CIRK-PUMP VVC GRUNDFOS MAGNA3 25-100 N

MAGNA3 25 - 100 is an intelligent and energy-efficient circulator pump for domestic hot water systems. Unique AutoAdapt and FlowLimit functions make operation easy and save energy. Voltage 230 V and immersion depth 180 mm. Grundfos MAGNA3 series intelligent and energy-efficient circulator pumps are suitable for heating systems, air conditioning, cooling, domestic hot water recirculation, and ground and solar thermal systems. MAGNA3 EEI values comfortably meet the strict EuP 2015 regulation requirements. MAGNA3 25 - 100 N features - infinitely variable speed control without connectors or backflow preventers - flow can be set, read, and limited directly from the display or via Grundfos GO for optimized operation - low operating costs and the best energy efficiency on the market - alarm and operating status information as standard for building automation interface, relay outputs as standard - 0 - 10 V control as standard, enabling zero-flow shutdown to be activated - external sensor enables differential temperature control and thermal energy measurement Functions - AutoAdapt: automatically adapts the pump to system requirements by creating the optimal relative pressure curve. - FlowAdapt and FlowLimit: enable setting a maximum flow limit on the MAGNA3 pump. The pump continuously monitors the desired flow, reducing system imbalance risk and the need for balancing valves. This improves the overall energy efficiency of the system.
