CASTA Professional Gas Hob Surface P7/CUPG4BB.2M2G

A gas hob surface engineered for continuous use in professional kitchens, where open burners deliver instant, adjustable heat directly to pans and pots. The hob draws natural gas or propane through separate valves to each burner, where a manual ignition spark lights a small pilot flame. This flame heats a thermocouple that holds the gas valve open; if the flame fails, the valve closes within seconds, cutting the gas supply and preventing leaks. The open design of the burners allows the flame to wrap around the base of the pan, transferring heat quickly and evenly without the insulation of a sealed burner cup. Cast-iron grates sit above the flames, supporting heavy stockpots and frying pans while withstanding the high temperatures and thermal shock of daily service.

To operate the hob, the chef turns the control knob for the chosen burner to the ignition position, presses it to release gas and generate a spark, then holds it until the pilot flame is established. Once the thermocouple is hot, the knob can be released and turned to the desired flame size. Each burner offers a low simmer setting for delicate sauces and a full-power setting for rapid boiling or searing. The two larger burners provide the high output needed for wok cooking or large stockpots, while the two smaller burners suit sauté pans and smaller vessels. After use, the chef turns the knob to the off position, extinguishing the flame and allowing the hob to cool.

The hob is constructed from 18/10 AISI 304 stainless steel, a grade chosen for its resistance to corrosion, acids and mechanical damage. The worktop is pressed with a recessed trough around the burners to collect spills and liquids, simplifying cleaning and keeping the surrounding area dry. The cast-iron burners are chrome-plated for durability and ease of maintenance, while the grates are coated with high-temperature porcelain enamel that resists staining and chipping. Control knobs and handles are made from heat-resistant material that remains cool to the touch even after prolonged use, reducing the risk of burns. Adjustable legs, also in stainless steel, allow the hob to be levelled on uneven floors or matched to the height of adjacent worktops.

The power ratings of 4.5 kW and 7.5 kW per burner indicate the maximum gas load each valve can supply, determining the speed at which the hob can bring liquids to the boil or sear ingredients. The 700 mm width and depth provide space for four simultaneous cooking zones without crowding, while the 305 mm height keeps the worktop at a comfortable level for standing chefs. The stainless steel construction and pressed worktop simplify daily cleaning; the recessed trough can be wiped down after service, and the porcelain-coated grates can be removed for scrubbing. The open burners and chrome-plated components require occasional brushing to remove carbon deposits, ensuring consistent flame quality and safety.

The hob is certified to European Union safety and quality standards, confirming its suitability for commercial environments where reliability and compliance are essential.
