Istobal’s HW’Intrawash Cleaning and Sanitizing System for refrigerated and dry van trailers and shipping containers is designed to help facilitate safe and controlled sanitization while maximizing efficiency. The system is designed to decrease cleaning time and water and chemical usage by using a high-pressure pumping system to deliver 33 gpm at 1,100 psi and a chemical dosing system with multiple programs that can be adjusted for each fleet’s concentration, quantity and reaction time requirements. It is engineered for easy installation and use to clean and sanitize a 53-foot trailer in about six minutes. The automatic equipment consists of a fixed base, with an elevator platform or with lateral movement as an option, and can be installed indoors in a wash bay or outdoors on a loading dock. A set of stainless-steel guides are moved by a conveyor motor controlled by a frequency converter that regulates speeds on each program pass. An optional stainless-steel hopper collects waste from the interior wash process and incorporates a self-rinsing arch that helps keep the unit itself clean.
