STI’s Tri-Drive Trailers were engineered with municipalities, large facilities, property management companies and contractors in mind. The TV.712 has a 6’8″ overall height to provide access to almost any parking facility and is no larger than a full-sized SUV. At a relatively light 5,000 pounds (dry), it can be safely towed by a 250/2500 or larger truck.

Best-in-class Kohler Command-Pro V-Twin Fuel Injected engines have a 3-year warranty and Kohler has thousands of authorized service centers across the US. Fuel capacities of 50 gallons each of diesel and gasoline provide days worth of fuel, not hours. Three AGM Gel Marine Batteries connected to a 3500 watt DC/AC Inverter eliminates the need for a gas powered generator.

Dual Annovi Reverberi 3600 psi @ 8 gpm Triplex Pumps provide enough water on target to put two 30″ Mosmatic Recovering Surface cleaners and two guns to work. Combined with a custom diesel burner providing up to 200°F degree water, up to 60,000 sq. ft. can be effectively cleaned in one shift.

A 27HP Kohler directly drives a Tri-Lobe Blower to generate up to 700 cfm of vacuum to recover the used wash water and a 20-stage 400 gallon wash water filtration system, with “Active Bypass” keep you compliant will all recovery requirements of the EPA, state and local regulators.
