Grundfos ALPHA SOLAR circulator for a high-efficiency solar water system.

ALPHA SOLAR is a circulating pump designed for solar thermal systems. It features three constant curve modes, and its speed can also be controlled via a low-voltage PWM signal from a solar charge controller.

Reliable and highly efficient
The PWM signal generates an analog signal using a digital source to control pump speed, performance, and to optimize solar capture and ensure minimal energy consumption.

Easy access
A manual release screw can be accessed from the front of the pump.

Remote problem solving
A dry-run warning is available as a PWM feedback signal.

Easy to use
Very easy installation, low noise level and no maintenance.

Fantastic service. I highly recommend this company. What I appreciated was the quick responses, and the technical capability of Federico. As an engineer I get tired of people only interested I selling. Q-Tec was not like this. They took the time to recommend a solution AND. Support it with good solid science.
Highly recommend this company.

This company has really helped me forward with serious technical advice on deciding what replacement pump to order for my pool.
Actually, they actively prevented me from buying the conservative more noisy solution that would also have cost me more on energy consumption in the next years.

De warmtepomp die Q-tech bij ons geïnstalleerd heeft werkt top ! Zij werken alleen met topkwaliteit .
Onze eerste winter - starten bij nachtelijke buitentemperaturen rond het vriespunt. In minimum they are 30-32 degrees. In deze dan ook kunnen handhaven. Heerlijk dat wat beloofd is also effective uitkomt. We kunnen altijd op hen rekenen. The Q-tech team is top!

Really happy with the technical support provided by Federico which correctly identified the issue I was having with my one year old pump.
The accurate support (in English) and over WhatsApp really helped me navigate a stressful 2 day period in not having running water. Thank you!
