Pre-evacuation is one of the most important steps in the manufacturing process. Ensuring that circuits are free from moisture and other contaminants is essential in ensuring product quality. VTech offers both single and multiple pump configurations with different levels of automation, from the Pre-Vac 10 Manual Evacuation System to the VTech 40 Automatic Evacuation System with Vacuum Decay Leak Test. VTech also offers its Data-Vac System for plantwide integration of pre-evacuation systems with wireless data transfer capability including RF vacuum gauges, wireless hub and PC software.

VTech offers a comprehensive range of electrical safety and performance test equipment meeting the needs of appliance, commercial and residential equipment manufacturers.

Electrical Safety Test
For Electrical Safety Testing, VTech’s product range includes the VTech ST Series integrated system for multiple tests as well as the VTech EL Series test modules suitable to perform single independent tests. These tests include:

• Earth Continuity (Ground Bond)
• Insulation Resistance
• Dielectric Strength (Hi-Pot)
• Earth leakage current 
• Power Consumption

Refrigerant Cylinder Filling requires high-speed automatic charging of multiple refrigerants from bulk tanks to smaller cylinders for distribution. Virtually any refrigerant gas can be handled.

The VTech TRP Series High Vacuum Pumps have been designed to meet the needs of industrial users for non-corrosive environment applications such as Air Conditioning and Refrigeration manufacturing. They are utilized for both pre-evacuation carousels as well as integrated into VTech leak testing and refrigerant charging equipment.

The TRP Series Two-Stage Pumps deliver excellent ultimate vacuum, high pumping speeds, quiet and cool operation and easy maintenance. Durability and product support are additional highlights of these pumps. Enhanced features not available on service-style pumps include an anti-suckback device, continuous duty cycle rating and low ultimate pressure.
