Factories & Industry
A stopped production line means losses by the hour. Planned preventive maintenance and rapid response on industrial refrigeration and cold rooms — no surprises. Contact us for a maintenance contract or emergency call-out.
Factories and production units in Morocco — from food processing in the Agadir and Casablanca zones, to chemical and pharmaceutical units, to textiles in Fès and Tangier — rely on complex industrial refrigeration and HVAC systems running 24/7. A single hour of downtime on a line can mean thousands of dirhams in direct and indirect losses (raw material wasted, operators waiting, delayed deliveries). Sengo operates from Marrakech across 9 regions and provides preventive maintenance and interventions on industrial refrigeration units, cooling towers, industrial compressors, centralised glycol systems and large-volume cold rooms. We coordinate with the internal maintenance manager and plan interventions during holidays or dedicated production windows to avoid stoppages. Our technical reports are written and detailed, ready to integrate into the quality system or internal CMMS. Sengo does not specialise in ground-up design of very large industrial installations (e.g. large-capacity NH3 ammonia systems), but manages maintenance and interventions on existing installations running on freon and HFC/HFO fluids, coordinating with specialised OEMs.
Common issues
- Cold line downtime
- Production stoppage risk
- Need for scheduled maintenance
Equipment and systems we service
Industrial chillers
Water-chilled chillers (Carrier, Trane, York, Daikin, Climaveneta) feeding production lines and factory offices. Maintenance on compressors, condensers, exchangers, chilled-water circuit, and control adjustment. Fault diagnostics using appropriate reading tools and replacement of market-available parts.
Cooling towers and heat-rejection systems
Open and closed cooling towers evacuating heat from production circuits: fan, sprayer and basin maintenance, plus water treatment to prevent corrosion and scaling. Regular maintenance essential for stable performance, especially in summer.
Industrial screw compressors
Screw and centrifugal compressors for larger installations (Bitzer, Frascold, Copeland, Refcomp): lubricant maintenance, wear checks, vibration and temperature monitoring, mechanical and electrical fault diagnostics. End-of-life part replacement coordinated with the original manufacturer.
Centralised glycol systems and large cold rooms
Centralised glycol loops feeding multiple cold rooms or packaging lines: pump maintenance, glycol concentration checks, control-valve calibration, insulation checks. Large cold rooms (>200 m³) require periodic monitoring of thermal performance and energy consumption.
Electrical cabinets and industrial regulation
Electrical cabinets for refrigeration installations, temperature and pressure sensors, control units (PLCs, OEM displays): connection checks, sensor calibration, operating parameter updates, software fault diagnostics. Coordinated with the internal automation lead when needed.
Workshop and office HVAC
Workshop HVAC (ducted systems, industrial DRV, air handling units AHU) and adjacent office HVAC: filter, exchanger, air-flow and humidity-control maintenance. Especially important in workshops with thermal constraints (packaging, coating, drying).
Regulatory context and industry standards
Factories in Morocco are subject to several frameworks that intersect with refrigeration systems: labour law requires an acceptable air-quality and temperature environment; industrial safety standards cover pressure equipment (tanks, refrigeration circuits). Food processing plants apply HACCP and are monitored by ONSSA on the cold chain. Refrigerants (R134a, R404A, R410A, R290, R1234yf) are governed by international environmental rules (Montreal Protocol, Kigali Amendment) requiring compliant handling. Plants with certified quality (ISO 9001) or environmental (ISO 14001) systems require written documentation of every maintenance intervention for audit archives. Invoicing with ICE and RC is required for every B2B transaction.
Typical interventions we see in this sector
Generic examples to show the nature of the work, with no client disclosure.
Chiller gradually losing performance
The maintenance manager notices rising chilled-water outlet temperature or rising electricity consumption. The technician checks gas charge, exchanger condition (fouling, scaling), suction/discharge pressures, cooling-circuit water quality, and regulation. Often deep condenser cleaning and water treatment restore original performance. Written report with before/after readings.
Sudden central-system stop during production
A line stops because central refrigeration emitted a fault. Top priority. The technician reviews control-system alarms, checks compressors, pressure sensors, electrical load, and protections. Quick decision between immediate repair or partial operation on a backup compressor if available, coordinated with production and maintenance. Detailed report on the cause and lasting fix.
Planned maintenance during annual shutdown
The plant is on annual shutdown (10–20 days). Sengo runs a deep maintenance programme: partial compressor disassembly, cooling-tower checks, full exchanger cleaning, testing of all sensors, updated control parameters, electrical connection checks. Intervention spans several days, with a consolidated report usable in CMMS and audits.
Upgrading an older circuit to a more compliant fluid
The plant runs an older system on a fluid now under regulatory constraint. Sengo delivers a diagnostic, a compatibility study of alternative solutions, modification of required parts, and compliant recovery of the old fluid. The work is executed in the dedicated maintenance window with a full compliance report.
Seasonality and year-round needs
Factories follow a sector-dependent seasonal pattern: food processing (fruit, vegetables, fish) peaks in harvest season (June–October depending on product). Beverages peak in summer. Others run at constant pace year-round. Refrigeration failures cluster in July–August when ambient heat loads cooling towers and condensers. Major preventive maintenance is ideally planned during annual holiday shutdowns (often August for some sectors, December for others) to allow deep interventions without production impact. Continuous-production plants require finely negotiated maintenance windows with the production manager.
Why a contract beats one-off call-outs
Industrial maintenance leaves no room for improvisation: every unplanned stop costs several times the preventive maintenance. With a contract, the maintenance budget is planned annually, periodic visits catch mechanical wear before it becomes a major failure, and intervention priority is guaranteed. Continuous coordination with internal maintenance saves significant diagnostic time since the technician knows the equipment. Written reports feed the CMMS and ISO files. Sengo offers three contract tiers designed to cover everything from a medium workshop to a plant with complex centralised installations — the choice follows a diagnostic visit and fleet assessment.
