Seltron OEP high-efficiency circulator
For heating, cooling and solar systems with an enviable EEI ≤ 0.20.
Seltron OEP 25/60 NEW
The perfect replacement for old, wasteful pumps
The highly energy-efficient Seltron OEP circulator with an enviable EEI ≤ 0.20 is designed for circulating hot water in central heating systems, solar systems and for pumping light liquid media in industry.
In an average household, between 10 and 20% of the electricity consumed is used by standard pumps. With the SELTRON OEP 25/60 high-efficiency circulator with an energy efficiency index ≤ 0.20, electricity consumption can be reduced by up to 80 percent for the same hydraulic power compared to more expensive circulators. As the pump operates in proportional pressure mode, the pump power is adapted to the actual demand of the system.
Return on investment in just 2-3 years
Due to the continuously increasing energy costs and wasteful consumption of unregulated three-stage circulators, replacement with a high-efficiency Seltron OEP circulator is recommended. Depending on the purchase and installation costs, the investment in a Seltron OEP high-efficiency circulator pays for itself in energy savings after 2 to 3 years.
