Our range of products
Energy-optimized cooling system for feeding production machines as well as air-conditioning and ventilation systems. With heat recovery for using cost-free waste heat and a non-glycol winter relief for reducing the power consumption of chillers.
The demand for modular energy centers has considerably increased during the recent years.
The reasons for this development may surely be a quick availability, flexibility and the space-saving design of these powerful ONI systems. From the supply of cooling and cold water to heating power and compressed air including pumps, tanks and controllers, the entire technology is integrated into modular units in a compact manner. Hi-tech and quality products are combined in our modular energy centers.
Whenever we design a ventilation system for a company in the plastics processing, quality assurance in production is always the focus in planning and implementation. However, the operating costs of such systems are a crucial factor which needs special attention. This is the reason why ventilation or air-conditioning systems planned and implemented by us are always designed on the basis of „the lowest possible costs“ principle for the plant operator.
ONI-EtaControl technology is a further development of the energy optimization for injection molding machines developed by ONI more than 30 years ago.
With this technology, electricity savings on injection molding machines of up to 35% can be achieved. Because the costs for the power consumption of the machines have a large share of the total costs, the EtaControl technology finances itself in a very short time.
The key component of this technology is a controlled oil flow management system which automatically adjusts itself on demand to the energy requirements of the machine during the cycle process and to the respective molding.
The use of ONI-EtaControl technology is worthwhile. It is an active contribution to environmental protection that finances itself in a short time.
Our heat recovery systems use waste heat of 35 ° C from cooling water systems for heating purposes. Free waste heat resulting in valuable heating energy saves heating oil and natural gas and contributes to environmental relief.
The practical experience shows that our heat recovery systems finance themselves in the shortest time by the saved energy costs. Customers use the money saved through heat recovery to buy new production machines.
The use of heat recovery makes an active contribution to environmental protection.
