Do you know that there is something called a DE tank in your boiler? Heating and cooling cycles require provision for expansion and contraction of heating oil, which also needs to be shielded from atmospheric oxidation and de-gradation. The vapours arising from hot oil surface being hazardous need to be let out to atmosphere in a safe manner. All this is achieved in a unique DE tank comprising of three functional sections - de-aeration section to remove trapped vapours from hot oil, a buffer zone to isolate hot circulating oil from the stored tank oil and the main tank body to accommodate expansion/contraction of thermal oil in circulation.This tank also carries nozzles for topping up of thermal oil over an extended operating period, over-flow, drain nozzles & level indicator. Hot oil piping is thus simplified to a great extent by using this combination tank. Similarly, there are expansion tanks for hot water generators. In pressurized hot water heating systems, circulating hot water is maintained under hydraulic pressure higher than saturation point to avoid steam formation. Further, provision has to be made to account for expansion and contraction of water mass under circulation. Both these are achieved through the use of a pressurized expansion tank, fitted with necessary valves and instruments. Expansion tank is pressurized with the help of compressed air or nitrogen al pressure corresponding to hot water outlet temperature from boiler. These tanks are made in various sizes and are available as standard accessories for hot water generators.

You may additionally get water softeners and filters for water treatment. There are some boiler manufacturers that also design water softeners for a wide range of commercial and industrial applications. The main unit is made from corrosion resistant fiberglass and is skid mounted. It is supplied preassembled with water pump and starter. A wide variety of models in standard configurations as well as custom built units to suit customers specific applications are available. Water softeners are used in a wide variety of applications like milk dairies, food processing units, chemical processing factories, pharmaceutical units, hotels, hospitals, schools, factories, laundries, boiler feed water, apartments and resorts.Using the correct softener increases the boiler efficiency and life. Costly boiler repairs can be greatly reduced. And then there are activated carbon filters that are designed and manufactured with dual filtering media like sand and activated carbon. These filters can be used as initial unit for industrial water treatment. It is also used as pre-treatment and tertiary treatment of waste water.
