Our marine heat exchangers include direct cooling, heat exchanger cooling, and keel cooling process. Our keel cooling process is suitable for small boats operating in shallow weedy water, but the need for pipe work external to the hull is a severe limitation.

Our hydraulic oil coolers are suitable for heat transfer fluids, lubricating, transformer, and quenching oils. They easily remove unwanted dust.
