Active Aqua Water Chillers
Active Aqua Chillers are the Freon-free, environmentally safe way to keep hydroponic solutions at the perfect temperature in your reservoirs. With microcomputer control systems and LCD displays, as well as temperature memory systems included in each unit, these chillers offer maximum utility and durability.
Active Aqua chillers are environmentally friendly (they use R134a refrigerant) and are ideal for keeping the nutrient solution in your reservoir at the perfect temperature. Each unit has a user-friendly temperature system that allows you to control your desired temperature range as needed, and all models now have a boost function that accelerates the chilling process for quicker establishment of desired nutrient solution temperature.
