High-Quality Mechanical Vapour Recompression Evaporator Manufacturers & Suppliers

Understanding Mechanical Vapour Recompression (MVR)

In modern industrial processing, thermal concentration is a critical unit operation. Traditional multi-effect evaporation systems consume massive quantities of live steam, leading to high operational costs and significant carbon emissions. Mechanical Vapour Recompression (MVR) represents a paradigm shift in thermodynamic efficiency.

The core principle of MVR technology lies in the recycling of latent heat. Instead of discarding the waste vapor generated during evaporation, the vapor is compressed using a mechanical compressor (such as a centrifugal fan or roots blower). This compression increases both the pressure and temperature of the vapor, upgrading it into high-quality heating steam. This compressed vapor is then redirected back into the heating chamber of the same evaporator to serve as the heating medium. Consequently, the system requires virtually no external live steam once the startup phase is complete, relying almost entirely on electrical energy to drive the compressor.

By shifting the primary energy source from thermal steam to electricity, MVR systems achieve a Coefficient of Performance (COP) that far exceeds conventional multi-effect evaporators. This makes MVR the technology of choice for industries aiming to reduce carbon footprints and optimize operational expenditures (OPEX).

The Chinese Supply Chain Advantage: Jiangsu Zongheng

Choosing the right manufacturer for heavy industrial equipment involves evaluating engineering capability, material supply chains, and manufacturing scale. Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd (formerly Yixing Yangxi Light Industry Machinery Factory), established in 1992, stands as a premier manufacturer in China's industrial heartland.

Located in Zhoutie Town, Yixing City, on the shores of Taihu Lake, our facility spans over 54,000 square meters, with a dedicated production workshop area exceeding 22,000 square meters. This scale allows us to handle large-scale fabrication projects in-house, ensuring complete control over manufacturing quality and lead times.

Our geographic location provides direct access to China's robust industrial supply chain. We source high-grade raw materials—including titanium, duplex stainless steels (SAF 2205, 2507), and Hastelloy—directly from top-tier domestic mills at highly competitive rates. Coupled with our advanced manufacturing processes, such as automated plasma welding and non-destructive testing (NDT), we deliver world-class pressure vessels and evaporators at a fraction of the cost of Western competitors.

Global Procurement Needs: Localization & Compliance

For multinational corporations, procuring industrial equipment from overseas requires strict adherence to local safety codes and regulatory standards. Jiangsu Zongheng has built a comprehensive compliance framework to serve global markets seamlessly.

We hold the prestigious ASME "U" Stamp authorization, certifying our capability to design and fabricate pressure vessels in accordance with the American Society of Mechanical Engineers standards. Additionally, our products carry CE Certification, meeting the essential health, safety, and environmental protection requirements of the European Economic Area (EEA).

Our engineering team is highly experienced in designing systems that comply with various regional standards, including PED (Europe), DOSH (Malaysia), MOM (Singapore), and local Chinese GB codes. We provide complete documentation packages, including material test reports (MTRs), welding procedure specifications (WPS), and NDT records, ensuring smooth customs clearance and local registration.

To support global installations, we offer remote commissioning assistance, localized engineering partnerships for on-site installation, and a rapid-response spare parts supply chain, minimizing downtime for our international clients.
