Hoshizaki KML-200MWE, KML-200MAE service manual Controller Board

KML-200MWE, KML-200MAE specifications

The Hoshizaki KML-200MWE and KML-200MAE are commercial ice machines renowned for their high performance and reliability in the foodservice industry. Both models are designed to meet the needs of businesses that require a consistent supply of ice for various applications, including restaurants, bars, and hotels.

One of the standout features of the KML-200MWE and KML-200MAE is their ability to produce high volumes of crisp, clear ice. These machines utilize a combination of advanced refrigeration technology and a unique ice-making process that ensures a rapid ice production rate while maintaining energy efficiency. The modular design allows for easy integration into existing setups, making them an ideal choice for operators looking to expand their ice supply without a complete equipment overhaul.

The KML-200MWE features a built-in water-cooled condenser, allowing for operation in environments where air-cooled systems may not be viable. This feature is particularly useful in warm climates or kitchens with limited ventilation, as it ensures that the machine operates efficiently, regardless of external temperatures. In contrast, the KML-200MAE incorporates an air-cooled condenser, making it a more flexible option for operators who prioritize energy savings and ease of maintenance.

Both models utilize a unique fluorinated refrigerant, which not only enhances their cooling efficiency but also aligns with modern environmental standards. The internal components are constructed from high-quality stainless steel, ensuring durability and resistance to corrosion. Moreover, their easy-to-access design simplifies maintenance routines, enabling operators to keep the machines running smoothly with minimal downtime.

Another key feature of the KML-200MWE and KML-200MAE is their ice storage capacity. With an ample bin size, these machines can store a significant amount of ice, reducing the need for frequent refills and making them ideal for busy establishments. Additionally, they are equipped with automatic ice level controls, which help maintain optimal ice quantities while preventing overflow.

Hoshizaki ice machines are also recognized for their innovative air filtration systems, which improve the quality of the ice produced. This ensures that the ice is not only abundant but also free from any contaminants, meeting the high standards of hygiene expected in the food industry.

In summary, the Hoshizaki KML-200MWE and KML-200MAE are exemplary models that blend technology, efficiency, and durability. Their advanced features make them suitable for various commercial applications, providing operators with reliable performance and peace of mind. Whether choosing the water-cooled or air-cooled variant, businesses can expect a high-quality product that enhances their ice production capabilities.
