Roots MVR steam compressor is commonly used for compressing water vapor in MVR (Mechanical Vapor Recompression) evaporation systems.  The secondary steam generated in the MVR evaporator is compressed by the Roots-type steam compressor, increasing its pressure, temperature, and enthalpy. This compressed steam is then sent to the evaporator’s heating chamber as heating steam, maintaining the liquid in a boiling state, while the heating steam itself condenses into water. In this way, the steam that would otherwise be wasted is fully utilized, recovering latent heat, improving thermal efficiency, reducing the need for external heating and cooling resources, lowering energy consumption, and reducing pollution.

Features:

1. Wide range of airflow and pressure increase, making the product suitable for a wide range of applications, allowing users to select the appropriate compressor.
2. The compressor and motor can be connected using various transmission methods, ensuring smooth operation, simple structure, and convenient maintenance;
3. The impeller adopts a new profile, providing good sealing and high energy efficiency;
4. High product processing accuracy, reliable operation, and long service life;
5. No lubrication is required inside the casing; the design ensures that lubricating oil and the conveyed steam do not mix;
6. The compressor shaft seal uses a cartridge-type double-face mechanical seal, providing excellent sealing and ensuring zero leakage of the conveyed steam;

Why has the Roots MVR steam compressor become the “gold standard” for industrial energy conservation worldwide?

The Roots MVR steam compressor is not simply an upgrade of traditional compression equipment, but a revolutionary innovation that integrates the principles of the Roots blower with MVR technology. Its marketing advantages far surpass those of competitors (such as centrifugal or screw compressors), especially in terms of overwhelming superiority in energy efficiency, reliability, and cost-effectiveness.

1. Extreme Energy Efficiency: 60-80% reduction in energy costs, with a return on investment (ROI) as fast as 12-18 months.
Technical Principle: The MVR system recovers the low-temperature steam generated during evaporation, pressurizes and heats it using a Roots compressor, and then recycles it, replacing the new steam input of a traditional boiler. The Roots design achieves an efficiency of over 85% under low pressure ratio (1.2-2.5) conditions, far exceeding the 65-70% of centrifugal compressors.

A dairy plant with a daily whey processing capacity of 50 tons saw its annual steam consumption decrease from 12,000 tons to 2,400 tons after installing a Roots-type MVR, directly saving over 280,000 euros in energy costs (based on the average European industrial steam price of 35 euros per ton). The payback period was shortened to 14 months, significantly lower than the industry average of 24 months. For every 1kW of electricity input, 5-7kW of heat energy can be recovered, alleviating concerns about energy price fluctuations.

2. Full-condition adaptability: One machine covers multiple industries, with a customization response rate of up to 95%. Roots compressors have no surge risk in low-flow (50-10,000 m³/h) and low-pressure ratio scenarios, seamlessly adapting to food concentration (e.g., tomato sauce), wastewater treatment (e.g., electroplating wastewater recovery), and pharmaceutical crystallization (e.g., antibiotic purification). The modular design supports rapid integration into existing systems.

A German pharmaceutical company, which previously needed to purchase three sets of dedicated equipment, met GMP sterility requirements by simply adjusting the impeller clearance and material (such as Hastelloy C276) after switching to a Roots-type MVR, reducing equipment investment by 40%.

3. Significant Carbon Reduction Capabilities: Easily Meeting EU CBAM and Global ESG Goals

MVR technology reduces carbon emissions from the evaporation process by 70-90% (UNIDO data). The high efficiency of the Roots-type system further reduces grid dependence; a single 500kW unit reduces carbon emissions by approximately 1,200 tons of CO₂ annually, equivalent to planting 65,000 trees.

After the implementation of the EU Carbon Border Adjustment Mechanism (CBAM) in 2023, a Brazilian juice exporter to Europe avoided a carbon tariff of 180 USD/ton by adopting a Roots-type MVR, saving over 90,000 USD annually. Simultaneously, its ESG rating jumped from B+ to A, and it received a 1.5% interest rate reduction on green loans.
