AT Turbocharger

Turbocharger

Perfected for High-Pressure Environments

The AT turbocharger is an efficient, versatile, and reliable solution designed with a compact footprint—no instrumentation or additional equipment is necessary. In addition, it requires minimal installation time and operator training. With the turbocharger’s completely removable and replaceable hydraulics, plant staff can quickly and inexpensively change operating conditions as needed while maintaining facility uptime.

This modular technology consists of pump and turbine volutes, a turbine nozzle and pump-side discharge diffuser. Ideal for SWRO systems, the AT Turbocharger handles flows from 11 to 375 m3/h (48 to 1,651 gpm) and pressures up to 83 bar (1,200 psi). For a centrifugal solution, the innovative volute insert technology allows systems to perform within a best efficiency range rather than at a single best efficiency point. If system conditions change, requiring a new operating point, these lightweight inserts can be removed and replaced in hours instead of days or even weeks, maximizing facility uptime.

LPT Turbocharger

LPT TurboCharger

Optimized for Low-Pressure Systems

The LPT turbocharger is a low-cost energy recovery solution that’s ideal for low-pressure systems. Like our AT Turbochargers, the LPT offers high-efficiency, long-term reliability and versatility in a compact footprint.

Designed for low-pressure applications such as multi-stage brackish reverse osmosis water treatment, this device handles pressures up to 41.4 bar (600 psi). The LPT is the ideal solution for two-stage systems where flux balancing and system optimization are desired. It can easily replace a booster pump for this service, providing equal or better performance all while requiring no electrical connections, motors, or drives.

Efficiency in one compact package

Our high-efficiency turbochargers offer high-performing energy recovery solutions in projects with smaller budgets—especially in locations where power costs are heavily subsidized or there’s a need to mitigate upfront capital spending.

Designed to last

Every Energy Recovery turbocharger consists of a single-stage turbine impeller connected to a single-stage pump impeller via a common shaft. All hydraulics are housed within the casing, with no seals required.

Backed by expert support

Easy to maintain, our turbochargers are supported by highly qualified and seasoned technical field services professionals around the clock.

How it works

The turbine impeller absorbs the hydraulic energy of the concentrate stream and converts it into mechanical energy. This energy is then transferred to the pump impeller. The impeller converts the mechanical energy back to hydraulic energy, providing an additional pressure boost to the feed stream of brackish or seawater reverse osmosis (SWRO) systems.

Frequently Asked Questions

The Energy Recovery turbocharger is designed for plug-in integration into either high-pressure seawater or low-pressure brackish reverse osmosis (RO) systems. For example, the AT model handles flows from 11 to 375 m³/h (≈1,651 gpm) at pressures from 27 to 83 bar (400–1,200 psi). Because it integrates hydraulics in a single casing, requires no external instrumentation or additional drives, installation and operator training time are minimal. The compact footprint and modular inserts (which can be swapped in hours when operating points change) help minimize downtime and simplify maintenance.

By recovering hydraulic energy from the concentrate/brine stream and re-using it to boost the RO feed, our turbochargers deliver substantial energy savings. Our turbochargers demonstrate 20–30% reductions in energy consumption in RO applications. Less power demand on the high-pressure pump means lower motor size and reduced lifetime maintenance costs.

The Energy Recovery turbocharger is designed specifically for SWRO and wastewater energy-recovery applications and offers several clear advantages over other standalone turbocharger devices. For example, it typically enables 20-30% energy savings in RO systems. It features a compact footprint, no external instrumentation or drives, and fully internal hydraulics, simplifying installation and maintenance. What differentiates our offering is its modular hydraulics (replaceable volute inserts) that maintain high efficiency even when operating conditions vary, supporting better uptime and lifecycle performance.
