7th Conference on Ammonia and CO2 Refrigeration Technologies

7th Conference on Ammonia and CO2 Refrigeration Technologies

The 7th conference on Ammonia and CO2 Refrigeration Technologies will focus on the intensifying global trend towards using natural refrigerants, such as ammonia, carbon dioxide and hydrocarbons in various refrigeration applications worldwide.

This year the conference will welcome RAC experts from ECA (Europe-Central Asia) countries in connection with the UNEP ozone network.

Dates: 11/05/2017 – 13/05/2017
City, Country: Ohrid, Macedonia
Address: Metropol Lake Resort, Hotel Metropol ****
