Sustainability is a built-in part of our strategy.
CTI’s entire business is built on promoting cleaner energy. All of our solutions – from electric boilers to retrofit projects and battery systems – are aimed at delivering concrete emission reductions, improving energy efficiency, and supporting smart resource use. We don’t treat sustainability as a separate effort – our work is sustainability.
We are a partner that takes full responsibility for the technical whole – not just individual components. All solutions are designed and documented in accordance with EU standards. For example, our electric boilers are manufactured according to European pressure equipment standards, and system safety is ensured both electrically and through commissioning tests.
In addition, we support our customers in identifying funding and subsidy opportunities, making investments in green technology economically viable as well.
We deliver solutions that enable our customers to:
- Transition to fossil-free fuels
- Participate in electricity grid balancing markets
- Extend equipment lifecycle through modernisation
- Integrate traceable emissions data into ESG reporting
