Caterpillar System Receives Certification
Parts kit for landing drilling applications now CARB certified
Caterpillar Global Petroleum announced that its Dynamic Gas Blending (DGB) System for Cat 3512C land drilling applications has received off-road aftermarket parts certification from the California Air Resources Board (CARB).
Cat said its DGB system is certified for use with fuels with a lower heating value (LHV) of between 905 BTU/scf to 1250 BTU/scf, giving operators a wide range of fuel options while meeting Tier 2 emissions levels.
The DGB kit automatically adjusts to changes in incoming fuel quality and pressure, allowing engines to run on a wide variety of fuels – from associated gas to vaporized LNG – with no loss of performance integrity, the company said.
Cat said its DGB maintains diesel performance levels with up to 70% replacement of diesel with gas, accepts up to 55% inerts, and can be applied to existing engines with EPA certification or exemption. According to Cat, no customer input or gas analysis is needed during operation, and no recalibration is required when the equipment is moved or the gas supply changes.
Caterpillar will offer both a CARB certified kit as well as a non-certified kit for non-regulated areas.
