DUAL POWER STATIC GPU (Ground Power Units) EFFETI designs and manufactures STATIC GPU (Ground Power Units) systems that can convert electrical power supplied by the normal distribution network into energy available to operate the on-board systems of aircrafts without the need for diesel engines. The advantages to this type of application can be summarized as:
Zero contaminant emissions
Ability to work both outside and inside the Hangar
Practically no noise input
Savings on the machine operating cost
Savings on maintenance (given the absence of the diesel engine)
Reduction in defects and increased profit for the system life (no rotating parts)
With the ST28.115 DUAL POWER STATIC GPU (Ground Power Units) it is possible to supply aircraft operating both in direct current and in alternate current, both individually and simultaneously.
The operation management and electrical measurements (current, voltage, etc.) of the ST28.115 DUAL POWER STATIC GPU (Ground Power Units) are readily monitored through high precision LCD devices with TOUCH SCREEN technology fitted in a clearly visible position and easily accessible to the operator.
The trailer with steer and swivel front wheel translates to extreme ease of transport while the fully opening steel sheet hood provides strength and complete access to all electrical components installed inside the system.

For EFFETI customers the importance of service quality weights, when choosing our products, as much as the price of the product itself. For this reason over the years EFFETI has set up differentiated after-sales service support with two types of assistance: 1. STANDARD: ordinary maintenance package for the years following the purchase. 2. EMERGENCY: fast response, with intervention at the customer's site.
Effeti designs and manufactures customized power solutions in the form of power generators for the most important Italian companies in the railway, marine and aviation industries.
In addition to the well-established production of power generators for the most important Italian companies, the EFFETI team takes care of the scheduled or emergency maintenance of all machinery used by its customers.
Effeti has been ISO 9001 certified since 1998.
The company has always ensured consistent quality levels in its products. When an act was passed in 1995 requiring all suppliers to state agencies to obtain the ISO 9001 certification, EFFETI had its existing standards approved within a short time: procedures, testing, audits in the production line were consolidated business practices even before certification was required by law
