Greenway provides heat transfer solutions as alternatives to fossil fuel-derived propylene glycol and ethylene glycol. Their bio-derived 1,3-propanediol called BIO PDO is produced from glucose through fermentation and has 42-56% lower greenhouse gas emissions and 38-42% lower non-renewable energy usage than synthetic alternatives. Greenway's organic corrosion inhibitors form a protective molecular film without degrading or altering heat exchange, offering long-term protection of systems without the use of boron.

Refrigeration / Heating / Renewable Energy
Greenway, long-term innovation

2. 1. Greenway® Innovation
Why change ?
Today: heat transfer mediums are
derived from fossil sources:
Propylene glycol (MPG) is used in
many applications (renewable energy,
heating, refrigeration, air conditioning)
Ethylene glycol (MEG) is mainly
used in industrial refrigeration

3. 1. Greenway® Innovation
Why change ?
MPG must be approved where there is a risk
of contact with food products
MPG has high viscosity at low temperatures
MEG, cheaper but harmful, cannot meet
sanitary obligations
Because change has already happened!
Change of attitude towards the environment
Need for solutions for the renewable energy
sector
Move from a "system“ approach to a
“systemic" approach

Follow the new way
Our commitment :
Offer alternative to solutions produced from
fossil resources and currently in use:
- Mono Propylene glycol
- Mono Ethylene glycol
Create environmental and long-lasting
consistency in industrial and commercial
installations
Bring you energy savings for refrigeration
and air-conditioning applications

7. 1. Greenway® Innovation
Follow the new way
• The Greenway® range consists of three heat transfer fluids
derived entirely from a renewable resource called BIO 1,3-
Propanediol (glucose syrup)
• Its production has an environmental benefit in terms of CO2
emissions and an energy footprint 40% lower than classic MPG
• Use Inhibitor pack developed by our R&D lab in order to offer
long term protection to the system and its materials.
• In case of an accidental leak, the impact on the environment
while using Greenway will be much lower than with an MEG

Stop Borax : Focus on regulation
The European Decree 2005/58/CE from the 15th
September 2008 puts Borax in the category 2
(toxic substances), and applies to all products
containing at least 8.5% Borax.
With BORAX ! Borax was put on the Substances of Very High Concern
list by the European Chemicals Agency in June 2010
Borax is toxic!
Presence of Borax in products has to be
mentioned of the related risks on the packaging:
R 60 : May impair fertility
R 61 : Risks of irrevocable damage to the child during pregnancy
S 45 : In case of accident or discomfort see a doctor immediately
S 53 : Avoid explosion, obtain special instructions before use

Long-term organic corrosion inhibitors
Traditional mineral-based inhibitors Traditional or mineral
inhibitors protect from
corrosion by forming a
heat transfer fluid protective layer on the
wall of the installation,
which can reduce heat
transfer
Reduced or
Protective disturbed thermal
layer exchange
Metal, pipe wall
Mineral inhibitors make physical deposits on sensitive areas
The silicates can form gels impacting on heat exchange

The General Direction of the Health and Safety Department Approval
The Climalife Greenway® BIO PDO
based heat transfer fluids have the
authorization of the French Health
and Safety Department for the
production of sanitary hot water via a
simple exchange
A ‘food safe’ approval for coolants, as
such, does not exist as Heat Transfer
Fluids are not used as food ingredients,
however:
Some have the approval of the French General
Direction of the Health and Safety Department as per
the opinion given by the AFSSA for use in single
exchangers or other approvals depending on the country
