Rehlko, the former Kohler Energy, has reworked the lower end of its gaseous generator range. Six KG Series models, the KG80, KG100, KG125, KG150, KG180 and KG200, now come as one redesigned family, EPA-certified for 60 Hz applications in the United States and Canada, Rental Equipment Register reported on 9 October. The three smaller sets, 80 to 125 kW, run on a 6.2 litre Rehlko engine; the KG150, KG180 and KG200 cover 150 to 200 kW on a 10.3 litre Rehlko engine.
One Skid, One Enclosure Platform
Most of the changes are about how the sets go together on site. The fuel connects directly at the skid. The power box, the controller pedestal and the dual-fuel reset box are combined in a simpler skid layout, and the enclosures share a common platform with the rest of the Rehlko portfolio. Voltage, frequency, enclosure and controls are configurable, from single-unit control up to paralleling several generators.
Every set is tested at the factory for safety, electrical performance, durability, thermal balance, noise and vibration to ISO 8528-9 before it ships. Rehlko gives a two-year standard warranty, extendable to five years with a service contract through an authorised representative, and supports the range through its distributor network and its Performance Care 360 maintenance programme. The target markets are commercial, industrial and municipal standby: manufacturing, healthcare, water and wastewater treatment, telecommunications, hotels and retail.
Pat Crowe, Rehlko's product manager for the range under 600 kW, framed the update around confidence, both that the backup generator performs when needed and that it is easy to specify, install and support. A single family built on the same principles, the company argues, also makes training, maintenance and fleet management simpler for owners with several sites.
Small Sets, Same Questions
These are sets for the North American market, where standby on pipeline gas is common at this size: no fuel tank to maintain, no diesel to keep fresh. It is not the big-engine news of the data center plants, but the same practical points apply on a telecom shelter or a water works. A thermal balance test at the factory is worth asking about, because it shows how the set behaves at full load in its own enclosure, and the site then has to give it the air it was tested with. Installers know what happens when a set ends up against a wall or in a corner where its own warm air comes back to the inlet. The enclosure, the clearances and the ambient at the site decide that as much as the generator does, from the 80 kW set at a clinic to the multi-megawatt plants that make the headlines.
