Notes

The prefill nitrogen gas pressure measured statically (breaker not operating) without down load on the tool at the stabilized gas temperature of +20 °C.
The recommended value at the normal operating condition (supplied oil flow, oil temperature and viscosity, etc.).
The value which is set at the factory to obtain the nominal operating pressure at the middle value of oil flow and back-head gas pressure.
The maximum allowed oil pressure at the breaker’s connection point to the return line (measured statically without the breaker).
The allowed temperature limits when using the oil of viscosity grade 46.

Available Tools (CHISELS)

Notes

The diameter of the tool portion outside the breaker body.
Other special designs are also available on request.
