JCB launches Stage V rental genset

14 April 2021

Key features of the new genset, the G40RS V, include electronically-controlled JCB by a Kohler engine and combined DPF and DOC with no requirement for SCR.

It also produces 87% less NOx and 96% lower PM per kW/h, while single-side service access enables ease of maintenance.

JCB’s G40RS V genset replaces the Stage IIIA G36RS model.

JCB describes the genset as easily transportable and “designed to work in the harshest rental environments.”

“Built on an over-gauge base frame, with a 2mm thick Galvtec steel canopy, the G40RS V has a 40mm fixed single point lift point, four base frame lifting points and integrated fork pockets, for rapid deployment to site.”

“The integrated fully bunded fuel tank has ADR compliance, for safe road transport, and the canopy has vertical hot air discharge vents, to reduce noise and prevent dust swirl around the set on site.”

The G40RS V genset replaces the Stage IIIA G36RS model, delivering 40kVA at 50Hz frequency.

It is powered by a JCB by Kohler KDI 2504 TCR four-cylinder turbocharged engine, developing 42.4kW (57hp).

This uses a single-can Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF), mounted in front of the radiator to retain slim canopy dimensions.

The DOC is maintenance-free and the DPF is regularly cleaned using regeneration, designed to maintain optimal machine operation, even at low loads and temperatures, maximising uptime for the customer.

Other features include large, lockable doors with access to all service points, with routine service intervals set at 500 hours.

Replaceable filters are located on the cold side of the engine, while a lift-off panel provides access to the cooling pack, loadbank elements and the DOC/DPF canister. There is no requirement for SCR or Diesel Exhaust Fluid (AdBlue).

The G40RS V can be supplied with DSE7310 or DSE8610 (synch) controllers, the latter allowing the G40RS V to be easily connected to other machines.

A four-pole Schneider circuit breaker is standard and there is an emergency stop button mounted on the canopy, next to the control section.

JCB LiveLink telematics provide remote monitoring, while the ADR-compliant fuel tank provides a minimum of 24 hours operating autonomy and the lifting points have been designed to allow fully-fuelled delivery.
