DIHR OPTIMA 500HR 24-Inch Undercounter Dishwasher

DIHR has functioned as a leading global authority in commercial warewashing and sanitation systems since its founding in 1985. Based in Castelfranco Veneto, Italy, the company operates within the Ali Group, one of the world's largest foodservice equipment conglomerates. DIHR is distinguished by its highly automated production capabilities, manufacturing a complete professional machine every few minutes from its high-tech Italian facility. The brand serves as a primary infrastructure provider for hotels, hospitals, and high-volume catering operations in over 120 countries.

The brand's technical identity is defined by its vertically integrated manufacturing and specialized metallurgy. A primary engineering hallmark is the use of AISI 304 and 316-grade stainless steel, with many boilers specifically utilizing 316-grade to ensure long-term resistance to mineral scaling and chemical corrosion. DIHR is recognized for its ability to produce the "broadest range" of washing equipment in the industry, from compact undercounter units to massive flight-type conveyor systems, all engineered with a focus on modularity and rapid on-site assembly.

Innovation at DIHR is categorized by two distinct technological pillars: the Twin Star system and Granule washing.

• Twin Star (Stock & Wash): This represents a departure from traditional warewashing. It is an upright, multi-level stacking washer that allows dishes to be washed, dried, and stored in the same footprint. It is engineered to save approximately 65% of the space required by traditional dishwashing lines and reduces labor requirements by up to 90% by eliminating the need for constant loading and unloading of baskets.
• Granule Technology: Designed for the most intensive pot and pan cleaning, these machines utilize the abrasive power of recyclable plastic granules mixed with water. This mechanical action eliminates the need for manual soaking or scrubbing, significantly reducing water and chemical consumption while accelerating the turnaround of heavy-duty cookware.
• Optima and IoT Integration: The Optima series features "clean water" technology and integrated WiFi connectivity, allowing operators to monitor HACCP data, energy consumption, and detergent levels remotely through a centralized digital interface.

The product portfolio is segmented by volume and specialized application:

• Undercounter and Hood-Type: Including the GS, DS, and Electronic lines, designed for bars and restaurants with a focus on double-skin insulation for heat retention and noise reduction.
• Rack and Flight Conveyors: Large-scale industrial systems with reinforced double-rinse cycles and optional heat recovery units to pre-heat incoming water using waste steam.
• Pot and Utensil Washers: High-torque machines with large wash chambers for trays, crates, and bakery equipment.
• Granule Warewashers: Specialized units for removing carbonized food and encrusted proteins from GN-sized pans.

The strategic value of DIHR lies in its efficiency-first design and its robust global support network. By optimizing the "life cycle cost" of their equipment, the brand provides a high-yield foundation for operations seeking to minimize utility bills and chemical waste. Supported by a comprehensive inventory of factory-authorized parts and a strong presence in the North American market, DIHR remains a foundational partner for the modern, sustainable commercial kitchen.
