Preheat Coil Replacement and DDC Controls Installation


National Institutes of Health (NIH)

air handling unit coil

This mechanical installation project was located on the main campus of the National Institutes of Health in Bethesda, MD. The building houses clinical research and animal care facilities, offices and other mission support areas. The preheat coils located on two of the air handling units had failed and ruptured and needed replacement. GMS performed the mechanical installation of the coils and also replaced the existing pneumatic control devices associated with the air handling units with direct digital controls (DDC) for compatibility with Siemens controls.
