The National 12L Halogen Oven is a highly efficient, multi-functional countertop cooker popular in Sri Lanka. It combines a powerful halogen heating element with a high-speed convection fan inside the lid to circulate intense heat rapidly through a heavy-duty 12-liter glass bowl.
Key Specifications & Summary
Cooking Technology: Uses a combination of instant halogen heat, infrared energy, and convection air circulation. It cooks up to 40% faster than a conventional oven and requires no preheating.
Capacity: 12 Liters (ideal for a family meal or a whole roast chicken). Many units include a metal extender ring that bumps the capacity up to 17 Liters for larger dishes.
Controls: Simple manual dual-dial controls on the lid:
Temperature Dial: Ranges from 60°C to 250°C.
Timer Dial: Up to 60 minutes with an automatic safety shut-off when the handle is lifted.
Versatility: Functions as an air fryer, traditional oven, grill, toaster, and defroster all in one.
Accessories Included: Usually packed with a high rack (for grilling/crisping), a low rack (for baking/roasting), and safety tongs to lift hot racks out of the bowl.
Why it's popular: It drains away excess fat for healthier meals, saves on electricity compared to large built-in ovens, features a handy self-cleaning mode (using warm water and soap on a low setting), and lets you monitor your food from any angle through the clear glass bowl.
