Heat recovery systems - Import export

Heat recovery with the help of heat exchangers In industry, waste heat occurs at many points in the production process, which is often released into the environment without being used. In many cases, energy is even used to cool the waste heat flows from production so that they can be released into the environment. Heat exchangers (also called heat exchangers) are used for heat recovery so that the waste heat generated in the production process can be used again in the company. Gaseous or liquid media Waste heat can be in the form of gaseous media (e.g. warm exhaust air, steam, exhaust gases, etc.) or in the form of liquid media (e.g. hot water or other liquids). With the help of heat exchangers, the waste heat can be recovered from both gaseous and liquid media and then made available to the production process at a suitable point as energy in gaseous or liquid media. This process is known as energy recovery or also as heat recovery.

With heat recovery systems in industrial environments, the heat contained in the exhaust air is efficiently used to heat air or water. A very efficient use of this energy is the preheating of dryer supply air. The heat can be used continuously here. This warm exhaust air is also suitable for heating buildings. Depending on the local conditions, both airtoair heat exchangers and airtowater heat exchangers can be used for this purpose. The heated air, in turn, is fed into production and factory halls or other areas of the building. This type of supply air heating is particularly costefficient. Such recovery systems also have a positive effect in terms of environmental compatibility. Waste heat from industry that is harmful to the climate is no longer released into the environment but remains in the cycle of the production process or building heating. The systems are also suitable for cooling rooms when outside temperatures are hot, for example.

Cooling tube for fast and flexible cooling. Made out of high quality V4A stainless steel spiral tubing for efficient heat transfer. Unlike conventional corrugated pipes, the smoother shape of the (spirally-shaped) surface improves heat transfer and cleaning.

Our heatrecovery systems heat fresh air with the thermal energy of exhaust air and can be placed directly on top of a stenter frame. This system can also be retrofitted for older dryers. The benefits are high energy savings which allow payback periods of less than two years, depending on the layout and process, highly efficient platetype heat exchangers with nonstick coating, optimum ease of maintenance by removable drawersized heat exchanger modules, external cleaning of the heatexchangers in a hot water bath with ultrasonic cleaning equipment, high power density, higher than with usual tubetype heatexchangers.

A complete centralised cooling plant, including the required peripherals, can be set up in the absolute shortest possible time at the subsequent place of installation and is immediately ready for use by means of prefabrication and installation in a container. This way, the otherwise high investments for an operating building, the costs for installation and start-up of the plant are reduced. Container cooling plants almost have no limitations in terms of their capacity and variety of possible combinations. They are supplemented by peripheral systems such as water treatment and water preparation systems or compressed air compressors. A series of different cooling systems and the combined systems composed of these units are primarily available: Chiller Heat pump systems for heat recovery Cooling tower combined with a KU system as a closed, clean cooling circuit Air heaters for direct recovery of heat hermeticool-units hermeticool hybrid-units

The correct air budget is an often underestimated quality factor in surface treatment technology. Where heating, cooling, movement and filtration is concerned, a great deal of energy can be saved with innovative solutions. Supply air systems replace extracted air quantities and ensure: Supply and exhaust air systems Supply air systems ensure draught-free and clean ventilation of work rooms, while high-efficiency exhaust air systems with fans and filter systems are responsible for the necessary air exhaust. This takes place with the lowest possible use of energy and with the longest possible intervals between maintenance and cleaning operations. We also offer intelligent air solutions for dryers, pre-treatment plants and cooling zones. Heat recovery A further important point is heat recovery. We can achieve up to a maximum of 80% heat recovery with the most diverse systems. Cross-current, rotary heat exchanger, heating pipe or circulatory systems – they all have their own advantages and efficiencies, which we integrate according to requirements during the planning of the plant.

Exhaust air purification and heat recovery systems are generally not standard applications, even if individual assemblies are now modular. We have made it our goal to offer our customers the best solution for their task. To do this, we take a step back with our customers in order to gain an overview of the whole. Together we look at how the exhaust air is generated and try to start our concepts right at the point of origin. Only then can we decide which exhaust air system is the most economical when considering the total cost of ownership and compliance with the limit values. Should an extended consideration be necessary, we can accompany you from basic to authority to detail engineering. In addition, it is not uncommon for pilot tests to be offered, which lead to the later real scale of the systems by means of scaleup. With these consulting and engineering services, we offer you a manufacturerindependent package with which you can make the right decision for your company.

The thermal incinerator (TI for short) is a system which converts gas or vaporous pollutants found in exhaust gas into non-polluting compounds by way of direct combustion. This machine is characterized by: The thermal incinerator (TI for short) is a proven and robust plant for the conversion of organic pollutants (VOCs, etc.). Today it is used especially for processes which involve high exposure to condensation or dust, or for specialized solutions requiring greater heat recovery potential. An example of this would be exhaust gases containing plasticizers or siloxane. The modular design of the combustion chamber and heat exchanger especially is conducive to servicing and cleaning compared to other designs. The polluted air is forced by means of a centrifugal fan into the tube bundle heat exchanger where it circulates around the tube bundle in a cross-current fashion. The heat exchanger can be designed for an efficiency of up to 70%. The pollutants are converted in the combustion chamber at a temperature of around 760 °C. After extensive heat transfer to the raw noxious gas, the cooled clean gas leaves the plant, where it can be supplied to various heat recovery systems (or a combination of several). The auxiliary burners can be operated with natural gas or propane or light heating oil.

nduction Heating and Joining in one turnkey system. This turnkey system is used to heat electric motor housings with various dimensions for a wide range of joining processes. Example Heating System 1: the die-cast aluminium housing for an asynchronous motor (diameter 450 mm) is heated to approx. 290°C in approx. 5 minutes to fit the wound stator package. The parts are loaded and unloaded from the feeding belt parallel to the working time. The heating process takes place in two independent work stations. The generator has a switched output which means that only one generator is required for the two heating stations. The system is controlled using a SIEMENS PLC controller. Example Heating System 2: the aluminium housing (diameter 140 mm) of a synchronous motor is heated to approx. 280°C in approx. 3 minutes to fit the stator. The component is loaded into and unloaded from the heating station semiautomatically. The system is controlled using a PLC.

The operating mode can be flexibly adapted to the conditions on site. Thus, the devices can be used in all areas. Hot air hose systems can also be connected without any problems thanks to the high-performance radial fans. Consequently, effective heating from outside is also possible without any problems. The recirculation module ensures efficient and economical operation. The oil burner blowers are made of high-quality materials by renowned manufacturers. They work so efficiently that 93% of the energy can be converted into heat.
