Has anyone seen Figaro?

TTM Energiprodukter was one of the suppliers in the construction of the prestigious Copenhagen Opera House Together with their reseller, the company succeeded in winning the deal and delivering 98 different shunt units so that Figaro, Susanna, the Count and all the others could celebrate without getting too hot – or too cold.
The Copenhagen Opera House covers an area of 41,000 m2, over 14 storeys (5 of them below ground), with 6 stages: one main stage allowing 1500 spectators (more would have impaired the optimal acoustics) and 5 stages for rehearsals and preparations. The orchestra pit, with space for 110 musicians, is one of the biggest in the world. The building has more than 1000 rooms and a gigantic foyer. TTM was entrusted to supply Shuntopac prefabricated shunt units to control and regulate the climate in the building’s many zones.
When the inquiry reached TTM, an extensive tender was prepared, consisting of an A4 folder chock full of documentation, diagrams and technical specifications for 98 different shunt units to control heating and cooling to around 50 different climate zones in the building. Artists, musicians, audience and service staff must all experience a comfortable temperature. What many people don’t know is that the Queen of Denmark has her very own climate zone in the Royal box, so she can control the temperature herself during performances.
For TTM’s export department, led by Ulf Wickström, the main challenge was the size of the project. Almost 100 different shunt units had to be individually adapted and designed for their position and task in the HVAC system.
In addition, the customer required that 10% of all welded joints must pass X-ray examination. Det Norske Veritas (DNV) was contracted for the X-ray examinations, which TTM then reported separately for each individual shunt unit.
TTM didn’t hold back during the tender process, demonstrating clearly what the company would bring to the project through technical support and the benefits of prefabricated shunt units. The result was that the customer chose Shuntopac, even though from the outset site-built shunt units were specified.
The customer has since revealed that the confidence developed in TTM as early as the tender stage formed the basis for the continued collaboration. And of course, TTM’s production capacity and ability to deliver on time, and Shuntopac shunt units from DN 20 to DN 200 were also positive elements.

Shuntopac was supplied from DN 20 to DN 200.
