary, what Nash does is supply Engineered Systems designed to solve customer problems. Some of the industries we work in can be explored below.
