The wastewater in the sewers is an ideal source of energy when combined with heat pumps and cooling machines, for heating and cooling of buildings. Per our experience, the minimal requirements for such a plant include: a wastewater flow of approx.. 10 l/s a wastewater temperature level of about 10°C a power requirement from 100kW (for heating and cooling from ca. 50kW). During the course of conveying wastewater to the sewage treatment plant, there are many possibilities for exploiting thermal energy. Wastewater can also be used many times over consecutively as energy source. Despite new inflows, or the confluence into larger canals, but also through heat influx from cooling systems, the change in temperature of the wastewater is mostly marginal. Innovative cities have ready energy guidelines (energy plans), based on which you can orient yourself to find out whether there is a suitable wastewater canal in your near vicinity (maximally approx. at a distance of 200 m).

The use of energy potential at the place of its origin is optimal. Ensuring the heat transfer in the heat exchanger is thereby a vital criterion and requires customized solutions. The torrent of sewage flow in buildings is collected in a containment volume for generating energy using heat exchanger for heating and cooling. No retention volume is necessary for continuous outflows and process heating. This can be applied, for instance, in apartment buildings, residential buildings, communal buildings, hotels, thermal baths, swimming pools as well as in different energy-intensive industries, such as in foodstuffs, chemicals and pharmaceuticals.

SMARTCOLLECT is a data management software for easy and safe measured data acquisition as well as data analysis focussing on energy management. SMARTCOLLECT acquires, stores, visualises, evaluated as well as automatically reports all relevant consumption data of power, water, gas or heat. A modern graphic user interface permits intuitive and easy operation even in numerous measuring points. Functions and measuring points may be very easily supplemented at any time due to the modular design.

The steam and heat computer RMS621 calculates steam mass, steam heat quantity, net steam quantity, steam-heat differential, water heat quantity and water-heat differential in up to 3 simultaneous applications. Bi-directional and splitting range measurements are possible. It supports analog, PFM or pulse signals for flow and pressure sensors. Temperature sensors can be connected in 3- or 4-wire connection or via transmitter. A loop power supply is available for each analog or pulse input.

The measurement is done uninterrupted in all four quadrants and can be adapted optimally to the system to be monitored. Both the average time of the measurement and the expected maximum signal level can be configured. • System state monitoring: class 0.2 • All-purpose: V/I, P/Q/S, f, PF etc. • Remote communication via Modbus • DM5S: Energy metering: class 0.5S • DM5F: Response time 15…25ms • Assisted commissioning • Configuration with or without power supply

Due to the physical properties of almost all materials which can be treated by infrared, the medium-wave radiation in the range of 2,5 µm – 3,5 µm gets the best results. This is just the emission range where our KRELUS-IR-heaters gets the highest performance Our modular and custom made IR-heaters leave all opportunities for the individual, almost endless applications. The KRELUS-IR-heaters are working with the shortest reaction time ON/OFF. This guarantees the highest economical use of electrical energy and fastest adaption to required temperatures on product surfaces. Consequently our IR-heaters are highly active with gentle action for treated products and even more important: they are energy saving.
