DUAL POWER STATIC ST28.115

DUAL POWER STATIC GPU EFFETI ST28.115

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.

Quality and certification

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
