Cooling towers are found in major industrial and commercial facilities to extract waste heat into the atmosphere. Cooling towers are found in power plants, refineries and chemical plants. Smaller cooling towers are found at hospitals and universities. Most cooling tower systems have a motor driving a propeller shaft coupled to a gearbox. Some common problems include noise, vibration, erratic operations and not operating. CMT can repair the motor, gearbox or propeller shaft to get back up and running.
