Dynamic Packaged Applied Cooling has been in the forefront of promoting green initiatives and energy efficient products for several years – way ahead of our competition. We are proud to be members of ‘The Green Cooling Initiative’.
This initiative promotes the use of natural refrigerants, the development of energy efficient technologies and is fostering a sustainable approach to private and commercial energy consumption.
As a non-profit initiative, initiated by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, the Green Cooling Initiative offers a one of a kind platform for companies, organizations, countries and individuals. Aiming at a reduction of emissions from the cooling sectors, Green Cooling combines three approaches:
- Promoting natural refrigerants
- Maximizing energy efficiency
- Fostering a sustainable approach to private and commercial energy consumption.
Green cooling technologies help to protect the environment, resources and the climate. The aim of the Green Cooling Initiative is to establish a global Green Cooling Network, which will accelerate the transfer of environmentally friendly technologies in the refrigeration and air conditioning sectors and support the use of renewable cooling technologies. Thereby, the Initiative aims to contribute towards a sustainable reduction of fossil fuel consumption and greenhouse gas emissions.
For those of us involved in Commercial HVAC equipment supply, then we of course are all too aware, and there are plenty of Manufacturers now offering alternatives to the conventional HFC’s, ourselves included!
However, the current main (non HFC) alternatives for the larger Buildings/Applications are using either Ammonia, CO2 or Propane and they all have different considerations when it comes to selecting these as suitable alternatives to a buildings Commercial cooling system.
Ammonia is highly toxic; it is well suited to large industrial systems, but less cost effective at small and medium sizes. HC’s are highly flammable; they are excellent refrigerants for very small hermetically sealed systems but safety used to be an issue for medium and large sizes – although that has now changed somewhat.
For the purpose of this article we are considering the use of R290 (Propane) and its suitability, as well as ensuring safety considerations and precautions are taken into account, as after all this is a Flammable gas!
Propane has been used and selected in hundreds of projects for many years and the GWP vs HFC’s is well documented and is currently the preferred alternative for large and small A/C replacement projects.
For larger commercial and industrial buildings, equipment is available with duties up to 1,000Kw in single packaged Air Cooled units, which can be mounted externally However, when considering replacing water cooled Chillers that are installed inside a building then adequate safety systems have to be considered, (just like Commercial Gas Boilers)
However, getting and transporting Propane for servicing is not that easy and fully licensed suppliers are the best alternative, rather than trying to get a service engineer to transport it!
The applications for equipment using R290 (propane) as a Natural Refrigerant are widespread, covering Comfort Cooling, Process Cooling, Close Control (Data Centre) and General Refrigeration (Food Storage)
With Natural refrigerants and innovative technologies DPAC UK has developed an innovative product/technology for the green cooling sector. As a member DPAC UK supports the Green Cooling Initiative in its efforts to promote natural refrigerants, innovative technological products and protect the environment, resources and the climate.

UK based M&E Consultants, Contractors and FM Businesses should now be considering Natural Refrigerants as an alternative (particularly if they are involved with replacing older large packaged air cooled units) and in most cases they are far more cost effective, being more efficient and with lower running costs.
