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 PCM modules during off-peak hours. The Studio model calculates a suggested recharge window; your own timer or control equipment operates the hardware.
See the full cycleAll-season
One platform. Every season.
The same high-conductivity module platform comes in six phase-change temperatures — 22 / 24 / 26 / 28 / 30 / 32°C. Swap the bank when the season turns.
Summer
22–32°C
Night air — or off-peak AC — recharges the PCM modules. By day they absorb the room's heat and a quiet fan spreads the coolth.
Winter
~32°C
Swap in higher-temperature PCM modules. 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.
