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.
A solar hot water system consists of a geyser and solar panel. The combination of the two allows you to use the FREE energy from the sun to heat your water, thus enabling you to significantly cut down or in some cases eliminate the need for electrical or gas heating.he solar controller acts as a timer switch for your geyser. To maximize electricity savings, it only allows the geyserâs electrical element, to switch on in preset times, should the days solar energy not have provided enough energy to heat the water as required.
