The system enlynx-EPC supplied by electrical technology specialist Riempp in Oberboihingen saves between seven and eleven percent energy and a similar amount of CO2 per year without any loss of comfort. This saving breaks down into between four and five percent in lower electricity costs and between five and six percent saving in electrical energy thanks to active energy management. The software-based solution containing 15 years of development combines energy-efficiency systems technology with energy and load management. The system acts as a digital node and communicates with more than 250 interfaces each of which represents an arbitrary piece of installed equipment at the customer’s site that requires or supplies energy.

Competitive Advantage
Friedrich Riempp, the man behind the solution says that “we have developed the product enlynx-EPC because, alongside saving electrical energy costs, it also communicates with the customer’s technical equipment via the active energy management emsyst 4.0”. The solution was developed by Riempp from both threads of energy management in buildings and plant together with machine maintenance and service areas. It stands apart from the competition thanks to its technical USPs.
As well as saving electrical energy costs, the smart control technology is able to adjust the voltage during live operation and smooth out grid-based voltage fluctuations. “The use of the EPC system means that electrical consumers are protected which extends their working life,” Riempp added a further benefit. The holistic approach to the solutions can be seen in the intelligent Smart Grid that measures consumption and demand via sensors and passes the information on to supervisory levels.
In parallel, the system can cap load peaks, prioritise regenerative power sources, or shift consumption to periods with lower electricity prices. The intellectual father of the invention summed it up, “the growing share of regenerative energies available in the total mix means that demand for our solution is increasing because we can be both flexible and constant with the electrical consumers”

Additional components such as battery storage and further air compressors can be added to as many points as possible to act as buffers that simultaneously allow the overall system to breathe. Their programming renders all processes to be controllable and alignable while also being coordinated and governed by external boundary conditions such as weather situation or energy demand.

DIN 50 001
enlynx-EPC also contains load management capability that enables entirely or short-term irrelevant consumers to be disconnected from the grid; stored energy to feed in during peak load; the base load to be reduced, and shifts non-scheduled production and storage processes to times when electricity is either particularly cheap or otherwise in excess so that energy sources using sun or wind do not have to be shut down.
For example, systems can be controlled via cell phones either with the calendar or timers, e.g. the drinks refrigerator in the canteen during company holidays, or the demand-oriented heating and cooling of meeting rooms, or the general quiet mode over the weekend. Riempp said “the program can even consider the quiet mode for business trips, personal holidays, or variable bank holidays.” The Riempp solution complies with the requirements for DIN 50 001; measured values are acquired, catalogued, and evaluated.

Existing buildings can be upgraded by connecting them via wireless sensors allowing the digital climate protector to be universally used in offices, industrial halls, schools, swimming facilities, clinics, computing centres, and shopping centres. Sensors and meters can read independently of the supplier and the measured values processed. There is more: enlynx-EPC can be combined with third party systems and the unified operating interface makes it easier for the operator and building technician to use in a nod to the Apple principle.

Historical Data & AI
The database acts as a source for recording and evaluation that enables proactive action based on seasonal values from earlier years by making use of experiential knowledge that borders on artificial intelligence. A uniform visualisation of building technology, e.g. HVAC, EMA, BMA, or video including trends curves and linked to the electrical schematics provided timely information about maintenance or investment needs. enlynx-EPC is available in three power classes: 150 to 300 KVA, 300 to 800 KVA and 800 to 2500 KVA, where EPC stands for electrical power compensation. The amortisation of the investment depends on the initial situation and complexity but lies between two and five years. This also depends on grants and the development of energy prices and CO2 tax. Our experience shows that users in the (foodstuff) industry have so far been able to reduce their CO2 emissions and consumption by between six and 10 percent.
Higher Climate Goal for Germany by 2030
Riempp sees a favourable market for his innovation considering the EU directive whereby member states must be greenhouse gas neutral by 2045, and Germany has the goal of reducing its emissions compared to 1990 by 65 percent, which is equivalent to 438 million tons of CO2.

The company based in Württemberg performed a quantum leap in 2023 in the field of power electronics with their three locations in the region of Stuttgart where they took over the electrical building equipment and machine maintenance and programming for almost 800 companies: A cooperation with technical universities led them to owner-led partners who provided an important part of the hardware in a single component for which Riempp had previously required 20 sub-suppliers.
The first system goes online this July at the packing company Fuji Seal located in Aichtal. The company was established in 1897 in Japan and considers it a duty to support environment protection and aligns its business activities with it (www.fujiseal.eu). Further notable systems at meat processors follow. Riempp said “the different local specifics mean that we are learning with every customer and can adapt our system to each customer individually for their different demands. Thanks to the energy management system emsyst 4.0, the solution is subsidised by the BAFA by between 25 and 45 percent, depending on the company’s size.
