The Colt 4 Turbo has a no-mess smoke chemical canister system and high mass heat exchanger for â off powerâ use. The Turbo version incorporates a large mass, precision machined heat exchanger block, and 2 x 1100w Firerod cartridge heaters switched via a solid stse relay. The result would be almost twice the smoke output of the standard Colt 4 as well as the ability to make smoke on â Off Powerâ mode for longer time â because it has a greater amount of retained energy within the heat exchanger. The â Off Powerâ mode allowed the operator to carry a generator from room to room making smoke as required without trailing an electrical lead. With its comprehensive enhanced performance, the Colt 4 Turbo is able to perform smoke logging in larger volumes, more quickly, and to denser smoke concentrations than any other similar system. However, the smoke output is totally adjustable to your liking, so, if required, smoke output can be reduced from a powerful plume to a small wisp. The unit uses the standard, one piece aluminium Colt 4 smoke can to produce an extremely persistent smoke. The can comprises of both the smoke chemical and the INERT propellant gas which are required to make the smoke. The canister automatically re-seal after use, so they can be used time and time again until exhausted. The Colt 4 smokes small particle size results in much lower chemical concentrations to achieve and maintain specific smoke concentrations than conventional smoke systems. The Colt 4 Turbo smoke machine is an ideal tool especially for fire training and special effects purposes.
