The engines in Generac's new MDE330 and MDE570 are designed to prevent wet stacking by monitoring and regulating engine exhaust temperatures and providing supplemental heat, as needed.

Generac Mobile, a manufacturer of mobile light towers, generators, heaters, pumps and dust suppression solutions, has introduced two new large diesel units the MDE330 and MDE570 diesel mobile generators. The rental-ready machines feature wide-opening removable doors to maximize serviceability by allowing the technician to reach all service points. The steel design and construction allow for operation for a variety of applications, regardless of weather conditions.

The MDE330 features a 9.3L Perkins Tier 4 Final-certified engine, while the MDE570 utilizes an 18.1L Perkins Tier 4 Final-certified engine. Both engines offer standard Perkins Exhaust Temperature Management load management technology, eliminating the issue of wet stacking during low-and no-load conditions, which can occur if a diesel generator is improperly sized or oversized for the job. The engines in Generac's new MDE330 and MDE570 are designed to prevent wet stacking by monitoring and regulating engine exhaust temperatures and providing supplemental heat, as needed.

"Generac Mobile provides reliable power that goes where you need it, giving customers the versatility and control to get the job done – wherever that may be," said Aaron LaCroix, product manager, Generac Mobile. "Through advanced engineering and fuel-efficient designs, our units allow for extended runtimes and long service intervals so you can stay on the job longer, with less refueling and maintenance."

Generac's MDE330 and MDE570 come standard with a 500-hour oil and filter service interval for reduced maintenance and decreased downtime. Large capacity fuel and DEF tanks allow for a runtime of at least 25 hours before refueling is needed, increasing return on investment.

Optional features include increased motor starting capability, cold weather kits and additional power distribution options. For flexibility, these units can be configured for paralleling, enabling a scalable approach to power.

The Deep Sea Electronics 8610 MK11 controller comes standard on both units, allowing the user to monitor performance and perform diagnostics on the unit. The controller is conveniently located at the back of the machine about five feet, six inches off the ground on the trailered version for access. The Deep Sea Electronics 8610 MK11 controller puts all machine controls and information in one place, in a color touchscreen display that shows diagnostic codes and helpful information.

The new MDE570 is available for ordering now, while the MDE330 will be available for ordering and quoting in Q4 2022.
