An ice resurfacer is a vehicle or hand-pushed device for cleaning and smoothing the surface of a sheet of ice, usually in an ice rink. The first ice resurfacer was developed by American inventor and engineer Frank Zamboni in 1949 in Paramount, California. [1] As such, an ice resurfacer is often referred to as a "Zamboni" as a genericized trademark.
Pumpable ice technology (PIT) uses thin liquids, with the cooling capacity of ice. Pumpable ice is typically a slurry of ice crystals or particles ranging from 5 micrometers to 1 cm in diameter and transported in brine, seawater, food liquid, or gas bubbles of air, ozone, or carbon dioxide. [1] [2] [3] Pumpable ice passed through plastic tubes
Then, in 1949, he invented a machine that transformed the job of resurfacing an ice rink from a five-man, 90-minute task to a one-man, 15-minute job. [4] The initial machine included a hydraulic cylinder from an A-20 attack plane , a chassis from an oil derrick, a Jeep engine, a wooden bin to catch the shavings, and a series of pulleys.
Such a system usually runs in ice-making mode for 16 to 18 hours a day and in ice-melting mode for six hours a day. Capital expenditures are minimized because the chillers can be just 40 - 50% of the size needed for a conventional design. Ice storage sufficient to store half a day's rejected heat is usually adequate.
Moscow, Russia "circus on ice" portable rink. The "Winter Garden" arena in Ridgefield, Connecticut. The arena has a conventional ice rink which is closed in the summer, while a 2,600-square-foot (240 m 2) synthetic ice rink is used year-round for youth hockey training and public skating. [19]
Having invented the ability to create a portable ice rink, Chalfen's Holiday on Ice could set up anywhere in the world and perform independent of permanent standing ice rink facilities. As a result, Chalfen became the only international American ice show, the first to play behind the Iron Curtain (during the Cold War), China, and around the globe.
