BECSys7 Equipment Room Control
Description
BECSys7 equipment-room controls provide continuous
monitoring and control of sanitizers, oxidizers, pH,
conductivity, turbidity, enzyme feed, system flow rate, system
pressures, chemical inventory levels, and surge tank and
backwash holding tank levels. The BECSys7 can provide
automatic filter backwash for up to 16 filters.
BECSys7
Equipment Room Controller
Patent-pending VFD control technology assures optimal and
efficient circulation pump operation.
All inputs and system events are recorded in on-board data
logs, accessible with BECSys for Windows Vista-compatible
PC software.
Every controller comes with factory-trained start-up and
support provided by local distribution. The BECSys7 controller
comes with a manufacturer’s 5-year electronics and 2-year
pH, ORP & temperature sensors and 1-year optional sensors
warranty.
