Working Principle
Hot pellets enter at the top through a rotary airlock and build a bed in the cooling bin. Ambient air is drawn up through the bed against the product flow, so the coolest air meets the coolest pellets. A slide-valve discharger at the bottom releases cooled pellets steadily.
Key features
- Counterflow cooling principle
- Full and uniform pellet cooling
- Pellets ≤ room temperature +3–5 °C
- Cooling time not less than 10–15 min
- Smoothly running slide-valve discharge
- Rotary airlock at the inlet
Technical Data

| Model | Cooling volume (m³) | Capacity (t/h) | Power (kW) | Airlock power (kW) |
|---|---|---|---|---|
| SKLN2.5 (15×15) | 2.5 | 6 | 1.5 | 0.75 |
| SKLN4 (20×20) | 4 | 10 | 2.2 | 1.1 |
| SKLN6 (22×22) | 6 | 15 | 2.2 | 1.1 |
| SKLN8 (24×24) | 8 | 20 | 2.2 | 1.5 |
| SKLN12 (28×28) | 12 | 30 | 1.5 + 2.2 | 1.5 |
All models: cooling time not less than 10–15 minutes, product temperature not higher than ambient +3–5 °C, air absorbing volume 34 m³/min·t.

Questions
Straight answers to the questions our engineers hear most about the SKLN Counterflow Cooler.

Talk directly with our engineering team for a tailored consultation.
What is the price of a pellet cooler in Pakistan?
It depends on the model (SKLN2.5 to SKLN12) and the fan, cyclone and airlock package. Tell us your pellet mill output and we will quote a matching cooler.
Why do pellets need cooling?
Pellets leave the pellet mill hot and moist. Cooling hardens them and lowers their moisture, which prevents cracking and mould during storage.
How do I size the cooler?
Match it to your pellet mill: SKLN4 for about 10 t/h, SKLN8 for 20 t/h and SKLN12 for 30 t/h.
