ter is flowing through the cooling coil, certain amount of heat is transferred from the oil to the water and thereby removed from the system. 3, 2 3, 2 .. ..VX 1X Fig. 3: Cooling coil on gear unit of types .. and .. 1 Coolingwater connection 2 Reducing screw 3 Output shaft detailed view of the gear unit can be obtained from the drawings in the gearunit documentation. The water can flow through the gear unit in either direction. The pressure of the cooling water must not exceed 8 bar.If the gear unit is being withdrawn from service for longer period and if there is danger of freezing, the cooling water must be drained off. Remove any remaining water with compressed air. The ends of the cooling coil must never be twisted because this could destroy the cooling coil. The reducing bolt must not be tightened or demounted because this may result in damage to the cooling coil. Be especially careful when blowing with compressed air. Wear protective glasses! Avoid too high pressure on the coolingwater entry. For this coolingwater flow control must be used (.. pressure reducer or suitable valve). For connecting dimensions, refer to the dimensioned drawing of the gear unit. The required cooling water quantity and the max. permissible inlet temperature are given on the data sheet and/or the list of equipment. 4 / 1BA 5 en 0/2.8.3 Addon oilsupply system with air oilcooler For types H2.. and B2.., an oilsupply system with air oilcooler may be applied. This oilcooling system is permanently attached to the gear unit. Components: an air oilcooler flange pump coarse filter (double changeover filter from size pressuremonitoring device temperaturecontrol valve pipework The air oilcooler is designed to cool the gear oil by means of air from the surrounding atmosphere. Depending on the volume flow, the oil passes through the cooler in one or more streams and through the current of air blown in by the fan. For cold starts, bypass pipe with temperaturecontrol valve is
