High Water Content Fluids


High water content fluids (HWCF) as a class separate from fire resistant fluids came into prominence in the 1970s, mainly as a replacement to mineral oils. The oil crisis of the early 1970s fueled the R& D work on HWCF with a view to conserving petroleum products. Automotive industries in the U.S. [1–3] looked at this crisis as an opportunity to find a replacement to mineral oil with a less expensive and easily available fluid, as U.S. automotive industry's consumption was as high as 3.5 million liters per annum. Automotive industries, machine tool builders, hydraulic fluid and hydraulic hardware manufactures charted a development program to make HWCF a viable alternative fluid to mineral oil. The initiative taken at that time did bear fruit, and today HWCF is here to stay, though its application is not as wide as was envisaged.
