The Mantis™ is the the only chiller that is designed to optimize a kitchen faucet as a chilling water source, while giving homebrewers speed and efficiency. It does this using dual 25', super efficient 1/4" copper tubing coils connected in parallel. If you are one of the many homebrewers that are restricted to using a kitchen sink, you can't chill faster than the Mantis™! The Mantis™ is perfect for anyone from a new extract homebrewer up to the experienced all-grain brewer that is relegated to a kitchen sink for their chilling water source. The Mantis™ is so finely tuned for speed AND efficiency, that a 2.5 gallon batch can be chilled in 3.5 minutes using only 7 gallons of chilling water* and a 5 gallon batch can be chilled in 7 minutes using only 14 gallons of chilling water*. Also, because of the efficiency of the Mantis™ design, the listed chilling times can be achieved using a kitchen sink, utility sink, or a garden hose spigot. The Mantis™ also features low profile chilling coils, at only 4" tall, that will be fully submerged in even the smallest of batches.
