All NRP recovery cylinders meet ARI guidelines and DOT specifications.
It is very important to evacuate the recovery cylinders and purge the hoses to avoid introducing non-condensables in cylinders which would increase the discharge pressure. Also, a separate cylinder must be used for each type of refrigerant to avoid cross contamination.
Caution: for safety reasons it is very important to fill all cylinders by weight in accordance with the cylinder supplier’s instructions and ARI guidelines.
