DHL_EN_50Hz Electronic Circulators For Heating Systems

PERFORMANCE RANGE

Flow rate up to 3.5 m3/h (0.97 l/s)
Head up to 6 m

INSTALLATION AND USE

Energy-efficient, class A electronic circulators significantly reduce electricity use by up to 85% compared to traditional models with similar performance, making them an ideal choice for home and residential heating systems. These circulators feature advanced control electronics that allow for customizable functionality to meet the specific needs of various systems. Users can easily adjust and select the desired operating program directly from the electrical panel’s controller, enhancing system efficiency and comfort by minimizing energy consumption and reducing water flow noise in pipes, valves, and radiators. For optimal perfor-mance, installation should be in well- ventilated, enclosed spaces or areas protected from the elements.

APPLICATION LIMITS

Liquid temperature between +2 °C and +95 °C
Ambient temperature between 0 °C and +40 °C
Maximum working pressure = 6 bar.
Minimum suction pressure:
- 0.3 bar to 50 °C
- 1.0 bar to 95 °C
Maximum relative humidity ≤ 95%.
Sound pressure level < 43 db(A)
Glycol maximum 30%
Continuous running duty S1

COMPONENTS

OPERATING MODE

The electrical panel enables users to select the optimal working curve for the circulator through three distinct programs. A bright LED indicator displays the circulator’s operating status, with variations in illumination providing clear, at-a-glance information.

PROPORTIONAL PROGRAM

GREEN LED
This setting proportionally adjusts the pressure (head) based on the system’s heat demand and desired flow rate

CONSTANT PROGRAM

ORANGE LED
This setting maintains a constant pressure level (head) according on the system’s heat demand and desired flow rate.

CUSTOMISED PROGRAM

LED BLU
Allows the pump’s speed to be set to a constant level, adjustable through a selector that can be positioned between the MIN and MAX settings to fine-tune performance.

An LED indicator on the electrical panel alerts users to the potential presence of air in the system. Should this occur, the circulator’s onboard electronics automatically engage a mo-tor unlocking feature to resolve the issue.
