Alpha Solar

Overview

Overview

Electronically controlled circulator pumps for all kinds of thermal solar systems with either variable or constant flow rate.

The new ALPHA SOLAR is designed to be integrated in all kinds of thermal solar systems with either variable (matched-flow) or constant flow rate. High-efficiency ECM (Electronically Commutated Motor) pumps, such as ALPHA SOLAR, must not be speed-controlled by an external speed controller varying or pulsing the supply voltage.

The speed can be controlled by a low-voltage PWM (Pulse Width Modulation) signal from a solar controller to optimize the solar harvesting and temperature of the system. As a result, the power consumption of the pump will be reduced considerably. If no PWM signal is available, ALPHA SOLAR can be set to constant speed, only switched on and off by the controller.

  • System pressure : Maximum 1.0 MPa (10 bar)
  • Minimum inlet pressure : Minimum inlet pressure 0.05 MPa (0.50 bar) at 95 °C liquid
    temperature
  • Maximum liquid temperature : 2-110 °C at 70 °C ambient temperature/ 2-130 °C at 60 °C ambient temperature
  • Enclosure class : IPX4D
  • Motor protection : No external protection needed
  • Approval and marking : VDE, CE
  • Water/propylene glycol mixture: Maximum water/propylene glycol mixture is 50 %.

*Note: The water/propylene glycol mixture reduces the performance due to higher viscosity.

Applications

  • Solar thermal installations for domestic heating application
  • Domestic chilled water application
  • Domestic hot water recirculation

NOTE: Depending on local regulations, this product may not be approved for domestic hot water recirculation and a pump with complete stainless steel (ALPHA 3 N) maybe required.

Benefits

  • Constant speed
  • PWM C profile. The PWM signal is a method for generating an analog signal using a digital source
  • Low EEI (Energy Efficiency Index)  ≤ 0.2
  • Maintenance-free
  • Low noise level
  • Very simple installation
