For more than a decade, Spirotherm, Inc. has worked with innovative engineers and contractors to provide customers with air-free hydronic systems. Spirotherm goes beyond the residential market with a client list that includes many Fortune 500 companies as well as leading educational campuses, health care facilities and commercial complexes. Supported by factory trained sales offices in most major cities, Spirovents can be found in thousands of systems throughout North America.

The Spirovent[R] uses the original patented Spirotube[R] design as the core to provide unsurpassed efficiency, eliminating all free air, all entrained air and up to 99.6 percent of the dissolved air in the system fluid. This coalescing medium or scrubber, combined with the engineered height of the vessel and proper selection criteria creates a velocity change within the unit allowing the air and dirt to break free of the flow path. At these low velocity conditions, the fluid is scrubbed to a level that allows it to return to the system in an oxygen-starved condition. Air pockets lodged throughout the system are then absorbed back into the fluid and carried to the Spirovent for release. The need for frequent bleeding, purging and venting is eliminated along with air-related system noises such as gurgling and the waterfall effect. Heat transfer is enhanced and the need for rust inhibiting chemical treatment can be reviewed.

Spirovents are available from 3/4-inch through 36-inch pipe sizes and will handle flows up to 30,500 gpm. Available in three configurations, they eliminate both air and/or dirt problems quickly and efficiently. Spirotherm products are readily available and engineered for years of trouble-free use in all systems. Satisfied users join the client list on an almost daily basis with extremely positive results. From maintenance savings to the elimination of tenant/student complaints to short payback ... Spirovent has provided the solution.
