Pump groups

 Pump stations and manifolds for heating circuits

A pump group is the heart of a solar system, it ensures circulation of antifreeze liquid and enables its flow rate to be controlled. It helps control temperatures and pressure in a system, facilitates connecting an expansion tank and easy filling/refilling the antifreeze liquid. Solar regulators are electronic brains of solar systems. They check and evaluate the temperatures sensed and control the operation of systems with solar collectors.
