Engineer-to-order tubular (shell-and-tube) MVR evaporator with forced circulation for high-salinity, viscous, and solids-bearing streams. A mechanical vapor compressor recycles latent heat as the main duty, while tubular exchangers deliver robust heat transfer and fouling resistance. Designed for 480 V grids with fully automatic 24/7 operation.
Secondary vapor is mechanically compressed to elevate saturation temperature and reused as the heating medium. Forced-circulation loops keep tube wall shear high, protecting heat-transfer coefficients across variable chemistries.
Low-voltage integration for 480 V / 60 Hz (50–60 Hz configurable). VFD-driven compressor and pumps, soft-start, and optional AFE/harmonic filters for grid compliance. MV transformers available on request.
Wetted parts in SS316L/duplex; titanium/Hastelloy options for chloride/corrosive service. Drainable layouts, removable channel heads, CIP skid, and anti-scale dosing for long campaigns.
| Parameter | Typical Range* |
|---|---|
| Power supply | 480 V LV, 60 Hz (50–60 Hz configurable) |
| Operation | Continuous, 24/7 |
| Electric use (MVR) | ~15–40 kWh per ton of water evaporated (duty/CR dependent) |
| Shell pressure (vacuum) | ~6–25 kPa(abs), feed/ΔT dependent |
| Steam demand | Very low after start-up (backup/ancillary only) |
| Materials | SS316L / duplex; Ti/Hastelloy on request |
*Performance depends on feed salinity/viscosity, fouling tendency, compression ratio, and exchanger design.
Tubular exchangers are preferred for scaling, particulates, or erosion risk—offering higher robustness and easier mechanical cleaning.
Yes—commonly paired with RO/NF pre-concentration upstream and crystallization/solids handling downstream.
Optimized ΔT/LMTD and velocity, anti-scale dosing, scheduled CIP, and materials upgrade (e.g., Ti) for aggressive brines.
