Decentral drive technology requires special solutions. The inverters must be adapted to the prevailing environmental conditions and must reliably fulfil their tasks. KOCH offers fitting brake resistors with a high protection class. KOCH is also capable of meeting specific requirements at any time. The solution shown here has a wave hose, which was needed as insect protection for an airport project. KOCH offers many other customer-specific solutions. 

A​dvantages:

• compact
• protection class up to IP 65*
• highly impulse secure
• low inductance
• "intrinsically safe"** under persistent overloads

*Test conditions: Water jet from nozzle with an inner diameter of 6.3mm, volume flow 12.5l/min +/- 5%, water pressure in accordance with the volume flow, distance 2.5-3m, test duration 3min

**the intrinsically safety is usually given with 4 time of permanent type power
