Air and Dirt Separators
Precision Air and Dirt Separator are designed to eliminate air and separate debris associated with any hydronic system. In removable type High Velocity air and dirt separator, a removable flanged type end cover is installed so that easy access for coalescing medium and dirt removal. Non removal type high velocity air and dirt separator are also manufactured. Air and dirt separator are designed and manufactured as per ASME section VIII Div 1 and registered with National Board of Boiler and Pressure Vessel inspectors. Material of construction will be carbon steel. Connections are flanged to Class 150, Class 300, PN16 or PN 25. External surface will be coated with red oxide primer and with one coat red enamel paint. Standard working pressure will be 10 bar. Designs up to 20 bar available on request.
Each air and dirt separator to be fixed with air vent. A tap is fitted on top of the removable cover (in removable type) and in body for non removable type to facilitate system fast fill and removal of floating impurities and air trapped within the air separator.
Precision Air and Dirt Separator removes entrained air bubbles and dirt particles in the system. Small Air bubble coalesce and form larger air bubbles which rise to the top of the vessel and vented through the air vent. Dirt particles that are collected at the bottom of the separator can be removed through the blow down valve .In case of coalescing medium to be cleaned then top removable cover to be removed for access. Precision air & dirt separators provide higher efficiency with reduced pressure drops so a smaller pump can be used to achieve maximum efficiency.
PALL Ring Technology
Precision air and dirt separator use proven PALL ring technology. By using Pall Ring technology micro bubbles as small as 18 microns, and dirt particles of 35 microns can be removed. It removes air from place where air vent cannot be installed and also it removes and separates solid particles. Pall Rings are kept in a stainless steel basket which can be removed from the top flange of removable type air and dirt separator. Pall rings are made of Stainless steel 304 material. Air bubbles are separated by the pall ring through coalescene process where dirt particles are caught and drifted to the bottom of the tank, further removed through blowdown valve.
Furnish and install, as shown on plans, a removable / non removable type Air and Dirt separator. The unit shall have flanged inlet and outlet connections to the vessel. A vent connection shall be fitted to the top of the vessel to enable installation of Airvent. Air and Dirt separators shall have all steel body construction designed fabricated and stamped as per ASME Section VIII Div I with a working pressure of 10 bar. Each Air & Dirt Separator to be fitted with a blow off tap to remove the air trapped within the separator. Air and Dirt Separator shall use high surface area pall rings made of stainless steel 304 to separate air and dirt with minimal pressure drop. Removable type Air and Dirt separator shall have removable upper head for removal, inspection and cleaning of the pall ring basket.
