Comec VPT 130 - Cylinder Head Pressure Tester

VPT 130 is a water tank pressure tester which allows, with precision and ease, detection of possible cracks and leakage of cylinder heads and blocks by immersion in hot water. The tank, complete with its cover, is manufactured of stainless steel and perfectly insulated to avoid heating dispersion and is filled with water which is heated by two powerful heating elements which operate independently and are controlled by an automatic timer which includes heating programs to optimixe and reduce electric consumptions.
The cylinder head is clamped, by using the standard equipment included with the machine, on the cradle which is actuated by an over dimensioned hydraulic unit that moves, quickly and without effort, cylinder heads and blocks particularly heavy and furthermore revolves of 360¾ thanks to a motoreducer; that allows a whole visibility of the head, even if when totally submerged, for an easy and prompt detection of leakage.
