About us

Engineering with real plant-floor experience.

LOEN Ingeniería is the technical brand of LOENTEC SL, an industrial mechanical engineering company based in Jerez de la Frontera.

Industrial zinc washing and refining plant, designed and documented by LOEN Ingeniería

We turn industrial needs into engineering that can be executed.

LOEN Ingeniería combines over 15 years of real experience in industry (machinery, structures, mechanisms, capital equipment, manufacturing and assembly) to deliver solutions the workshop can build and the company can profit from.

When you have a project, a machine, a structure or a technical problem to develop, we bring the engineering capability to turn it into designs, calculations and documentation ready for manufacture. Close to the client, close to the workshop and close to the realities of fabrication.

Our portfolio spans mining, water treatment and logistics projects: thickeners, tanks, chutes, pump boxes, platforms and complete plants. Many of these are now manufactured and operating.

You can see a selection of this equipment — thickeners, chutes, pump boxes, complete plants — on our projects page.

Who's behind it

You speak with the person who designs.

LOEN isn't a call centre or a chain of intermediaries. When you get in touch, you deal directly with the engineer who will develop and oversee your project.

LOEN is led by Daniel López, a mechanical engineer with over 15 years of experience in industrial sites: design of machinery, structures, mechanisms and process equipment for sectors such as mining, water treatment and logistics. Experience gained on the plant floor, not just on a computer screen.

That means direct communication, technical decisions backed by sound judgement, and a single point of contact who knows your project from start to finish: from the first sketch to resolving doubts on the workshop floor.

How we work

We propose, and review it with you.

We don't hand over a fixed solution on day one. We study the problem, propose an approach and validate it with you. The solution is refined step by step (technically and financially) until it's right.

01

We study

We understand the problem, the constraints and what the company really needs before proposing anything.

02

We propose, and review it with you

We validate every step with the company. The solution is refined until it's right, both technically and financially.

03

We deliver something manufacturable

Clear, complete documentation so the workshop can build it on budget and without doubts.

How we understand engineering

Three principles that guide every project.

Designing for manufacture

A design is only good if the workshop can build it on budget and without improvising. Manufacturability guides every decision.

Reducing risk

We calculate, validate and document our assumptions, so the client can decide and manufacture with less uncertainty.

Clear technical communication

We explain what we do, why, and on what basis. No grandstanding, no small print.

Sectors
