Turnkey systems and complete solutions
LETZNER is delivering turnkey systems worldwide: ready-for-operation solutions from drinking water to the point of use in the clean room. The entire system, including the vessel and distribution piping, can be provided and seamlessly integrated into the facility using high quality pharmaceutical grade components. Similar to modular design, different qualities, components and technologies can be chosen in terms of material, surface structure, type and processing as required. LETZNER is committed to taking into account all customers' needs and demands, all regulatory standards and guidelines and the given composition of the feed water.
Process and product safety and thus the patient’s safety are absolutely paramount to us. To be able to ensure this safety at all times, we comply with recognized guidelines and exclusively use very high quality materials from the feed water entry to the point of use for the consumer. Our staff is dedicated to the GMP idea and implements it in all process steps and workflows. Turnkey solutions - made in Germany, whether in standard design or tailor-made, set us apart.

Sales & Project Management
Gerresheimer is one of the world’s leading partners of the pharmaceutical and healthcare industry. We have about 10,000 employees worldwide that manufacture where your customers and markets are. The product range includes pharmaceutical packaging as well as products for the easy and safe administration of medication.
The Gerresheimer company has been one of Letzner’s loyal customers for many years. Since 2001, several, site-specific PW, HPW and WFI generating systems including the corresponding distribution and storage systems have been delivered to the facility in Bünde. An automated ring line system supports Gerresheimer in the distribution of liquid brine and helps supply all softening facilities.
Since 2019, Letzner is also involved in the Regensburg site. Here, the usual Letzner quality was installed in the form of a PW generating system and a WFI generating system with WFI storage and distribution. Our cooperation involves turnkey projects qualified and documented to pharmaceutical standards for a structured and qualified project realization.
Allergopharma specializes in the subcutaneous immunotherapy (SCIT) and is a market leader in this field in Germany. The company offers a wide range of high-dose, hypoallergenic preparations, so-called allergoids, for SCIT. In addition, their portfolio includes a wide selection of allergens for diagnostics. Since becoming a full member of the Merck Group, Allergopharma have been leveraging the strong group network for research, development, internationality and other areas to further develop the immunotherapy for the benefit of patients.
When tendering the pure media facilities for the new production building, it was important for Allergopharma to get the required systems from a single source. These included a new pure steam generator, a new WFI generating and storage system as well as a new AP generating and storage system along with a uniform plant and control concept.
During the tendering and awarding phase, an integrated concept and the project team in charge of implementation were presented to the responsible technical support department for process systems, pure media supply, ventilation technology, building control systems and the organisation of maintenance and calibrations under the management of Mr Meinke. Allergopharma was ultimately convinced by the systems already installed by Letzner in other projects and their automation. The fact that in addition to construction and automation, commissioning and qualification also came from a single source was a further reason for the cooperation. The systems could thus be delivered on time and put into operation.
The Industrial and Provident Society of German Veterinarians (Wirtschaftsgenossenschaft Deutscher Tierärzte - WDT) is one of the leading organisations in the German veterinary pharmaceutical market and present in over 95% of veterinary practices. With a proud 114 years of company history, the 280 WDT employees today produce products for the basic supply of veterinary
As early as 2002, Letzner was able to convince with PW and RD generation and their distribution systems at the Garbsen site. Today, more than 7,100 owners in their field profit from the high quality of WDT’s own preparations.
Because of its growth, the WDT decided to rely on Letzner’s renowned quality. The adapted PW generation with storage and distribution system and the combined system for the simultaneous generation of pure steam and WFI with the corresponding storage and distribution were installed in a process optimized way - despite the small footprint.
