Replacement system

The previous chiller had reached the end of its service life and had to be replaced. A new low-noise propane chiller was installed and commissioned in record time. The backbone of the project was the long-standing partnership with the supplier of the chiller.

Bespoke cooling solutions pay off

In addition to high-quality and financially attractive standard solutions, CTA offers its customers custom refrigeration systems that meet special requirements (capacity, regulation, installation, etc.). Although they are more expensive to purchase, they often promise savings in energy costs. And it shows: despite higher investment costs, custom refrigeration solutions are not necessarily more expensive than standard machines over their entire service life.

Mini-neighbourhood heating cooperative

In a terraced house in Basel, a nano-cooperative is providing heat. This neighbourhood cooperative provides 90% of heating from renewable energy, instead of the previous 33%. This is despite the fact that gas-fired heating systems are still fitted in two of the three residential units.
