What CLIMATELEC does

CLIMATELEC is a French thermal and industrial engineering company founded in 1984, operating as a subsidiary of Dalkia (EDF Group) since 1992. The company provides turnkey design, engineering, and installation services for district heating networks, industrial utility systems, and energy recovery projects. It operates from 8 regional offices across France (Contres-en-Sologne headquarters plus Tours, Cesson Sévigné, Saint Herblain, Guipavas, Saran, Mérignac, and Bezons) and employs approximately 130 people, generating annual revenue of approximately €50 million. Its customer base spans French municipalities and intermunicipal authorities (Orléans Métropole, Montargis, Syner'gie Le Mans Métropole, Grand Paris Sud) and industrial manufacturers (Tata Steel, ArcelorMittal, Renault, EDF, Galliance, Armor, Trelleborg), with project work frequently executed through Dalkia's commercial network as the parent company is also the main contractor.

The company's core proprietary asset is the Climaskid, a prefabricated skid-mounted district heating sub-station manufactured in-house at the Contres workshop since 2016, with more than 700 units produced to date. Climaskid units range from 100 to 1000 kW and integrate SWEP brazed plate heat exchangers, SAMSON control valves, KAMSTRUP ultrasonic energy meters, and SOFFREL communicating regulators with GSM capability. CLIMATELEC complements this with internal 3D engineering (AUTOCAD and REVIT), prefabrication workshops equipped with overhead cranes and fabrication machinery, a mobile 1.2 MW gas boiler plant for emergency or supplementary heating, and two-stage hydraulic accumulation systems capable of operation from 400 kW to 18 MW. Specialized capabilities include ISO 9606-1 certified welders for high-pressure work, multi-utility distribution systems, and energy audit and diagnostic services. The company holds Qualifelec MGTI3 (with automation, control and measurement, and study and design mentions), Qualigaz collective heating, APSAD D19 thermography, PCB prefectural approval, and Category 1 refrigerant handling certifications.

CLIMATELEC monetizes through project-based turnkey contracts awarded via competitive public tendering for municipalities and direct negotiation for industrial clients. Pricing is quote-based with no public pricing list, and contracts are typically multi-year. The company also generates follow-on revenue through maintenance, repair, and the rental of its mobile boiler fleet for emergency and supplementary heating. As an integrated contractor covering the full value chain from conception to commissioning, it provides single-point accountability for complex thermal and industrial projects, with technical expertise and regulatory compliance serving as key differentiators in public procurement.

Core offering

Climatelec is a French thermal and industrial engineering contractor that designs, builds, and commissions district heating networks, biomass and geothermal energy installations, industrial utilities (compressed air, steam, chilled water, hot water), and industrial process piping for municipalities and industrial clients. The company manufactures its proprietary Climaskid prefabricated district heating sub-stations in-house at its Contres workshops and delivers turnkey projects from initial study through commissioning.

Product overview

CLIMATELEC is a thermal and industrial engineering services company, not a software product company. It offers a comprehensive portfolio of integrated services under the broader Dalkia/EDF group umbrella. The core offerings include Valorisation Energétique (energy recovery/valorization), Production et Réseaux de Chaleur (heat production and district heating networks), and Climaskid (pre-fabricated underground heating substations). These are complemented by specialized services in industrial piping and process systems (Tuyauteries Industrielles & Process), air treatment (Traitement d'air et d'ambiance), utilities production (Production d'Utilités), low-current automation (Courants Faibles - Automatisme - Mise en service), turnkey design and construction (Conception et réalisation clé en main), and technical expertise (Etude, diagnostic et expertise). The company also offers a mobile boiler service (Chaufferie mobile) for emergency or supplementary heating needs.
