A range of coolant expansion tanks from Mann+Hummel, suitable for mobile and stationary industrial applications, is available with volumes from 1.5 to 8 L (0.4 to 2.1 gal). The series consisting of 24 coolant expansion tanks has a modular design, which allows integration of the tanks in almost any installation space. The coolant expansion tanks are designed for heavy-duty applications and are temperature resistant, pressure resistant, and resistant in relation to the chemical composition of the liquid. The available volumes cover engines with an output range up to 280 kW (375 hp). The transparent plastic of the coolant expansion tank enables visual inspection of the coolant level in the tank. The materials used are characterized by dimensional stability and prevention against corrosion and leakage, also under difficult operating conditions. The coolant expansion tanks are cost-effective for small- to medium-sized quantities.
