* Difference between PTB and PDY types: PDY type can mount a flywheel adaptor.
* Constant torque range: Based on the customer request.
* Inertia: Based on the customer request.
* Cooling water flow: Theoretical water flow when inlet water temp. is 25°C and outlet water temp. is 60°C.
* Specification is subject to change due to product modification.
