Cooling-tower drives
Right-angle bevel-helical drives built specifically for cooling-tower fans, with a long low-speed output shaft, upgraded corrosion protection and seals for the wet, warm plenum. Standard reducers fail early in that environment; the duty-built version is sealed and finished for it. SES holds the range as an authorised STM Team distributor, covering series RXO/TR cooling-tower duty; output Extended low-speed fan shaft; protection Special coating, upgraded seals, breather; cooling Sized for continuous fan duty. Executions include RXO/TR (cooling tower), RXP 800/CR (air-cooled condenser), with backstop. It is specified most often into cooling-tower fans and air-cooled condensers. Every part is genuine STM Team through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Cooling-tower drives in the parts of a plant where this particular duty actually occurs. In practice that means cooling-tower fans, air-cooled condensers, and equally evaporative coolers, process cooling plant. What links them is the duty rather than the machine name — base: Bevel-helical right-angle. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the STM Team range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Cooling-tower fan in a wet plenum — RXO/TR with tower-duty seals and coating Air-cooled condenser (ACC) — RXP 800/CR cooled variant Corrosive / coastal environment — Upgraded coating and stainless hardware Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Specify tower duty, not a standard bevel-helical — the seals, breather and coating are the whole point; add a backstop to stop reverse windmilling. Send the designation off the failed part and we will confirm the STM Team equivalent and stock position.
