S-4 Upgrade

The S-4 air handling unit supplied air to core areas located on five floors of the Medical Center. Installed in 1977, the hospital asked Hayward to rehab and modernize the unit. New steam and chilled water coils were installed along with custom fabricated stainless steel drain pans. The removal and installation of the new coils required the removal of part of the existing housing. New panels were fabricated in Hayward’s shop and installed. RBH custom fabricated and installed air diverters up stream of the new chilled water coil to achieve the desired air velocity reading. We also fabricated and installed custom moisture eliminators of Hayward’s own design downstream of the coil to catch the moisture carry over. The old roll-a-mat filters were replaced with a bank of 2’x2’ throw away filters in custom built frames. All pneumatic dampers were replaced with modern dampers which are controlled by a new combination of pneumatic and digital control system.

Upon completion of this complex and intricate project, University of Illinois honored Hayward with the Ventilation Contractor of Year Award. This award recognizes our ability, quality, and safe work habits over the course of the project. Hayward is very proud and honored to be recognized with the University’s award.
