Offering the sector highly efficient, long-lasting solutions with products developed specifically for cooling towers operating in harsh environmental conditions, Dişsan Redüktör meets the particular needs of cooling towers with an engineering-led approach through its DKS and DNMF1 Series gearboxes.
Developed for this application area, the DKS Helical Bevel Gear Cooling Tower Gearbox and the DNMF1 Parallel Shaft Geared Motor Cooling Tower Gearbox models can operate across a very wide nominal torque range. Supporting motor powers over a broad range – 5.5–400 kW for the DKS and 4–55 kW for the DNMF1 – these systems are designed and manufactured in accordance with the CTI STD-111 standard. The gearbox housings are made of cast iron, while the gears are manufactured from high-quality alloy steel. This ensures both a long service life and high efficiency.
The tapered roller bearings used in Dişsan’s gearboxes are selected to provide a service life of 100,000 hours, while high-quality oil seals are used on the input and output shafts to prevent oil leaking out and dust, steam and the like getting in. In these products, which use oil-bath splash lubrication or, at higher powers, a pump-driven forced lubrication system as standard, optional features can include a backstop, oil level switch, oil temperature sensor, vibration sensor, pressure sensor, thermostatically controlled oil heater, oil dipstick and oil pump.
Notable for their quiet, vibration-free operation, these systems work in full harmony with Dişsan’s domestic engineering and offer users operational advantages thanks to their low maintenance requirements and long service life.
