Cargill has been operating in Nicaragua since the year 2000 at Masaya. This processing plant is for human nutrition, specifically a chicken processing plant.
Operating Since
Nicaragua
Vulcan Units
Parent Company: Cargill de Nicaragua S.A., Managua, Nicaragua
Facility: Human nutrition chicken processing plant
Limescale in the cooling tubes, due to minerals present in the water and heat exchange, was reducing the capacity of the evaporative condensers and decreasing performance. Despite water softening (targeting 60 ppm) and chemical treatment with three chemicals (antiscaling, antioxidant, and algaecide), good results were not obtained.
Model: Vulcan S25
Pipe: 2-inch steel pipe
Water Capacity: 20 m³/h (88 GPM)
Location: Refilling line of the refrigeration area
Model: Vulcan S100
Pipe: 6-inch PVC pipe (DN150)
Water Capacity: 40 m³/h (176 GPM)
Location: Closed circuit of the condenser in the refrigeration area
This food processing plant installed two Vulcan models:
Installed on a 6" (DN150) PVC pipe at the closed circuit of the condenser.
Human nutrition chicken processing plant in Masaya, Nicaragua.
Four witness points were selected (portions of about 15 cm of pipe). The limescale was removed mechanically to verify if there would be re-incrustation with Vulcan during the test period.
The witness pipes remain free of new limescale.
The areas around the witness pipes show that the limescale is more fragile, proving that VULCAN is removing the old limescale, cleaning little by little.
Old layers of limescale are coming off. The formation of new limescale has stopped.
The Problem: Limescale in the cooling tubes, due to the minerals present in the water and the heat exchange. This happens in all the evaporative condensers in this area. Limescale reduces the capacity of the condenser, reducing its performance.
Previous Treatment: Water softening equipment in the engine room treats well water to reach 60 ppm hardness. Then in the condensers, three chemicals are added: antiscaling, antioxidant, and algaecide. Good results were not obtained despite these two treatments.
Test Results: Four witness points (15 cm pipe sections) had scale removed mechanically to check for re-incrustation. After 3 months:
The witness pipes remain free of new limescale.
The areas around the witness pipes show that the limescale is more fragile, proving Vulcan is removing old scale little by little.
Old layers of limescale are coming off.
Before Vulcan, the plant was using:
Water from the well was treated to reach 60 ppm hardness (expected).
Three chemicals were added to the softened water: Antiscaling, antioxidant, and algaecide.
Good results were not obtained despite both treatments. Scale continued to form, reducing condenser performance.
Even with the existing softening and chemical treatment still in place, Vulcan prevented new scale formation and began removing old scale deposits within just 3 months.
Scale-free condensers maintain cooling capacity and performance.
Potential to reduce or eliminate chemical antiscalants.
Fewer cleaning cycles mean more production time.
No chemicals added to water lines means no risk of contamination.

Cargill Nicaragua demonstrates that even with existing water softening and chemical treatment, Vulcan delivers results. Within 3 months, witness pipes remained scale-free and old deposits began breaking away—proof that Vulcan works where conventional treatments fall short.
