Precise process heat for chemicals & pharmaceuticals

Precisely controllable heating processes play a crucial role in the chemical and pharmaceutical industries. Constant and reproducible temperature control is central to syntheses and distillations as well as fermentations, drying processes and stability tests. In order to meet the high quality and safety requirements of these industries, specialized heating elements, Temperature probes and pressure measuring devices are used, which are adapted to difficult environments, aggressive media and strict regulatory requirements.

Heating elements in chemical and pharmaceutical applications must not only provide reliable heat, but also be resistant to solvents, acids and bases. Homogeneous heat distribution is also important to allow reactions to take place in a controlled manner. Typical solutions range from robust cartridge and tubular heating elements to flexible silicone heating mats to heating baths for laboratory use. Silicone heating mats are often used for the temperature control of tanks, pipes or IBC containers, where they deliver a high surface area output despite their low height.

Precise temperature detection is just as important. Temperature probes such as Pt100 or Pt1000 sensors offer high measurement accuracy and are suitable for both reactors and hygienic processes in the pharmaceutical industry. Hygienic connection types such as Tri-Clamp ensure that the sensors can be easily sterilized or integrated into CIP/SIP processes. Thermocouples that can reliably detect temperatures in the range between 800 and 1200°C are used for high-temperature processes, such as in ovens or drying systems. Modern variants are also designed in such a way that they provide stable measured values over the long term and also function reliably under pressure, vibration or chemical stress.

Pressure gauges complete the control concept and make a significant contribution to process safety. In chemical reactors, fermenters or filtration systems, continuous pressure monitoring is essential to ensure stable reaction conditions and to detect dangers such as overpressure at an early stage. Mechanical pressure gauges made of stainless steel are just as common here as electronic pressure transmitters, which transmit precise measured values directly to higher-level control and management systems.

The interplay of heating, measuring and control enables efficient and safe system management. Heating elements generate the required process heat, while Temperature probes and pressure sensors monitor all relevant parameters. The measured values obtained are processed in precise control systems that dynamically adjust the heating output and thus ensure stable production conditions. This results in reliable and reproducible processes that meet the high quality requirements of the chemical and pharmaceutical industries.

Pressure gauge

A pressure gauge is a measuring device for recording and displaying the physical pressure of a medium (e.g. liquid, gas, etc.). The relative pressure – i.e. in relation to atmospheric air pressure – is often measured. Pressure gauges filled with a liquid (e.g. glycerine, silicone) are particularly suitable for Universal probes for the measurement of vibrations and high dynamic pressure loads. The damping liquid prevents the formation of condensation and the penetration of corrosive gases into the housing. Typical areas of application are in the packaging machine industry, petrochemical and plant construction and, for example, in power plant construction.
