M / MAXIMS

Four engineering
principles.

Notes from the title block of every Eirich drawing sheet. They describe how the company works, not what it sells.

01

Measure, do not assume.

Every recipe begins on a real Eirich machine in Hardheim. No simulations stand in for a measured protocol.

02

Scale the drawing, not the principle.

From 0.1 litre to 12,000 litre, the geometry stays the same. Only the dimensions change.

03

Own the lifecycle.

Eirich engineers, builds, commissions and services the machines and the plants around them.

04

Speak the operator's language.

Documentation, support and training in six languages, from Hardheim to the customer's site.

The Hardheim Technikum has been running customer trials since 1972. The next slot is for your sample.
