The AO Smith CNS-2 Condensate Neutralizer Kit (model number 100077608) is a crucial addition to any water heating system that utilizes a low pH or acidic condensate. This kit is specifically designed to neutralize the condensate produced by high-efficiency water heaters and boilers, ensuring the system maintains an optimal pH level for optimal performance and longevity.
The heart of this kit is the CNS-2 Condensate Neutralizer Tank, which is a compact, polypropylene tank with a capacity of approximately 0.5 gallons. The tank is designed to be easily installed in a convenient location near the water heater, and features a 3/4" NPT threaded inlet and outlet for simple connection to the condensate drain line.
The neutralization process is facilitated by the inclusion of a calcium hydroxide media, which is packed into the tank. This media reacts with the acidic condensate to produce calcium bicarbonate, effectively neutralizing the condensate and maintaining a pH level of approximately 7.0. The media has a large surface area and a long service life, ensuring that the tank can handle the needs of even high-volume systems.
This kit also includes an adjustable bypass valve, which allows for easy adjustment of the flow rate of the condensate through the neutralizer tank. This feature ensures that the system maintains the optimal flow rate for optimal neutralization and efficient operation. The bypass valve is adjustable from 0 to 100% and is designed to be simple to operate using a standard screwdriver.
The AO Smith CNS-2 Condensate Neutralizer Kit is an essential component for any high-efficiency water heating system or boiler that produces acidic condensate. It is designed for easy installation and long-lasting performance, and ensures that the system maintains an optimal pH level for optimal performance and longevity. With its compact size, simple installation, and effective neutralization capabilities, this kit is an indispensable tool for any water heating professional or DIY homeowner.
The AO Smith CNS-2 Condensate Neutralizer Kit (model number 100077608) is a device designed to neutralize the acidic condensate produced by water heaters. Here are some pros and cons that might help you make an informed decision about purchasing this kit:
Pros:1. Improves Water Heater Efficiency: Neutralizing the acidic condensate can help improve the efficiency of the water heater by preventing mineral build-up in the heat exchanger and reducing corrosion.
2. Extends the Life of the Water Heater: By neutralizing the condensate, the water heater is less likely to suffer from premature failure due to corrosion and mineral build-up.
3. Easy Installation: The kit comes with clear installation instructions and requires no special tools or skills to install.
4. Cost-Effective: Compared to the cost of replacing a failed water heater, the cost of this kit is relatively low.
5. Reduces Water Waste: Neutralizing the condensate can help reduce the amount of water wasted during the drain-down process.
Cons:1. Additional Cost: While the cost of the kit is relatively low compared to the cost of replacing a water heater, it does add an additional cost to the initial investment.
2. Regular Maintenance: The neutralizer will need to be periodically checked and maintained to ensure proper function.
3. Size: The kit may not be suitable for all water heater models and sizes. It is important to check the compatibility of the kit with your specific water heater before purchasing.
In conclusion, the AO Smith CNS-2 Condensate Neutralizer Kit can help improve the efficiency and extend the life of your water heater. While there are some cons, such as the additional cost and regular maintenance, the benefits outweigh the drawbacks. If you have a compatible water heater model and size, the kit is a cost-effective investment that can help save you money in the long run.
Therefore, if you own an AO Smith water heater and are experiencing issues with acidic condensate, or if you want to prevent potential problems, I would recommend considering the purchase of the AO Smith CNS-2 Condensate Neutralizer Kit.
