Construction Features
The R Series burners are constructed from cast iron, allowing them to withstand high temperatures. They feature aluminum venturies, brass nozzles with aluminum primary air regulators, and a manually operated ¼-turn handle. These burners are suitable for natural gas or LPG applications, with diameters ranging from 120 mm to 500 mm and energy ratings between 5,000 kcal/h and 125,000 kcal/h in atmospheric operation. Custom-built options can include gas-air mixers for a maximum rating of 400,000 Kcal/h.

General Features Chart
The document provides a detailed chart of various models (R-40, R-48, R-63, R-100, R-130, R-199, R-130/73, R-130/258) with their respective capacities for natural gas and LPG, gas intake sizes, and body diameters. For example, the R-40 model has a natural gas capacity of 5,000 kcal/h and an LPG capacity of 4,000 kcal/h, with a gas intake of 1/2" and a body diameter of 120 mm.

Atmospheric Systems
Models such as R-100 GA, R-130 GA, R-199 GA, R-130-73 GA, and R-130-258 GA are listed with capacities for both natural gas and LPG, gas intake sizes, and body diameters. The R-130-258 GA model, for instance, has a capacity of 400,000 kcal/h with a gas intake of 1 1/2" and a body diameter of 500 mm.

Safety Systems
The R Line industrial burners incorporate various safety systems, including thermocouple safety valves, electrically-operated valves for temperature control, and electronic operation with ionization flame control, complying with ENARGAS standards.

Applications
These burners are suitable for a wide range of applications, including liquid heating containers, reactors, food industry processes, boilers, hot water tanks, low melting-point metal kilns, hearths, salamander heaters, ovens, drying ovens, heat generators, industrial stoves, and various processes. The ratings are based on gas pressures of 20 mBar for natural gas and 28 mBar for LPG.
