So why not use a conventional refrigeration system? There are many different types of refrigeration technologies present in today's market place. These vary from absorption chilling and compressors to air-cooled systems.
However, to achieve high flow rates of water at low temperatures the 'conventional' refrigeration methods are not usually economically viable.
Conventional refrigeration needs compressors and coolants to enable the process to work. These systems require much energy and regular maintenance. They are costly to run and in some cases contribute to greenhouse gas emissions themselves, (with the use of ammonia or lithium bromide).
WF is a form of 'jet refrigeration' and does not require coolants or compressors to produce large volumes of chilled water.
WF only needs the input of low pressure waste steam and process water to operate.
Using the steam as a fuel a combination of venturi ejectors create a vacuum in specially designed condensers and evaporators. This process effectively chills the water to the desired temperature required.
