Trapped air in chilled and heating hot water systems is the biggest source of problems we see in the HVAC industry: it forces pumps to work harder, less efficiently and more noisily. Air also contributes to corrosion, which introduces rust particles and debris into the HVAC water flow.
Dirt and air are both insulators so, in addition to the risk of added maintenance issues, an HVAC system with excess air and dirty water is one that is going to generate year-round headaches for building owners dealing with complaints about air that is insufficiently heated or cooled.
That’s why so many building owners don’t cut corners when it comes to products for separating and removing air and dirt from their HVAC systems. They opt for high efficiency, coalescing air and dirt separators, manufactured by Spirotherm.
Superior Air & Dirt Removal
Coalescing air elimination is a superior method of separating and removing dirt and air, and improving the overall water quality in HVAC systems. According to Plumbing & Mechanical, This method was developed in 1972, when Frans Roffelsen experimented with new types of heat exchangers using water-based test installations. “He found no brand of air eliminator available that removed enough air to avoid distortion of the testing results.”
“A research project eventually led to the creation of the Spirovent air eliminator. The special Spirotube inside the Spirovent proved to be the essential part that separated all air, including microbubbles, originating in the heat source. This enabled water to absorb even trapped air at remote and inaccessible areas.”
Spirotherm products have earned strong name recognition among building owners and their maintenance partners over decades of observable results.
In recent years, increased adoption has added to Spirotherm’s credibility in systems that have switched from the older method of tangential air separation systems. The differences are both obvious and subtle, from significantly changing water color and quieting pumps to the diminishing frequency of maintenance calls.
While you can’t avoid some air and dirt making its way into your system, you can minimize the effects with high-efficiency coalescing air separation products from Spirotherm. Sizes range from 3/4” to 36” pipe, and flows to over 30,000 GPM for residential, commercial, industrial, and institutional HVAC systems.
Improved Water Quality & Other Benefits
Here’s an overview of the key benefits of the coalescing system used in Spirotherm products:
- More effective elimination of air pockets and bubbles
- Removal of dirt particles as small as five microns
- Reduced risk of corrosion
- Reduced resistance that causes pumps to work harder
- Longer lasting seals and bearings
- Increased efficiency of boilers and chillers
- Improved heat transfer
- Overall system performance improvement
- Increased equipment life
- Energy Savings
How Spirotherm Works
Coalescing air separators work by slowing the velocity of water in the middle of the pipe where a separator is attached. As the bubbles are released from the slowing water they enter the separator, where they move through a coalescing media and rise to the top for release. At the same time, the dirt, which is heavier, falls to the bottom of the system where it can be removed via ball valve.
