What is an Evaporation Pan?
How It Works: The Two-Step Process
Catching the Water (Condensation)
- During Cooling: The evaporator coils (the part that gets cold) pull humidity from the air inside the unit. This moisture freezes onto the coils as frost.
- During Defrost: To prevent this frost from building up and blocking airflow, the unit regularly runs a defrost cycle. A heater near the coils warms them up just enough to melt all the accumulated frost and ice.
- Draining: As the frost melts, the water drips down and is channeled through a drain tube, emptying directly into the condensate evaporator pan, which is located at the bottom of the unit.
Evaporating the Water (Disposal)
Unlike a home air conditioner that might have a drain line going outside, a self-contained refrigeration unit needs to get rid of this water on its own. It does this in one of two ways:
- Passive Evaporation (Using Waste Heat): Most commonly, the pan is placed near the unit’s hot components, the compressor and the condenser coil. The fan that cools these parts blows hot, dry air across the surface of the water in the pan. It’s a very efficient design that uses the heat the unit is already producing.
- Active Evaporation (Heated Pans): Some units in very humid environments produce more water than passive evaporation can handle. These models use an electric condensate evaporator pan. This pan has its own built-in heating element that warms the water, significantly speeding up the evaporation process to keep up with the load.
Evaporation Pan Benefits
Condensate Management
The pans solve the issue of condensate disposal when no drain is available.
Durable Materials
Our evap pans feature highly corrosion-resistant stainless steel material throughout. The float is made of electro polished 316 Stainless Steel and the rest of the components are made of 301/304 Stainless Steel.
Prevents Damage
Our evaporator pans help protect the refrigeration unit from rust and corrosion and also protect the floor areas from water damage.
