Installation of a seawater heat pump system

29 October 2021
Energy transition: a growth strategy for SADE. Background In 2019, the Boulonnais Local Authority (CAB) carried out a feasibility test for the installation of an ambient loop system using seawater to produce heat. The study site is located in the port of Boulogne-sur-Mer (Capécure area). The aim of the  is to power two warehouses of the cold storage company Norfrigo, in place of the current air-cooled condensers, and thus enhance the energy efficiency of the refrigeration production unit. The study consists in the creation of two ambient heat loops: A seawater loop An intermediate industrial water loop (glycol water) The… +

DPSM demonstrates its extensive expertise

7 October 2021
From compelling conviction to technical mastery. We look back at a trenchless adventure!

A multi-network, multi-technique project for SNF, the specialist in polymers for the petrochemical sector

7 September 2021
In the wake of the COVID pandemic, SNF, the flagship of France’s chemical industry, reviewed its economic approach to polymer production. It turned to greener production, geared towards cardboard manufacturers, with new water-soluble polymers which help to reduce raw material needs. Extension works were thus carried out to its plant in Dunkirk port, with the building of a first production unit for these new polymers. The Hauts-de-France RD (Dunkirk Agency) laid the underground networks on the site, which, given the constraint of the water table, consisted in: 45,600m³ of excavation works Laying of more than 4km of stormwater network (315mm-diameter… +

A new market in Romania
