The Ecolift XL is a larger, more powerful iteration of the standard Ecolift model, specifically engineered for demanding commercial and residential applications.
With a maximum power output of up to 4.5 kW, this hybrid lifting station reliably manages wastewater discharge even when operating against backwater pressure. The system incorporates up to two motor-driven closure mechanisms that activate solely during backwater events. Under normal operational conditions, the station remains unpowered, instead leveraging natural gravitational flow.
Installation flexibility is a key feature. The Ecolift XL accommodates both exposed mounting within buildings and underground placement within engineering chambers. Available variants support both 230V and 400V electrical connections. Single motor-driven closure configurations handle grey water exclusively, while dual motor-driven setups manage black water applications.
The modular construction enables flexible deployment across exposed, underground, and concrete-embedded scenarios. Chamber modules achieve groundwater resistance to depths reaching 3,000 mm.
Safety incorporates particularly powerful pump systems paired with up to two motor-driven closure mechanisms ensuring dependable separation between sewer systems and buildings during backwater events. Pneumatic level measurement and alarm sensors provide additional safety assurance.
Sustainability credentials were validated through competitive recognition — the product ranked among the top three innovations at the DGNB (German Society for Sustainable Building) Sustainability Challenge, demonstrating 90% reduced energy consumption relative to conventional lifting stations while maintaining heightened operational reliability.
