Abstract
The invention features a method and device for introducing fluid material into a climate control system. The fluid material can include a lubricant or a leak detection additive. The device includes a housing having an exit orifice and a housing holder having a trigger. Multiple doses of fluid material can be delivered to systems using the same housing. The method and device can allow a user to provide more economical, faster and cleaner service than with smaller volume systems, because, for example, less time is used to change the housing, eliminating or reducing contact with the fluid material and contamination of the work environment with the fluid material. The housing holder is compact and lightweight due to the absence of an external support structure holding the housing.
