The cold machine
A forest-green cabinet with a round dial, titanium exchanger, integrated filter and a controller that holds 3-5 °C within ±0.3 °C - 16 hours a day if your box needs it. Assembled on our own line, sized to your water.

An ice bath with a cooling system only works when the machine is sized by the water and the usage - not by the budget. The ruler: 1 HP holds up to 260 litres in a hot climate; 2 HP, 570; 4 HP, 1,200. Back-to-back sessions (box, club) call for one step up, because every body that gets in gives heat back to the water.
We pick fights with spreadsheets, not with competitors: the guide how to choose a chiller hands over the full math - thermal power, litres, recovery between sessions - even if you end up buying elsewhere.
Usually yes: we need the volume in litres and two hose pass-throughs. An adapter kit for third-party tubs ships with the installation.
Comparable to a window AC unit on low. In night mode, less - and installation on dampers kills the vibration in the deck.
