CHV MECHANICAL SPEED VARIATOR: Chiaravalli CHV mechanical speed variators are oil-bath continuously variable transmissions in which torque transfer is carried out by means of friction discs, placed between the electric motor and the transmission. The CHV series delivers a stepless speed variation range of 1:5 — using a standard 1400 rpm motor, output speed ranges from 150 to 1000 rpm — with uniform, silent operation and growing torque at low speeds. The compact aluminium housing with B5 input and output flanges is suitable for use in harsh environments including chemical plant, outdoor processes and high humidity conditions. A cost-effective mechanical alternative to electronic inverters for applications requiring smooth, continuous speed adjustment such as pumping and mixing.
