Benefits of SCHWAIGER pellets

✓ Minimal content of short/broken pieces and dust
✓ More efficient combustion
✓ Lower emissions

Get the most out of your heating!

When you burn conventional wood pellets, the inconsistency of the fuel is a major challenge for the control systems. The furnace must constantly respond to disruptive variations and readjust the parameter settings.
With its particularly high percentage of pellets within the ideal length range, the HD technology provides the key prerequisites for achieving maximum possible efficiency in practice.

Lower your heating costs!

The ideal length distribution of SCHWAIGER pellets permits optimal filling of the combustion chamber. With its low percentage of short pellets, the uniform fuel creates a fire bed with a uniform pore distribution.

The advantage: Higher air flow between the individual pellets. Combustion becomes more efficient and consumption drops.

Reduce emissions!

The improved combustion quality also reduces emissions. Independent studies by various research institutes have shown that an excess number of short and broken pellets also has a significant effect on emissions: comparison tests have shown that due to their uniform size, SCHWAIGER pellets have up to 37% less carbon monoxide (CO) in the flue gas*.

SCHWAIGER pellets ensure optimum performance from your pellet heating system and help protect our environment.

Change in pellet piece size in the transport chain

Wood pellets are subject to high stresses during transport. HD pellet technology enables maximum production quality, ensuring the pellets retain optimum properties and piece sizes until they reach the customer’s fuel store.

Superior HD quality compared to conventionally manufactured pellets

Before: With conventional production methods, the proportion of pellets in the ideal length range when unloaded is around 45%.
After: Switching to HD technology increases the proportion of pellets of optimum size for combustion to around 75%.
