Precision Storage Vessels Pvt Ltd Kanyakumari, Tamil Nadu

Steam boilers must be blow down at regular intervals to resolve some of the suspended and dissolved solids formed during the course production of steam.   These undissolved solids in the boiler water can give rise to foaming and scaling of the boiler tubes and shell. Selection of a blowdown vessel depends on the flow rate and the proportion of flash steam released. Blowdown vessels are manufactured in Carbon steel plates. .

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. Designed and manufactured as per ASME Section VIII DIV I Replaceable bladder design Vertical configuration with ring support Easy to install Factory Recharge Pressure : 0.83 bar Maximum Operating Temperature 115 o C

Indirect Heated Storage calorifiers are one of the easiest method of generating hot water for both domestic and industrial applications. Storage calorifiers are installed in hospitals, hotels, sports centers and general residential buildings. PRECISION Calorifiers can be used in sites where a dedicated plant producing steam for laundry or hot water boiler is available.   Storage Calorifier : Storage calorifers are sized to meet the peak demand period with recovery periods varying from one to four hours.   Advantages Electric power is not required, hence no big investments in Transformer etc. Heating coil duty is high. No frequent shutdown due to short circuit etc. No need of higher inventory electric spares.   ASME Code construction:- All tanks are constructed in accordance with ASME code section IV Stamped and labeled for 125 PSI (8.6 BAR) Standard. Precision also design High Capacity Water Heaters / Calorifiers as per British Standard BS 853:1996 or BS 5500:1997 or in accordance with Art 3.3 of the European Directive EEC/97/23 for pressure equipment. Hot Water Indirect KW Shell Material Configuration Capacity.   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 95ºC to form a glossy lining unaffected by thermal shock from -6ºC to 100ºC. 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.

High Capacity Electric Water Heaters Electric calorifiers are one of the easiest method of generating hot water for both domestic and industrial applications. Electric calorifiers are installed in hospitals, hotels, Sports Centres and General Residential Buildings. Standards ASME Code construction:- All tanks are constructed in accordance with ASME code section IV Stamped and labeled for 125 PSI (8.6 BAR) as Standard. Precision also design electric calorifiers as per British Standard BS 853:1996, BS 5500:1997 or in accordance with Art 3.3 of the European Directive EEC/97/23 for pressure equipment. Advantages Efficiency is maintained throughout the range of load. Even at part load all energy is converted into heat. Space requirements are minimum. Separate boiler fuel storage tanks are not required. Installation is simplified. The calorifier can be installed directly with the power supply. Maintenance is kept to a minimum. Electric calorifiers are clean. Electric calorifiers are extremely quiet. 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 tanks are then forced cured at 95 o C to form a glossy lining unaffected by thermal shock from -6 o C to 80 o C. Precision coat is approved by US department of agriculture and with NSF/61 certification for drinking water. Standard – Shells Steel SA516 Gr-70 Coating FDA approved Precision coat material   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.

Air Receivers are manufactured in quality Carbon steel for storing compressed air with capacities range from 100 litres to 50, 000 litres.   Standards : Precision design and manufacture Air Receivers in accordance with EEC/ 97/23 for pressure equipment or ASME Pressure Vessel code.   Connection : Connection can be of screwed / flanged.   Supports : Supports can be of L type , ring type or Tubular.   Working Pressure  : Air receivers are manufactured to 10.8 bar working pressure as standard ( Pressure available up to 50 bar)   External painting :  All compressed air tanks will be painted with RAL 5015 Blue color.   Optional Accessories : Safety Valve, Pressure Gauge, Auto Drain valve etc.

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 Efficiency is maintained throughout the range of load.Even at part load all energy is converted into heat. Space requirements are minimum. Separate boiler not required. Installation is simplified. The calorifier can be installed with minimum electric load. Maintenance is kept to a minimum. Low nox burners are used. Fuel efficient burners are used. Diesel oil, Natural Gas, LPG and Propane can be used. Can also be used with solar or heat pump system where oil or gas fired system can be considered as a backup. Water heaters are fitted with removable type fire tube heat exchanger. These heat exchangers are made of carbon steel tubes and coated with specially formulated coating material to withstand high temperature. Burner Mono block pressure jet fully automatic oil / gas fired burners are used to heat the water. Depend on recovery, burners can be selected either on / off type or full modulation type.
