Smart Fuel Management
Two-Pipe Efficiency with One-Pipe Simplicity
Tigerloop® Auto 2 combines the benefits of a two-pipe system for the fuel pump with the environmental and operational advantages of a one-pipe system for the tank. Only the fuel consumed by the burner is drawn from the tank, reducing dirt particle transport and promoting cleaner combustion.
Leak Prevention and System Safety
By eliminating the pressurized return line to the tank, Tigerloop® removes the risk of leakage, enhancing system safety and reliability.
Self-De-Aerating Functionality
Fuel drawn from the tank often releases air bubbles—especially with biodiesel, which varies in viscosity under cold conditions. These bubbles can cause disruptions, soot buildup, and premature wear. Tigerloop® Auto 2 acts as a self-de-aerating day tank, eliminating these issues.
Built-In Fuel Heating
The friction generated by the pump heats the fuel circulating between the Tigerloop® and the fuel pump, improving flow and combustion efficiency—a major advantage in cold climates.
