Look for the presence of hydraulic fluid in the cooling water, or water in the
hydraulic fluid. MTS has water-in-fluid and fluid-in-water sensors available to
aid in the early detection of contamination of your cooling water or hydraulic
fluid. Contact MTS for more information.
Replace the heat exchanger at the first signs of a problem. If you wait for a
catastrophic failure, you will contaminate the entire cooling water supply, ground
water or hydraulic system and face expensive cleanup costs and the loss of
valuable time that could be devoted to testing. If the ground water becomes
contaminated, your company may face severe penalties and cleanup costs for
environmental damage. If you have several pumps on the same hydraulic supply
line, you risk damaging them and incurring the added expense of repairing
several heat exchangers and hydraulic power units.
