Company's entryway foamer generates more foam with reduced amounts of chemicals using a high CV, or flow coefficient value, to create thicker, longer-lasting foam. A programmable logic controller with a real-time clock and adjustable dispense and dwell time settings allows users to foam on schedule for a pre-determined amount of time. The real time clock controls the operating hours so chemicals are not wasted, even if the unit is not turned off at the end of the day. These systems help keep E. coli, salmonella, listeria and other pathogens from migrating at processing plants, and should be placed in all critical entries. These fully automatic systems replenish heavy antibacterial foam as needed throughout the shift. It can be set up as a stand-alone unit or linked in multiple units to a central chemical source.
