FOLLOWING SOME PHOTOGRAPHIC EXAMPLES OF MAINTENANCE USUALLY CARRIED OUT

aircraft sleeves

Complete maintenance of sleeves for the coupling of aircraft to the terminal. We provide preventive, corrective and corrective emergency maintenance services: The airport does not rest.

LIFTS (HYDRAULIC AND MECHANICAL) and escalators

Maintenance of mechanical and hydraulic equipment, for passengers or forklifts.

centrifugal pumps

Maintenance of pumps for the impulsion of drinking water, industrial, sewage and other fluids.

boilers

Maintenance of hot water boilers and steam generators for HVAC and industrial use.

: Maintenance of screw chiller, with R134 refrigerant of 300TR capacity. As part of the preventive maintenance system, an annual oil level and condition check is performed.

En la figura se observa el visor que marca el nivel de aceite por encima del nivel mínimo de 50mm en el carter.

generator sets

Maintenance of generator sets

ups

UPS maintenance "Uninterruptible Power Supply"; They are the ones that avoid the interruption of computer systems due to cuts in the public electricity network. We have designed and installed a wide range of equipment that we maintain today, in powers between 10 and 200kVA.

: Annual maintenance (and annual change if necessary) of internal fans.

: Maintenance and periodic verification

: Corrective maintenance with original spare parts from the manufacturer, with whom we have agreements in many cases.

: Maintenance and periodic verification

: Periodic control of the operation, warnings and alarms indicated by the equipment, to act quickly in the event of an anomaly.

: Periodic control of the operation, warnings and alarms indicated by the equipment, to act quickly in the event of an anomaly.

: Provision and installation of UPSs. In this case, two combined units of 200kVA each for the service of the data systems of the airport terminal.

: The service includes the periodic verification of batteries and their replacement when they have reached the end of their useful life.

: Mantenimiento anual (y cambio anual en caso de ser necesario) de ventiladores internos.

: Mantenimiento y verificación periódica

: Mantenimiento correctivo con repuestos originales del fabricante, con quienes en muchos casos tenemos convenios.

: Mantenimiento y verificación periódica

: Control periódico del funcionamiento, advertencias y alarmas que indica el equipo, para actuar rápidamente ante caso de anomalía.
