Available with tank capacities from 500 to 3,250 gallons, the HFE series includes the largest sprayers in the company's SprayStriker equipment family. Intended for municipalities and large contractors, the models offer a high-performance, environmentally friendly solution for winter maintenance, the company says. The sprayers include specialized dual high-flow pumps and flow meters to pump exact application rates on demand with instant responsiveness. Because no bypass system is used, energy requirements are significantly reduced, and the units can be fully powered by the vehicle’s electrical system. As a result, the HFE series is zero emission, and it does not require the truck to be equipped with a central hydraulic system. The standard 12-volt models are capable of spray volumes up to 15 gpm. A 24-volt kit is available for producing spray volumes up to 30 gpm.
