About the Project
The electrical profile of an indoor ice rink differs markedly from that of an ordinary sports hall. The refrigeration compressors that hold the ice slab at a stable temperature run continuously and form the largest single load. Add to this the dehumidification plant that prevents fog and condensation, high-illuminance field lighting and ventilation for spectator areas. A prolonged loss of refrigeration can degrade the ice surface and force it to be rebuilt.
At this scale, distribution is built on a sectionalised main board fed by two transformers. Refrigeration compressors and dehumidifiers are grouped on dedicated outgoers, keeping large motor loads apart from lighting and spectator circuits. During a utility outage the generator supplies safety lighting, evacuation systems and selected refrigeration loads. Power factor correction panels offset the low power factor of the compressor motors.
Devpan Scope and Switchboard Architecture
Devpan’s scope covers low-voltage distribution from the transformers to the boards serving the rink, refrigeration plant and spectator areas.
- Main distribution boards (DevPanel): 2 × 2,500 A busbars, 65 kA / 1 s, coupler and generator transfer; refrigeration compressor outgoers.
- Sub-distribution boards (DevBox): distribution for changing rooms, plant rooms and spectator stands.
- Power factor correction (DevComp): stepped compensation for compressor and fan loads.
- Lighting and power panels (DevPower): field lighting, general and emergency lighting circuits.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Refrigeration priority
Compressors protecting the ice are fed from dedicated outgoers and restarted in stages after an outage.
Dehumidification and condensation control
Uncontrolled humidity causes fog over the ice and condensation on the roof, so dehumidifiers need a reliable supply.
Field lighting
High-power luminaires are split into groups so that training and competition modes can use different lighting levels.
Spectator safety
Emergency lighting and evacuation systems are connected to a generator-backed safety busbar.
Frequently Asked Questions
What is the installed power of the Ice Rink Project?
For an ice rink facility of this scale, the installed power is approximately 3,200 kVA, with a typical transformer configuration of 2 × 1,600 kVA. Main busbars are typically rated 2 × 2,500 A at 10 kV, with a 1 × 1,000 kVA standby generator.
What is the largest electrical load in an ice rink?
The compressors that chill the ice slab, together with their pumps and fans, usually make up a large share of total demand and run for long periods.
Why does power factor correction matter in an ice rink?
Large motor loads draw reactive power. Compensation improves the power factor so transformer and cable capacity is used efficiently.
