A compact oil and gas fired steam boiler, delivered complete control system, burner and fittings. Available for operating pressure up to 14 bar.

Opex-Å is a compact steam boiler supplied in low pressure versions, six sizes (150–1000 kW), and high pressure versions, nine sizes (150–2000 kW). The boiler consists of a horizontal pressure vessel insulated with mineral wool. The system is protected by a painted AluZinc sheet steel cover.

Opex-Å is fired with either oil or gas. Combustion takes place in the centre of the combustion chamber. The fully water cooled rear wall returns fumes along the combustion chamber exterior walls, after which the fumes enter the flue gas tubes.

The combustion chamber and the flue gas tubes are accessible through the opening of the burner hatch on the boiler’s short side. The design provides a compact and high efficiency boiler for oil and gas firing. The high efficiency leads to a safe total combustion of the fuel, this is an important factor with respect to environmental considerations.

The boilers are supplied with a factory fitted control system, burner and fittings.
