For as long as there has been recovery and recycling, there has been reclamation. But reclamation is a bit of a different animal.
Recovery and recycling of refrigerant takes place on site with equipment toted to the site by the service technician. Reclamation typically involves refrigerant recovery and shipment to a reclaim facility. Reclamation can be more time-consuming, but it provides the best assurance that a reintroduced refrigerant is of the highest quality.
