At 15–25 animals, milking time stops being an inconvenience and starts being a labor cost problem — you either need more hands or more clusters running at once. The 3 in 1 runs three milking clusters off a single higher-capacity vacuum pump, so three animals are milked in parallel instead of two.
This model sits between our 2-in-1 and our Double Bucket commercial unit, and it's the one we point growing farms toward when they're not yet running a full commercial-scale two-operator setup but have clearly outgrown a twin-cluster machine. The larger pump has to work harder to hold consistent vacuum across three clusters simultaneously, which is why the motor and pump specification step up here rather than just adding a third bucket to the 2-in-1's pump. As with our full range, this machine is manufactured at our Bangalore facility and is supplied to both Indian farms and overseas distributors.
