Johnson Controls is testing a hybrid cooling system that promises to reduce environmental impact, lower operating costs and increase the resiliency of critical operations.

Used in conjunction with a traditional cooling tower, BlueStream uses a thermosyphon process in which refrigerant circulates naturally, with no need for a pump or compressor. Intelligent, web-connected controls coordinate the operation of both the wet and dry system components and adjust in all weather and thermal load conditions for optimum efficiency. This means the system utilizes wet cooling when it is hot and dry cooling when it is not.
