Electrical Components
• Main circuit breaker disconnect provides true Single Point
Power Connection for cooling tower/fluid cooler controls.
The electrical contractor connects a single power source
and the SPPC panel provides power feeds, controls and
voltages for tower controls. Typically each cell of a tower
would require one SPPC panel.
• User terminal points for connecting field devices —
solenoid, water level probes and alarm devices
• Pilot lights
• Status contacts for BMS interface
• User terminal strip
• Wiring diagram secured inside the panel door
• Built to UL and CUL standards
OPTION S
• SPPC panels are customized per project to accommodate
cooling tower/fluid cooler control options:
– Feeder breaker for remote VFD
– Fan motor sequencer for multiple single and two speed motors
– Starter for the fan motors — 1 or 2 speed
– Integrated water level controls — make-up, alarm and cutouts
– Integrated basin heater controls
– Fluid cooler control — starters, pumps, dampers, heat trace
– Other specials as required
• Water level advanced controls:
– Transfer switch between multiple probe sets for dry
servicing a tower fan cell
• Basin heater advanced solid state temperature controls:
– Two-line LED display of set-point and actual water temperatures
– User adjustable temperature settings
– Alarm output-relay activates when approaching a freezing
temperature
– 4-20mA output signal to BMS for water temperature indication
– Industrial PT100 temperature RTD
– Current pickup relays assuring element is actually heating
