Nautis MCU Motor Controller
The Nautis™ MCU is a motor control unit that optimizes every aspect of pool pump ownership. Nautis MCU turns an ordinary variable speed pump, into something truly unique! Offering provides adaptive flow control, heater control, and an array of other advanced features and functionality.
complete optimization of your pool pump
The Nautis™ MCU from H2flow Controls brings the revolutionary adaptive flow technology of the Nautis™ VSF to virtually any variable speed pool pump. Designed as a standalone motor control unit, Nautis MCU transforms conventional variable speed pumps from speed-based operation to intelligent flow-based operation, allowing pool owners and operators to achieve precise, constant circulation without replacing their existing pump. Built around H2flow’s proven Eco-Flow® technology, Nautis MCU continuously monitors actual system flow and automatically adjusts pump speed to maintain the desired flow rate as conditions change.
Unlike traditional variable speed pumps that rely on fixed RPM settings, Nautis MCU adapts to real-world conditions such as filter loading, changing system resistance, or valve adjustments. The result is optimized turnover, improved water quality, reduced chemical consumption, lower energy costs, and extended equipment life. By delivering the same intelligent, adaptive flow functionality found in the Nautis VSF, Nautis MCU provides a simple and cost-effective upgrade path for existing variable speed pump installations.
Key Benefits
Maximized Energy Saving Potential
Optimizing pump speed and heater usage based on the flow rate typically results in significant energy savings.
Reduced Equipment Wear
Running the motor at the required speed - and not unnecessarily exceeding it - will result in prolonged equipment life.
Optimal Chemical Usage
If the speed is set too high, unnecessary chemical usage occurs. With Nautis™ MCU, the speed is optimized, meaning chemical usage is, too.
Adapts to Changing Conditions
In an effort to maintain constant flow, Nautis™ MCU will sense - and adapt to - dirty filters and other conditions that reduce the flow rate.
Compatible Pumps:
✓ All pumps that use US Motors (Nidec) Neptune Variable Speed motors
✓ Speck USA pumps
✓ Waterway Pumps ✓ Carvin Pumps
