# Linde Engineering — Process-plant engineering, proprietary technology and project delivery for gases and chemicals

> Linde Engineering is the plant-engineering and technology business of Linde plc, with roots in the German company founded by Carl von Linde in 1879. It designs and executes industrial gas, hydrogen, synthesis-gas, ammonia, petrochemical and cryogenic plants, and offers project models from technology supply and engineering through EPC. Scope varies by contract and may include Linde-operated industrial-gas assets; the profile therefore distinguishes its engineering work from the wider parent group’s gas-supply operations.

## How to select an EPC contractor

EPC means engineering, procurement and construction. Compare contractors by project technology, country, voltage level and contractual delivery scope.

## Directory methodology

This directory presents company profiles, not a scored ranking or certification. Company-wide experience may include engineering, EPCM, equipment supply and consortium roles. Confirm the exact role, current qualifications and project references with the official company before shortlisting.

## What should an EPC enquiry include?

Specify the project country, capacity, grid voltage, single-line diagram, site conditions, scope boundaries, target schedule and acceptance tests. Clarify who owns permitting, civil works, grid studies, commissioning and performance guarantees.

## Equipment enquiries submitted here go to Voltformer. Contact the listed company directly for its EPC services.
