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

4l/mn

0,1 ppm ASHRAE 110: 1995

determine the most important safety test for fume hoods:

Containment of the chemicals in the enclosure


0,5 m/s

High internal

turbulences

Fragile air barrier !

Narrow duct hole


Escape of chemicals

Questionable containment ! =

Questionable safety !

A/C

External turbulences

0,5 m/s

Fragile air barrier !


Sash up to work

conveniently =

No protection

of the chemist !

inappropriate ergonomical design !

Sash design straight !


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 !


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…….


* 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 !


=

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 !


How about these handlings on the

benches ?

Lack of flexibilty !


Canopy hoods over the working benches ?


No enclosure =

No containment

= No

safety!


Installing more fume hoods

on all the benches ? Enormous

energy consumption

and very questionable

safety ! !


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 !


Filtration fume enclosures ! An alternative to the ducted

systems ?

chemicals)

Which criteria can make them safe ?

3- Air face velocity:

2- Containment:

1- Filtration efficiency:

according to NFX 15-211 ANSI/AIHA Z9.5:2003 OSHA Part 1910.1450

SEFA 1.2-1996 0,4 – 0,6 m/s

according to ASHRAE 110:1995 test 0,1 ppm SF6

according to NFX 15-211 SEFA 9

1% of PEL

1- Air face velocity 0,4 to 0,6 m/s obtained through ergonomical sash openings

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

1% of PEL max. at filter exhaust

PEL = Permissible exposure limits

Long term danger

Issued by NIOSH in USA

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

1% of PEL max. at filter exhaust

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


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 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


User identification for

a controlled safety

Filter column with revolving filter change

Safety filter

Detection chamber

Main filter


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


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

A success story in USA and Europe !

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.”
