Short answer
The SR40 V3 carries N+1 redundancy on its primary circulation pumps. The integrated PLC monitors pressure, flow and fluid temperature continuously — and if a primary pump fails, the standby pump engages automatically while operators are alerted, preventing hardware throttling or emergency thermal shutdown.
- N+1 redundancy on primary pumps
- PLC watches pressure, flow and temperature
- Standby pump engages automatically
- Operators alerted on every failover
What happens when a primary pump fails
- Deviation is detected — the PLC flags pressure or flow outside specification.
- Standby engages — the backup pump starts automatically — no manual intervention needed.
- Operators are alerted — the event is raised to the monitoring platform for follow-up service.
- Load keeps running — cooling continues without throttling hardware or triggering a thermal shutdown.
Why the loop is designed this way
- Continuity is the design target. Maintenance downtime directly impacts profitability, so critical paths carry redundancy.
- Service without shutdown. A failed pump can be serviced while the standby keeps the loop running.
- Monitoring is continuous. The PLC supervises system pressure, flow rates and fluid temperatures around the clock.
