When steam is essential to keep operations running, there is no room for delays, uncertainty or inefficiency. Whether facing an unexpected boiler failure, a planned shutdown or a sudden increase in demand, the challenge is the same: restore reliable steam quickly, without compromising on performance, safety or sustainability.
The 4,6Ti steam boiler has been developed to answer exactly that challenge.
This compact yet powerful unit strengthens the rental steam offering with a solution designed for rapid response and real industrial conditions. It delivers the performance expected from a permanent installation, while remaining flexible, mobile and easy to integrate when time is critical.
Fast to site, fast to steam
Speed is one of the deciding factors in emergency steam situations. Using Atlas Copco Specialty Rental’s ‘plug-and-steam’ approach, the unit can be mobilized quickly and connected with minimal site preparation. Its compact footprint means it can be transported using standard logistics and installed either as a mobile unit or fully integrated into an existing system.
The result? A faster turnaround reduced downtime and a quicker return to normal operations.
With its integrated smoke economizer, the 4,6Ti recovers heat from exhaust gases to preheat feedwater. This combined with its three-pass boiler design, allowing the unit to reach operating efficiencies of up to 95%, while maintaining consistent steam quality at a 16 barg design pressure.
Intelligent control for stable, reliable performance
The 4,6Ti is designed to operate smoothly under varying load conditions. Its low-NOx dual-fuel burner allows operation on natural gas or oil, providing flexibility in fuel choice without sacrificing environmental performance.
Advanced control systems are continuously collecting and analyzing operational data to support reliable operation and early identification of potential issues. The Variable Speed Drive (VSD) burner adjusts fuel and air supply to match real demand, while O₂ regulation monitors flue-gas oxygen levels and fine-tunes fan speed.
Built to run with minimal intervention
In many situations, boiler supervision can be limited. The 4,6Ti is engineered with this reality in mind. Automated water quality management, blowdown control and safety systems allow the boiler to operate for up to 72 hours without supervision, while remote monitoring provides visibility and reassurance.
Steam continuity, without compromise
The 4,6Ti expands the modular steam range alongside larger units, offering a smaller yet highly capable alternative for applications where space, speed and flexibility matter. Its design makes it suitable for a wide range of industries and emergency scenarios, without introducing unnecessary complexity.
The 4,6Ti steam boiler is more than a rental unit. It is a purpose-built solution for situations where steam must be restored fast, operate efficiently and remain dependable from the moment it is commissioned. By combining rapid deployment, high efficiency and intelligent automation in a compact design, the 4,6Ti helps safeguard production, control costs and reduce risk. Exactly what’s needed when steam is critical and time is limited.
