Advantages of UniFlow CAV By-Pass Fume Hoods

Cut Energy Costs up to 50%, by reducing the size of the blower & ductwork required, while lowering installation costs.

• Important: by incorporating Sash Management 1-2-3, you are saving on overall energy costs, and protecting the fume hood user.   • The Sash Stop is designed for user protection and cfm reduction. Allows sash to open to a maximum of half open, providing up to 50% energy savings.
1. Recommended that hoods be used with sash 1/2 open with face velocity of 80-100 fpm. Sash stop can be located to suit. With lower sash closed and upper sash raised to the 1/2 open position the supply air cfm & static pressure are as noted.   • Sash at full open is primarily designed for set-up of equipment and maintenance. Fume hood users should wear personal safety protection equipment, consult Lab Safety Officer.

2. Sash in full open position should be for setup of apparatus & maintenance service only. If design opening is at 1/2 open at 100 fpm, face velocity at full open would be approximately 50 fpm. Therecommended face velocity for efficiency & safety is 80-100 fpm. Lower face velocity may compromise user safety.

  • HEMCO recommends 10-12 room air changes per hour for the health & safety of personnel. Example 10’ X 20’ room 10’ high receiving 10 room air changes per hour requires 350 cfm.
3. When hood is not in use, keep sash in closed position.   • At an average utility rate of $7.00 per cfm, a typical annual savings on a 4’ fume hood would be $2705.00 and on a 6’ fume hood $4067.00, by using Sash Management 1-2-3., Sash Stop at 50% open.
• Sash stops are standard on U.L. Classified Fume Hoods    

Traditional Fume Hoods vs UniFlow Fume Hoods

Innovation is the Difference Between the Same Perspective and an Entirely New one.

   
  The 1925 Ford Tri-motor, featured all metal construction, no wood. Its fuselage and wings were constructed of corrugated sheet metal, for strength. These aircraft were well-designed, and reliable (for the era).   The Boeing 787 Dreamliner features aerodynamic composite construction. Composites have a higher strength to weight ratio, which helps to make the 787 a lighter more energy efficient aircraft.
Traditional Fume Hoods   1. Fully Assembled Fume Hoods   UniFlow Fume Hoods
 

Traditional Fume Hood 60” wide Constructed of formed painted sheet metal panels & held together with sheet metal fasteners & brackets. Chemical resistant interior liner panels with sharp corners sealed with caulking.

Customer Comments:
Hoods, based on the nature of the products we analyze (sulfur chlorides, sulfuric acids, oleums), last about two to three
years. At the end of three years, the chemicals have corroded both the exterior steel panels and the internal steel frame work of the metal hoods. We replaced them eight years ago with HEMCO UniFlow fiberglass fume hoods the installation was easier and we have had no repairs since then. We are building a new facility, and we plan to install HEMCO hoods.
