How many sunbeds will your premises take?
Pick your beds, enter your 3-phase supply and the size of the unit. The planner adds up the power each model draws and lets you arrange the sunbed rooms on a floor plan, before you sign a lease or order a bed.
1. Your electrical supply
Your supply size is on your meter paperwork or main fuse. If you are not sure, ask your landlord or electrician.
2. Your sunbeds
No beds yet. Add the models you are considering.
3. Will the power cope?
Every bed is assumed to run at its maximum published power at the same time, as Ergoline's planning guidance requires. Current per phase is calculated from each manufacturer's maximum kW at 400V 3-phase with a power factor of 0.9. A planning estimate only: your electrician must design the supply, cabling, isolators and RCD protection.
4. Lay out the rooms
Drag rooms to arrange them. Tap a room, then use Rotate to turn it. Grid squares are 50cm. Red means a room overlaps another or sits outside the unit.

We will check the models, room sizes and supply against the unit and come back with what will work, what it costs and what your electrician needs to do.
Planning sunbeds around your power supply
Most commercial sunbeds run on a 3-phase 400V supply, and each one draws a set current on every phase whenever it is running. Premium models with more lamps and higher-output facial tanners draw more. That is why a unit with a modest supply can often run several standard lay downs but fewer flagship beds, and why the mix of models matters as much as the number.
Room size is the other limit. Allow about 2.4m to 2.5m square for most lay down rooms and around 2.0m × 1.8m for a stand up, with space for a corridor, reception and ventilation. See our room size and electrical requirements and the guide to 3-phase power and ventilation for sunbeds.
How many sunbeds can I run on a 100 amp 3-phase supply?
It depends on the models, because maximum power varies a lot between beds. Keep back about 20% for lighting, air conditioning and extraction and a 100A supply leaves roughly 80A per phase. On the manufacturers' published maximums that is about six megaSun K11 Air (up to 7.8 kW each, around 12.5A per phase) or four megaSun K9S (up to 12.3 kW each, around 19.7A per phase). The planner above does this sum for any mix of beds; an electrician must confirm the final design.
Do all the sunbeds run at full power at the same time?
In a busy salon they can, so the planner assumes every bed is running at once. That is the safe way to plan a supply. Your electrician may apply a different design basis, but should never plan for less than your busiest hour.
How big does a sunbed room need to be?
As a general guide, allow about 2.4m to 2.5m square for a lay down sunbed room and around 2.0m × 1.8m for a stand up, with a ceiling height of typically 2.4m or more for vertical units. Some larger vertical models need more. Keep clearance around the bed for ventilation, cleaning and servicing.
Is the planner a substitute for an electrical survey?
No. It is a first check so you know whether a unit is worth pursuing. The supply, cabling, isolators and protection must be designed and installed by a qualified electrician, and we confirm the exact requirement for each model before installation.
