Custom design Expansion tanks

We offer the possibility of a fully customized expansion tank. Consider a special design of the expansion tank or different dimensions. Expansion tanks are standard supplied in steel. Stainless steel and aluminum expansion tanks are available on request.

Expansion tanks are an essential component of any vessel with a marine engine, including electric ones. They help regulate the pressure and temperature of the engine coolant by providing additional space for the coolant to expand as it heats up. Without an expansion tank, excess pressure could build up within the cooling system, leading to leaks, engine damage, and potentially dangerous situations.

At Blokland, we are specialized in designing and manufacturing high-quality expansion tanks that are suitable for any type of vessel with a marine engine. Whether you have a small pleasure craft or a large commercial vessel, our expansion tanks are the perfect solution for your cooling system needs.
