Frequency inverter water-cooled with improved robustness and efficiency
Altivar 61Q is a variable speed drive with water cooling from 110 to 800 kW. It is used in harsh environments, when drives with particular robustness are required. The integrated liquid cooling permits optimal dissipation of the lost heat from the power part and therefore optimizes the encapsulation of the whole electrical drive unit.
Highest robustness during operation
Reliable and simple installation
Consistency to the Altivar products
Liquid cooling of electrical and mechanical units is already best-proven in the area of plastics machines. Due to their robust cooling system, the Altivar 61Q drives can be particularly integrated into existing cooling concepts. The Altivar 61Q shows flexibility for different cooling concepts:
The lost heat of several drives with high power in an electrical room can easily lead to overheating of the operating room. On the other hand, when the main losses of the drives are dissipated to a liquid coolant, the installation of an expensive air conditioning can be avoided. With their internal liquid cooling the Altivar 61Q are optimally prepared for these applications. In this concept about 85 % of the inverter losses are dissipated from the electrical room by means of the cooling water. The Altivar 61Q shows flexibility for different cooling concepts:
