Lochinvar & A.O. Smith 100291509 Anti-Scale System

Lochinvar & A.O. Smith 100291509 Anti-Scale System

The Lochinvar & A.O. Smith 100291509 Anti-Scale System, also known as the PP-AS20, is a standalone water treatment system designed to mitigate hard water scale in high-efficiency tankless water heaters and commercial boilers. Utilizing advanced Template Assisted Crystallization (TAC) technology, this unit converts dissolved calcium and magnesium minerals into inactive microscopic crystals. These crystals remain suspended in the water and pass safely through the heat exchanger without adhering to internal surfaces, maintaining peak thermal efficiency and preventing the restrictive buildup that leads to overheating and component failure.

Engineered for professional HVACR applications, this system features 3/4" NPT connections and supports a flow rate of up to 7 GPM with a maximum pressure rating of 100 PSI. The 100291509 operates without the need for electricity, salt, or chemical additives, making it a sustainable alternative to traditional ion-exchange water softeners. For veterans in the field, this means zero wastewater and simplified maintenance. For optimal performance, the replacement cartridge (PP-AS20R) should be swapped every two years, depending on local water hardness levels and aggregate peak demand.

Key Benefits

  • Prevents Scale Formation: Protects copper and stainless steel heat exchangers from mineral calcification using TAC technology.
  • Maintains Thermal Efficiency: Ensures consistent heat transfer and prevents the "insulating blanket" effect that increases utility costs.
  • Chemical-Free Operation: Does not add polyphosphates or salt to the water supply, preserving water quality for downstream fixtures.
  • High Flow Capacity: Handles up to 7 GPM, making it suitable for both residential and light commercial water heating equipment.
  • Simple Integration: Standard 3/4 inch NPT inlet/outlet allows for quick inline installation on the cold water feed.

Common Questions

Does this system replace a water softener? This is a scale prevention device, not a softener. It does not remove minerals but neutralizes their ability to bond to surfaces. It is ideal for protecting specific equipment where Traditional salt-based systems are impractical.

How do I know when the filter needs replacing? While the cartridge is rated for a two-year service life, high-volume applications or water with hardness levels exceeding 45 grains may require more frequent intervals to ensure continuous anti-scale protection.

Is this unit compatible with a recirculation pump? Yes, it can be used in systems with recirculation as long as it is installed on the cold water makeup line before the heater and a proper bypass is utilized for servicing.
