100 cup coffee maker

Common commercial sizes are listed in liters: 12 L, 14 L and 18 L; some listings also note a 16 L option for very large batches.

Many commercial urns report brewing a full 100-cup batch in about 40 minutes; several models list a general large-batch range of roughly 40–60 minutes depending on the unit.

These urns commonly use commercial-grade stainless steel (often specified as 304) and double-wall construction or insulation to improve heat retention.

Common dispensing features include reinforced, drip-free (often brass) spigots for clean pouring, plus visible water-level gauges or clear volume markers to monitor remaining coffee.

These high-capacity urns are intended for large gatherings and high-volume service, such as weddings, catering, conferences, churches, offices, buffets, and similar events.
