Every boiler needs a periodic Blow down. Boiler blow down is done to control the TDS levels of water inside the boiler. If the level of total dissolved solids (TDS) in your boiler gets higher than desired limit, you could be facing serious scaling on your boiler tubes and downstream equipment’s,
foaming inside the boiler and water carryover along with the steam. So for better quality steam supply and longer life of the boiler and it’s tube, blow down becomes mandatory.
• Automatic Blow down Control.
• No manual intervention.
• Programmable PLC based controls.
• Available in both the options of Timer and TDS Based System.
It is used for Boiler Blow down as well as cooling tower Blow Down.

Required input connections:

• 230 volts AC / 50 Hz power supply.
• 4 to 6 bar pneumatic supply( whenever pneumatically controlled valve is provided).
• Maximum blow down capacity : 2750 kg/Hr.
• Boiler pressure up to 17.5 kg/cm2.
• Reduced operating costs.
• Reduced maintenance and repair costs.
• Cleaner and more efficient steam.
• Energy Savings


A de-aerator is a device that removes oxygen and other dissolved gases from water, such as feed water for steam-generating boilers. Dissolved oxygen in feed water will cause serious corrosion damage in a boiler by attaching to the walls of metal piping and other equipment and forming oxides (rust). Dissolved carbon dioxide combines with water to form carbonic acid that causes further corrosion. Most deaerators are designed to remove oxygen down to levels of 7 ppb by weight (0.005 cm³/L) or less, as well as essentially eliminating carbon dioxide.

De-Aerator is a dome shaped device [called the mixing unit] fitted to the Feed Water Tank, having three Nozzles for Cold Make up Water, Recovered and recycled hot condensate and Flash Steam. It also has a top vent nozzle with automatic thermostatic vent. The three nozzles result in mixing of the three fluids, consequently heating the water and the Oxygen thus released is vented out from the top.
• Removes Air, Oxygen, and other non-condensable gases.
• Provides effective mixing of BFW with available thermal streams.
• Immersed Perforated Pipe allows uniform heating in Feed water tank.
• Improves efficiency of Boilers by preheating Feed water.
It is used for Boiler Feed water tank. ( Normal atmospheric tanks)
• Recovering condensate and flash steam through a de-aerator head reduces fuel bills substantially by raising the feed water temperature.
