VTech's refrigerant charging equipment are designed with the end-user in mind. Please refer to the following link for for some general guidelines about each end-user market: 

Refrigerant Charging Equipment by market  

Another variable impacting the design of today's refrigerant charging systems is the introduction of Hydrocarbon refrigerants, which are flammable in nature. Charging equipment therefore must incorporate safety systems in accordance with current regulations. Please refer to the following link for an overview of VTech's equipment offerings for flammable vs. non-flammable refrigerants:

Refrigerant Charging Equipment - flammable vs. non-flammable

VTech's refrigerant charging boards can be supplied as standalone units or as part of turnkey projects, with leak testing, pre-evacuation and electrical safety and performance test equipment. For specific Commercial Refrigeration applications, VTech has developed equipment combining pre-evacuation, leak testing and refrigerant charging combined in one single unit.

Each project is completed with on-site installation and training.
