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.
Benefit
Efficient
- Extremely high efficiency (COP) of all chillers.
- Efficient capacity control of the chillers depending on the temperatures in the Zortström.
- Sliding layer space optimizes running times.
- High-efficiency pumps run with minimal power consumption and don't rock each other.
Simple
- Uncomplicated, clear hydraulics despite a wide variety of load and operating conditions.
- Simple network of Zortström centers.
Safe
- The exact temperatures required are available in the Zortström centers at all times.
- Transparent control increases operational safety.
