MD-44, MD-66 specifications

Moyer Diebel has established a reputation as a leader in the commercial dishwashing industry, known for producing technologically advanced and reliable machines. Among their popular models are the MD-66 and MD-44, both designed to meet the needs of high-volume establishments. These machines exemplify Moyer Diebel's commitment to quality and efficiency.

The MD-66 is an energy-efficient dish machine suitable for large restaurants, hotels, and institutional kitchens. With a capacity to wash up to 66 racks per hour, it significantly speeds up the dishwashing process, making it ideal for busy environments. Its unique design features a dual rinse system that ensures consistent and thorough cleaning, while its adjustable wash cycles allow operators to customize the washing intensity based on the type of load – whether heavily soiled pots or delicate glassware.

Equipped with advanced technology, the MD-66 incorporates a microprocessor control system, providing users with real-time feedback on machine performance and diagnostics. This feature helps facilitate preventive maintenance, reducing downtime, and ensuring operational efficiency. The built-in energy efficiency measures contribute to lower utility costs, making this machine not only effective but also environmentally friendly.

Similarly, the MD-44 is designed for smaller establishments that still demand high efficiency. With a capacity of 44 racks per hour, it strikes a balance between compact design and powerful performance. This machine is particularly appealing for cafes, small restaurants, and catering operations. The MD-44 shares many features with the MD-66, including adjustable wash cycles and a robust rinse system, ensuring that even smaller operations receive the same level of cleanliness and hygiene.

Both the MD-66 and MD-44 utilize advanced spray technology, providing optimal water distribution to maximize cleaning effectiveness while minimizing water usage. The user-friendly interfaces on both models simplify operation, ensuring that staff can quickly learn to use the machines without extensive training.

In summary, Moyer Diebel’s MD-66 and MD-44 dishwashing machines combine high capacity, innovative technology, and efficiency to meet the varying needs of different sizes of commercial kitchens.
