The PRESS T/N series of burners offers a powerful and versatile solution for commercial and industrial installations. With a firing range that spans from 800 to 5130 kW, these burners are capable of meeting the heating requirements of a wide range of applications. Designed in three versions, the PRESS T/N burners are suitable for burning oils with varying viscosities, ranging from 7 to 60 °E @ 50°C. This flexibility allows them to adapt to different fuel types and ensures efficient combustion across various operating conditions. Operating in a three-stage mode, the burners are well-suited for installations with variable but predictable heating requirements. A servomotor automatically adjusts the air damper opening, ensuring the optimal fuel consumption at each stage. This precise control mechanism guarantees reliable and efficient performance. Each model of the PRESS T/N series is available in two different combustion head lengths: short or long head. This feature provides flexibility to select the appropriate head length based on the specific application requirements. It allows for optimized combustion performance and ensures compatibility with different heating systems. To maintain the oil at the correct atomizing temperature during maximum output, an electric preheater is integrated into the burners. This preheater ensures consistent atomization and combustion efficiency, even under demanding operating conditions. Special heater kits are also available separately for burning high viscosity oils, expanding the range of fuel options. The Riello designed slide bar system simplifies maintenance procedures for the burners. This system allows easy access to all essential components of the combustion head, streamlining routine maintenance and servicing operations.
