The Bel-Art Economy Frigimat portable dry ice maker, European model number 388760002 by Scienceware, has a low-density polyethylene chamber for strength and chemical resistance for molding dry ice. Dry ice is used to keep a substance or object cold in food handling and shipping, science, and medical applications, and is used to create a fog-type of atmosphere in the entertainment industry. This dry ice maker is good for use in remote locations or where there is limited availability of commercially prepared dry ice. Its chamber is secured into place by a metal clamping mechanism for reliability. A 50-lb. cylinder of liquid carbon dioxide ([LCO2] sold locally, separately) with dip tube makes eight 454-gram (sixteen ounce) blocks of dry ice. Each block measures 10.4 (l) x 9.2 (w) cm, and is produced in approximately one to two minutes. The dry ice maker features a porous polyethylene diffusion plate to vent excess gas, and a built-in gas pressure gauge with relief valve to monitor and prevent pressure build-up for safe operation. Its epoxy-coated steel frame has four non-skid rubber feet at its base to prevent sliding.
This dry ice maker includes a 1.8-meter (6-foot) nickel-plated copper connecting tube with standard CGA 320 (0.830-inch to 14-inch) thread couplings for attachment to an LCO2 cylinder (not included). It is a European model for direct connection to an LCO2 tank. Threads on the LCO2 tank (supplied by the tank manufacturer) must match the European model. Dry ice must be handled using insulated cryogenic gloves (sold separately). The dry ice maker’s dimensions are 37 (l) x 15 (h) x 14 (w) cm [14-3/4 (l) x 6 (h) 5-1/2 (w) inches], and it weighs 7.9 lbs. with valve attachment. Dry ice temperature is -109.3 degrees F (-78.5 degrees C).
Dry ice, the solid form of carbon dioxide (CO2), is commonly used as a cooling agent when temperatures lower than conventional ice are desired, and liquid melt-water is not desired. Dry ice is made by compressing and cooling the gas form of CO2 until it liquefies. With expansion, the liquid changes into a solid state, and is then hydraulically compressed into dry ice blocks, pellets, or slices. Rather than melting, dry ice sublimates, turning back into gas, as the temperature rises. Under specific conditions, dry ice can create a fog-like effect. It is much heavier than frozen H2O, and should be handled using insulated cryogenic gloves for thermal protection. Dry ice is used in laboratory, and field applications in the fire-fighting, food handling and shipping, medical, science, education, industrial cleaning, and entertainment industries.
Since 1946, Bel-Art has been manufacturing and distributing scientific equipment such as lab ware, dry ice makers, desiccators, glassware, testing equipment, and safety supplies for the scientific and medical industries. With worldwide distribution, and facilities located in New Jersey, Maryland and Missouri, most Bel-Art products are manufactured in the USA. Bel-Art is the recipient of numerous awards, including the Presidential “E” Award by the US Department of Commerce for excellence in export sales.
