The off-grid solution with the new energy storage system – higher efficiency, reduced noise emissions and optimised generator utilisation for applications on construction sites, bridge renovations or tunnel constructions are just some of the results achieved with the energy storage system.
Its underlying principle is simple but efficient: While the generator is running, it supplies the connected consumers with electricity and simultaneously charges the batteries installed in the energy storage system. The energy storage system absorbs load peaks and allows generators to operate in the optimal power range. As a result, the connected diesel generator can be smaller and therefore more cost-efficient. As soon as the load decreases, the power generator is automatically stopped, and the energy storage system silently supplies the consumers from its batteries. Consumers with a lower power draw are supplied exclusively via the energy storage system. For applications involving consumers with a high-power draw, such as a crane system, the energy storage system automatically starts the generator and automatically synchronizes the grid. Both devices now work in combination, whereby the power of both is added together.
When every second counts – ENDRESS DIN power generators, power supply systems with IT/TN mode switching and mobile floodlight systems are the safe and robust power source for fire brigades, disaster control and emergency services. Due to increasingly modern consumers, the demands on mobile units are also rising. In the development process at ENDRESS, customer and market needs take center stage. Therefore, we constantly update our product lines to meet the requirements of today and tomorrow.

The ENDRESS motor pumps perform reliably and economically anywhere where no electricity is available and feature a high delivery rate, high-quality seals and an automatic low oil cut-off system. All ENDRESS motor pumps are self-suction pumps based on the centrifugal pump principle and are driven by durable and powerful YAMAHA motors.

Maximum performance in a miniature design: The reliable and powerful temperature switches from Microtherm are perfect for installations in tight spaces. They ensure optimum overheating protection even under extreme conditions and in the smallest of spaces.
Applications:
- Home: For e.g. roller shutter motor, aquarium, toaster, kettle, extractor fan, washing machine, dishwasher, air conditioning units, coffee machine, fans and ventilators.
- Industry: For e.g. pump and fan motors, electric motors and heaters, transformers, cooling units; power tools
- Automotive as overheating protection for motors: Windscreen wipers, heated side mirrors, seat heaters, motor windings
- Charging park: Temperature management in cooper or aluminium windings and protection of electric motors by initiating protective functions, temperature monitoring in battery management to prevent batteries from overheating, temperature monitoring of high-current connectors
- Hospital: Incubators, hospital bed motors, ventilation systems, ventilators

Microtherm sensors are used for temperature measurement. The value measured by the sensor is used for overtemperature protection, to trigger functions or to display the measured temperature. Our temperature sensors not only safeguard and protect electric motors and/or electric heaters by switching them off, but also provide signals for temperature indication, power reduction or other functions. With the help of our diverse manufacturing processes, we embed sensor elements in customised assemblies. This allows us to add value to a pure sensor element and build cost-effective measurement systems.
Applications:
- Home: Power tool, vacuum cleaner and many more
- Industry: Pump and fan motors, electric motors and heaters, transformers, cooling units; power tools and many more
- Automotive as overheating protection for motors: Windscreen wipers, heated side mirrors, seat heaters, motor windings
- Charging park: Temperature management in cooper or aluminium windings and protection of electric motors by initiating protective functions, temperature monitoring in battery management to prevent batteries from overheating, temperature monitoring of high-current connectors

The Microtherm temperature fuses of the respective series automatically open the circuit of the connected device if the rated switching temperature is exceeded and must be replaced after being triggered.
Applications:
- Home: For e. g. refrigerator, hair dryer, smoke detector (installed as a fire alarm unit in ventilation ducts of buildings)
- Industry: Pump and fan motors, electric motors and heaters, transformers, cooling units; power tools and many more
- Hospital: Incubators, hospital bed motors, ventilation systems, ventilators

We offer our customers a very high degree of flexibility in the rapidly developing market for electrified highway and last mile vehicles thanks to our application-specific HV boxes. We serve quantities of 5 to 40,000 units per year. Due to the extensive production network of PRETTL with over 40 locations worldwide and dedicated plants, we are also able to produce smaller quantities locally close to the customer and thus realise the most ideal supply chain possible. This has a particularly positive effect on the CO² balance in the production of heavy components.

Our assemblies are developed according to customer requirements, primarily for use in electric vehicles. Depending on the application, these are designed conventionally via a PWM interface or with integrated control via a LIN or CAN interface, for instance. Taking into account the production costs, we integrate sensors and microswitches for position detection as required.

PMA offers solutions especially for handling demanding media. You will find our valve assemblies in applications for conveying fuels, urea and all types of chemical or biological mixtures in agricultural engineering, among others. Our expertise in mechanical design is complemented by PMA's own development department for hardware and software. Our valve assemblies are supplemented by sensors for monitoring position, flow, temperature and pressure conditions as well as integrated valve control and digital interfaces in the vehicle or system environment, depending on customer requirements.
