The vacuum box could be used for checking:

• reservoirs,
• boilers,
• pipelines,
• fuel tanks,
• coating,
• other objects with one-sided access.

• Patented in-house design for convenient control and low energy consumption of the testing operator.
• Specially designed molded rubber strip makes the contact with the inspected surface more leak-tight. It helps to reach the ultimate degree of exhaustion within the box:-0,09 MPa, which exceeds PNAE G-7-008-89 and PNAE G-7-019-89 standards for IV class leak - tightness (Rules and Norms of Nuclear Power Generation Industry) 
• Operational tests showed that the leak-tightness in the vacuum box is kept for a long time (pressure decrease to -0,08 MPa during 20 min).

• flat vacuum box with a vacuum gauge and handles;
• ticket (with a manual);
