Day three focused on R-410A technology since it is fast becoming the dominant technology because of greater energy efficiencies with some models. This component of the workshop was conducted by Mr. Badasee Nanan – RSES CM from Trinidad and Tobago. Some the topics covered included, propoerties of R-410A refrigerant, Safety, Pressure Temperature relationship , recovering R410A refrigerants, instalation and maintenance differences.

Participants also visited the T A Marryshw Community College (TAMCC), the leading technical institution in Grenada to observe the classroom environment and to interact with the lecturer since several participants are RAC instructors in their own countries.

Day three concluded with an evaluation and closing ceremony, Permanent Secretary, in the Ministry of Finance where the National Ozone Unit is located delivered the feature address.  Also addressing the participants were Mr. Marco Pinzon from UNEP ROLAC and Mr Henry Frederick of GRAVA.  Participants were presented with certificates of participation for both the Hydrocarbons and R-410A components.  This brought closure to an extremely successful three days of training in alternative refrigerant technologies.
