Dry Coil Evaporator for Cleanroom Application

Dry coil evaporator is a heat exchanger used to remove heat from air in a cleanroom environment without producing condensation. It's critical for maintaining the precise temperature and humidity control required in cleanrooms, ensuring the cleanliness and integrity of sensitive processes and products.

Function:

Cooling:

The dry coil removes heat from the air by transferring it to a cooling medium (usually chilled water).

Dehumidification:

By maintaining a higher chilled water temperature than the dew point of the air, it prevents condensation and excessive humidity.

Temperature Control:

It helps regulate the temperature within the cleanroom, ensuring it remains within the required parameters.

Energy Efficiency:

Dry cooling coils can be integrated into energy-efficient HVAC systems, optimizing overall energy performance.

Key Features in Cleanroom Applications:

No Condensation:

The chilled water temperature is maintained above the dew point to prevent moisture formation.

Optimal Airflow:

A recommended face velocity of 2 m/s is often used to maximize heat transfer efficiency.

Drain Pan:

While a condensate drain pan is not typically needed in a dry coil system, it might be necessary in high-humidity situations or if the pipe insulation is inadequate.

Versatile:

Dry coils can be used with various cleanroom HVAC systems, including Main Air Units (MAUs).

Precise Control:

They enable precise temperature control and can be integrated into energy-efficient HVAC systems, optimizing overall energy performance.
