- 1Problem
Frequent micro-outages during OPD hours
Vaccine fridge tripping, examination lights flickering, and a UPS quote three sizes larger than the clinic actually needed.
- 2Diagnosis
On-site load audit, not a spec sheet
The engineer reviewed the fridge start-up demand, examination lighting, nebuliser and reception computer during normal clinic use. The essential load was much lower than the earlier whole-clinic assumption.
- 3Solution
Split design — clinical vs. comfort
Lithium UPS for the fridge and imaging cart. Tubular inverter for lights and fans. Two zones, one honest bill, everything labelled at the DB.
- 4Outcome
Reliable cold-chain continuity · lower upfront cost · right-sized backup
The clinic reports no cold-chain interruptions since installation. Routine health checks show the system is still performing well at the five-year mark, with replacement planning based on condition rather than guesswork.
