Vertical / Horizontal, Precision Seal, Cement-Lined, Unlined Storage Tanks
PRECISION’s lined Storage Tanks are available in both vertical and horizontal configurations, 24″ to 96″ diameters, and 125 to 5500 gallon capacities. Storage tanks can be used in combination with an electric or gas boiler, or some other independent heating source, for storing and/or heating domestic hot water.
Two linings are available to fit your individual needs. Precision Seal and Cement linings are both NSF-61 compliant.
When properly sized and used in the above mentioned combinations, a water heating system, which provides the right storage capacity and recovery for the time interval needed, can be designed to deliver potable hot water for any job. Because each application varies in total volume, flow rate, duration and timing of peak load period, and temperature needed, a large selection of sizes and capacities is offered by PRECISION. Larger sizes, higher design pressures, and other customizing are also available from PRECISION upon request.
All PRECISION tanks are constructed in strict accordance with the standards of the applicable code of the American Society of Mechanical Engineers (ASME). PRECISION is accredited and certified by ASME under the following construction code stamps: “H” – Heating Boilers; “HLW” – Lined Water Heater; “M” – Miniature Boilers; “S” – Power Boilers; “U” – Unfired Pressure Vessels, for design and fabrication of tanks and vessels of all sizes and types.
The ASME code symbol assures you that PRECISION tanks conform to all the applicable ASME Code requirements. These standards govern the material, design, fabrication, labeling and inspection of pressure vessels. The appropriate ASME Code symbol stamp can be applied only when authorized by an authorized inspector holding a National Board commission after a thorough inspection of each vessel as it is being fabricated. The authorized inspector visually checks quality of materials, dimensional conformity, welds, alignment, and quality of all welds.
A final inspection is performed when the vessels are hydrostatically tested in accordance with the applicable ASME Code of construction to observe for leaks. Manufacturer’s Data Reports, which have been verified and certified by the authorized inspection agency and Precision Boilers LLC, are then sent to the National Board in Columbus, Ohio, for registration.
PRECISION is also approved by Underwriters Laboratory and the American Gas Association for Boilers and Tanks requiring those specific codes.
Insulating and Jacketing
PRECISION’s tanks are not insulated or jacketed as a standard, but are painted with one coat of industrial grade primer prior to shipment. For tanks storing either heated or chilled water, insulation and jacket offer a good return on investment when the original cost of insulation is compared to energy savings from improved efficiency over the life of the tank. The low thermal loss with insulation and jacketing meets the energy efficiency standards of ASHRAE.
