Green laboratories: Saving energy and Protecting

Environment

with Advanced Filtering Fume Hoods

and Filtering Storage Cabinets ……  

……while providing

improved safety to the chemists ……..

What is the situation today !  

Most systems are ducted !  

….requiring extremely complicated ductworks and auxiliary air supply systems!  

Ducted systems: for which result ?  

8-Air conditionning/

7-Filtration

6-Automatic

adjustment

3- Blower for extraction of

the polluted air 1000-2500 m3 /h

4- Blower for Introduction of auxiliary air

1000 – 2500 m3 /h

1-Fume Hood

2-Duct to the roof

5-Duct to lab room

Expensive to install and to

maintain !  

SF6 gas

0,1 ppm ASHRAE 110: 1995

determine the most important safety test for fume hoods:

Containment of the chemicals in the enclosure

Ducted systems: for which result ?  

0,5 m/s

High internal

turbulences

Fragile air barrier !

Ducted systems: for which result ?  

Very high energy consumption !  

A/C  

1000 – 3000 m3/h

1000 – 3000 m3/h

In USA one Ducted Fume Hood working 8 hours a day,

220 days a year, has an estimated

energy consumption (aircon air) of

US$ 5000 per year !

Ducted systems: for which result ?  

h"p://fumehoodcalculator.lbl.gov  

Lawrence  Berkeley  Na=onal  Laboratory  (California-­‐USA)  developped   a   Laboratory   Fume   Hood   Energy  Model   to  calculate  energy  consump=on  of  fume  hoods  

         Calcula=on  criteria  :      -­‐  Fume  hood  air  flow    rate  -­‐  Fan    efficiency  -­‐  Cooling  system    type  -­‐        Hea=ng  system  type  -­‐  Temperature  outside/inside  -­‐  Energy  price  -­‐          etc…….  

Ducted systems: for which result ?  

*  There  are  around  750  000  Ducted  Fume  Hoods  in  USA                consuming    approx.    4,2  billions  US  $  !!    

*  Energy  consump=on  of  a  Fume  hood:                                                  4600  US  $  per  year  in  Los  Angeles                                                  9300  US  $  per  year  in  Singapore    

*  One  Fume  Hood  consumes  as  much  energy  as  a              house  250  m2  !  

Ducted systems: for which result ?  

=

Possible re-entry of the polluted air into the building

through the ventilation inlets on the

building’s roof

A/C  

Pollution of the building

environment !  

Ducted systems: for which result ?  

How about these handlings on the

benches ?

Lack of flexibilty !  

Ducted systems: for which result ?  

Canopy hoods over the working benches ?  

Ducted systems: for which result ?  

No enclosure =

No containment

= No

safety!  

Ducted systems: for which result ?  

Installing more fume hoods

on all the benches ?  Enormous

energy consumption

and very questionable

safety ! !  

Ducted systems: for which result ?  

0,5 m/s

Using VAV (Variable Air Volume) Fume Hoods

to save energy ?  

VAV VAV

200 m3/h 200 m3/h 1000 m3/h 1000 m3/h

3000 m3/h 3000 m3/h

Expensive, complicated to

install, difficult to amortize,

User dependant, very questionable

containment capacities !  

Ducted systems: for which result ?  

Filtration fume enclosures ! An alternative to the ducted

systems ?

0,4 to 0,6 m/s

2 - High containment efficiency obtained through a smooth « laminar » airflow in

the enclosure

Turbulence free airflow !

SF6      requirement   Obtained  0,1  ppm   0  ppm  !!!  

2- High containment efficiency

NFX 15-211 SEFA 9

3 - High filtration efficiency guaranted through compliance with demanding safety

standards !

Average concentration of a chemical inhaled

over 8 hours per day

NFX 15-211 SEFA 9

Chemical   PEL  (OSHA)   Filter  exhaust  Toluene   200  ppm   2  ppm  only  

max.  Formic  acid   5  ppm   0,05  ppm  only  

max.    

3 - High filtration efficiency

Chemical   Filter  exhaust   Quan=ty  retained  

Toluene   At  2  ppm  max.   1380  g  Formic  acid   At  0,05  ppm  max   1235  g  

4 - Filtration capacity to be specified by manufacturer

5 - Third party official testing required

Slanted sash to help for

a good vision and

a perfect protection  

Comfort and all time safety at work through an adequate ergonomical design !  

Main benefits !

No exhaust of aircon air to outside: 100 % energy saving !

No duct ! Total mobility, protection close to user !

Main benefits !

Chemicals vapors retained in filters ! No pollution to outside !

Main benefits !

Filtering storage cabinets: additional benefits !

No harmful smell when opening

the doors !

24 hours air cleaning of the room

Filtering storage cabinets: additional benefits !

Reduce the air-exchange rate of the lab and save very high

energy costs

10 x air exchange rate 5 x air exchange rate

Example of a room 240 m3: Saving per year (USA): around 15,000 USD !

Filtering storage cabinets: additional benefits !

Filtering fume hoods : a wide variety of applications !

Stirring ! Sampling !

HPLC ! Rotary evaporator ! Educating !

Transfering ! Weighing !

…….and many others !

New generation of filtering fume hoods

What makes them new ?

Powerful NEUTRODINE® filter for multi-disciplinary

handlings

What makes them new ?

User identification for

a controlled safety

Filter column with revolving filter change

Safety filter

Detection chamber

Main filter

What makes them new ?

Remote monitoring in real time for up to 250 GreenFumeHoods in the same building

What makes them new ?

Can replace up to 80% of the ducted fume hoods in new lab buildings

Filtering fume hoods and storage cabinets

with today’s technologies :

-  Complying with the standards: (SEFA9, NFX 15-211, ASHRAE 110,….) -  With manufacturer support and commitment -  with good user education

-  can replace many of the ducted systems -  can help to reduce the air exchange rate

-  can help to improve dramatically the safety of the chemist -  can help to save enormous amounts of energy -  can help to protect environment

“It  seems  safe  to  assume  that  the  enormous  benefits  inherent  in  the  filtering  fume  hood  will  drive  not  only  the   improvement   of   filtra9on   technology,   but   the  gradual  acceptance  of  this  approach  by  hood  users  in  industry   and   academe.   This   revolu9on   will   be  expedited   if   we   collec9vely   embrace   the   idea   of  change   and   think   about   how   we   can   and   should  incorporate   new   and   greener   technologies   and  prac9ces  in  our  labs.”
