Teklab solutions for CO2 refrigeration systems

CO2 as a refrigerant ( R744 ).

The use of CO2 as refrigerant is gaining popularity due to its low environmental impact.
With zero ozone depletion potential (ODP = 0) and a Global Warming Potential (GWP) of only 1, the use of CO2 in refrigeration systems can lead to decreased direct emissions of ozone depleting substances (ODS). Also the odorless and colorless CO2 is non-flammable .
His thermodynamic properties make it suitable for a wide range of applications in commercial refrigeration and air conditioning

The use of CO2 as refrigerant has advanced considerably in recent years and major supermarket chains are currently using CO2 systems in preference to HFC systems wherever feasible. In Europe and elsewhere the use of CO2 refrigeration systems is increasing steadily.

is involved in this evolution from many years and offers solutions for the level managing in R744 high pressure and extreme temperature cooling systems.

Teklab devices are designed for use in level monitoring applications for the control of oil or liquid CO2 for transcritical or subcritical systems.

The main features to highlight for R744 application of TEKLAB products are:
  • Teklab optical level switches have no mechanical moving parts, thus particularly suitable for high reliability level monitoring
  • Possibility to combine the Temperature Management with Level switch in one unit
  • High pressure resistance up to 120 Bar
  • High temperature resistance up to 125 °C
  • Well consolidated steel with fused glass technology ensures no leakage and good chemical compatibility with CO2 and the different kinds of oil used.
  • Many installations worldwide of products in transcritical or subcritical applications.
