Clean Room Coils

The current explosion in the technology market has led to a dramatic increase in the number of manufacturing facilities utilizing clean rooms. Clean rooms are used in the fabrication of semi-conductors, electronic circuit boards and magnetic media (such as computer hard drives).

DRS Marlo Coil customers such as Samsung, Fujitsu, MEMC and Advanced Micro Devices have expanded their clean room specifications to reduce airborne particle contribution from all components within their ventilation systems. Since the coil plays a major role in these systems, reducing its ability to contaminate the air was essential to reaching today's stringent clean room air quality requirements.

DRS Marlo Coil has manufactured approximately 400-500 coils for clean rooms over the last several years with the following design criteria:

Heating or cooling coils for clean room coils typically feature wide fin spacings and efficient fluid circuits to offer low cost, continuous operation in recirculation systems. Most are designed for future increases in capacity as well.

Materials such as stainless steel and anodized aluminum are used to prevent corrosion of the coil which leads to offgassing of contaminants. Welds on clean room coils must be treated with cleaning and passivation agents designed to dissolve carbon deposits and seal the weld to prevent corrosion.

In addition, coils for these applications typically have multiple-stage cleaning requirements which keep the external surfaces of the coil clean during fabrication. De-ionized water or alcohol is used to clean individual components and the entire coil during fabrication and as a final wash.

Coils are then forced dry with clean, filtered air and packaged in clean plastic wrap for shipment or storage

DRS Marlo Coil manufactures custom coils to match material, dimensions, performance, cleanliness, and longevity to our customer's specific needs. Clean rooms are an excellent example of our ability to meet the requirements of a unique environment.
