Le Maitre USA has launched FreezeJet, a liquid CO2 jet. The FreezeJet generates a blast of freezing fog in columns of 30 to 40 feet that disappear instantly when switched off, and can be fired at different angles. A 25-foot hose can be supplied as standard or optional, and the design allows the unit to be used with high pressure LCO2, CO2 Dewars or LN2 Dewar tanks (with optional LN2 fitting).

Aluminum stainless steel construction makes the FreezeJet lightweight and easily portable yet robust. Anodized black powder coating ensures good stage camouflage. The FreezeJet can be used to great effect in clubs, theaters, tours and theme parks.
