KML "F" SERIES, KML "H" SERIES specifications

The Hoshizaki KML "H" Series and KML "F" Series are state-of-the-art commercial ice machines designed to meet the diverse needs of the foodservice industry. Renowned for their reliability, efficiency, and innovative technology, these ice machines are perfect for restaurants, bars, and hotels seeking high-quality ice production.

The KML "H" Series focuses on producing crescent cubed ice, a preferred choice for many establishments due to its slow melting rate and ability to chill beverages effectively. One of the main features of the "H" Series is the ice-making process, which utilizes advanced technology to ensure a quick production cycle. The machines come with a variety of capacities to suit different business sizes, ranging from small-scale operations to large commercial needs.

The KML "F" Series, on the other hand, is designed to produce flaky ice, which is ideal for display in seafood and salad bars. This series stands out with its unique ice texture, perfect for preserving freshness and enhancing presentation. The "F" Series also boasts high production rates, ensuring a continuous supply of ice even during peak hours.

Both series come equipped with Hoshizaki's exclusive Cascade Ice Making System, which enhances water flow and improves efficiency, leading to lower energy consumption. This is complemented by an exterior that is easy to clean and maintain, reducing labor costs associated with upkeep.

Key characteristics of the KML Series include durable stainless-steel construction, providing longevity and resistance to corrosion. Moreover, both series feature a self-diagnostic control system that alerts users to potential issues before they become significant problems, thereby minimizing downtime.

In addition to their robust design and performance, they also incorporate environmental considerations. Hoshizaki machines are engineered to operate using refrigerants that have a lower impact on the ozone layer, making them compliant with global environmental standards.

Overall, the Hoshizaki KML "H" Series and KML "F" Series stand out in the competitive landscape of commercial ice machines, combining innovative technology, exceptional durability, and user-friendly features to provide a reliable ice-making solution for various foodservice applications.
