The Explorer offers maximum cooling capacity with a minimal footprint.
High-quality components with easy access for maintenance purposes
STULZ's own control system with 7" touch display enables the STULZ Explorer to be perfectly integrated in existing systems.
By using components that are commonly found on the market, rapid availability of spare parts is guaranteed.
An end-of-line test and factory parameter setting ensures easy commissioning and cuts installation costs.
The direct evaporator minimizes refrigerant quantities and so helps conserve the environment.

Efficiency challenging the future: ErP 2018 ready
The European Regulation 5539/16. known as ErP 2018, sets the new SEPR parameters for assessing the energy efficiency of chillers. The entire Explorer range complies with the limits required by ErP 2018.
- E.E.R.: Energy Efficiency Ratio
Chiller efficiency at a certain condition.
- E.S.E.E.R.: European Seasonal Energy Efficiency Ratio
Seasonal efficiency of a chiller for comfort: ambient air from 25 to 35°C
- S.E.P.R.: Seasonal Energy Performance Ratio
Evaluates the load and temperature variations during the year,
relative to the chiller's electricity consumption.
