Parallel Hybrid Transmission

Parallel Hybrid Transmission PHT

The Parallel Hybrid Transmissions, designed for heavy duty applications with diesel engines from 200 HP to 1300 HP, has a built‐in 24VDC electro‐magnetic clutch working independently from any other part of transmission to engage and disengage the diesel engine from the driveline. The PHT has an input housing SAE 0‐1‐2‐3 and SAE 11.5”, 14” or 18” elastic coupling for direct connection to the engine housing and flywheel. 

Very strong PTO/PTI: 1500 Nm to transmit. Unit is executed with a ratio from/to PTO/PTI of 1,47 or 1,7.

This feature is giving following advantages:  

‐     We can optimize the speed for generator/electric motor to get optimum efficiency 

‐     By increasing speed to PTO, size of electric parts decreases

‐     By reducing speed from PTI, torque of motor increases

-    Unit can be installed vertically or horizontally (using optional pump)

‐     Output housing SAE 1 and 14” connection to mount directly marine gear or output flange


  • Oil pump kit for forced lubrication and/or cooling

  • Speeds sensor at PTO/PTI

  • Electric oil level sensor

  • Silicon temperature sensor


    Advantages of our PHT system:

  • Due to a very strong PTO/PTI a large electrical generator/motor can be mounted.

  • Due to the ratio a smaller electrical package can be installed at higher rpm.

  • Longer service life time of diesel engine.

  • Dual electrical use as generator and as motor.

  • By reducing speed from the PTI, the torque of the motor increases.

  • Unit can be installed vertically or horizontally (with additional oil pump kit).

  • Ships which require full engine power for a short time can install a smaller diesel engine by adding electric power when needed.

  • Generated electricity can be stored in batteries or used for on board systems.

  • Bureau Veritas approval is available.
