Jumbo Cooler fluid coolers are intended for cooling process water in industrial, commercial, and free cooling applications, and features the benefits of evaporative cooling with water recirculation, thus minimizing energy and water consumption and offer increasing free cooling hours.
Jumbo Cooler units are equipped with evaporative pads wetted via the water distribution system to pre-cool the air before passing through the heat exchanger coils. This increases the amount of heat the air can extract from the coil and, in turn, increases the cooling capacity of the unit.
Evaporative cooling takes advantage of using water for humidification of warm and dry air and leads to significant energy savings in data center applications.

It is ideally suited to the requirements of mission-critical applications like data centers, telecom facilities and clean rooms, and in every area where reliability is a crucial factor.
Due to its excellent efficiency at part-load conditions, the Lighstream Turbo chiller is a brilliant economy solution for applications where the heat load is not constant or expected to increase.
The cost of mission-critical facility failure is huge and constantly increasing. The standard practice for most cooling facilities provides real-time management and monitoring of critical process equipment, but low tiered equipment is deemed too difficult to monitor. However, these uncontrolled equipment assets may cause a serious cooling process disturbances and loss of efficiency. The best method of equipment failure prevention is to institute a preventive maintenance program.
