11 kW cooling capacity for dynamic temperature changes down to -91 °C
Best heating performance combined with high cooling capacity – those are the key features of the W91 systems. These models are just as ready for embedding into pilot plants as they are for use in material and component testing.
Performance data depends on the mains voltage in the country of use. Please select:
