Two Anhydrous Tanks Converted Into Pressure Washer, Diesel Fuel Carrier
Fred Roth, Carlinville, Ill., converted two old anhydrous tanks for other uses on the farm. He turned a 500-gal. tank into a giant pressure washer that he uses to clean equipment right in the field. A smaller 250-gal. anhydrous tank was mounted to a portable diesel fuel tank so he can refuel tractors in the field.
The converted tanks mount together on a 2-wheel trailer that he pulls behind his pickup.
"The pressure washer is the handiest thing I've ever built," says Roth. "I put 120 lbs. of pressure in the tank so it has plenty of cleaning power. I often use it right out in the field to clean the radiator on our Caterpillar dozer. We have an earlier model Cat dozer, one where the air is forced forward into the radiator which causes dirt to build up in it. We also use it to clean our tractors and trucks."
To convert the tank to hold water, Roth simply hooked up a water hose to the liquid side valve on the tank and then fitted the tank with an air valve. A small compressor is all that's needed to pressurize it.
The smaller anhydrous tank carries diesel fuel under very low pressure. It's fitted with a big diameter, 20-ft. long hose to transfer fuel to the tractor. Fuel is pumped through a large see-through fuel filter as it enters the hose. An air hose runs from the "vapor" side of the 500-gal. tank to an air valve on the fuel tank. The air pressure pushes the fuel out of the tank.
"It holds enough fuel to keep two tractors going for 2 or 3 days before we have to take the tank home and refill it," says Roth. "The valves have a 1-in. outlet so it takes only about 3 minutes to fill a 30-gal. fuel tank. There's less than 5 lbs. of pressure in the fuel tank. The tank works great because I don't have to do any pumping by hand or rely on a 12-volt battery.
"I paid $25 for the big anhydrous tank and already had the smaller tank. My total cost including tanks, hoses, and fittings was about
