solvent recovery systems (SRU | SRS | SRP) for helio printing industries
Solvent Recovery Units (DEC.SRU™), also known as Solvent Recovery Systems (SRS) or Solvent Recovery Plants (SRP), are devices used to recover solvents from air emissions of helio printing industries.
Heliogravure, also known as helio printing, is a high-quality printing process used for reproducing images with fine details and tonal range. It is a form of intaglio printing that uses a copperplate or a cylinder engraved with small cells or dots of varying depths. The process involves transferring ink from these cells onto the printing substrate.
Heliogravure printing is often used for producing high-quality art prints, fine art photography, and limited edition books. It offers excellent image fidelity, sharpness, and tonal gradation, making it a preferred choice for reproducing intricate or complex artworks. However, the process is more time-consuming and requires specialized equipment and expertise compared to other printing methods.
The process has evolved over time, and similar techniques are now often referred to as rotogravure printing or intaglio printing.
Solvent Recovery Units (SRU | SRS | SRP) dedicated to helio printing industries are the best solution to reduce solvent emissions (VOCs) in a sustainable way: no oxidation, no CO2 (DECarbonization).
The solvent is recovered, for direct reuse, at a fraction of its purchase cost and with a purity even higher than the fresh virgin solvent.

SLA (Solvent Laden Air) is pushed by the fans through a multi-adsorber (activated carbon) system, to allow a high efficiency VOC (Volatile Organic Compounds) capture.
Once the adsorbent is saturated (automatically monitored by a VOC analyzer), the system is automatically cleansing the adsorbent, through an on-site regeneration cycle. The system is using a combination of exclusive processes, allowing the direct recovery of the anhydrous solvent.
