"Once we started flowing all the water, the mist from all the trucks, all those hoses and stuff just started icing up and made for very miserable conditions - walls of ice," he said.

This is one of the reasons that scuba regulators are generally constructed from brass, and chrome plated (for protection). Brass, with its good thermal conductive properties, quickly conducts heat from the surrounding water to the cold, newly decompressed air, helping to prevent icing up.

251 The heating system would eventually be given the moniker Lombardi's Folly. The prior convention to prevent the football field from icing up was to cover the field with dozens of tons of hay.Gruver, 2002 pg. 21 The Wisconsin State University–La Crosse (now the University of Wisconsin–La Crosse) Marching Chiefs band was scheduled to perform the pre- game and half-time shows.

Most locking carabiners are based on the solid gate design. # Wire gate: A single piece of bent spring-steel wire forms the gate, with no separate spring or pins needed (it is a form of 'living hinge'). Wire gate carabiners are significantly lighter than solid gates, with roughly the same strength. Wire gates are less prone to icing up than solid gates, an advantage in Alpine mountaineering and ice climbing.

After 18 hours, The Spirits wings and engine begin icing up and the aircraft begins losing altitude. Lindbergh changes course and the ice breaks off in the warmer air and the engine, which has stopped due to icing, is restarted. Back on course, his compasses begin malfunctioning, forcing him to navigate by the stars. By dawn, "Slim" falls asleep, and the monoplane slowly descends in a wide spiral toward the ocean.

Cooling water from the engine and compressor was fed into the boiler at about 70°C. For cold starting, the boiler was used to preheat the diesel engine. When the locomotive started from rest, the original steam cylinders were fed with steam alone, but when running they were powered by a mixture of steam and compressed air. The steam was needed to prevent the cylinders icing up, because compressed air cools when it expands.

During this period the 578th Infantry and its attached and much weakened engineers advanced less than a block on the left flank of the 650th Regiment along the Volga. Meanwhile the river was rapidly icing-up, blocking supply traffic to 62nd Army from the east bank. On November 17 Hitler sent a new order to 6th Army stating that the ice presented an opportunity to reach the river, specifically in the Barrikady and Krasny Oktyabr sectors.

In 1943, tests were done on adding a muzzle heater to the barrel of the 15cm TbtsK C/36 gun, in order to prevent the barrel from icing up in freezing temperatures, but this was abandoned when it was found that it both would consume too much electricity, and put too much strain on the mount's elevating gear. The gun cradle was made of a hollow tube, two hydraulic buffers which could absorb a recoil force of up to , and a pneumatic recuperator.

The weather conditions had caused the "Uiver" to drift a long way east of its intended course; the "Uiver" should have crossed the Murray River near Echuca. With two-way radio communications lost because of the storm, it had not been possible for the drift to be corrected. After passing over Albury, the "Uiver" made at least two forays towards the mountains of the Great Dividing Range, before returning to the lights of Albury. Icing up of wings and propellers had made passage to Melbourne impossible.

When selected with the optional "cold coalescing filter", these units can deliver compressed air with lower dew points. Non- cycling dryers use a hot gas by pass valve to prevent the dryer from icing up. Some manufacturers produce "cold coalescing filters" that are positioned inside of the air dryer at the point of the lowest air temperature (the point at which maximum condensation has occurred)., Refrigerated dryers are generally manufactured in one of two different ways, Freon based units and Joule-Thomson based units.

New York Times - August 21, 1915 article titled "Mrs. G. D. Widener Opens New Villa" The 27-bedroom, 14-bath mansion has a 27' × 63' Grand Salon/ballroom on the first floor which opens onto a oceanfront terrace. Among its other features, the mansion has a 10,000-bottle wine cellar with a 20-ft (6 m) stone basin for icing up to 200 bottles of champagne at once.Bloomberg News - November 10, 2006 The property features includes a carriage house and gardens with a bronze fountain designed by French sculptor Henri-Léon Gréber, father of the landscape designer.

This problem is reduced in rebreathers because the soda lime reaction, which removes carbon dioxide, also puts moisture back into the breathing gas. In hot climates, open circuit diving can accelerate heat exhaustion because of dehydration. Another concern with regard to moisture content is the tendency of moisture to condense as the gas is decompressed while passing through the regulator; this coupled with the extreme reduction in temperature, also due to the decompression can cause the moisture to solidify as ice. This icing up in a regulator can cause moving parts to seize and the regulator to fail or free flow.

To prevent the pre-coolers from icing up, the first pre- cooler cooled the air to around 10 degrees above freezing point, to liquefy the water vapour in the air. Then LOX would have been injected into the airflow to drop the temperature to flash freezing the water into microscopic ice crystals, sufficiently cold that they wouldn't melt due to kinetic heating if they struck the second pre-cooler elements. A water trap could have been added after the first pre-cooler if operating conditions resulted in an excess of moisture. When it was no longer possible to use the atmosphere for combustion, the RB545 would switch to using on-board liquid oxygen (LOX) to burn with the hydrogen as a high-efficiency hydrogen/oxygen rocket.
