TESTION, a.s. expands its equipment with a new hydraulic unit for cyclic pressure tests. The Bosch Rexroth equipment enables controlled hydraulic cycling in the range of 2 to 100 bar, with a pressure rise rate of 0.2 ÷ 200 bar/s, the possibility of entering a pressure profile (e.g. sine, trapezoid, etc.). PC control of the cycling process and its recording is also included. This equipment will expand the existing equipment especially for testing of coolers, heat exchangers, evaporators and other pressure vessels and equipment.
