Tunnel Freezer Construction Services in Nairobi, Kenya
Meta description: Expert tunnel freezer construction in Nairobi, Kenya by Refitec Kenya. Custom-built tunnel freezers for IQF and blast freezing of food products. Call +254 704 843 613.
The tunnel freezer is one of the most versatile and proven freezing systems in the food industry. Products travel on a conveyor through an insulated tunnel where high-velocity cold air freezes them rapidly and evenly. Refitec Kenya offers complete tunnel freezer construction services in Nairobi and across Kenya, building custom freezing tunnels that match each client’s product, capacity, and facility layout.
What Is a Tunnel Freezer?
A tunnel freezer consists of an insulated enclosure, a conveyor system that carries product from the inlet to the outlet, powerful fans that drive refrigerated air across the product, and evaporators that maintain the tunnel at extremely low temperatures, typically between minus thirty and minus forty degrees Celsius. Products enter at ambient or chilled temperature and emerge fully frozen within minutes.
Tunnel freezers can operate in several modes. As blast freezers, they freeze cartons and bulk products. As individually quick frozen, or IQF, systems, they freeze loose pieces such as berries, vegetable cuts, prawns, and diced fruit so that each piece remains separate. The flexibility to handle both formats makes the tunnel freezer a cornerstone of many processing plants.
Advantages of Tunnel Freezing
- Uniform freezing: consistent air distribution ensures every product receives the same treatment.
- High capacity: continuous or batch operation supports large production volumes.
- Product flexibility: one tunnel can handle different products with simple adjustments.
- IQF quality: loose products freeze individually, allowing consumers to pour exactly what they need.
- Hygienic design: smooth stainless surfaces and accessible conveyors allow thorough cleaning.
Our Tunnel Freezer Construction Services
Design and Engineering
Construction begins with design. We establish your product characteristics, required freezing time, throughput, inlet temperature, and target core temperature. We then size the refrigeration load, select the conveyor type and length, design the airflow pattern, and plan the insulation panels, doors, and drainage to suit your building.
Panel Construction
We construct the tunnel enclosure from insulated panels with continuous gasket seals, minimizing heat ingress and frost formation. Doors are fitted with safety releases, and the enclosure is engineered for efficient defrosting and cleaning.
Refrigeration and Conveyor Installation
Our technicians install the evaporators, fans, condensing units, and refrigerant piping, together with the conveyor drive, belt, and tracking systems. Electrical and control wiring follows, including temperature sensors, interlocks, and operator panels.
Testing and Commissioning
Before handover, we test the tunnel at full production load, verify that products reach the required core temperature, check air velocities and temperatures throughout the tunnel, and train your operators and cleaning staff. Commissioning documentation confirms performance for your records and for export certification purposes.
Maintenance Support
Refitec Kenya maintains constructed tunnels with scheduled services covering defrost systems, belt inspection, evaporator cleaning, refrigeration performance checks, and controls calibration, plus rapid breakdown response using genuine spare parts.
