Roller-grill WD780S Heated Showcase for Professional Kitchens

A heated showcase keeps prepared dishes at serving temperature without drying them out or overcooking. The Roller-grill WD780S uses a ventilated firestone system: an Incoloy heating element warms a ceramic stone that stores and radiates heat evenly. Two fans circulate the warm air throughout the cabinet, eliminating cold spots and maintaining a steady temperature across every shelf. This method prevents the surface crusting that static heat can cause, so quiches, pizzas, meatballs and pastries stay moist and appetising for hours.

The operator loads the two supplied wire grids or optional Gastronorm GN 1/1 trays with cooked items, sets the electronic thermostat between +20 °C and +90 °C, and switches the unit on. The LED lighting illuminates the display, while the fans and heating element bring the cabinet to the chosen temperature. A water drawer beneath the lower tray adds humidity, counteracting the drying effect of the warm air and preserving the texture of delicate pastries and delicatessen. The rear glass doors open fully to 180°, giving clear access for loading and unloading.

The WD780S is built in stainless steel with a toughened glass front and sides. Inside, the lower tray, water drawer, firestone and grid supports are all removable for thorough cleaning. The two wire grids measure 670 mm by 433 mm each and can be lifted out separately. An on/off switch controls the entire unit, while a separate ventilation switch allows the fans to run independently for cooling or air circulation without heat.

A power rating of 1.2 kW indicates the load on the electrical circuit; the showcase requires a standard 230 V single-phase supply. The external dimensions of 780 mm wide, 490 mm deep and 480 mm high determine the space it occupies on a worktop or counter. At 30 kg, the unit is light enough to be moved by one person but stable enough to remain in place during service. The temperature range of +20 °C to +90 °C covers holding for most hot snacks, pastries and plated dishes without risking further cooking or drying.

Cleaning involves removing the grids, lower tray, water drawer and firestone, washing them in hot soapy water, and wiping down the interior with a damp cloth. The glass doors and stainless steel exterior can be cleaned with standard kitchen sanitiser. The unit is available in stainless steel or black finish, and additional wire grids can be ordered separately.

The WD780S fits Gastronorm GN 1/1 trays (400 mm by 600 mm) and can also hold three American-style hotel pans side by side. It is categorised as a counter-top heated display for professional catering environments.
