Explosion Proof MVR Steam Compressor 7T/H 2 Stage Centrifugal Compressor
A fully lubricated explosion-proof two-stage steam compressor specially customized for the 7T/H MVR system of lithium battery chemical plants. This advanced system features a special bearing system with silicon nitride ceramic rolling elements and Hastelloy inner and outer rings, capable of withstanding strong corrosive media such as LiPF₆, NMP, and ammonia.
Performance Specifications:
• Maintains vibration ≤ 4mm/s and low-noise operation ≤ 65 dB(A) at working temperatures up to 90℃
• Integrated dual head oil mist constant pressure lubrication architecture
• Zero water vapor infiltration and zero electrical corrosion damage in bearing chamber
• Lifespan exceeding 26,000 hours
• Matched with 250-350 kW high-power motors
• Compression ratio: 1.8-2.3
• Temperature rise: 18-22℃
• Unit evaporation energy consumption as low as 20-40 kWh/t water
Compliant with Ex d IIB T4 Ga explosion-proof standards and GB 3836.1-2024 specifications. Successfully deployed in supply chain MVR evaporation units, supporting modular quick disassembly, remote vibration monitoring, and 7×24-hour localized operation and maintenance. The ultimate power core for safety, longevity, and zero leakage in high corrosion, high-speed, and heavy-duty ammonia recovery scenarios.
Centrifugal compression is the best choice for MVR systems used in processes such as evaporation crystallization, concentration, temperature and pressure increase.

| Parameter | Single Effect Evaporator | Multi-effect Evaporator | MVR Evaporator |
|---|---|---|---|
| Energy Consumption | High energy consumption, theoretically 1 ton of steam required to evaporate 1 ton of water | More energy-efficient, energy consumption decreases as efficiency increases | The most energy-efficient technology, requires only 15-50 kWh of electricity per ton of water |
| Floor Area | Small | Large | Small |
| Impact on Product Quality | Short dwell time, but high temperature, minimal impact on product quality | Long dwell time, high temperature, minimal impact on product quality | Short residence time, evaporation due to temperature difference, minimal impact on product quality |
| Energy Mode | Requires steam heating, steam pipeline network and boiler | Requires steam heating, steam pipeline network and boiler | Electricity only, no steam pipe network required, fully self-closing circulation system |
| Operating Cost | High | Higher | Low |
| Stability | Poor | Poor | Good |
Key Advantages: Compared to other evaporator types, MVR evaporators offer the lowest energy consumption, smallest footprint, minimal impact on product quality, simple control system, and high stability.
