Wood pellets

we offer the gentlest deliveries of the hardest, cleanest pellets, to minimise the amount of fines delivered to you.

That doesn’t absolve you of the responsibility of designing your installation to cause as little degradation as possible. But within the constraints of your installation, we will deliver as few fines as possible.
