Industrial Air System and Chiller

Wyeth-Ayerst Pharmaceuticals Building No. 38, Rouses Point, NY


Wyeth-Ayerst Pharmaceuticals built a chemical storage addition on its plant and needed to upgrade its ventilation system.

MEP designed the new mechanical system to include outside air ventilation to accommodate the needs of the new space.

Facility Description

Wyeth-Ayerst Pharmaceuticals plant consists of a total of 250,000 square feet and is located in Rouses Point, New York. The process compound is mechanically served by a central steam plant and centrifugal chillers with primary and secondary chilled water distribution systems. 

The project objective was to erect a 3,500 S.F. addition to the compound (Building No. 38). The chemical storage in nature addition needed to be served by a 25% outside air ventilation system.

Project Origin and Goals

As part of the design team working for a previous employer, Mr. German Chaikin PE was responsible to design the mechanical system for the project. An 8,000 CFM air handling unit with medium pressure steam and  secondary chilled water coils.

The project required the installation of a two stage steam pressure reducing station, two 9,000 lbs/hr. steam driven condensate pumps, chilled water piping, steam piping, steam unit heater, plant air, and all associated DDC controls.
