Permanently Safe Operation of Gas Engines

With increasing engine power and higher levels of efficiency, the thermal loading of engine components adjoining the combustion chamber increases. The main task of the coolant is to discharge the combustion heat from these components (component cooling) and provide it to the customer as useful heat. The coolant is therefore not only responsible for a continuously safe engine operation, but also for efficient use of the plant.

MWM – Many Years of Experience with Gas Engines

Like lube oils, coolants are tested in intensive field tests and approved for use. Based on the long-standing experience of our development engineers, as well as extensive assessment of field experiences of the MWM service organization, the inhibitor technologies for MWM Premium Antifreeze –20 and MWM Antifreeze Advanced have been selected together with a strategic partner.

High Profitability

The focus when selecting the MWM Premium Antifreeze –20 inhibitor technology was on a low formation of deposits on thermally high-loaded components, since the heat transfer is inhibited by the formation of isolating layers in these areas (primarily cylinder liner and cylinder head), which may have adverse effects on oil consumption and valve wear. MWM Premium Antifreeze –20 is characterized by excellent heat transfer, safe frost and corrosion protection and simple handling. The availability and economic efficiency of the plant is increased due to the use of MWM Premium Antifreeze –20.

The inhibitor technology for MWM Antifreeze Advanced was selected to minimize the deposit on components subject to high thermal stress and to maximize the lifetime of the coolant. The high-performance coolant is free of silicate, phosphate, amine, nitrite, and boron and is suitable for all MWM gas engine series. In this MWM coolant, only organic inhibitors are used for corrosion protection. These do not leave any hard deposits on the engine components, which could impair the heat transfer. The corrosion protection inhibitors are not consumed during operation and thus enable a long useful life of the coolant. As MWM Antifreeze Advanced is a ready-to-use mixture, the coolant always has the right inhibitor and glycol concentration. This prevents incorrect dosing.

Optimum Coolant Composition: Protection Against Corrosion and Consumption

The heat conductivity of coolants drops with an increasing glycol content. With a glycol content of 35 Vol. %, MWM Premium Antifreeze –20 and MWM Antifreeze Advanced are the optimum products for safe frost protection up to –23 °C and have very good heat transmission properties at the same time.

Non-organic and organic inhibitors are used in MWM Premium Antifreeze –20 as means of corrosion protection. These form a thin, heat-permeable protective layer on the wetted components.

With MWM Antifreeze Advanced, only organic inhibitors are used as corrosion protection. These do not form any hard deposits on wetted components, which could impair the heat transport.

In order to ensure reliable protection of the engine, the correct inhibitor concentration of the coolant is particularly important. Overconcentration poses the risk of damage to wetted components, and too low concentration of the inhibitor cannot guarantee a sufficient corrosion and cavitation protection. If cooler frost protection concentrates are used for preparing the coolant on site, the correct composition of the mixing water must also be considered, otherwise there may be deposits in the area of the exhaust heat exchanger.

As a read-mix, MWM Premium Antifreeze –20 and MWM Antifreeze Advanced always have the correct inhibitor and glycol concentration – an incorrect dosage is thus prevented. MWM Premium Antifreeze –20 and MWM Antifreeze Advenced are suitable for all plant configurations and can be comfortably filled during maintenance.
