Eltrode delivered comfortable cooling to thousands of festivalgoers

‍

The weekend of Tons of Rock 2026 turned out to be one of the warmest festival weekends in a long time. On Saturday, temperatures hit around 30 °C in the shade, turning the massive tents into virtual greenhouses as thousands of people gathered under canvas.To ensure a healthy indoor climate, an Eltrode CHP 50.2 inverter heat pump was deployed to handle the cooling. The impact was felt immediately.

Results:

• Approx. 10 °C supply air into the tent
• Over 10,000 m³ of cooled air per hour
• Significantly reduced indoor temperature
• Comfortable conditions despite high crowd density
• 100% stable operation throughout the entire event

The powerful airflow ensured continuous replacement of the hot air trapped inside the tent. This combination of high air capacity and cold supply air provided a cooling effect that was greatly appreciated by both the audience and the organizers.

Built for demanding conditions

The CHP 50.2 is engineered for professional applications where standard comfort systems fall short.

Technical highlights:

• 38 kW cooling capacity
• Inverter-driven compressor
• Operating range from -35 °C to +43 °C
• Over 10,000 m³ air/hour
• Fast installation with flexible air ducts
• 400V industrial power supply

Energy-efficient operation compared to traditional cooling solutionsThanks to inverter technology, the heat pump automatically adjusts its output based on demand. This ensures both lower energy consumption and a stable temperature throughout the event.

Perfect for events

Festivals and concerts are just one of many applications.

The CHP 50.2 is ideal for:

• Festival tents
• VIP areas
• Concert tents
• Dining and bar areas
• Trade shows
• Exhibitions
• Sports halls
• Temporary structures
• Warehouses
• Production halls
• TV productions
• Film sets
• Event locations
• Emergency response
• Military installations
• Offshore applications
• Large workshops

Comfort drives better experiences

On hot summer days, cooling is about much more than just numbers on a thermometer.

A cooler indoor climate ensures:

• More satisfied guests
• Longer dwell time
• A better working environment for staff
• Reduced heat stress
• Lower humidity levels
• Fresher air
• An enhanced overall experience

For organizers, this can be the defining factor between a tent that people leave after a few minutes, and an area where the audience wants to stay.

Mobile cooling whenever the need arises

One of the greatest advantages of the CHP 50.2 is its mobility.The unit can be delivered, connected, and put into operation in a short amount of time without the need for permanent installations. It can easily be relocated between different areas during the event if requirements change.

This makes the solution ideal for:

• Temporary events
• Acute cooling needs
• Seasonal installations
• Projects where permanent air conditioning is not viable

Proven performance – even at the height of summer

During Tons of Rock 2026, the CHP 50.2 proved that a mobile inverter heat pump can deliver professional-grade cooling even under the most demanding conditions.

While outdoor temperatures neared 30 °C, the system supplied roughly 10 °C cold air with a massive volume of 10,000 m³ per hour, keeping one of the festival’s main tents comfortable during the hottest part of the weekend.

When thousands of people gather under one roof, climate control is not a luxury – it is a vital part of the overall experience.

The CHP 50.2 delivered exactly what it was designed for: powerful, energy-efficient, and reliable cooling when the demand was at its peak.
