Engine pre-heaters ensure that vehicles and machinery can be used immediately after starting and operate at their best. Furthermore, to keep (large) battery packages at a stable temperature which increases lifetime. Our pre-heating systems play a role in improving energy efficiency of processes and contribute to goals of the zeroemission market. Whether it is heat recovery, reduction of emission and application in renewable energy systems. Our pre-heating systems can be implemented into various zero-emission applications such as hydrogen generators, solar thermal systems and battery storage systems.
