Fireside Universal Condensate Neutralizers

We manufacture “Clearly the best” Universal Condensate Neutralizer on the market for easy install, sight inspection, cleaning and refill. In fact, Other manufacturers try to design around our products, which makes us feel good.

Our pH neutralizing tubes are for treating acidic condensate produced by today’s high efficient condensing appliances.

We have the solution to the ever increasing demand for a neutralizing cartridge to reduce the acidity of today’s high efficiency gas appliances by NATURALLY increasing the pH level.

How Did We Come Up With Our Design?

Our neutralizer designs are the direct result of boiler and furnace manufacturers needs for a High Quality, Universal, Re-chargeable, and simple Condensate Neutralizer.  Our units are designed by a Master Plumber with years of experience in high efficient equipment. They are designed to be easy to install, highly functional and super easy to maintain.

We have 5 tube type model numbers to handle any size of boiler up to 1.2 Million BTU. All units are clear which makes it easy to see how the medium inside is holding up. No need to buy optional kits or union kits because our neutralizers have always been manufactured with integral 3/4″ o-ring unions so they are truly removable out of the box.  Our neutralizer accepts 3/4 PVC” , 1/2″ PVC or adapts to flexible tubing, so you really have any piping option you prefer.

We have the first and the best Fireside Universal Vertical install neutralizer on the market.  Our patent pending vertical design incorporates all of our standard features such as integral o-ring unions for maintenance but is mounted in the vertical position which is perfect for wall mount boilers and tankless water heaters.  Our vertical neutralizer also acts as a gas trap.  There are no socks around the media with our design, you get full contact with the media. Compare to the competition and you will see the difference!

How Are The Neutralizers Made?

The Fireside Universal Condensate kit contains a removable tube and the highest quality natural media. For quality purposes, we use media that is no less than 96% and averaging 99% pure calcium carbonate. The media is washed and dried for you and with our media, there is no need for added manufactured lime pellets full of fillers. They are not needed and they dissolve into a sludge that diminishes surface area which in turn slows and clogs the neutralizer. That is why other manufacturers have cumbersome bypass piping. Oh, and did we mention our products are made in the USA!
