Cold generator



Heat and cold generated cost-effectively

The simplicity of Zortström technology guarantees cost-effective heating and cooling that is delivered to where it is needed at the right time, in the right quantity and at the lowest possible transportation costs.

Zortström runs maintenance-free

The cold comes directly from the chillers via the Zortströms to the consumer circuits. The integrated buffer in the Zortström simply neutralizes the excess cold. The activation of the chillers can be set according to the temperature curve at the buffer. Frequent switching or cycling is avoided. The control technology provides daily proof that a perfectly functioning, simple hydraulic system can still be relied on years later. This means that service costs are a thing of the past once and for all. If it says Zortström on it, it’s maintenance-free.
