Page 15: Proper Use
The EC Tower is designed for removing high heat loads from 150 to 700 W/m² from small and medium-sized equipment rooms. Any other use beyond the above is regarded as improper use. Stulz cannot be held liable for damage resulting from such use. The plant operator is the sole bearer of this risk.
