Freezers
1. Summary about Freezers
Freezers are refrigerating appliances designed to store food at sub-zero temperatures for long-term preservation. They are widely used in households, commercial kitchens, laboratories, and food storage facilities.
2. Why BIS Certificate is Mandatory for Freezers
BIS certification is mandatory to ensure temperature performance, electrical safety, and energy efficiency. Substandard freezers may lead to food spoilage, safety hazards, and excessive power consumption.
3. What is BIS Certified for Freezers
BIS certification verifies compliance with Indian Standards covering temperature control, insulation performance, safety requirements, and construction quality.
