West Ward DX Case Study

Type of Facility and Location:

Primary Issues:

The mechanical system servicing the manufacturing space could no longer maintain the proper temperature and humidity levels necessary for ongoing operations.
Provided a system performance restoration in order to avoid a $500,000 replacement capital expense, and costs associated with a lengthy operational downtime of system replacement.

Type of System:

The mechanical system included a single 100 ton HEPA filtered AHU with an 8-row coil approximately 4 ft. by 8 ft.
The dedicated air-cooled chiller plant sat directly adjacent to the AHU and was powered by a 480-volt 3-phase bus.

Pre-cleaning Condition of System:

The ambient type of particulate was a fine powder.
The chilled water coil appeared to be visibly clear.
There were multiple banks of Merv 8 and Merv 12 filtration in front of the coil and a bank of HEPA downstream from the coil.
However, airflow testing across the coil confirmed several blockages that were greatly affecting unit performance.
The chiller plant itself showed heavy contamination in the condenser coils and was constantly running all four compressors with high head pressure to achieve a 41 degree chilled water output temperature.

Services Performed:

Both the chilled water coil inside the AHU and the bank of condenser coils for the chiller plant were cleaned with the patented Biomik Process which incorporates:
Multiple alternating courses of high pressure “wet steam” and Biomik Coil Cleaner.
A post-cleaning Biomik Protective Coil Spray is applied.
