American Wheatley products

The American Wheatley HVAD High Velocity and STAD Standard Velocity Coalescing Air & Dirt Separator is intended for use on commercial HVAC, institutional, and industrial applications to remove entrained air and particulate from system water. We accomplish this with the use of a high-performance saddle ring coalescing assembly internal to the separator. The American Wheatley HVAD & STAD series coalescing type air & dirt separator is capable of removing 99.6% free air and 99% of the measurable entrained and dissolved air with continuous circulation. Solids to 20 microns can be eliminated within 100 passes of continuous circulation.

Our In-line Air Separators series offer a lower-cost alternative for air separation in hydronic heating and cooling systems. The IAS/IASS series become a point of lower system velocity by changing the direction of flow through the device. This lower velocity, along with the change in direction, allows air molecules to separate from water, rise within the inline air separator, and be discharged through the vent opening at the top of the vessel either to the atmosphere or to an expansion tank. We also offer a MG-Magnetic Option for air separators.

American Wheatley offers a centrifugal type sediment removal separator to prevent the buildup of dirt in your system, which can lead to premature system failure. While the design is similar to the American Wheatley TAS Series Air Separator, the SRS Sediment Removal Separator also offers the advantage of solids removal. The tangential design allows for sediment removal through the vortex action, which forces suspended sediment to the outside of the vessel and into the bottom sump where it can be easily removed. The tangential action also creates a vortex that forces entrained air into the center, which is then removed through the top opening, vented to the atmosphere, or sent to the expansion tanks.

Bladder expansion tanks are needed in hydronic heating and cooling systems to absorb the expansion force that results from temperature changes of the heating and cooling fluid. This prevents water logging and air absorption as well as prevents excessive corrosion.

Chilled water buffer tanks are designed for chilled water systems with insufficient water volume capacity, in relation to the chiller capacity. Relatively low water volume systems require additional “buffer” capacity for the system to eliminate problems such as excessive chiller cycling, poor temperature control, and erratic system operation.

American Wheatley Flex Pump Connectors come in three categories: Rubber Flex Connector, Stainless Steel Connector, and Elastomeric Connector.

Y strainers, named for their “Y” shape, help prevent the mixing of any solids, pipe scale, rust, or debris with any liquid, gas, or steam flowing in a pipeline. American Wheatley offers a wide assortment of Y Strainers and Baskets, including Basket Strainers, Cast Iron Flanged, Fabricated Basket, Y-Type, Cast Iron Flanged, Y-Type CI & Bronze Threaded, Y-Type Stainless Steel Threaded, Fabricated Y-Type, and Fabricated T-Type. Our strainer materials consist of perforated stainless steel, which offers good corrosion and abrasion resistance as well as weldability and formability. Stainless steel strainers are often used in chemical and food-processing equipment.

The American Wheatley suction diffuser/flow diverter is designed to reduce space and installation costs by replacing the 90° elbow, strainer, and stabilizing entry pipe on the suction side of the pump. It can be directly mounted in a horizontal or vertical position, and includes a separate fine mesh startup screen surrounding each perforated screen.
