NOTE:We have a lot of different heating elements. Which one is right for you depends on your kettle diameter and your power outlets.To calculate how long heating water will take, use this formula:Volume in liters * 4200 / power of element in watts = seconds per degree CelsiusDescription:Voltage3 phase 230v(Y or Star configuration)1 phase 230vPower8500wCurrent3 x 12.3A or 1 x 37AWatt density7.5w/cm2Minimum Kettle Size41cmElement materialSS316Flange and housing materialSS304The new elements have several advantages over straight or fold back elements:● More power means faster rise times and a more vigorous boil.● Because of the extra length, they have really, really low watt density. They simply do not scorch. You don't have to scrub after brewing.● Because of the round shape, they have better heat distribution in the kettle.● The round shape doesn't get in the way of a good whirlpool.● The flange has an integrated O-ring, which is completely hidden once mounted.● The flange has a middle screw for grounding to ensure safe operation.● The custom mounting kit makes it very easy to mount them in any kettle. You only need a 47mm hole punch and a large wrench (54mm).You maybe interested in the following productApplication: CertificationsDelivery&Package1. Lead time: 7-15 days after payment2.
