Energy saving technology

Process cooling accounts for a large part of your production’s total energy consumption.

Thus, your cooling system provides you with a highly effective setscrew when it comes to optimizing your production efficiency. You will benefit from that in multiple ways, not only regarding your operational costs. For each kilowatt hour of electrical energy, an average of 489 g of are emitted. Legal requirements are continuously tightened, new regulations are strong incentives for producing companies to decrease their energy consumption and the associated CO2 emissions.

 For companies establishing an energy management certificate according to DIN ISO 50001, saving potentials in the cooling area are an important aspect. Therefore, Reisner cooling systems are absolutely optimized in terms of energy efficiency. We take different measures and combine only highest-quality components in our systems. Our success is easily masurable – the savings speak for themselves.

 These Reisner Cooling technologies increase your production lines’ energy efficiency:


Variable Condensation

Variable condensation is a successful Reisner in-house development that has been proving itself for yeara now. This technology adjusts the chiller’s condensation temperature variably to the exact ambient technologies that are common in Europe. Compared to a system with a conventional control unit, the Reisner Vario system only consumes a small percentage of electrical energy - this drastically lowers the operational costs.


Winter relief/free cooling

When outside temperatures fall below certain levels, many processes need less cooling capacity. Reisner cooling systems equipped with winter relief technology use dry coolers that gradually relieve the chiller of its load until they finally take over completely. The Reisner control unit continuously adjusts the balance so that the system's efficiency is maximized at all times.

Waste heat recovery

Cooling units withdraw heat from goods and media that require to be chilled - for example from plastics during the production process. Reisner systems can regain this heat and return it to support the heating of production halls, office buildings or processes. This reduces the consumption of primary energy and accordingly the company's consumption costs.


Speed control in compressors

The newest generation of Reisner chillers is frequently equipped with speed-controlled compressors. They provide a continuous regulation which is extremely effective, especially when the system is operated in the partial-load range. Always adapted to the perfect operating point, the speed-controlled screw compressor contents itself with a very low energy input compared to conventional options.

Speed control in pumps and fans EC fans

Even beyond the core field of cooling technology, Reisner concepts unlock interesting energy saving potentials, for example by including condensers with electronically commuted (EC) fans. They are powered by direct current motors that can be controlled at a high level of precision. Providing the same capacity as conventional condenser fans, they consume up to 70% less energy. Aside from that, they are clearly superior concerning their noise emissions.

Speed-controlled pumps always adapt to the current operation points. Especially under partial load, Reisner systems with speed-controlled pumps always dose capacity and consumption perfectly. This way, they provide an efficiency optimization that cannot be realized by regular pumps, with the effect of drastic cost savings compared to an operation without speed control.
