Retrofit renovation and partial renovation

  • Interchangeability of electrical functions and performance is secured. At the same time, structural interchangeability is also secured while replaceable parts are updated.
  • It is devised to reduce field fabrication work as much as possible so that the renovation period can be reduced to the shortest amount of time.
  • Where replacement parts are unavailable, such parts will be designed and manufactured.

Printer for the monitoring system

Some monitoring systems installed in plants are still using dot impact type printers. They are now difficult to repair and maintain.
We have created a new renovation method by which output information to the printer is saved in a personal computer (PC) so that the data can be monitored on the PC screen and hard copies are printed out on the updated laser printer as required. A single PC can control up to two printers. Such a method is immediately helpful for space saving, paperless routines, and digitization of data.

Panel for emergency power generating unit

Simultaneously at the time of engine overhaul, a control panel used for 30 years is renovated to a new panel with the latest replacing parts and the same functions.
