What Kolkata's climate means for your refrigeration
- With about 49 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.
- Average humidity is 77% across the year, peaking near 87% in August. Expect condensation on glass doors and cabinet edges; heated or double-glazed glass and a well-drained defrost system matter here.
- Humid air is also hard on condenser coils and steel. Keep coils clean, check door gaskets often and choose stainless steel interiors that resist corrosion.
- 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.

Equipment for Kolkata
What to specify, product by product.
- +2 to +8 °CReach-in Refrigerator in KolkataPrefer fan-forced (ventilated) cooling: it recovers temperature faster after the door is opened, which matters most during April service.City checklist
- +2 to +8 °CUndercounter Refrigerator in KolkataChoose a front-breathing design if the unit will be built into a counter run — rear-breathing undercounters starve for air in a closed bay.City checklist
- +2 to +10 °CGlass Door Refrigerator / Visi Cooler in KolkataSpecify double-glazed or heated-frame glass doors. With Kolkata's humidity averaging 77%, single glass will fog and hide the stock.City checklist
- +4 to +10 °CDisplay Cases & Showcases in KolkataDisplay glass fogs easily in Kolkata's humid air (77% average). Ask about anti-fog or heated glass and keep the case away from doors that let in outside air.City checklist
- −18 to −60 °CDeep Freezer in KolkataCheck that the freezer holds −18 °C or colder at 43 °C ambient — many chest freezers lose margin in April, and ice cream softens first.City checklist
