Its modular, limitless scalable design supports future expansion, effortlessly scaling solvent recovery capacity from 20,000 to 300,000 m³/hour to accommodate business growth. Perfect for solvent-intensive printing operations (rotogravure, lamniation, coating, flexo, etc.), this technology ensures sustainable, budget-friendly solvent reuse while prioritizing quick implementation and long-term adaptability.

a sustainable technology and process • DEC.SRU-SMS™
Solvent Recovery Units (SRUs) are VOC emission control systems offering a sustainable solution by significantly reducing harmful air pollution while conserving valuable resources. By capturing and reusing solvents in the process, these systems minimize direct and indirect pollution (decarbonization), lowering costs, while improving overall environmental performance and contributing towards your sustainability goals.

the MBC™ | MONOBLOC™ RSV™ series • DEC.SRU-SMS™
Introduced in the 1970s, the MONOBLOC™ series represented a revolutionary shift in Air Pollution Control technology; this design integrated multiple activated carbon adsorbers into a single vessel. This engineering breakthrough allowed DEC to deliver a complete Solvent Recovery Unit within one single shipment, which significantly reduced installation time and onsite complexity. The MBC series was specifically engineered to meet the stringent requirements of the pharmaceutical and chemical industries; it provided a compact and efficient solution for the Customer to manage emissions while recovering valuable resources. A MONOBLOC_RSV™ unit is a single-chassis, "plug and play" system where all primary components of the recovery process are contained within one structural frame.

the MBC™ | MONOBLOC™ RSG™ series • DEC.SRU-SMS™
The MONOBLOC_RSG™ series, introduced by DEC in the late 1980s, represents a significant milestone in the evolution of MONOBLOC™ Solvent Recovery Units (SRU). This specific engineering design focuses on the integration of nitrogen-regenerated (inert gas) adsorption technology into a streamlined, high-efficiency format. The MBC_RSG™ series shifted the industry standard by integrating multiple activated carbon adsorbers into a single, linear structural frame. This configuration provides a complete APC solution for small to medium-sized emission sources; it also serves as a modular "add-on" to existing SRUs when production increases require additional flow treatment without a full plant redesign or retrofit. This architecture is particularly effective for the DEC.RSG™ (Inert Gas Regeneration) process. By using nitrogen to recover solvents in a water-free environment, the BUYER prevents the degradation of sensitive chemicals, such as Esters or Ketones.

the DXX™ | RSG™ series • DEC.SRU-SMS™
The DXX_RSG™ series, introduced in the late 2010s, represents the latest chapter in this evolving modular design strategy. This advanced configuration expands the capabilities of the legacy established by previous series; it effectively scales to accommodate larger industrial requirements. Thanks to a series of pre-engineered modules that can be arranged in different, limitless configurations, the Customer can select the setup that best meets his needs. By utilizing the DXX™ series, industrial facilities ensure long-term compliance with environmental regulations while maximizing the return on investment through resource recovery. The modular nature of the system allows for future expansions without the need for a full plant redesign.

Indoor Installation • DEC.SRU-SMS™
The compact modular approach allows for the SRU to be installed indoor, a solution that was previously challenging due significant space constraints. This design strategy utilizes vertical space and optimized footprints to integrate seamlessly into existing industrial buildings, ensuring that the Customer can maximize their available floor area. The indoor layout is mainly driven by visual impact or extreme weather protection, especially in regions prone to heavy snowfalls and extreme low temperatures. By housing the SRU inside, the Customer protects sensitive instrumentation and mechanical components from thermal stress and moisture, which reduces the need for extensive heat tracing and specialized insulation. This arrangement ensures consistent process performance and simplifies maintenance activities during harsh winter conditions, provided that the building ventilation and safety protocols are strictly followed.

Platform-Based Installation • DEC.SRU-SMS™
The innovative modular approach allows for the SRU to be located on a steel platform (single or multi-level), a solution that was previously challenging due to size and weight constraints. The DEC.SRU-SMS™ platform is specifically designed to be compact and lightweight, enabling it to be placed in locations that are not feasible for traditional DEC.SRU_CBS™ • Custom Built Systems. This flexibility is a game-changer for industries with limited floor space or those that require a more mobile or adaptable setup.
