Marine Main Engine Jacket Fresh Water Heater | VRCOOLER Custom Marine Preheating Heat Exchanger
VRCOOLER, a professional Chinese manufacturer and exporter of full-series marine heat exchange equipment, supplies reliable marine main engine jacket fresh water heaters for all low-speed and medium-speed propulsion engines including MAN B&W, Wärtsilä WinGD, Mitsubishi, Yanmar and Caterpillar. Widely installed on container ships, bulk carriers, oil tankers, chemical vessels, offshore platforms and tugboats, this equipment is an essential auxiliary unit for safe cold start of marine main engines.
Core Function of Jacket Fresh Water Heater
When vessels stay anchored, berthing or navigate cold sea areas for a long time, the temperature of jacket cooling fresh water drops sharply. Low-temperature cooling water will lead to incomplete combustion, severe thermal shock to cylinder liners, pistons and crankshaft, increased wear and difficult startup.
VRCOOLER jacket fresh water heater continuously maintains jacket water temperature at 40–60°C before engine startup and during standby:
1. Eliminate cold start thermal stress, extend main engine service life
2. Ensure smooth ignition and stable low-load operation
3. Reduce fuel consumption and black smoke emission during startup
4. Protect cylinder components from low-temperature corrosion
