Hybrid recharge
Tropical night? Top up off-peak.
When night air is not cool enough, a compact recharge unit — or the AC you already own — quietly refreezes the cartridges during off-peak hours. The Studio Hub does the scheduling; the modules do the rest.
See the full cycleAll-season
One platform. Every season.
The same high-conductivity cartridge comes in a range of phase-change temperatures — coolth packs for summer, heat-storage packs for winter. Swap the bank when the season turns.
Summer
22–26°C
Night air — or off-peak AC — freezes the cartridges. By day they absorb the room's heat and a quiet fan spreads the coolth.
Winter
~32°C
Swap in heat-storage cartridges. A small fan heater or air-source heat pump charges them during off-peak hours; they release gentle, even warmth for hours after.
Because PCM charges and discharges at a nearly constant temperature, it clips the peaks and troughs of the day — the room holds a steady, comfortable band instead of swinging hot and cold. Your body feels the difference: steadier rooms mean deeper sleep and calmer days.
