Benefits of Preventive Inspection & Maintenance Services



1- Failure prevention: Regular inspections and diagnoses by specialist engineers will not overlook small changes in equipment conditions. Problems such as lost opportunities due to door failures can also be avoided.


2- Maintenance of comfort: The performance of the automatic door device that repeats opening and closing each time a passer passes is continually deteriorating. By carrying out periodic inspection and maintenance, it is possible to maintain a comfortable state at the beginning of installation for a long time.


3- Extension of service life: Periodic inspection and maintenance and appropriate preventive maintenance prevent sudden failures, prevent equipment performance degradation, and slow down the overall deterioration rate of the equipment.


4- Ensuring safety: In addition to daily inspections, regular inspections and maintenance by specialists will ensure that you can always use the automatic door safely and securely.


5- Reduction of running costs: By carrying out regular inspection and maintenance, sudden expenses can be avoided. Carrying out appropriate repairs in a timely manner extends the life of the equipment and does not lead to major repairs, resulting in a reduction in total costs.
