Package
In accordance with GOST 949, 227ea can be packed in 50 dm3 cylinders designed for operating pressure not less than 2.0 MPa or 227ea can be packed in 1000 dm3 containers (drums) designed for operating excessive pressure not less than 2.0 MPa. So each 1 dm3 of the vessel should be filled with1.1 kg of the liquid refrigerant at the most.

Transportation
227ea can be transported by railway or by automobile transport.

Storage
227ea must be kept in a storage room at temperatures not exceeding 50°С far from heaters on an open place protected from direct sun. Guaranteed shelf life is 3 years from the date of manufacture.
