Highest cooling capacity of 27 kW and heating capacity up to 36 kW
Best cooling capacity and best heating capacity: PRESTO W92 are the most powerful systems offering the most modern temperature control technology. Environmental conditions can be simulated or vacuum chambers can be kept at defined temperatures (space conditions). The W92 systems always provide sufficient power.
Performance data depends on the mains voltage in the country of use. Please select:
