Refrigerant Charging Systems for Commercial/Domestic Refrigeration and Air Conditioning

VTech's refrigerant charging systems are designed to meet the highest standards for speed and accuracy while providing a user-friendly interface and a large selection of optional features. We analyze each project based on the end user's requirements and provide our expertise to optimize process and equipment application.

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

VTech's equipment range for flammable refrigerants include single or multiple refrigerant charging systems, even combining Hydrocarbon, HCFC and HFO refrigerants. We initially act as project consultants on the safety aspects of the project according to European ATEX or NEC Class 1, Div. 2. In addition to the refrigerant charging board we can supply a turnkey installation with all the safety equipment, including custom-designed safety enclosures, in accordance with the applicable safety standards.

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