The optimal position of a SpiroTrap dirt separator
To optimally protect your heating or cooling system, the correct placement of a dirt separator is essential. A dirt separator is preferably installed at the point where the system water enters the heating or cooling unit, usually in the return line.
Why on the return line?
- Here, the water flows back to the (sensitive) system components, such as pumps, heat exchangers and valves.
- Trapping debris at this point will prevent it from causing damage to these crucial parts.
- This not only improves the performance and lifespan of your system, but also reduces the risk of breakdowns and maintenance costs.
With a strategically placed dirt separator from Spirotech, your system stays clean, efficient and protected from contamination, even under the most demanding conditions. This way you ensure a problem-free and durable system.
