Laboratory Specialists is committed to facilities that maximize lab safety and minimize energy consumption.

The predominant consumer of energy in a lab is the Lab Ventilation System.   Lab Variable Air Volume can minimize this expense, but relies on users to close the sash.  Experience shows that this often does not occur.  The New Tech Automatic Sash Positioning System removes the reliance on the user to close the sash the same way we have lights turned off automatically after everyone leaves a room.

This State of the Art Sash Closer Technology has been engineered to work with the users.  We are seeing competitor devices on the market that do not take these issues into account.  For Example:

• When users approach the hood face, the sash will begin to rise.  Users sometimes being impatient will assist the sash in rising, sometimes moving it rapidly.  With the New Tech ASPS this presents no issue.  Other technologies will not handle this situation as well, sometimes causing chains to skip a link or come off entirely, or cables to pull off of the pulley.
• When users leave a piece of glassware or other apparatus protuding from the hood, the sash closes on it.   Use of pressure sensitive tape is a competitor's approach to sensing an obstruction.  This can be problematic since the sash has to touch the obstruction to tell there is something there.  Not so with the New Tech system.

Use of the New Tech Automatic Sash Positioning System (ASPS) will:

• Maximize Safety - Keep Hoods closed per NFPA 45 6-8.3 - closed hoods are always safer than open hoods.
  
• Minimize Energy Costs - Enhance the Lab VAV or Two Position System with the addition of the New Tech Automatic Sash Positioner, reducing the volume of air that must be heated, cooled, humidified and dehumidified. This combination can reduce airflow by hundreds of CFM per hood.  Each Annual CFM saved will reduce operating (energy)  costs by about $4 to $6 per year.   
• Reduce Demand on Facility Infrastructure -  Your facility design will require smaller Heating, Cooling and Air Handling Equipment, reducing first cost.  In Retrofits, you will free up capacity of your existing system allowing the addition of new hoods without adding major equipment such as chillers, heating equipment, supply and exhaust fans.    
• Reduce your Carbon Footprint - Each Annual CFM saved, and again, this may be substantial, will reduce your carbon footprint by about 10 pounds per year.

  The US Dept. of Energy's Lawrence Berkeley Labs has estimated that a six foot 
  constant volume chemical fume hood consumes as much energy as three average homes.

  A VAV Hood that is left open, despite the investment in equipment,
  mirrors the energy use of a constant volume hood.
