Hotstart CXM Coolant Heating System

The HOTSTART CXM is a compact, high-performance coolant preheater designed for marine propulsion engines, as well as diesel and gas engines in stationary land power and mining applications. It enables engines to start clean and reach full power instantly, eliminating warm-up delays and idling.

Available in voltages up to 690 V with 50/60 Hz compatibility and custom interfaces, the CXM integrates easily into existing ship power and control systems. Built for reliability and safety, it features a remote automatic function, customer interface connections, pressure relief valve, and dual PT-100 sensors for precise temperature control.

Ideal for humid marine environments, the CXM prevents condensation in cylinders during cool down, reducing maintenance and improving engine readiness. Backed by HOTSTART’s global network, it offers fast delivery and localized support worldwide.
