Portable self-contained ground power units, (GPUs), from Powervamp “have transformed the versatility” of Florida-based Boca Aircraft Maintenance (BAM), according to co-founder David Hintzke.
Boca Aircraft Maintenance provides general aviation service and support for a wide range of corporate and business jets from makers such as Falcon, Learjet, Challenger, Eclipse, Gulfstream and Hawker. They are based at Boca Raton, fifty miles north of Miami.
Powervamp is a world leader in aviation ground power units. Its product range extends from hand-portable DC aircraft start units to heavy duty ‘Coolspool’ battery-carts as well as its diesel-driven hybrid models. Powervamp also designs and manufactures its own range of mains-powered aviation 400Hz frequency converters.
Boca Aircraft Maintenance currently use half a dozen different GPUs from the Powervamp ground power range including the PS300 DC power supply, Coolspool 29 and Coolspool 260 DC battery cart.
The engine start units used by Boca Aircraft Maintenance can provide power for a variety of aircraft types, including larger twin-turbine aircraft. The trolley mounted Coolspool 260 is capable of starting all medium sized jet aircraft and is the largest Powervamp unit used to date.
Some Powervamp units are also designed to power on-board electrics and avionics suites whilst the aircraft are on the ground. The power supply models are designed to provide a constant ‘clean’ 28V DC for as long as the aircraft requires the power.
When Boca Aircraft Maintenance was founded in 2009, the company used much larger and more conventional diesel-driven ground power units. “It was a buyers’ market,” David Hintzke says, “so that approach suited us at the time.
“But the old units were unwieldy, and only lived in the hangar. The Powervamp units are so compact and portable in comparison that we can quickly move them wherever they are required.”
That flexibility extends to work undertaken at external sites. The company’s technicians simply load a Powervamp unit into a service van and take it with them to the customer’s premises. “We look on the Coolspool 29 as a ‘jump box’,” David says. “It’s no bigger than a suitcase, yet it can start an aircraft engine from its own internal battery.
On some occasions we might connect a lightweight PS100 to a local power outlet to provide DC power whilst we perform software upgrades. The versatility of the product range helps us with AOG (aircraft on ground) situations”
There are other benefits to the Powervamp range besides its portability, David says. “They’re reliable, they’re weatherproof, and because they are battery or electrically powered they’re clean and cause no noise pollution.”
Boca Aircraft Maintenance isn’t just impressed with the Powervamp product range; David is also enthusiastic about the company’s sales and service performance. “It’s top notch,” he says. “Powervamp USA is itself located in Boca Raton, so we have become an invaluable resource for gathering in-service experience with Powervamp products.”
So keen is Boca Aircraft on the Powervamp range that it has even found itself in the position of a reseller, supplying a number of Powervamp ground power units directly to customers. This applies particularly to the Coolspool 17 unit, which is supplied with a 26V DC output specifically designed for the Eclipse 500 / 550 series aircraft. Boca Aircraft is an Eclipse approved service centre, supporting aircraft from all over the world.
As Boca Aircraft continues to grow, the company expects to expand its presence in nearby Miami. As and when that happens, the company will be adding further Powervamp units for use there. “We’re big Powervamp fans,” David Hintzke says “and look forward to working closely with the company for many years to come”.
