Ruskin Company

Ruskin's EFAMS electronic fan-inlet air measurement station utilizes thermal dispersion technology combined with low-pressure drop aerodynamic sensors to measure the airflow at the highest velocity point in the system. This lower pressure drop equates to lower cost of operation over the life of the building when compared to other fan inlet devices. The Ruskin EFAMS features and benefits: • Can be retrofitted into existing systems where space does not exist for traditional air measurement devices. • Includes a minimum of two sensors, a router and transmitter box with LCD display showing both temperature and air flow velocity or volume in either FPM, CFM or Meters per second or Liters per second. • Easily field configured for any size fan. • The transmitter box provides two isolate 4-20 mA analog linear signal outputs representing measured air flow and temperature and shares the same platform as our EAMP, electronic air measurement probes. Ruskin's unique patented design provides lower pressure drop and accurate measurement of fan inlet air flow and inlet temperature. We are currently shipping the EFAMS with firmware version 8.6. With this release, calibration of the EFAMS air measurement station is accomplished on the installed fan using actual air flows. Our unique design does not rely on measurement of 100% of the air entering the fan, only measurement of an air flow that we know will track the actual air flow through the fan. The benefit is a more accurate air flow measurement (taking into account system effects) without adding a significant energy penalty, typical of most aftermarket fan inlet air measurement devices. The EFAMS is a great product! Proven to be rock solid, highly accurate and repeatable.

The ADH22F Double Skin Access Door is a galvanized steel access door for use with insulated duct work and features: Easy-bend tabs for quick, easy installation wherever fiberglass duct access is needed. Manual locks, assuring tight door closure. Continuous, piano-type hinges that give smooth operation.

Breakaway connections are required in order to allow the ductwork connecting to a fire rated damper sleeve to "breakaway" from the damper sleeve thus leaving the damper within the fire rated opening maintaining the integrity of the wall or floor. The connection point of a damper sleeve and ductwork requires a UL approved breakaway connection. There are a number of field constructed approved breakaway connections listed on our standard installation instructions. The following are "flanged breakaway connections" that are UL approved for us as breakaway connections if installed per the installation instruction supplement. Ductmate, Ward, Nexus, TDC and TDF

Ruskin has the most comprehensive line of air measuring and control solutions in the industry. Products include differential pressure probes for high velocity applications, combination units that measure and maintain flow, and highly sophisticated, intelligent solutions that incorporate thermal dispersion technology with microprocessor based controls that communicate with any building automation system. Products are available in anodized aluminum, galvanized steel, and stainless steel construction to meet job-specific requirements. Product performance data are based on testing performed in accordance with AMCA standard 500D.

EnERVent+ models EVT-010 and EVT-019 energy recovery ventilators are designed for outdoor rooftop installations with a downflow or horizontal configuration. The rotating enthalpy wheel provides preconditioned outside air back into the system reducing energy costs. These models offer double wall construction and the option of auxiliary heating and cooling capabilities. Model EVT-010 is used in applications requiring a 600 - 1000 CFM range or use the EVT-019 for applications requiring an 800 - 1900 CFM range.

Ruskin access doors enable access into ducts without compromising safety or ventilation. Ruskin has a wide variety of doors to meet different duct styles and application needs.
