Natural refrigerants

Over the last few years, the use of natural refrigerants has shown an enormous increase. The two main reasons for this are:

  • Under certain operating conditions these refrigerants are energetically more efficient than synthetic refrigerants.
  • Governments worldwide are planning to ban as many synthetic refrigerants as possible. They will do this by considerably raising the cost of synthetic refrigerants and/or by forbidding the use of certain synthetic refrigerants.

We have a lot of experience with the natural refrigerants ammonia (NH3) and carbon dioxide (CO2).

Years ago, Bort de Graaf Refrigeration Technology was one the first refrigeration installers in the Netherlands to anticipate to this new development in refrigeration technology: the use of natural refrigerants. In 2001, Bort de Graaf Refrigeration Technology, installed the first flow-freezer working on CO2 in Europe.

This freezing tunnel is still being used on a daily basis, freezing eight tonnes of shrimps per hour. Since then, we have completed many projects using natural refrigerants. From large meat and fish processing plants, to the first two supermarkets in the Netherlands that used only natural refrigerants (NH3 and CO2).
