CASTA E7/CUPG4BB.4M 70 cm Professional Gas Hob

A gas hob built for the demands of a professional kitchen, where open flames deliver instant, controllable heat across four high-output burners. Gas flows through the burner ports and is ignited, producing a direct flame that transfers heat immediately to pots and pans without the lag of electric elements. The intensity of each burner is adjusted by turning the control knob, giving the chef precise temperature control for searing, simmering or boiling. Because the heat source is visible and responsive, the operator can see the flame height and react in seconds to changes in the cooking process.

The sequence begins with manual ignition: the control knob is pressed and turned to the ignition position, lighting the protected pilot flame. Once the thermocouple senses heat, the gas valve stays open; if the flame goes out, the valve shuts off automatically, preventing unburned gas from escaping. Each burner is lit individually, allowing the chef to start with one or two as needed and add more as the service progresses. Pots and pans rest on cast-iron grates that conduct and retain heat, spreading it evenly across the base of the cookware. The grates are sized so that a single pan can span two burners for larger tasks, or two smaller pans can be used side by side.

The worktop is 700 mm square and made from 18/10 AISI 304 stainless steel, chosen for its resistance to corrosion and staining in a busy kitchen. A 22 mm deep recessed channel runs around the perimeter, collecting spills and juices so they do not spread across the surface or drip onto the floor. The channel is sloped to one corner, where a removable drain plug allows quick cleaning between services. Four adjustable legs, also in stainless steel, level the hob on uneven floors and raise it to a comfortable working height.

Each burner is cast from chromed cast iron and fitted with a thermoelectric safety device that cuts the gas supply if the flame is extinguished. The control knobs are heat-resistant and designed with a cool-grip surface, so they remain safe to touch even after prolonged use. The grates are coated with a glossy porcelain enamel that resists acids and alkalis, preventing corrosion and making them easy to wipe clean after service.

The power rating of 4.5 kW per burner indicates the maximum gas load each burner can draw, which determines the size of the gas supply line and the total load on the kitchen's gas system. Four burners at full output require a robust gas connection capable of delivering the combined flow without pressure drop. The 700 mm width matches standard worktop depths in professional kitchens, fitting into a run of countertop equipment without overhang. The 275 mm height allows the hob to sit flush with adjacent appliances, maintaining a continuous work surface for food preparation and plating.

Cleaning is straightforward because the design minimises crevices where food can lodge. The recessed channel is wiped out after each service, and the drain plug is removed to flush away residue. The porcelain-coated grates and stainless steel worktop can be scrubbed with non-abrasive cleaners without damaging the finish. The control knobs lift off for access to the burner assembly, and the thermocouple and pilot assembly are designed for easy replacement if needed.

The hob is certified to European Community safety standards, confirming it meets the requirements for gas appliances in professional kitchens. It is supplied as a single unit with no variants or optional extras listed.
