Whole-Body Cryotherapy (Electric).

Industrial refrigeration compressors cool an insulated walk-in room to its target temperature (typically −85 °C). The client enters through a vestibule to prevent ambient humidity from flooding the chamber, wears dry clothing plus gloves and a hat, and stands or moves slowly for three to four minutes while an operator watches through a window. Because there is no LN2 and no open reservoir, the asphyxiation risk that defines nitrogen chambers does not apply.

The safety profile is materially better than nitrogen — no inert gas, no dewar handling, no 'head above the rim' rule, and the client can be monitored in the room with the operator if needed. Electric chambers also expose the head and neck to the cold (which nitrogen chambers cannot safely do), which some practitioners argue produces a more complete physiological response. Recent European research on cryotherapy has almost exclusively used electric chambers.

The chambers are more expensive ($80K to $150K+), the footprint is larger, and the perceived 'dramatic' factor is lower (no vapor, no visual spectacle). Electric chambers also cannot reach the −140 °C range of nitrogen, which matters for practitioners who follow protocols calibrated to the lower temperatures. For most consumer-wellness use cases, the electric range is sufficient.

Three minutes for first-timers, up to four minutes once acclimated. Some studios run five-minute electric sessions for experienced clients, but the incremental benefit beyond three minutes is contested. The full appointment is 15 to 20 minutes including intake and changing.

$50 to $100 per session — slightly higher than nitrogen on average because the equipment cost is higher and the studios are newer. Package pricing follows the same pattern as nitrogen (5-pack, 10-pack, unlimited monthly). A growing number of markets are seeing electric-only studios price at a modest premium to signal 'the safer format.'

Who is your chamber manufacturer (°Cryo, CryoAction, Mecotec, Juka, and Impact are the major names)? Is the chamber a single-room or vestibule design? What is your maximum session length? Do you allow head-first immersion? What is your client-to-operator ratio at peak hours? These questions separate studios that understand their equipment from studios that bought it off a brochure.
