Spirotherm

Spirotherm manufacturers the industry leading high efficiency Spirovent® coalescing type air elimination products and its extended line of Spirotrap® dirt separators. A wholly owned subsidiary of Spiro Enterprises, Inc. , Spirotherm has been developing and manufacturing products to improve water quality in the HVAC industry for almost 40 years. Sizes from 3/4” to 36” pipe, flows to over 30,000 GPM for residential, commercial, industrial, and institutional applications.

• Spirovent® Air / Dirt Separator: The Spirovent® Dirt and Drain Air Eliminator / Dirt Separator uses the patented Spirotube® medium to "scrub” the air and dirt from the system fluid and creates two low velocity, low turbulence separation chambers. Simple to install with a straight in-line full flow design it is available in the VDR, VDT, and VHT “Dirt” model as a sealed vessel and the VDN and VHN “Drain” model that includes a removable head and tube sheet construction.

• Spirovent® Air Eliminator: The Spirovent® Air Eliminators, using the patented Spirotube® coalescing medium, “scrub” the air from the system fluid and allows it to break free in a low velocity, low turbulence removal chamber. Simple to install with a straight in-line full flow design, it is available in the VJR, VJS, VJP and VJV Junior Series for residential and light commercial applications from ¾’ to 2” pipe size. Commercial series VSR and VHR units are fabricated steel and available from 2” through 36” pipe size and flows to over 30,000 GPM.

• Spirotrap® Dirt Separator: The Spirotrap® Dirt Separator, primarily applied in open condenser water systems, uses the patented Spirotube® medium to create a low velocity, low turbulence dirt separation chamber. Dirt and sediment is then able to break free of the flow path and fall to the bottom for blow down using the factory supplied ball valve. Simple to install with a straight in-line full flow design, it eliminates the need for high maintenance sidestream filters. Recommended by many high efficiency boiler manufacturers, it is available in the brass TDN Junior Series for residential and light commercial applications from ¾" to 2" pipe size. Commercial series TDT, THT, TDN, and THN units are fabricated steel and available from 2” through 36” pipe size handling flows to over 30,000 GPM. For large high velocity systems the THT and THN Series are designed specifically for central plants and district systems where large volumes of water are being handled.

• Spirovent Quad® Hydraulic Separator: Unlike other products, which are empty vessels or include only a baffle plate, the Spirovent Quad VDX combines the features and benefits of the industry leading Spirovent® air eliminator and Spirotrap® dirt separator with a center chamber between the four nozzles. Used primarily as a hydraulic separator in a low loss header design, it is available in brass from 1" through 2" and steel through 12" as standard products. Larger custom sizes can be reviewed per application. The patented coalescing element and dirt separation medium completely fills the internal volume of the vessel providing unsurpassed efficiency. The unique construction of this combined unit allows for the removal of both entrained air and dirt particles.

• Spirotop® Air Release Valve: The Spirotop® has a unique "dry" vent design that helps prevent the system fluid from reaching the spring actuated Viton® seat and seal assembly, which is the cause of most conventional air vent failures. The all brass, stainless, and non ferrous construction is rated at 150 psig at 270°F as standard and carries a 20 year limited warranty. For special applications, both high temperature and high pressure options are available.

Remove Harmful Black Sludge (Ferrous Oxide) from HVAC System Water

Spirotherm's SpiroCombi with Magnet not only removes 100% free, 100% entrained, and 99.6% of dissolve air, it also removes non-ferrous debris and ferrous oxide material (black sludge) using strong neodymium magnets.

Spirovent Air & Dirt Separators Remove 100% Free and Entrained Air and up to 99.6% Dissolved Air

The unique construction of the Spirovent Air & Dirt separator allows for the removal of both air and dirt particles from hydronic heating or cooling systems.

Improve Pumping Efficiency with a Spirovent Air & Dirt Separator from Spirotherm

Air and dirt have a negative impact on the performance of hydronic heating and cooling systems. Installing a Spirovent Air and Dirt Separator removes air and dirt, thereby improving pumping efficiency, reduce operating costs, protect critical system components and increase system reliability.

Improve Heat Transfer with Spirovent Air & Dirt Separators

Air in hydronic heating or cooling systems acts as an insulator on heat-exchanger and heating coil surfaces and reduces heat transfer efficiency. Air also causes corrosion, which produces debris that may clog the small passages of heat exchangers requiring costly repairs. A Spirovent Air & Dirt Separator, eliminates air and debris from the circulating fluid, resulting in increased efficiency and reduced maintenance costs.

Eliminate Corrosive Oxygen from Hydronic Heating/Cooling Systems with Spirovent Air & Dirt Separator

Air in hydronic heating or cooling systems contains oxygen. Oxygen causes corrosion, which in turn causes leaks and damages system components. A Spirovent Air & Dirt Separator, eliminates the air, and thus oxygen, and thereby preserves the system piping and increases the longevity of system components.
