APP high-pressure pump

Danfoss APP pumps offer compact, reliable RO desalination and water reuse with up to 92% efficiency and low total cost of ownership.

Danfoss's APP pump sets the standard for reliable, energy-efficient RO in water reuse and desalination at a low total cost. Its simple design ensures easy maintenance and long service intervals, consistently operating at up to 92% efficiency regardless of flow and pressure. Small, compact, and easily run in parallel for larger flow, the APP pump is a versatile and cost-effective solution that requires little space.

iSave isobaric energy recovery device

Danfoss iSave 3-in-1 active ERD delivers up to 94% efficiency, cutting energy and maintenance across SWRO and water reuse plants.

The iSave is a 3-in-1 active isobaric ERD which can be used to save energy and maintenance in containerized, marine, and land-based SWRO plants as well as in land-based wastewater/water reuse plants. It is optimized to recover 60% of waste energy for reverse osmosis (RO) plants of a capacity between 200 and 3000 m³ per day. iSave has an energy efficiency of up to 94%.

Gen-Save energy recovery solution

Gen-Save integrates ERD and flow control, recovering up to 80% waste energy for high-TDS RO applications without stream mixing.

Danfoss's Gen-Save is an advanced energy recovery solution with an integrated control valve functionality. It generates electricity from the reject concentrate stream while precisely managing flow and pressure. This recovered energy, up to 80% of waste, is fed back to the HPP pump, slashing net energy consumption. It is ideal for high TDS RO applications where preventing the mixing of reject and feed streams is crucial.

APP high-pressure pump with ceramics

Danfoss APP pumps offer oil-free, water-lubricated RO operation with up to 92% efficiency—ideal for critical ZLD/MLD applications.

Danfoss's award-winning APP high-pressure pumps set the standard for reliable, energy-efficient RO. With durable ceramic components, they achieve up to 92% efficiency, ensuring low total cost. The oil-free, water-lubricated axial piston design offers stable flow, long life, and prevents contamination. Compact and lightweight, these pumps are ideal for easy integration in critical ZLD/MLD applications, protecting membranes and minimizing maintenance.

MPE 70 energy recovery device

MPE 70 isobaric ERD delivers up to 94% efficiency, recovering 60% waste energy in large SWRO systems (>3,000 m³/day).

The MPE 70 is an active isobaric ERD which can be used to save energy and maintenance in containerized, marine, and land-based SWRO plants. It is optimized to recover 60% of waste energy for reverse osmosis (RO) plants of a capacity above 3000 m³ per day. MPE 70 has an energy efficiency of up to 94%.
