Hanna’s Global Mini-Tunnel™ can fit in most standard rollover bays and can wash 35 to 60 cars per hour. Utilizing the most productive combination of Hanna brush components, the Global system is able to thoroughly wash the top horizontal and vertical surface of the vehicle. Hanna’s mini-tunnel is more profitable than a standard in-bay automatic because of its high volume capabilities and relatively low cost. A common complaint from in-bay operators is that they just don’t wash cars fast enough and long lines encourage drive-offs and missed opportunities. Hanna’s mini-tunnel is twice as fast as most in-bay automatics, which means it can double your wash volume while reducing drive-offs — turning your rollover bay into a true profit center.
