Keeping your industrial air cooler in continuous service

Gearboxes for Cooling Towers and Air Coolers

It is our mission at BIS Both Industrial Services B.V. to supply you with only the best air cooler gearboxes for your project. We do this by thoroughly evaluating your project’s goals and requirements before selecting the most appropriate course and range of products accordingly. We supply an extensive range of right-angle air cooler gearboxes, including pump gear boxes, double reduction gearboxes, and parallel gearboxes specially designed for air coolers. A wide variety of extras can be included: monitoring sensors, switches, back stops, etc.

We supply highly durable gearboxes, of brands like Amarillo, Hansen, Flender and others, that show maximum performance even in demanding situations and require minimum maintenance. Our single reduction air coolers come in a wide range of standard ratios from 2:1 to 9.5:1, compatible with anything up to 15kW/1500RPM. The double reduction gearboxes are capable of meeting the power requirements of any cooling tower up to 335kW/1500RPM. These are available in ratios from 8:1 to 20:1.

We also carry a wide range of pump gearboxes, especially for fire fighting installations onshore as well as offshore, all of which come in a selection of ratios with different rotations of both ingoing and outgoing shafts.
