Lightstream Freecool



New fluid coolers to be available in Q4 2016

September 30, 2016


Jumbo Cooler fluid cooling units intended for use in freecooling applications, such as data centers, process cooling, and healthcare, and features the benefits of adiabatic cooling with water recirculation, thus minimizing energy and water consumption and offer increasing freecooling 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 pads are made from cellulose impregnated with resins and biocide and antibacterial agents to prevent bacterial growth. Cross fluted, unequal angle pad design promotes the highly turbulent mixing of air and water for optimum performance. This unique design also functions to continually direct more water to the air entering surface of the pad, where the most intense evaporation occurs.

Customers of Jumbo Cooler can benefit from efficient and quiet large-diameter EC fans and reduced unit maintenance cost.


We made available a number of connectivity options, including Modbus, Echelon, Bacnet and KNX that allow the customers to monitor and manage their cooling facility to suit their requirements. Large-diameter EC fans and highly efficient heat exchangers provide cooling capacities up to 2.3MW on the small footprint and allow customers to save expensive facility space.


Jumbo Cooler unit is ideal for most mission-critical applications in terms of energy efficiency and reliability, whether installed in hot and humid climate zones or high pollution or seashore areas.

Jumbo Cooler will be available for orders in October 2016.
