The KB10 wort plate chiller is a highly-efficient, compact plate-type wort chiller. This chiller is made of 10 plates of 316 stainless steel that have been brazed together with pure copper in an oxygen-free furnace. The KB10 has a bit less surface area than the KB40, but in our testing, it was still very effective at rapidly reducing wort to pitching temperatures. This chiller has 1/2" NPT threaded male hookups for the wort and Male Garden Hose fittings for the chilling and waste water. Wort may be pumped or gravity fed through the chiller.
