Technical data
Every value, against the standard that governs it.
Measured on the current production run. The right-hand column is the ENplus A1 requirement, not our marketing claim.
| Parameter | Unit | Silvapel | ENplus A1 |
|---|---|---|---|
| Moisture | % | 6.8 | ≤ 10 |
| Ash content | % | 0.42 | ≤ 0.7 |
| Mechanical durability | % | 98.6 | ≥ 98.0 |
| Fines below 3.15 mm | % | 0.4 | ≤ 1.0 |
| Net calorific value | MJ/kg | 17.6 | ≥ 16.5 |
| Bulk density | kg/m³ | 680 | 600–750 |
| Diameter | mm | 6 / 8 | 6 ± 1 / 8 ± 1 |
| Length | mm | 3.15–40 | 3.15–40 |
| Chlorine | % | 0.01 | ≤ 0.02 |
| Sulphur | % | 0.02 | ≤ 0.04 |
| Nitrogen | % | 0.12 | ≤ 0.3 |
| Ash melting temperature | °C | ≥ 1250 | ≥ 1200 |
Values are from the most recent batch analysis. A signed analysis accompanies every shipment, so incoming inspection has a document to check against rather than a claim to trust.

Where we sit in the window
The margin matters more than the pass.
Meeting ENplus A1 is binary. How much room you leave inside the window is what decides whether a batch still passes after a long sea transit and a humid warehouse.
- Moisture0%0limit max 10 % · ENplus A1 M1012.5
Room left before the ceiling absorbs transit humidity.
- Ash content0%0limit max 0.7 % · ENplus A1 A0.70.875
Lower ash means longer intervals between burner cleanings.
- Mechanical durability0%95limit min 98 % · ENplus A1 DU98.0100
Axis narrowed to 95–100; durability differences live in the last two points.
- Net calorific value0MJ/kg15limit min 16.5 MJ/kg · ENplus A119
Axis narrowed to 15–19, the practical range for wood pellets.
Meters show the measured value against the ENplus A1 limit. Where the axis is narrowed rather than starting at zero, both endpoints are printed on the scale.

Quality and compliance
The document set a European distributor expects.
Bagged pellets are bought on ENplus and DINplus. The industrial schemes (SBP, PEFC chain-of-custody) belong to bulk power-station supply and we do not claim them here.
