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 and supplied chart.  Take a pressure drop reading from the SUREFLOW supplied sensing tubes.  Next, use these readings to instantly acquire the actual CFM from the chart located on the side of the SUREFLOW economizer panel.  For other field adjustments, simply adjust the blade opening up or down until the pressure drop and CFM are in line with the supplied chart.

It's this type of simplicity, accuracy and dependability that continues to place Ruskin as the industry leader in providing products that save time and money.
