The OPX thermal oil generator has 3 pass configurations with single pass combustion chamber and flue gas outlet in the rear. Is designed for low thermal loads and high oil speeds in order to eliminate any risk of cracking, namely the process of oil thermal decomposition when the oil is subjected to overheating.

In addition, the very low thermal capacity, due to reduced use of refractory cements, involves a high degree of reliability against the risk of overheating even in cases of oil circulation arrest. 

• Thermal oil heat generator, horizontal axis coil spirally wound
• Fe 35 UNI 663/68 carbon steel, “MANNESMANN” quality S. S. tube coils built curved with multiple tangent spirals, various combustion gas revolutions being separated.
• Carbon steel boiler support able to ensure whole group support; a service platform is provided laterally along with the diathermic fluid circulation group
• Bolted front door, easily opened for inspection and cleaning, equipped with cone burner and combustion control light.
• External high density, mineral wool thermal insulation, with aluminium finish sheet mounted on a rectangular frame
• Fumes connection to flange exhaust, housed in the upper fumes chamber, bolted to the boiler and easily removable for cleaning operations.
