EVOSTA EVA3 80 Circulator for Residential Heating and Air Conditioning with Union Fittings evosta3 80 - 130 - 1"1/2

Benefits:

EVOSTA 3 is a new range of DAB circulators that combines the robustness of mechanical circulators with the advantages of electronic models. The permanent magnet synchronous motor, the frequency converter, and the EEI efficiency rating of ≤ 0.19, combined with IPX5 protection and the integrated drain plug, make the EVOSTA 3 one of the best products in its class in terms of efficiency and reliability. The EVOSTA 3 circulator range is perfectly suited for replacing older three-speed circulators, both due to its compact dimensions and its comprehensive features. The product also simplifies the installer’s work thanks to its single sequential adjustment button and direct access to the motor shaft for potential unblocking.The EVOSTA 3 version is equipped with a display that shows flow rate, head, and power consumption in watts in real time. The EVOSTA 3 version also offers a new automatic air-bleeding feature. To activate this function, press and hold the adjustment button for 3 seconds:

• Optimized power consumption during nighttime operation (ECO-NIGHT function)
• A special connector is provided for quick and easy connection during installation.
• Insulation kit included for a significant reduction in heat dissipation.

Applications:

• Underfloor heating: PC I, PC II, or PP III
• Radiator heating: PP I, PP II, or PP III
• Constant pressure drop systems (boiler primary, solar, heat pump, etc.): VC I, VC II, VC III
• Forced degassing during system startup: VC III
• Sanitary loops: VC I, VC II, VC III
