What Tirunelveli's climate means for your refrigeration
- With about 147 days a year above 35 °C, a kitchen near the cooking line can run well above that. Specify units rated for 43 °C ambient so summer peaks don't push stored food out of range.
- Humidity climbs above 75% from November to December. Glass doors may fog during those months, and frost builds faster in freezers opened often — keep doors closed and seals in good order.
- Summer evenings often bring voltage drops and power cuts. Give each large unit its own earthed socket, ask about the operating voltage range, and plan backup for anything that cannot be allowed to warm up.
