Ruskin Brings Comfort to Medical CenterThe owners of St. John Medical Center in Tulsa, OK find comfort in knowing their emergency generator system is protected by Ruskin. A newly built penthouse using Ruskin’s Wind Driven Rain Resistant EME6625 Louver keeps the top-floor generator room dry and secure.
Designed to handle the severe weather conditions often found in the Midwest, the EME6625 Louver creates very low pressure drop while providing the best combination of rain protection and high airflow capacity.
To meet an increase in demand for medical services, the owners of St. John Medical Center recently expanded their complex — including the 500 bed hospital. Located in the heart of Tulsa, OK, the medical center is subjected to the threat of rain throughout the year with occasional large hail and violent windstorms.
The new medical center expansion included a state-of-the-art emergency generator system located on the top floor. This meant that large intake openings had to be placed on the rooftop to feed ...

Ruskin Has the SolutionTo protect the openings, a 54' x 15' x 5' tall vertical blade Wind Driven Rain Resistant Penthouse was mounted above the generator room. The penthouse solution was designed by Keith Browne of Lee and Browne Consulting Engineers using Ruskin’s Wind Driven Resistant EME6625 Louver.
The engineers chose this Ruskin louver because they were able to design a structure that creates very low pressure drop and provides an excellent combination of rain protection with high airflow capacity.
“The emergency generator installation which the penthouse serves has an intake air flow requirement of 375,000 CFM,” says Keith. “The vertical blade design offers enhanced performance versus traditional horizontal blade louvered penthouses.”
The hospital’s new penthouse is the largest ever built by Ruskin using a Wind Driven Rain Resistant Louver. These louvers have been specifically designed and tested in the AMCA Wind Driven Rain Test for use in the most severe weather conditions.
With the performance of ...

Automated dampers help save time and money
(KANSAS CITY, Mo.) – With the introduction of their complete line of automated Economizer dampers and power exhaust units for rooftop air handlers, Ruskin the HVAC industry's leading provider of dampers and louvers, has entered the Economizer business. Ruskin's dampers range from 3-25 ton and are suitable for both horizontal and vertical applications.
Featuring Ruskin's exclusive one-piece galvanized airfoil blade and stainless steel jamb, the Economizers provide low-leakage performance as described in ASHRAE Standard 90.1. Each unit also features Ruskin's “SUREFLOW” sensing tubes and blade position indicator to help determine minimum air flow. This also helps assist in mixed air temperature verses blade position field adjustments.
Determining accurate minimum air flow using the SUREFLOW system is easy. Using the current percent of required make-up air and fan system CFM, take note of the blade position from the indicator ...
