Advanced heat transfer technologies engineered to meet rigorous EU industrial standards and local Catalan environmental mandates.
The Metropolitan Area of Barcelona and the wider Catalonia region constitute one of Southern Europe’s most critical industrial hubs. With prominent sectors spanning chemical synthesis, pharmaceuticals, food processing (especially in the Lleida and Girona sub-regions), and heavy metallurgy, the demand for high-performance evaporation technology has intensified. Catalan industries are facing double pressures: complying with the strict environmental mandates of the Catalan Water Agency (Agència Catalana de l'Aigua - ACA) and meeting Europe's ambitious 2050 carbon neutrality targets.
Industrial evaporators are no longer viewed merely as process tools; they are the heart of energy decarbonization and Zero Liquid Discharge (ZLD) systems. By employing advanced mechanical vapor recompression and waste heat utilization frameworks, manufacturers in Barcelona can convert complex wastewater streams into clean, reusable condensate while recovering valuable by-products (such as salts, organic raw materials, and proteins) that were previously discarded.
MVR reduces steam consumption by re-compressing the secondary vapor, saving up to 80% operating cost compared to multi-effect designs.
Conforms to EU green deal directives for water circularity, recovering over 95% of purified process water for factory reuse.
Utilization of duplex steel, Titanium Grade 2, and Hastelloy materials prevents mechanical failure under extreme chloride and acidic conditions.
Spain, particularly Catalonia, has experienced severe drought challenges, making water scarcity a top-tier operational risk for chemical and manufacturing plants. Regulatory authorities have placed strict limits on industrial discharges into the municipal sewage grid and natural water basins. Evaporation systems developed by Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd. address this regional pain point directly. Our technologies help factories close their water cycles, eliminating liquid waste output and ensuring uninterrupted operation even during regional water restriction events.
Designing an evaporator system requires a precise understanding of the feed liquid’s boiling point elevation (BPE), viscosity changes, and fouling tendencies. Standard, out-of-the-box machinery cannot withstand the volatile parameters of chemical processing. As an engineering-first manufacturer, our design philosophy incorporates rigorous laboratory analysis of the raw liquid before determining the technology route.
Uses a centrifugal fan or turbo compressor to increase the energy level of the evaporated vapor, returning it to the heating chamber to eliminate the need for fresh boiler steam.
Ideal for thermal-sensitive chemical compounds, offering thin-film downward distribution inside vertical tubes, maintaining low hold-up times and dynamic heat transfer coefficients.
Combines a recirculation pump, vertical/horizontal heat exchanger, and separator to drive fast-velocity liquid flows, allowing high-salinity solutions to reach saturation without scaling the tubes.
Captures low-temperature flashing steam from dry-cooling, venting systems, or furnace exhaust, routing it through successive negative-pressure effects to maximize energy efficiency.
