Clutch The KTM 250 EXC-F employs the KTM-developed DDS clutch (damped diaphragm steel) with a wear-free steel basket and extremely heat resistant clutch plates and new, nitrated steel liners. This clever design employs a diaphragm spring instead of the usual coil springs, making for considerably easier clutch action.
The difference between active and passive solar water heating systems is that active systems have circulating pumps and controls, while passive systems do not. Although passive systems are usually not as expensive as active systems and can last longer, they are generally less eficient.
Unlike âmushroom-typeâ patio heaters, HEATSCOPE infrared radiant heaters generate heat directly. They have much lower operating costs, a broader heating coverage area, and generate significantly less CO2. Unlike âmushroom-typeâ patio heaters, HEATSCOPE infrared heaters spread their heat more evenly and are much more effective since they donât require liquid-gas containers that must be replaced regularly. They also emit no smells and no noise, because they operate with electricity (220-240 V AC, 50 Hz).
