Rating definit ions Baseload power Unlimited hours usage with an average load factor of 100% of the published baseload power rating.

Prime Power Variable load. Unlimited hours usage with an average load factor of 80% of the published prime p ower rating over each 24 hr. period A 10% overload is available for 1 hour in every 12 hour of operation.

Standby power Variable load. Limited to 500 hours annual usage up to 300 hours of which may be c ontinuous running. No overload is permitted.

Emissions capability All 4012-46TWG ratings are optimised to the ‘best fuel consumption’ and do not comply to Harmonised International Regulation Emission Limits. More information on these statements can be obtained by contacting the Applications Department at Perkins Engines Company Limited.

Coolant pump

Recommended coolant: 50% inhibited ethylene glycol or 50% inhibited propylene glycol and 50% clean fresh water. For CHP systems and where there is no likelihood of ambient temperature below 10 °C, then clean ‘soft’ water may be used, treated with 1% by volume of Perkins inhibitor in the cooling system.
