High-level technicians with extensive experience in the construction, assembly and maintenance of complex industrial units. COTRAC operates on a fixed-price or hourly basis, with the ability to mobilise quickly across Senegal and West Africa.
Ten complementary technical specialities to cover all industrial engineering, HVAC, insulation and refrigeration needs.
Installation and commissioning of industrial mechanical equipment: belt and chain conveyors, bucket elevators, gravimetric and volumetric feeders, screw conveyors. Complete industrial maintenance: electric motors (rewinding, replacement), reducers, couplings, centrifugal and volumetric pumps. Periodic monitoring with maintenance sheets and intervention reports.
Study, fabrication and assembly of industrial steel structures (warehouses, workshops, walkways, conveyor structures). Boilermaking work (tanks, reservoirs, hoppers), industrial piping with high-pressure (HP) welding in carbon steel and stainless steel. Complete turnkey industrial unit installation.
Thermal insulation with rock wool on steam lines, exhaust pipes and generators - reducing heat loss and protecting personnel. Hot water line insulation with injected polyurethane foam under galvanised steel, stainless steel or aluminium cladding. Neat, weather-resistant finishes.
Injection of rigid polyurethane foam (P.U.R) under galvanised steel, aluminium or stainless steel cladding for cryogenic and refrigeration installations. Key references: ICS MBAO - insulation of liquid ammonia storage spheres. Construction of freezing tunnels at -40°C and cold storage holds at -18°C / -20°C for the food and fishing industry.
Workshop fabrication of galvanised steel ducts 0.6 to 1.5 mm thick, production capacity of 1 tonne per day. Spiral ducts from 1 to 6 metres in diameter. Professional kitchen extraction systems (restaurants, hotels, institutions): filter hoods, ducts, centrifugal fans and flow control. Double-flow ventilation networks and humidity-controlled HVAC.
Small refrigeration units with PUR panels, galvanised steel on both faces, INDUSTRIAL type up to 4 metres high, 200 mm thick. Large refrigeration units with ISOCAB panels spanning up to 12 metres without intermediate support. Turnkey installations including condensing unit, evaporators, control panel and temperature alarms.
Supply and installation of positive pivot doors with 80–120 mm insulation, standard opening 1.90 × 0.90 m, FERMOD approved closures. Negative doors (enclosures at -20°C) fitted with anti-frost heating elements on seal and threshold. PVC strip curtains for access airlocks and high-traffic passages.
Fabrication and installation of "cold" profiles in 0.6, 0.8 and 1.0 mm galvanised steel. Insulating PUR false ceilings 20 mm, double aluminium face in formats 60×60, 120×120 and 200×120 cm for agri-food production zones, laboratories and kitchens. Acoustic false ceilings 60×60 mm for offices, meeting rooms and commercial spaces.
Design and fabrication of custom Sorbonne-type laboratory fume hoods in stainless steel or polyester. Stainless steel sheet metal work with argon welding (TIG) for impeccable surface quality. Fabrication of kitchen equipment for institutions (worktops, sinks, shelves, stainless steel cabinets). HACCP compliance for agri-food installations.
COTRAC is the exclusive representative for West Africa of the Italian brand PITRE. P3 panels in PUR foam with natural varnished aluminium on both faces for recording studios, radio/TV studios, clean rooms. Flagship application: recording studio at Dakar Airport.
Preventive and corrective maintenance contracts for industrial equipment: electric motors (rewinding), reducers, couplings, centrifugal and volumetric pumps. Standardised maintenance sheets and intervention reports with full traceability.
Fabrication and installation of industrial piping networks in carbon steel and stainless steel with high-pressure (HP) welding. Tanks, vessels, hoppers, retention basins. Radiographic inspection and hydrostatic testing. Compliance with ASME and EN 13480 codes.
A complete tool fleet to operate independently on all types of industrial sites, without subcontracting key services.
Civil engineering work in complex industrial environments, interventions on operating sites, controlled demolitions and rehabilitation of existing structures. COTRAC adapts to the most demanding constraints.
