Ask for the Blue Label: Why Contractors Choose JJM Condensate Neutralizers

As energy regulations continue to increase, more and more high-efficiency, gas-fired heating appliances are being installed in retrofits and new construction to meet the new standards, lower energy consumption, and improve performance. However, these condensing furnaces, boilers, and hot water heaters produce a byproduct that, if it’s not properly treated, can damage the plumbing system and the environment.

This residue, known as acidic condensate, is produced in high-efficiency, gas-fired appliances when their secondary heat exchanger extracts heat from the combustion gases, which then cool into a liquid. Unlike air conditioning condensate, this liquid has a low pH level—often between 2.9 and 4.0 pH, which makes it corrosive to concrete foundations, floor drains, plumbing, and wastewater infrastructure. Vegetation and groundwater do not like this stuff either.

Untreated acidic condensate can be a real problem, but condensate neutralizers are the easy, purpose-built solution. In fact, due to recent code developments, most jurisdictions now require a neutralizing device to treat this acidic condensate. Not all condensate neutralizers are created equal though...

As the industry pioneer, JJM Alkaline Technologies® has been supplying HVAC and plumbing industry pros with reliable, purpose-built condensate neutralizers to effectively treat acidic condensate for 20 years. But why is JJM® one of the best condensate neutralizer brands on the market?

JJM Alkaline Technologies celebrates 20 years as the trusted leader in condensate neutralizer innovation.

Why is JJM® the best condensate neutralizer brand?

JJM® was established in 2005 by its founder, George Carney, in Massachusetts when George noticed the issues with acidic condensate from the condensing boilers emerging at the time. In his home garage, George designed JJM®’s first generation condensate neutralizer that was purpose-built to treat acidic condensate on high-efficiency installations. We built the pHirst one. Now, we build the best ones.

Today, JJM® is the leading designer and manufacturer of condensate neutralizers for the heating and plumbing industries. JJM® offers the broadest portfolio of condensate neutralizer solutions on the market across residential and commercial installations. JJM® products are designed with industry pros in mind: versatile to install, quick and easy to service, and purpose-built for specific applications, like tankless water heaters. Not to mention, JJM® provides contractors with field training and responsive support. Importantly, JJM® condensate neutralizers are still Made in America.

What are the best condensate neutralizers for energy-efficient gas furnaces and tankless water heaters?

JJM® continues to develop new, innovative solutions that HVAC and plumbing industry pros trust to protect facilities and the environment.

For example, the JJM® NBT-400P is one of the best condensate neutralizers for energy-efficient gas furnaces. Equipped with a built-in condensate pump, the NBT-400P model provides an all-in-one solution for efficient neutralization and disposal to a remote drain. This model is popular with HVAC pros because it is designed to handle both acidic condensate and non-acidic condensate from the coils. In addition, the NBT-400P features a removeable tray that ensures quick and easy replacement of the pH Power Pellets® media without disconnecting any fittings.

Similarly, the JJM® V-200 condensate neutralizer is the best condensate neutralizer for tankless water heaters. The V-200 model is purpose-built for condensing wall-hung boiler and tankless water heater installations where floor space is limited. With its vertical-mount design, the V-200 provides installation flexibility with two optional outlet ports, enabling versatile outlet piping configuration. The innovative end-cap design allows technicians to service the condensate neutralizer without disconnecting any fittings.

JJM® condensate neutralizers are built with pH Power Pellets®, JJM®’s proprietary neutralizing media found exclusively in JJM® products. Like any filtration device, condensate neutralizers must be routinely serviced to maintain effectiveness and performance. JJM® condensate neutralizers, like the NBT-400P and V-200, are designed to be quickly and efficiently serviced. Furthermore, pH Power Pellets® refill kits are individually weighed and packaged for each JJM® condensate neutralizer model, which ensures quick and accurate service every time.
