FMD-4, FMD-5 specifications

The Bunn FMD-5 is a state-of-the-art coffee dispenser designed specifically for high-volume coffee brewing situations. This machine is ideal for restaurants, convenience stores, and other establishments that require an efficient and reliable coffee dispensing solution.

One of the primary features of the Bunn FMD-5 is its ability to brew and serve fresh, hot coffee with exceptional speed. The unit is capable of dispensing up to five gallons of coffee per hour, making it an ideal choice for busy environments where customer demand is high. The system utilizes a digital brewer control that allows for precise brewing temperatures and times, ensuring consistency in flavor and quality.

The FMD-5 also incorporates advanced technologies to streamline the brewing process. It features a programmable control panel that allows users to adjust settings based on their specific needs. This includes the ability to set brew cycles, control brew levels, and even program different brew strengths. The easy-to-read digital display shows real-time information, making it simple for operators to monitor the brewing process.

Another notable characteristic of the Bunn FMD-5 is its compact and space-saving design. Despite its robust brewing capacity, the unit is designed to fit easily in various retail and foodservice environments. The machine is also built with durable materials, ensuring longevity and reliability under heavy usage.

For maintenance, the FMD-5 is designed with user convenience in mind. It features removable components and accessible areas for easy cleaning and routine maintenance.
