RK-13

RК-13 Repair kit for locomotive air conditioner

The advantages of using the repair kit RК-13-Х-Y1:

1. Use of semi hermetic compressor reduces the likelihood of refrigerant leakage.

2. The use of static inverter:

  • Virtually eliminates the need for maintenance.
  • Excludes significant starting currents.
  • Reduces power values.
  • Facilitates the operation modes and increases the service life of car batteries.
  • Ensures a smooth transition between the cooling stages.
  • The engine compressor on three-phase voltage 80 V can be applied to the inverter circuit with a single energy conversion.
  • Cooling the drive by refrigerant increases reliability in high temperatures.

3. Improved reliability through the use of proprietary solutions.

4. Full installation compatability with mechanical, electrical and hydraulic connections of existing equipment.

5. Can be installed in the depot.

6. Improves the comfort of passenger cars by reducing noise and vibration.

7. Reducing the mass of the car and the load on the undercar frame.

It is installed into the compressor frame instead of the compressor unit equipment MAB-II. At the same time the frame is not exposed by any mechanical refinements.
