Cummins home generator family business thrives in the hills of North Carolina

Allan Dearth Generators and Sons is a generator dealer based out of Scaly Mountain, North Carolina (USA) that is giving “family business” a whole new meaning.

Owner and operator Allan Dearth has been doing electrical work for many years and even in the early stages was familiar with Cummins’ product. But it wasn’t until his eldest son decided to move home and dive into business with him that their family-owned operation came to life. Since its founding 14 years ago, their business has been a constant trend of positive success with a supportive Cummins network in their back pocket. 

Many years ago, Allan worked for an electrical company that was his first introduction to the market. He spent seven years delivering, setting, wiring and installing Cummins home generators and eventually took an opportunity to lead a Cummins account where he learned to service products as well. He maintained this role until he received an exciting call from his son, Bryan Dearth.

At the time, Bryan was working in Milwaukee as a diesel mechanic. He told his father that he was coming back home, and he wanted to start their own generator business. Fourteen years ago, this was the conversation that ignited their operation: Allan Dearth Generators and Sons (ADS). Now their business includes ten employees, six of which are family by blood – the other four considered honorary family members by association.

ADS has been selling and servicing Cummins home generators since their inception. They provide service to three different states (North Carolina, South Carolina and Georgia) as they are conveniently located near the tri-state border. In the early days, their local area was a very seasonal town. During the winters they would have a population of 4,000 that would grow to nearly 30,000 with tourists during the summers. Now it is more of a year-round town and ADS regularly services about 1,500 generators. 

Over the years, the Dearth family has had great experiences with Cummins’ products and service support. Allan said, “Cummins has always been a good generator, they have a good price point, they are reliable and we like working on them because they’re simpler than most brands.”

Allan highlighted a unique experience with a customer who was doubling the size of his home. He had put a Cummins generator on this man’s residence over 20 years ago and subsequently supported the request to install a larger unit to accommodate his increased power need. The customer no longer had use for the old generator, so he donated it back to ADS. 

Allan took the unit, serviced it and was able to resell it to a gentleman who is a general contractor working in a remote area with zero centralized power. The man was building seven houses on a piece of property over the course of eight months and needed a dependable power solution during the construction period. ADS installed the 22-year-old generator for him and he now runs it eight hours a day, six days a week. Their team services the unit every three weeks and it still runs like new.

In summation, Allan offered up some advice for anyone on the market for a home generator, “Service support is a big factor. People want to know if they run into a problem, who is going to back them up? It’s all about the support behind the product.” With confidence, he said, “We’re here and we’re here to stay. And Cummins will always back us up.”

Cummins Custompaks are being used for water management as Thailand struggles with its water crisis

Water crisis

Sixty Cummins Inc. CustomPaks are in service in Thailand as part of a critical water management plan aimed at easing the country’s water crisis – a crisis that has caused enormous economic and social damage and stirred conflict among communities.

Over the past several decades, Thailand has continually faced water problems caused by severe drought. Water reserves in dams and reservoirs are insufficient while water resources are often contaminated with toxins caused by urban communities and the industrial and agricultural sectors.

Severe flooding is a threat, too, at a time when the realities of climate change are hanging over the country.

As a result, the allocation of precious water resources, which must be shared among various stakeholders including new and existing industry, large and small agriculture, and cities and villages has become a flashpoint.

Kittithanapat Engineering Co. (KTP), has been involved in the water management system since 1996, working closely with authorities such as the Royal Irrigation Department, Department of Water Resources, Bangkok Metropolitan Authority and others.

600 hp CustomPaks

To help KTP meet its often urgent requirements, Cummins DKSH (Thailand) has recently supplied 60 Australian-built CustomPaks – 45 powered by Cummins’ X15 engine rated at 600 hp, and 15 powered by the QSL9 rated at 325 hp. These fully self-contained powerpacks are emissions certified to Tier 3.

The CustomPaks are coupled to hydraulically-driven, large-volume submersible water pumps sourced by KTP from US company Moving Water Industries (MWI); KTP is the exclusive distributor in Thailand for these MWI Hydroflo pumps.

Prior to Cummins’ involvement, KTP was using another diesel engine brand but service support wasn’t up to the standard required.

Long-serving KTP engineer Kittisak Thanasoot says Cummins DKSH’s reputation for technical and aftersales support along with the reliability of the Cummins product were a key reason behind KTP’s decision to specify the CustomPaks for the Royal Irrigation Department.

The ability of Cummins DKSH to respond to short delivery times was also important.

“Supplying large quantities of high horsepower diesel engines for emergency situations such as flash flooding can be a challenge for KTP,” says Kittisak Thanasoot.

“Responding to the needs of the government agencies to manage such problems in a timely manner and with least impact on communities, KTP has found the answer in our partnership with Cummins DKSH.”

Power, pride and passion

The switch back to Cummins power has been beneficial for iconic New Zealand company Uhlenberg Haulage. It's all about whole-of-life costs.

Uhlenberg Haulage is closing in on 60 years in business, having been founded in 1966 by Mike and Carol Uhlenberg.

Based in Eltham, Taranaki, in New Zealand’s North Island, the operation is today owned and operated by their sons Chris, Daryl and Tony Uhlenberg.

Describing the Uhlenbergs as “old school family truckies”, Daryl talks about the company’s time-honored journey with a definite tone of pride, especially the work of his parents in laying the foundations for what is today an iconic fleet in its own right.

Cummins Inc. made its debut in the Uhlenberg fleet in 1971 with an NH250 powering a second-hand Kenworth K923 used in logging. A second Kenworth, a new W924 with a Cummins NTC335, followed soon after hauling an LPG tanker.

The Uhlenberg operation today comprises 40 prime movers and a variety of trailing gear to cater for the myriad of a jobs the fleet is involved in.

A number of Peterbilts feature in the fleet although Kenworth is now the brand of choice with six new units to be delivered over the next 12 months to cater for business growth.

Cummins’ X15 Euro 5 engine rated at 550 or 600 hp is the preferred power specification, with 18 red engines currently in the fleet.

Whole-of-life support

“The switch to Cummins has been a very good experience for us. We have nothing but praise for the Cummins organization,” says Daryl.

“The whole-of-life picture is the key thing for us and we’ve got that nailed with the support we get from Cummins – parts availability, scheduled maintenance, life expectancy and in-frame rebuilds.

“So the red engines turn up, we run them to life, which is 900,000 to 1.2 million kilometers, and then Cummins does an in-frame overhaul in a timely manner. If there’s an issue, parts and support are close by.

“The support we get from Cummins Palmerston North is fantastic, second to none.”

Daryl recently looked under a Kenworth that was in the workshop for a service and was surprised to see no oil leaking from the one-million-kilometer X15. “I remember when I was a fitter we had to wear a raincoat when working under a truck,” he jokes.

Fuel agnostic

Acknowledging that the push to decarbonize is now “very real”, Daryl likes the idea of Cummins’ fuel agnostic concept where one base internal combustion engine, optimized to run on diesel, can also be customized to run on ultra-low and zero-carbon fuels like renewable natural gas and hydrogen.

“My father was a pioneer of linehaul trucking in New Zealand and he always embraced new technology. He was never scared of it,” he says.

“I tend to be a little more cautious but I can see where a 500 hp natural gas or hydrogen engine would work for us in short haul applications,” he admits. “We’re certainly willing to look closely at these alternative fuel technologies when suitable infrastructure is in place.”
