Customized Dosing Systems

In the field of dosing and pump technology, the requirements and dosing processes of our customers are very different. Individual challenges must be recognized and solved.

As a system provider for dosing technology, sera is able to understand these different processes and to develop tailor-made solutions for every customer requirement.

Municipal Utilities Winterberg

Winterberg, a centre of tourism in the Sauerland region with 13,000 residents across 15 districts, has experienced a development boom in recent years and – from the point of view of tourism – has all the features of a typical destination in the central German uplands.

In order to give winter sports enthusiasts 80 days of guaranteed snow a year, a plan was drawn up in the 1990s to make snow. The scheme worked: in 2012, Winterberg recorded more than 1 million overnight stays for the first time - and that was in commercial hotels alone. Unrecorded stays with small and private accommodation providers and about 1.5 million day visitors a year should be added to this.

Phnom Penh - Heineken Brewery

Approximately 50 million tons of caustic soda are produced annually and used in various ways in industry. sera offers a cost-effective system solution specifically for use in the food industry, which has a variable but large demand for alkaline cleaning agents such as caustic soda. This enables the secure and efficient preparation of caustic soda based on sodium hydroxide (NaOH) in solid form (pellets, flakes, pearls or powder) and water. 

Bonn - Waste incineration

Recycling of the waste from Bonn and the surrounding region is carried out by Müllverwertungsanlage Bonn GmbH (MVA), a subsidiary of Stadtwerke Bonn (Bonn Public Utilities). Over 1,000 tonnes of waste, which has to be disposed of in a safe and environmentally friendly way, is delivered to it every working day. In a complex thermal process, the waste is first incinerated and then processed. Flue gases are created when the refuse is burnt.

STAINLESS STEEL DOSING SYSTEMS

When mixing caustic soda from solids, an exothermic reaction with temperatures of up to 95 °C occurs. The sera CausticPrep is designed so that the user can easily feed the caustic soda flakes into the process from a safe distance.

Sample application

Preparation of caustic soda from pellets and flakes.

Design

The stainless steel hopper is filled with solids by means of a screw conveyor; these solids are fed into a feed hopper by the operator. The safety of the user is ensured by the distance to the hot tank.
