Are you up to date on Taco’s newest addition? Taco Comfort Solutions has recently released two new models for their PAX Series Potable Water Expansion Tanks, the PAX25 and the PAX10. The PAX Series Family now has a capacity range of 2.6-132 gallons (10-500 liters), which makes it more flexible than ever for your application requirements.
But, what makes these so different from other expansion tanks? The PAX Series Expansion Tanks use a heavy duty partial acceptance rubber bladder design for potable water systems, and they still provide permanent separation of air and water.
Here are 6 things you should know about the PAX Series Potable Water Expansion Tanks:
- The PAX Series consists of 13 different models, varying in size and capacity. These expansion tanks can range from 2.6-132 gallons of capacity and range in height from 12-85 inches and diameter from 12-24 inches. The possibilities are nearly endless with these tanks so that the application requirements can be met.
- It is designed, constructed and tested to ASME Section Vlll, Div. 1 requirements. “This Division of Section VIII provides requirements applicable to the design, fabrication, inspection, testing, and certification of pressure vessels operating at either internal or external pressures exceeding 15 psig.” (asme.org) Fulfilling these requirements ensures these tanks are of highest quality and performance.
- All fabrication is done in house. By Taco doing this, it ensures a high level of quality.
- Taco makes choosing the right equipment easy with their computerized product selection. This will allow that the right expansion tank is the correct fit for the application requirements, creating an overall easier process.
- PAX bladder tanks use a field replaceable bladder to permanently separate the air and water. This allows for the tank to be precharged on the air side to the minimum operating or fill pressure, eliminating many gallons of water that is typically used to compress atmospheric pressure.
- In a PAX bladder tank, the partial acceptance bladder is not attached to the tank wall like a diaphragm tank. It is actually in the bottom of the expansion tank utilizing an internal assembly connecting to the stainless steel system connection located on the top of the tank.
