The LTC300 series filling unit is designed to ensure and maintain a high return water temperature to the boiler. This parameter contributes to extending the boiler's lifespan, reduces tar formation, and increases boiler efficiency. The unit is used for filling accumulation tanks and protects the boiler from excessively low return water temperatures. It features an integrated auto-circulation function, allowing the unit to operate even during power or pump failures.

The unit is already equipped with a highly efficient and economical pump that complies with the EU directive on energy-related products (ErP).
