Why Treat Condensate Drain Pans

 Drain pans can fill with slime, gunk, and disease-causing bacteria. This build-up comes from:

right

Condensation: Cooling equipment creates cold air by passing warm air over cooling coils. This causes condensate (water droplets) to form and flow off equipment coils — Think of a glass of ice cold ice tea on a hot summer day.

Drainage: Moisture from commercial cooling equipment is required to drain into a pan inside the unit to prevent condensate dripping out onto passerby and other objects. These pans are connected into drainage systems which is a potential cause for concern.

Bacteria: Slime is a by-product of bacteria which occurs naturally in water. Slime can build up and clog drain holes, causing the pan to overflow and potentially cause water damage. This also causes an ideal breeding ground for bacteria.

The Petri-dish Effect: Warm, standing water in pans work like Petri dishes, cultivating bacteria and potentially dangerous microorganisms. The equipment’s fan can then blow out the microbes into the facility degrading air quality and causing health risks.

General Condensate Drain Pan Treatment Information:

How to install condensate drain treatmentsinstall

  • Typically, treatments require that you place tablets or pan pads in the middle of the pan length. The product should begin working immediately after contact with water.
  • Be careful that the treatment product is chosen with consideration of the drain size. You do not want a treatment to clog the drain hole and cause overflow. This is especially important for products that require you to remove an expended treatment dispenser.
  • Each treatment should come with product specific instructions or be provided to you by the supplier.
