FAGOR MRBIG-200 M 200 L Indirect Gas Boiling Kettle

A boiling kettle heats liquid indirectly by circulating hot gases through a jacket around the vat, preventing scorching and allowing precise temperature control. The heat transfers evenly through the stainless steel walls, warming the contents without direct flame contact. This method is essential for delicate stocks, sauces and stews that must not burn or stick, while the jacket also retains heat for consistent cooking over long periods.

The operator fills the 200 L vat through the top inlet, sets the desired temperature and mixing speed on the PLC touchscreen, and starts the programme. The gas burners ignite automatically via the piezo ignition, heating the water in the jacket. A manometer monitors pressure inside the jacket, while a safety valve releases excess pressure at 0.5 bar. The adjustable mixer, with Teflon-ceramic blades, rotates between 7 and 28 rpm, preventing hot spots and ensuring even cooking. When the cycle finishes, the kettle signals completion with a sound alert and yellow indicator light. Hot liquid is drained through the chrome-plated bronze tap, which also supplies cold water for rinsing or cooling.

The vat is constructed from AISI 316 stainless steel with a thickness of 20/10 to 40/10 mm, while the outer jacket and lid use AISI 304 stainless steel in 20/10 to 25/10 mm and 15/10 mm respectively. The lid features a counterbalanced closing mechanism and heat-resistant handle for safe operation. A fine satin finish on the outer walls resists fingerprints and scratches, while the worktop, also in AISI 304, provides a durable surface for preparation. The supporting frame, 40/10 mm thick, stands on adjustable feet for levelling on uneven floors.

The PLC touchscreen allows up to 100 customisable cooking programmes, each adjustable mid-cycle for temperature, mixing speed, water fill and timing. A water-level sensor prevents dry running, and the mixer's tilt and movement are controlled electronically. The gas system includes a pilot light, flame failure safety, and a flue grid for exhaust gases. A kit of nozzles adapts the burners to different gas types, ensuring compatibility with natural gas or propane supplies.

A 200 L capacity suits large batches of soups, stocks or sauces, reducing the need for multiple smaller vessels. The 35.75 kW power rating requires a dedicated gas supply and a 400 V three-phase electrical connection for the control system. At 620 kg, the unit is moved with a pallet truck or forklift, while its 1674 x 1450 x 1140 mm footprint demands a fixed position near gas and water lines.

Cleaning involves draining the vat, removing the mixer for separate washing, and wiping the interior with non-abrasive cleaners. The Teflon-ceramic blades release food residues easily, and the satin finish on the exterior resists stains. The lid's counterbalance mechanism and the mixer's tilt function simplify access for deep cleaning. Regular checks of the safety valve, manometer and gas nozzles maintain safe operation.

The MRBIG-200 M is a gas model with indirect heating, designed for professional catering environments requiring large-scale liquid cooking with precise control.
