Protecting your investment in high efficiency boilers, chillers, and other system components requires fluid to be distributed efficiently. Eliminating air and dirt increases efficiency, solving many maintenance problems, saving energy, and improving overall system performance and heat transfer.
Spirotherm manufactures industry-leading, high-efficiency Spirovent coalescing type air elimination products, the extended line of Spirotrap dirt separators, and Spirovent Quad hydraulic separators used in low loss header designs – all of which feature a 20-year warranty. Sizes range from 3/4” to 36” pipe, flows to over 30,000 GPM for residential, commercial, industrial, and institutional applications. As a wholly owned subsidiary of Spiro Enterprises, Spirotherm has developed and manufactured products that improve water quality in the HVAC industry since 1990.
Maddock Industries represents Spirotherm throughout Chicago, Illinois and Indiana. Maddock’s factory-trained Spirotherm experts can demonstrate how Spirotherm can protect your hydronics investment and save you money.
Spirovent Coalescing Type Air Eliminators
Using the patented Spirotube coalescing medium, Spirovent air eliminators, “scrub” the air from the system fluid and allow it to break free in a low velocity, low turbulence removal chamber. Simple to install with a straight in-line, full-flow design, Spirovent is available in residential and light commercial applications from 3/4’ to 2” pipe size with solid brass construction, integral patented air release mechanism, and a 20-year limited warranty. All models are rated for 150 psig at 270°F and, with flanged connections, are fabricated and stamped in accordance with ASME standards. Solar (HT) models are rated to 360°F.
Spirovent models are available in the following configurations:
- NPT (VJR)
- Sweat (VJS)
- Press fit (VJP)
- Horizontal (VJR / VJS / VJP)
- Vertical (VJV)
Commercial series VSR and VHR units are fabricated steel and available from 2” through 36” pipe size and flows to over 30,000 GPM. Custom fabrication is available for special project requirements. For large, high-velocity systems, the VHR Series is designed specifically for central plants and district heating or cooling systems where large volumes of water are being distributed.
Spirotrap Dirt Separators
Primarily applied in open condenser water systems, the Spirotrap dirt separator uses the patented Spirotube medium to create a low velocity, low turbulence dirt separation chamber. Dirt and sediment are 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, Spirotrap eliminates the need for high maintenance sidestream filters.
Recommended by many high efficiency boiler manufacturers, Spirotrap is available in the brass TDN Junior Series for residential and light commercial applications from 3/4″ 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. Custom fabrication is available for special project requirements. 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.
A user-specified removable head is available on TDN and THN models for access to the Spirotube bundle for inspection or cleaning.
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’s available in brass from 1″ through 2″ and steel through 12″ as standard products. Larger custom sizes can be reviewed per application.
Spirotherm’s patented coalescing element and dirt separation medium completely fills the internal volume of the vessel providing unsurpassed efficiency. For units 1″ through 1½”, powerful magnets surround the flow path to separate ferrous material. Connections have been engineered and placed to allow for hydraulic balance.
The unique construction of this combined unit allows for the removal of both entrained air and dirt particles. Sprirotherm’s patented Spirotube, the core of the Spirovent Quad unit, causes air bubbles to rise and collect in the low turbulence air separation chamber before being released via an integral automatic valve. Dirt and sediment sink through the low velocity, low turbulence separation chamber to the bottom of the unit, eliminating any blockage concerns.
