FAGOR MRIG-500 A Gas Boiling Kettle – 500 L Capacity

A gas boiling kettle heats liquids by circulating hot gases through a sealed jacket around the cooking vessel, transferring heat evenly without direct flame contact. This indirect method prevents scorching and allows precise temperature control, essential for large batches of stocks, soups or sauces. The jacket's pressure accelerates heat transfer, reducing cooking times while maintaining consistent results across the entire 500 litre capacity.

To operate, the kettle is filled through the hinged lid, which seals with a chrome-plated locking mechanism and heat-resistant handle. The pilot light is lit manually via a piezoelectric ignition, and the main burners fire beneath the stainless steel tubular heat exchanger. Once the desired temperature is reached, the contents are stirred or left to simmer, monitored through the lid's viewing window. When ready, the insulated drain tap at the front is opened, directing the liquid into containers without risk of burns from exposed metal.

The cooking vessel is constructed from AISI 316 stainless steel with a thickness of 20/10 to 40/10, chosen for its resistance to corrosion and acidic ingredients. The surrounding walls and lid use AISI 304 stainless steel in 20/10 to 25/10 gauges, while the satin-finished outer panels and worktop are 10/10 and 15/10 respectively. The supporting frame, also stainless steel, stands on adjustable legs to level the unit on uneven floors. An autoclave version is available, featuring a food-grade silicone gasket and locking clamps for hermetic sealing, with a safety valve set to 0.05 bar to prevent over-pressurisation.

The 55 kW power rating indicates the load on the gas supply, suitable for high-volume production in commercial kitchens. At 400 kg, the kettle requires a sturdy floor and may need specialist handling equipment for installation. The 1300 x 1400 x 1000 mm footprint demands dedicated space, typically positioned against a wall with clearance for the flue grille at the rear. The indirect heating system includes a pilot light for continuous ignition and a manual piezo starter for reliability during frequent use.

Cleaning involves scrubbing the AISI 316 vessel with non-abrasive pads to preserve the surface, while the drain tap can be disassembled for descaling. The lid's locking mechanism should be checked regularly for smooth operation, and the flue grille cleared of debris to maintain efficient combustion. The adjustable legs should be inspected for stability, particularly after moving the unit.

An autoclave variant is offered for applications requiring pressurised cooking, with additional sealing components and a safety valve to manage internal pressure. The kettle can be installed as a standalone unit or integrated into a larger kitchen layout alongside other professional equipment.
