Pulp and paper mills are among the most steam-intensive industrial operations, the paper machine dryer section alone can use hundreds of steam traps, and the recovery boiler and evaporators require high-performance valves and control equipment. Indonesia is one of the world's largest pulp and paper producers, with modern mills requiring constant steam equipment supply.
In Indonesia, we supply equipment to major pulp and paper groups including Asia Pulp & Paper (APP/Sinar Mas, OKI mill, Lontar Papyrus, Indah Kiat, Pindo Deli), APRIL Group (RAPP mill in Riau), Fajar Paper, and Tjiwi Kimia. These world-scale mills in Sumatra, Riau, and Java operate 24/7 and require reliable, rapid spare parts supply.
In East Africa, we serve paper manufacturing in Kenya (Pan Paper Mills/Rai Paper, Chandaria Industries), Tanzania (Mufindi Paper Mills), and Ethiopia. While smaller than Indonesian operations, these mills share the same fundamental steam equipment requirements.
| Product Category | What We Supply |
|---|---|
| Steam Traps | Dryer cylinder traps (high-capacity FT and IB types), thermodynamic traps for steam headers, thermostatic traps for felt dryer and ventilation coils. Trap monitoring for the hundreds of traps on each paper machine. |
| Control Valves | Pressure control valves for dryer section steam, temperature control for digesters and evaporators, level control for condensate systems. |
| Boiler Spares | Recovery boiler tubes and components, bark/biomass boiler spares, power boiler parts. Soot blower elements and safety valves. |
| Condensate System Spares | Flash vessel internals, condensate pumps, deaerator components, critical for high condensate loads from paper machine dryer sections. |
| Valves | Gate, globe, and ball valves for steam distribution. Pressure reducing valves for dryer section pressure control. |
| Strainers | Y-strainers before every steam trap on the dryer section. Basket strainers for condensate and feedwater systems. |
Indonesian pulp and paper mills are world-scale operations running 24/7, unplanned downtime on a paper machine can cost $50,000-$100,000+ per day. Steam trap management is particularly critical: a modern paper machine has 200-500 steam traps on the dryer section alone, and failed traps cause uneven drying, sheet breaks, and energy waste. AQ Process Systems provides bulk trap supply, monitoring equipment, and scheduled replacement programmes to maintain dryer section efficiency.
Yes. We supply high-capacity float & thermostatic (FT) and inverted bucket (IB) traps specifically for paper machine dryer cylinders. Correct trap selection and sizing is critical for dryer efficiency, we advise on trap type and size based on your machine speed, dryer can size, and steam pressure.
Yes. We supply to major mill sites in Sumatra (OKI, Lontar, RAPP) and Java (Pindo Deli, Tjiwi Kimia). We understand the procurement requirements of large mill groups and provide competitive bulk pricing with scheduled delivery to align with maintenance planning.
Yes. We supply trap monitoring equipment and can coordinate survey services, testing all installed traps, identifying failures, calculating steam losses, and recommending replacements. For paper mill dryer sections with hundreds of traps, systematic monitoring is essential for energy management.
A modern paper machine has 200-500 traps on the dryer section. Annual failure rates of 10-20% mean 20-100 replacement traps per machine per year. We supply bulk trap packages at competitive pricing, with the correct mix of sizes and types for your specific machines.
Yes. We supply tubes, tube panels, smelt spout components, soot blower elements, and other recovery boiler parts. Recovery boilers handle highly corrosive black liquor, materials must be correctly specified for the operating environment. We source from manufacturers with proven experience in recovery boiler service.
