Get priceIn low pressure boilers, water purification and pre-treatment would usually involve ion-exchange. However, with high pressure boilers where the pressures required in the boiler are significantly higher, the quality of the boiler feed water needs to be much better, and this can be achieved using a reverse osmosis (RO) pre-treatment process.
Get priceBased on the pressure rating, boilers can be classified as high pressure, medium pressure and low pressure boilers. Generally, boilers operating above 22 Kg/cm 2 are considered as high pressure boilers. Those operating below 10 kg/cm 2 are considered as low pressure boilers.
