The use of condensation pan chemicals are used in refrigeration drain pans and are designed to control the slime producing bacteria that leads to plugged drain lines causing water to backup and overflow the condensate drain pan. Anti-Clog treatment products control toxic bacteria, control slime, and prevent sludge from forming in the drain pan. Maintenance of the condensate system is critical to prevent air born diseases caused by molds and bacteria as well as damage to wall, ceilings should an overflow occur. Anti-Clog is registered with the EPA and NFS International. This chemical has been proven to control the bacteria know to cause Legionnaires Disease and should be considered as an important measure to prevent air-born disease associated with HVAC equipment. 

When the condensation occurs within an HVAC system, it collects in the condensation pan, which can become a breeding ground for bacteria and mold. If left untreated, this can result in poor indoor air quality, unpleasant smells, and potential health risks for those inside the building. To address these issues, condensation pan treatment chemicals are specially designed to effectively clean the pan and prevent the growth of algae and mold. These chemicals typically contain biocides, cleaning agents, surfactants, and corrosion inhibitors not only too clean the condensate drain pans but also to protect the HVAC system from damage. At Cannon Water Technologies, we understand the importance of maintaining the efficiency and longevity of your condensation pans. That's why we offer a wide range of condensation pan treatment solutions, each designed to meet the specific needs of your systems.

Why Condensate Drain Pans are Essential in HVAC Systems?

Here are some key reasons why condensate drain pans are essential in HVAC systems:

  • Preserve System Efficiency: Accumulated condensate in the HVAC system can impede airflow and hinder the performance of cooling coils. This reduced airflow forces the system to work harder to accomplish and uphold the desired temperature, leading to increased energy consumption and eventually causing unnecessary strain on the system. Condensate drain pans are designed specifically to avoid all such situations by efficiently draining the excess water, allowing the system to operate at optimal performance levels.
  • Prevent Water Damage: HVAC systems generates condensation as a natural byproduct of the cooling process. Without a properly functioning drain pan, the condensate will accumulate and overflow, leading to costly water damage to the surrounding areas such as ceilings, walls, and floors. The drain pan collects and safely removes this excess condensate, preventing any potential water damage.
  • Comply with Building Codes and Regulations: Many building codes and regulations demands the installation and proper maintenance of condensation pans in HVAC systems. Compliance with these standards is not only essential for ensuring the safety and well-being of occupants but also for avoiding potential legal and regulatory issues.
  • Prevent Equipment Failure: Excessive condensate levels can cause damage to critical HVAC components, including motors, cooling coils, electrical connections, fan blades, among others. The drain pans act as a safeguard by catching any water that may otherwise come into contact with these crucial components and cause corrosion, short-circuits, or other malfunctions.

How it works:

Place the Anti-Clog unit with felt pad into the drain pan so that the pad is in contact with condensation water. The chemical will slowly dissolve into the water effectively controlling the formation of bacteria keeping the drain lines free and clear to prevent clogging of the drainage system.
