This year, the Great Orchestra of Christmas Charity played for children with urological and nephrological diseases. All over Poland, there were events, concerts and festivities to collect money for medical equipment. In Poznan, the stage was heated using Master heaters.
The main GOCC spot in Poznan was the stage near the Castle. Every year, numerous concerts and auctions are organised for different charities.
The MAKO company from Przezmierow was responsible for heating the stage throughout the event with mobile air heaters. Despite the changing and cold weather, they ensured that both artists and hosts on stage were kept warm and were able to encourage the audience to donate to the charity.
It was agreed, that the 12 x 12 x 8m stage with a total surface of 1152m³ would be heated with two indirect oil heaters. BV 290 models were used, with a power of 81 kW each.
When the heaters were selected the fact that stage area was not an enclosed spaces and there would be constant influx of cold air was taken into consideration.
The heaters were placed on both sides of the stage, and warm air was distributed to the stage using tubes in the side walls of the platform. This allowed warm air to be evenly spread over the whole area.
Silver tubes were also supported on special metal frames. The tubes in sidewalls among the musical equipment blended in with the rest of the stage and did not disturb its aesthetics.
During the whole GOCC finale, the outdoor temperature was between 0 and 5°C. The heaters managed to rise the temperature on the stage to approx. 10°C.
Opposite the stage, there was the so called control booth. A tent of about 6m² was heated using a smaller, 20 kW Master BV 70 heater, also equipped with a flexible tube to distribute the warm air. The tube’s outlet was located in the back wall of the tent.
The heaters were operational all day and late into the evening. Connecting the whole installation, as well as its disassembly, took as little as 30 minutes.
