DELCO

What DELCO does

D.E.L.CO. Srl is an Italian environmental engineering company founded in 1977 by Ing. Mario Coppo, specializing in the maintenance, safeguarding, rectification, and decontamination of industrial circulating fluids — diathermic (heat transfer), hydraulic, dielectric, and lubricating oils — for industrial plant operators. The company is headquartered in Inveruno (Milan) with an operational site in Arconate, operates as a family-owned private limited company (Srl), and employs 11-50 people. Its customer base spans the food and pharmaceutical processing, oil and gas, electrical power (utilities and transformer OEMs), concentrated solar power, and general industrial hydraulics sectors, served across Italy, France, Spain, Argentina, Mexico, USA, Colombia, Canada, India, Taiwan, and Morocco.

The technology stack rests on proprietary chemistry and patented mechanical processes developed in-house since the early 1980s. Core offerings include the DelcoTerm® fluid line (eight formulations: M 32, S Tfi, S DBT, S ODB, F 32, F 15, Solar E 15, S TRA), patented PCB decontamination technologies (ASD solvent vacuum autoclave, ODR dehalogenation, WWD water-based), the E-ZERO zero-emissions treatment system, 4th-generation mobile vacuum degassers, and supporting devices (Reverse Expansion Barrel, Liquid Guard, Loading/Unloading System, Hydraulic Fluid Grinders). D.E.L.CO. also operates an in-house laboratory (DELCO Oil Check®) providing condition-monitoring analysis aligned with US EPA 8082 and ASTM D893 standards, qualified as a Lombardy Region Center of Excellence (Questio 2011).

The business model combines sale of proprietary branded fluids (with an optional 10-year warranty conditional on bi-annual analytical checks), on-site field services (degassing, dehydration, filtration, magnetic filtration, re-additization), mobile equipment rental (including ODR decontamination units), design and construction of customized PCB decontamination plants, recurring laboratory analysis contracts, and paid technical training and consultancy. Revenue is generated primarily through direct enterprise field sales with custom quoting; distribution is augmented by commercial cooperation agreements with Plascon USA (Americas), Sharika India (India), and a joint-marketing arrangement with AIM-listed Hydrodec Group Plc (developing-country PCB markets). D.E.L.CO. holds the only Italian REACH registration for dibenzyltoluene and is a member of the Stockholm Convention's PCB Elimination Network since 2010.
