Breaker Technology Explained
Inside every Montabert breaker, an automatic pressure regulator reduces pressure variations, preventing overheating, and extending the life of the breaker. In addition, Tramac by Montabert breakers never lose power and productivity like nitrogen-assisted breakers.
Most nitrogen-assisted breakers' energy comes from compressed nitrogen. During use, hydraulic flow displaces the piston upward, compressing the nitrogen. At the top of the stroke, hydraulic flow stops or is diverted, causing a shock to the carrier's hydraulic system. The built-up pressure in the nitrogen chamber pushes the piston downward. However, as nitrogen leaks with use and improper storage, power decreases, until the breaker is refilled.
In contrast, Montabert breakers use hydraulic flow to move the piston up and down. On the up stroke, excess oil is stored in a fully enclosed energy chamber. Once the piston reaches the top of its stroke, high-pressure hydraulic flow is diverted, and forces the piston downward. Towards the end of the stroke, stored oil from the energy chamber is released to complement flow from the carrier and to compensate for the piston's high velocity. Then the cycle repeats for constant power and performance with every blow.
