    It can be used in marine boilers operating at pressures up to 40 bar. Catalysed sodium sulphite is used in most cases, as the reaction time with oxygen is extremely fast even at ambient temperature. In marine practice, particularly for low pressure shell type boilers, it is usual to add the catalysed sodium direct to the boiler and not Learn More
