Only Fluorocarbon refrigerants from refrigeration and air conditioning
systems are acceptable. Halons will not be accepted. Fluorocarbons
from other applications such as solvents or cleaning agents are
NOT acceptable.
Non-fluorocarbon refrigerants such as ammonia, methylene chloride,
propane, ethane, sulfur dioxide, etc., are NOT acceptable. Also,
fluorocarbon refrigerants contaminated with hydrocarbons in excess
of 0.5% by weight (total hydrocarbons) will not be accepted.
Only one grade of refrigerant per container is acceptable. Refrigerant
must be shipped in DOT approved recovery containers. Refer to ARI
Guideline K.
Containers must not exceed the Maximum Allowable Gross weight
as specified in NRI's Cylinder Weight Chart. Overfilled containers
will be subject to a handling fee.
Refrigerant contaminants are acceptable with the following limits:
PURITY
99.5 % for R502 minimum (excluding oil content) 99% for all other
CFCs, HCFCs and HFCs
COMPONENT RATIOS
Must be within ARI 700 specifications for any refrigerant containing
two or more components
OIL
Not to exceed 20% by weight in R11, R113 & R123 Not to exceed
10% by weight in all other refrigerants
WATER
Water exceeding saturation point of refrigerant requires special
processing to separate the free standing water from the refrigerant;
fee will be charged for each pound of free water
ACID
pH must be greater than 2.0 and less than 12.0; pH level between
2.0 - 5.0 requires special handling to neutralize acid in the
material; fee will be based on the gross weight of material
DYES
Not to exceed 1 % by weight
