Upgrade & Retrofit


For the last two decades huge investments has been made in internet and telecom infrastructure. Capacity need to be higher and old equipment is having operational problems like high temperature, unstable power supply, and humidity/corrosion problems). Equipment are therefore undergoing upgrades and retrofit worldwide.


Cooling equipment powered by AC is changed to DC powered. Cabinets and shelters need higher and more precise cooling capacity. Old cabinets are retrofitted with cooling and bad quality purchases are replaced with better. Shelters are upgraded with free cooling and other places free cooling /filter products are replaced with heat exchangers and air conditioner.

All are done in order to improve uptime/ availability.


Contact VIKINOR in order to get good suggestions for upgrade/retrofitting.
