Sanjiu mainly make evaporative cooling towers, but also dry air coolers. Evaporative wet cooling solution is more economical in both initial set up cost and operation cost, with minimal footprint for installation, while dry air coolers save water, and avoid freeze concerns during cold seasons. But dry coolers require much higher initial cost and consume more electricity power, take much bigger footprint. Besides, dry coolers are only recommended when the process fluids are of generally high temperature range.
So firstly it’s necessary to consider wet or dry cooling solution. It depends on many aspects but mainly two initial facts, water resources and fluids temperature.
When the location to install the tower is not rich or lack of water resources, or water cost is too high, our GKM air cooling series can be the first option, but the cooled water temperature can be only degrees higher than the environmental air temperature, otherwise additional chillers are required for further cooling.
In other cases, our GHM, GTM and GOM evaporative cooling series are much more suitable, with higher cooling capacity in general. GHM series are of closed loop cross flow type, widely applied as a reliable, efficient, economical, and clean solution for most of systems with requirements for heat rejection. GTM series are of closed loop counter flow type, work without any wet deck fills, thus more compact and more suitable for higher temperature ranges. GOM series are our open towers, most economical but the process water approaches the environment since of open loop, of larger capacity with module design.
However, there are more aspects to be considered for a most functional and economical cooling solution in each project. And we can always calculate efficiently and precisely from the data collected by above listed questions.
