The Tri-Stack system solution to pollution abatement and odor control Job proven and time tested: The right place for your building exhaust stack designs help provide a research laboratories at S. trobic Air Tri-Stack two year payback when used universities, pharmaceutical, exhaust for centrifugal fan chemical and petrochemical Systems are replacement. Other organizations. They're also practical, cost- advantages of Tri-Stack ideal for exhausting effective and Systems include low profile hospital/infirmary isolation energy efficient design, low noise levels, rooms (or research HEPA filtration system solutions for variable air volume control laboratories and For special medical/pharmaceutical applications such as isolation room and pollution and vibration free operation at pharmaceutical production quarantine room exhaust, Level 4 safety laboratories, or similar applications, bag lower operating costs.)

5 Tri- facilities) where 100% in/bag out HEPA filtration Systems are available for Tri-Stack Systems . abatement, re- entrainment and Stacks are also virtually conditioned makeup air is odor control maintenance-free, offering usually required, and for problems. Tri- significant cost savings with emergency diesel generator stack fans and regard to maintenance labor, exhaust to prevent re- Systems are used while eliminating the need for entrainment and eliminate at hundreds of rooftop penthouses and odor in the neighborhood. In facilities, serving expensive vibration prevention fact, Tri-Stack Systems should as direct replacements for hardware. Direct drive motors be considered wherever issues conventional centrifugal exhibit up to 200,000 hour of exhaust pollution , odor exhaust fans which are usually lifetimes, eliminating the need control, re-entrainment, associated with tall, unsightly to replace belts, pulleys, or aesthetics and energy other limited life components.

6 Savings are important. Fans for high temperature stacks. Lightweight, modular construction with lower system environments Tri-Stack Systems are designed pressures (typically 2 ) for use at hospitals, Tri-Stack fans are also available in rigid steel construction for many high than conventional exhaust temperature applications such as emergency diesel generator, furnace or boiler biomedical facilities and room exhaust. Fans can withstand up to 750 F temperatures without the need for outside air dilution, and incorporate chemical resistant high temperature coatings. A brass rub ring on the inlet bell conforms to AMCA "C" spark resistance specifications. Tri-Stack TS Series roof exhaust fans Sizes, capacities and The Tri-Stack TS-2 roof exhaust fan provides configurations for virtually up to 18,500 CFM with any pollution abatement and static pressures of ". odor control application maximum and Retrofit applications motor horsepowers ranging from 5 to 15. Replacing outmoded centrifugal fans with Tri-Stack fans is practical, convenient, and cost-effective.

7 One manifolded Tri-Stack fan can typically replace up to 20. Tri-Stack Systems are designed for retrofit and individually dedicated stacks enhancing building aesthetics and eliminating negative implications associated with roof stacks. In addition to performance and new construction. They are available with operating cost advantages, retrofitting Tri-Stack Systems reduces engineering costs many different motor sizes to meet precise and eliminates extensive coordination of production/processing schedules to prevent unnecessary and expensive downtime. airflow and pressure requirements. Strobic 's technical/engineering staff will be pleased to work with you to determine the best possible Tri-Stack configuration for your application.

Value added accessories for enhanced Consider these outstanding advantages system performance offered by Tri-Stack fans and Systems : Maximize HVAC system performance, minimize noise at the property line Strobic Air offers a number of useful accessories for Tri-Stack fans including Systems to reduce energy consumption, provide even quieter operation through higher sound attenuation, and many special construction materials and/or coatings to accommodate unusual applications such as Prevent re-entrainment belts and pulleys; high ordinances governing operation in acidic, caustic and high temperature environments.

8 Many of these accessories are Tri-Stack Systems send a efficiency operation permits height of building exhaust described here. vertical jet plume of use of smaller horsepower stacks, Tri-Stack Systems are diluted exhaust gas up to motors; more efficient blade ideal for code compliance 350' high, providing design contributes to in virtually all cases. atmospheric disbursement quieter operation. In the Lower energy costs Direct Heat recovery Systems and preventing exhaust event that noise is a drive motors in Tri-Stack Unique glycol/water heat exchanger coil modules for Tri-Stack Systems extract from re-entering the facility problem, Strobic Air offers Systems use substantially exhaust heat for heating or cooling conditioned makeup air. (A 1 F rise in through fresh air supply a number of noise less energy per horsepower makeup air temperature permits a corresponding 3% reduction in heating costs, ventilation Systems , doors, attenuation accessories than comparable belt drastically lowering energy costs for savings of thousands or hundreds of and windows.)

Eliminate odor The dilution brochure. with mixed flow impeller capabilities of Tri-Stack fans Comply with architectural/ design energy consumption (up to 170% of free outside aesthetic ordinances Low is minimized. Based on air is introduced into the profile Tri-Stack Systems are current energy costs, a airstream above the roof), often not even visible from typical Tri-Stack system can effectively eliminate odors, the property line. As a provide a return on preventing them from result, problems associated investment (ROI) in less than entering the facility and with tall, unsightly stacks two years. In addition, for neighboring buildings. including the perception of applications that require Reduce noise at the property exhausting polluted air in conditioned makeup air, Acoustical silencer nozzles line Tri-Stack Systems are the neighborhood are Strobic offers accessory Acoustical silencer nozzles for Tri-Stack Systems attenuate up to 12 dBa for inherently quiet.

10 Direct eliminated with Tri-Stack heat exchanger Systems that quieter operation in particularly noise sensitive areas. Low profile design is drive motors are quieter Systems . Since many can significantly reduce unobtrusive, enhancing roofline aesthetics without affecting fan performance. than centrifugal fans with communities have strict energy costs. Acoustical silencer nozzles may be retrofitted onto existing Tri-Stack fans quickly and conveniently. Fan Family CFM Range Maximum Horsepower This Tri-Stack TS-3. Static Pressure Range roof exhaust fan incorporates an integral acoustical silencer Fans for harsh environments BS-002 3200 1 to 3 nozzle for highest attenuation in Tri-Stack fans are also available with special materials of construction and/or particularly noise coatings for use in caustic, corrosive and other severe environments (such as BS-005 4700 1 to 3 sensitive areas. chemical processing, plating and wastewater treatment facilities) where they may be exposed to nitric acid, fluorides, sulfuric acids and other high concentrations of caustic exhaust components.
