Why the right investment strategy makes all the difference
A reliable power-to-heat concept converts electrical energy – whether from the public grid or from the company’s own renewable sources – directly into precisely controlled process heat. However, the key added value for the business lies not solely in the heat generator. It is the combination of intelligent control, precise regulation and well-thought-out planning that makes electrification an economical and worry-free solution.
For the transition to run smoothly in day-to-day operations, four key factors are crucial:
-
Compatible with the existing infrastructure
Whether for low power or in the megawatt range: the system must be compatible with the plant’s electrical system. For small to medium-sized requirements, the tried-and-tested 400 V network is used. For large industrial plants in the megawatt range, the use of 690 V is often advantageous: it reduces cabling costs, space requirements and unit costs.
-
Protection against breakdowns and a long service life
To prevent the components used from wearing out prematurely, the system is controlled by intelligent electronics. The heating elements are switched on and off in turn, ensuring that all parts are subjected to an even load. In addition, the current of each individual heating element is continuously monitored. This detects irregularities at an early stage, protects against unplanned production stoppages and ensures maximum availability.
-
Actively reducing electricity costs
A modern system dynamically adjusts its heating output. If the heat demand in the process changes or the market price of electricity fluctuates, the control system reacts automatically. This allows you to make targeted use of periods of low electricity prices on the market or surplus energy from your own photovoltaic system to significantly reduce operating costs.
-
Rapid implementation without long waiting times
As the heat is generated electrically – and is therefore completely emission-free – directly at the process, there is no need for chimneys, fuel storage or time-consuming emissions-related approval procedures. Pre-assembled complete systems on a base frame (“Plug & Heat”) also reduce on-site installation work to a minimum.
