Cooling Towers

The best new market that Redwood has found in years, they say, is cooling tower materials. The use of wooden cooling towers has spread and is continuing to spread in startling fashion, not only in this country, but att bver the industrial world, wherever water is worih money.

A cooling tower is a scientifically constructe-d wooden structure like the one illustrated herewith. used exclusivelv for the cooling of water so that it may be used and usef over and over again, instead of being used once and then wasted. In arid territories where water is scarce and precious, cooling towers are absolutelv indispensable; and even in territories not arid where watei is needed in large quan- tities and the one-time use of this necessity runs -into big money, cooling towers pay a big profit on the investment-.

_ Water is used, then pumped or siphoned to the top of this wooden structure, where it makes a series of water-falls in getting back to plant level again, and is then used over again. It is cheaper and much more practical than any possibility of storage tanks, and the water is better fitted for re-use. In many cases the loss of water with each reuse is only a small percentage, and in arid territories the saving of water pays for the cooling tower in a very short tlme.

This is Redwood's newest and one of its best customers, and one that will undoubtedly grow steadily. The rotresisting qualities of Redwood make it ideal for this use, and seve-ral_big firms in California specialize in the design- ing and building of cooling towers of Redwood, of all siies.
