The are a number of different EcoCooling control systems available when choosing the right evaporative cooling system. Small EcoCoolers (coolers with fans) come with a 5-speed wall controller as standard, the larger one with a 2-speed. For more complicated systems which require EC fan, dampers or recirculation control, a CREC system should be accounted for. The CREC system was originally designed for use in data centres, however, due to the low cost of components, has now become a viable option for industrial installations which require additional functionality (e.g. gyms/leisure/pharmaceutical warehouses).
