Extreme 4 is the premier 4 product locking enclosure, designed for ultimate dilution flexibility and accuracy while providing security and cost control under a lock and key. One dial controls up to four products at up to 8 dilutions. Flow rate for each port is either low flow, 1 gpm (4L / min.) for bottle filling or high flow, 4 gpm (15 L / min.) for bucket filling. A 2.5gpm flow rate for bottle and bucket fill option is ideal for closed loop systems when metering using an insert in bottle. Designed to be a turn-key solution, simply install metering tips required and the system is ready to go.
