Vessel Lining Precision Coat
Precision coat is a polymerized coating which is applied to all internal surfaces of the tank. Tank surfaces are first sandblasted and cleaned to a white metal finish and then precision coat is applied uniformly. The tank is then forced cured at 95C to form a glossy lining unaffected by thermal shock from -6C to 100C. Precision coat is approved by US department of agriculture and with NSF/61 certification for drinking water.
For steam and condensate the battery is a simple 2-pass U-tube battery. Heater batteries are constructed from finned tube. This extended surface reduces the overall size of the battery. Plain tube can be supplied and should be specified at the enquiry or order stage so that provision is made for fitting the larger battery. Plain tube will be recommended when the operating conditions are known to make it advisable.

Principle:-
Precision Tangential air separators removes air from the system through centrifugal action, with a combination of centrifugal force and with reduction of velocity. This makes the air, force water towards the outlet connection, where the separated air moves to the low velocity center. Air is removed from the system through air vent.
Direct Oil / Gas Fired water heaters are the best solution where fuel fired hot water system can be used. Wide range output can be achieved in this water heaters. Fully automatic burners are used for safe operation.
Advantages
Water heaters are fitted with removable type fire tube heat exchanger. These heat exchangers aremade of carbon steel tubes and coated with specially formulated coating material to withstand hightemperature.
Burner
Mono block pressure jet fully automatic oil / gas fired burners are used to heat the water. Depend onrecovery, burners can be selected either on / off type or full modulation type. Burners will be highlyfuel efficient and with low nox capabilities.

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.
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.

Precision coat is approved by US department of agriculture and with NSF/61 certification for drinking water.
Standard – Shells
Heating Element ( Howden UK) : Heaters can be designed to operate in 3-phase, 415 volts, 50 HZ / 60 HZ supply. Precision uses two types of commonly used heating elements namely replaceable element and removable core element.
Replaceable Type : The elements on this type of immersion heater can be changed only after draining contents in the water heater.
Removable Core Type : Failed elements can be changed without draining the calorifier or removing the immersion heater from the shell. This saves time in changing the defective elements and with less down time. By this we can save the heated water without draining it.
Materials : Heating elements are available in copper, incoloy or Incoloy 825 which are suitable for any water conditions.

Operating Conditions :
Chilled Water Buffer Tanks are designed to operate with a minimum water volume, which typically ranges from 22 litre to 38 litres per ton for air conditioning application, for to get better temperature accuracy.
Most of the chiller compressors can only start 3 to 4 times per hour. If the compressor is off and if there is a demand for chilled water the compressor cannot get on immediately. Without chilled water, building will not get the required cooling. To solve this problem chilled water buffer vessels are added in the system. These tanks increase the capacity of the chilled water in the system and stabilize the return.

Expansion Tanks are used in a closed loop heating or chilled water HVSC system to absorb the expanding water and to control the pressure in the system.
Expansion tanks are fitted with a replaceable type heavy duty butyl bladder which absorbs the expanded water thus avoiding direct water contact with the metal tank.
