CDBC TC, CDBC APS, CDBCF TC, CDBCF APS specifications

The Bunn CDBCF series of coffee brewers is an essential tool for any coffee business, renowned for its reliability and efficiency. This series offers different models including the CDBCF APS (Automatic Pour-Over) and CDBCF TC (thermo carafe), among others. Each of these brewers is designed to produce exceptional quality coffee while ensuring ease of use.

One of the main features of the Bunn CDBCF APS is its automatic pour-over capability, which ensures that water is heated to the perfect brewing temperature and dispensed consistently. This model is equipped with a stainless steel water tank that maintains optimal water temperature, resulting in flavorful coffee extraction. Furthermore, the APS model allows for quick brewing cycles, producing up to 3.8 gallons of coffee per hour, making it ideal for high-demand environments.

The CDBCF TC model, on the other hand, utilizes a thermal carafe to keep coffee hot for extended periods without the need for a hot plate. This technology not only preserves the coffee’s flavors and aromas but also minimizes energy consumption. The thermal carafe can hold up to 1.9 liters of brewed coffee, making it efficient for serving in busy settings.

Both models in the CDBCF series come with a simple interface for straightforward programming and operation. Features such as the BrewLOGIC technology help regulate the brewing time and monitor water flow to ensure consistency. This is particularly beneficial in maintaining the quality of coffee across multiple brewing batches.

In terms of build quality, Bunn CDBCF brewers are constructed with durable materials designed to withstand the wear and tear of daily use in busy coffee shops. Their compact design requires minimal counter space while providing a high volume of output.

Overall, the Bunn CDBCF APS and TC models stand out for their advanced brewing technologies, versatility, and user-friendly design. They cater perfectly to coffee enthusiasts and business owners looking for reliable brewing solutions that deliver consistent quality and taste. With the Bunn CDBCF series, coffee brewing becomes not only an art but also an efficient and seamless process.
