Bachem AG, Bubendorf, CH

Project focus

Construction of maximum storage capacities for specific storage classes (e.g. acids, alkalis) and storage conditions (e.g. cooling area) in the central area of the company premises


Automated high-bay warehouse for solids (468 pallet spaces, double-deep transverse storage) and for liquids (260 spaces for palletized and non-palletized IBC containers) in EX-protected design, with MASTer storage and retrieval machines and logOS Software Suite


Proper handling of pharmaceutical precursors and active ingredients optimized from a safety perspective


Fire protection installations with sprinklers and three fire protection high-speed doors with emergency power battery pack, which are the first to close in a controlled manner in the event of a gas or fire alarm in the EX area

Excellent - Intelligent - Fire-protected

Reliable handling - in compliance with guidelines

The Bachem Group is a listed technology company specializing in peptide chemistry. The focus is on the development of innovative, efficient manufacturing processes and the production of peptide-based active pharmaceutical ingredients. In order to store, quarantine, release and safely move a maximum number of products in a minimum of space and in accordance with qualified pharmaceutical guidelines, Bachem and Stoecklin have decided to divide their storage capacities into two.

The new high-bay warehouse supports our growth strategy and will help us to further expand our leading global position in the peptide market.

Exactly the right solution

A MASTer-18T pallet stacker crane, which is designed for double-deep transverse storage and serves 468 storage locations, moves over a length of 20.4 m in the automated solids warehouse. A single-motor 2-prong telescopic fork ensures that the pallets can be stored on top-hat profiles to save space. The 17.7 m high storage and retrieval machine (SRM) is designed for load capacities of up to 600 kg.

The 260 pallet storage locations in the liquid storage area, where more critical goods are stored, are accessed by a 17.7 m high MASTer 24-DT storage and retrieval machine designed for loads of up to 1,400 kg. The fixed 2-prong telescopic fork for single-deep storage can convey IBC containers with and without sub-palletizing.

The handling rate for both systems is an average of 30 pallets per hour - for twelve hours, five days a week.

Machine, explosion protection and EMC directive

The system in the liquid storage facility was designed in accordance with the provisions of the Machinery Directive (2006/42/EC), the Explosion Protection Directive (2014/34/EU) and the EMC Directive (2014/30/EU): The storage and retrieval machine was designed in EX protection zone 2 in the floor area, with a design in accordance with temperature class 4. Drives, sensors and profile control in the pre-zone of the high-bay warehouse were/are also EX-protected from the floor to a height of 1 m. Many other electrical components were installed above the EX protection zone for safety reasons.
