Kohler exhibited the K-HEM 2504, a hybrid unit generating a combination of electrical and mechanical power consisting of a KDI 2504TCR 55.4 kW diesel engine that complies with Stage V legislation without SCR, and a 48 V electric motor that guarantees 19.5 kW peak power and 9 kW continued power, and maximum safety levels due to the voltage. The new K-HEM 2504 hybrid unit offers even more efficient DPF management making the regeneration processes fully transparent for the end user, as it is possible to exploit the temperatures reached to recharge the battery pack, according to the company.

The modern and advanced DNA of the Kohler KDI 2504TCR engine makes it the perfect partner for an electrical unit: KDI engines deliver a very high performance and the combination with electrical power can equal, if not exceed, the performance offered by higher spec engines in terms of horsepower, as well as a smaller footprint.

K-HEMs allow excavators to have faster and more precise movements compared to the past, with improved efficiency and productivity. Kohler hybrid units guarantee the general optimisation of machines and the possibility to store surplus energy in the batteries to be delivered when needed, drastically reducing running costs; the applications will enjoy the inherent flexibility of parallel hybrid systems, namely the possibility to run on mechanical energy, on mechanical energy plus electrical energy, or with electrical energy alone, soon available for the K-HEM range.
