Offices Closed temporarily! Service still available

 Cos Phi is sad to close its office temporarily. But we feel it necessary
to help do our part in combating the COVID-19 virus. Thus we will be
closed for the next 14 days.

If you need emergency service or repairs please contact us by email.
One of our service technicians will contact you
and can advise you of our current policy regarding site visits.

And isn’t this a great time to be thinking about Remote Support? 
Bet you wish you had signed up for that earlier, huh?

Otherwise, we are here and ready to talk to you about all your automation,
power factor correction, and small batch wire harness needs.

Why Preventive Maintenance Service?apfc.png

Just like an automobile, your power factor correction bank requires regular maintenance to ensure that it is operating optimally. This maintenance should be conducted on a regular annual basis (twice in the first year of a newly installed bank occurring at six month intervals)
