Warranty Policy

Components (individual and assembled) and processes are subject to a comprehensive guarantee to which end HERS undertakes the rectification of faulty workmanship and manufacture, at no additional cost.

New and repaired cylinders are covered by a 12-month warranty or 3000 hours, whichever occurs first.

Overhauls on transmissions, gearboxes and differentials carry a 1000 hours or 6 months from date of delivery, which ever comes first.


Contamination is a large contributor to cylinder failures and HERS will not be held liable for any failures related to contaminated systems.

Warranty Terms & Conditions
