MVR (Mechanical Vapor Recompression) refers to the process of compressing the secondary steam from evaporation, distillation, and other processes again with a compressor, increasing the enthalpy of the compressed secondary steam, and reheating the materials that need to be evaporated as a heat source, thereby achieving the goal of recycling steam and eliminating the need for additional steam supplementation during the evaporation process; A high-efficiency energy recycling and energy-saving evaporation technology that uses a small amount of electrical energy to obtain more thermal energy, thereby reducing the system's demand for external energy.

TVR (Thermal Vapor Recompression) refers to an efficient energy-saving evaporation technology that compresses the secondary steam generated by a one effect evaporator using a heat pump to increase the enthalpy of the compressed secondary steam, and then uses it as a heat source to reheat the materials that need to be evaporated, thereby achieving the goal of recycling steam and reducing the need for external energy in the system by supplementing steam during the evaporation process.

A multi effect evaporation system mainly consists of multiple evaporators, each working at different temperatures and pressures to achieve cascade utilization of heat energy and improve the thermal efficiency of the entire system.
