Short answer<\/strong><\/p>\n\n\n\n

Electric cryo chamber running costs include cool-down, standby and use. POWERCAB lists an average power input of 3.5 kW for STORM and LIGHT. This is not a guaranteed upper limit. Using this figure, 11 operating hours and an assumed \u20ac0.30\/kWh gives 38.5 kWh and around \u20ac11.55 per day. A sub-meter provides the actual consumption at your site.<\/p>\n<\/section>\n\n\n\n

Rated power is not energy consumption<\/h2>\n\n\n\n

Cryo chamber electricity consumption is often misjudged because rated power and energy consumption get mixed up. For electric cryo chamber costs, the whole operating day counts.<\/p>\n\n\n\n

The most common mix-up with cryo chambers: kilowatts (kW)<\/strong> describe power. Kilowatt-hours (kWh)<\/strong> describe energy consumed over time. A power figure may describe an instantaneous value, an average or a maximum. Only kWh end up on the electricity bill.<\/p>\n\n\n\n

For POWERCAB STORM and LIGHT<\/a>, the manufacturer lists an average power input of 3.5 kW<\/a> and a 400 V \/ 16 A connection. One hour at 3.5 kW corresponds to 3.5 kWh. This does not establish a fixed consumption per session or a guaranteed upper limit for a day.<\/p>\n\n\n\n

Three phases: cool-down, standby, use<\/h2>\n\n\n\n

Over the day, an electric cryo chamber passes through three phases you should consider separately:<\/p>\n\n\n\n

    \n
  1. Cool-down:<\/strong> from room to operating temp.<\/li>\n\n\n\n
  2. Standby:<\/strong> holding temp., no guest<\/li>\n\n\n\n
  3. Use:<\/strong> sessions, door openings, re-cooling<\/li>\n<\/ol>\n\n\n\n
    \n

    Energy (kWh) = average power input (kW) \u00d7 operating hours (h)<\/strong><\/p>\n\n\n\n

    For an initial estimate, multiply the assumed average power input<\/strong> by operating hours. For a more precise calculation, measure cool-down, standby and use separately.<\/p>\n\n\n\n

    The manufacturer\u2019s average figure is not a measured load profile for your site. Room temperature, ventilation and use affect consumption. Measure actual kWh with a sub-meter.<\/em><\/p>\n<\/div>\n\n\n\n

    Worked example for one operating day<\/h2>\n\n\n\n

    The following values are explicit assumptions<\/strong> for a worked example, replace them with your own:<\/p>\n\n\n\n

    \n

    3.5 kW \u00d7 11 h = 38.5 kWh per day (calculation figure)<\/strong><\/p>\n\n\n\n

    38.5 kWh \u00d7 \u20ac0.30 = \u20ac11.55 per day<\/strong> \u00b7 \u00d7 26 days = around 1,000 kWh or \u20ac300 per month<\/strong>, as an estimate.<\/p>\n\n\n\n

    Actual consumption may be higher or lower than this estimate. An average figure does not establish a consumption ceiling.<\/em><\/p>\n<\/div>\n\n\n\n

    Every door opening costs a little re-cooling, yet with high utilisation, electricity cost per session still falls.<\/figcaption><\/figure>\n\n\n\n

    Electricity cost per session: utilisation decides<\/h2>\n\n\n\n

    Because much of the energy goes into cool-down and standby, daily costs are spread across sessions. The more sessions, the lower the electricity share per session<\/strong>:<\/p>\n\n\n\n

    Sessions per day<\/th>Electricity cost per session (example)<\/th><\/tr><\/thead>
    10<\/td>approx. \u20ac1.16<\/td><\/tr>

    60<\/td>approx. \u20ac0.19<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Basis: \u20ac11.55 per day from the worked example. Additional sessions slightly increase consumption through door openings and re-cooling, again, only a measurement shows the effect.<\/p>\n\n\n\n
