Water-Cooled Beeswax Foundation Machine

01 · WHAT ELSE YOU NEED

Tank, pump and hoses

The mould is cooled by recirculating water, so the circuit has to be built around it: a tank of at least 50 litres and a submersible pump of 1,000 to 1,500 litres an hour with at least a metre of head.

One hose carries cold water from the tank to the machine and another returns it. None of that is included, and without it the machine does not work.

02 · YOUR OWN WAX IS NOT AUTOMATICALLY PURE

Traceability is not the same as purity

Making your own foundation gives you something real: you know where the wax came from, and you avoid the uncertainty of a market where adulteration with paraffin and other fats is a known problem.

What it does not automatically give you is wax free of residues. Several acaricides are fat-soluble and accumulate in wax, so recycling wax from treated colonies recycles what it carried too. If you are coming off years of treatments, consider renewing the cycle with fresh wax rather than recycling indefinitely.

03 · THE WATER IS THE VARIABLE

Neither too cold nor too warm

The sheet forms because the wax solidifies against the cold mould, and there the water governs. Too cold and the sheet cracks as it chills too fast; too warm and it does not set, deforming as you peel it off.

The large tank is exactly for that: 50 litres hold the temperature steady through a run, whereas a small bucket warms up quickly and the result starts drifting from sheet to sheet.

04 · THE WAX AND THE TIME

70-75 °C, and let it rest

The wax is poured molten and fluid, around 70-75 °C: at its melting threshold, 62-65, it is already thick and the cell pattern comes out without definition.

And a freshly made sheet needs to rest. Straight out of the mould it is brittle; stacked flat somewhere cool for a few days it stabilises and stands up far better to wiring and handling.

05 · BEFORE YOU BUY

Add the 50-litre tank and the submersible pump to the price: without the water circuit the machine does not run.
