The Black Max is the newest member of the Engine Saver family. It functions similar to our other device, in that it produces a continuous supply of dry, low humidity air that is injected into the engine crankcase through the breather tube. With the crankcase filled with air having a dew point temperature that is lower than the temperature of the metal engine parts, water will never form in the engine, and rust will not develop.
The biggest difference between the Black Max and the other Engine Saver device is the way in which the dew point of the air is lowered. Previous units utilized a chemical drying agent, with a colored indicator bead, to adsorb the moisture from the air passing through it. When the indicating beads changed color to pink, the material was no longer able to adsorb moisture. It was then necessary to recharge the drying agent by heating the material in an oven until the colored indicator returned to the original blue color. The Black Max uses an electronic cooling device to cool the air passing through it, condense the water, and lower the humidity of the air in much the same way that an air conditioner works. A low pressure pump pushes a flow of air through a condensing unit that is cooled by a thermoelectric device. As the air passing through the condensing unit is cooled below its dew point temperature, water condenses and the dew point of the air is lowered. The condensed water is collected within the Black Max, and evaporated so that no moisture is deposited outside the unit. The lower humidity air is then inserted into the engine crankcase through the engine breather as in our other devices.
The Black Max is capable of cooling the air passing through it to temperatures below freezing. As the water condenses from the air, ice will form in the condenser passages. To prevent the ice from eventually blocking the air passages, it must be melted and drained. A microprocessor is used to control the units operation. On power up, the thermoelectric unit is turned on, and the unit enters a cool down mode. Once the condenser has cooled down, (about 4 min's ) the pump is turned on and air flows through the condenser where it is cooled and its dew point is lowered. The dry air then passes through the engine breather tube and into the engine crankcase. After about 18 min's of operation, the cooling unit and the pump are turned off and the system enters a defrost mode where the condenser is heated to melt any ice. The melted water is collected internally and evaporated. After the defrost mode is completed, (about 8 min's ) the cycle repeats.
Four lights are mounted on the top of the Black Max case to indicate the operating mode. A power on light illuminates when 110v AC is available. The unit requires about 60 watts of power. The second light turns on whenever the thermoelectric cooler is running. The third light illuminates when the pump is running, and the fourth light turns on when the unit is in the defrost mode. The system also incorporates a temperature interlock to prevent high humidity air from being pumped into the engine, should something in the system fail. If the temperature of the condenser rises above a set value, the unit will automatically shut down. When this occurs, the fan and the cooler will turn off, and the cooler indication light will flash, alerting of the shutdown. The system will stay in the shutdown mode for about 30 mins. After this time, the system will attempt to restart the cooling cycle
The unit will operate continuously without maintenance. Nothing is attached to the engine, and it does not require any aircraft modification, or FAA approval. At the end of a flight, simply insert the adaptor into the engine breather, plug the system into an electrical outlet, and go home knowing that your engine is protected while you are not flying.
