THROUGH THE Cultivator's LENS Hands-On Evaluation

Who This Is For

  • You are upgrading your reservoir cooling because rising nutrient temperatures are causing root rot and low oxygen.
  • You are moving to an active chiller because your 100 gallon system fluctuates too much for passive cooling to handle.
  • You are installing a high flow unit because your current setup chokes under the pressure of a 600 GPH pump.

What We Found

  • Always run a pump filter bag with this unit to keep biomass debris from clogging the titanium heat exchanger.
  • The 42 pound frame is heavier than cheap units, which keeps it from vibrating or walking across the floor.

What Users Say

  • Operators who swapped ice bottles for this chiller say they stopped seeing the temperature swings that stall growth.
  • Users tell us the digital LCD is easy to read from across the room, so they spend less time hovering over the tank.

EcoPlus 1/4 HP Water Chiller - Reservoir, Hydroponic & Aquarium Use

Temperature fluctuations above 75°F in reservoirs accelerate root disease, reduce dissolved oxygen, and stress aquatic life within a single grow cycle. The EcoPlus 1/4 HP Chiller maintains stable water temperatures in systems up to 100 gallons, delivering 360 watts of cooling power to protect hydroponic crops, reef tanks, and freshwater aquariums from heat-related failures.

This chiller features a titanium heat exchanger engineered to resist corrosion from concentrated nutrient solutions and saltwater while maximizing thermal transfer efficiency. The high-quality compressor operates at 3 amps, providing consistent cooling capacity without excessive energy draw. A micro computer with digital LCD display enables precise temperature setting and real-time monitoring, while 3/4 inch fittings accommodate higher flow rates for larger circulation systems.

The EcoPlus 1/4 HP Chiller works with pumps ranging from 264 to 660 GPH, supporting more substantial reservoir volumes than smaller models. The 17.13 x 11.61 x 18.5 inch footprint and 42.5-pound construction provide stable operation in commercial and advanced hobby setups. For optimal performance and equipment protection, pair this chiller with EcoPlus pump filter bags to prevent particulate buildup in the heat exchanger.

FAQs

What size reservoir can this chiller cool effectively?+

The EcoPlus 1/4 HP Chiller is designed to cool reservoirs up to 100 gallons. Actual performance varies based on ambient temperature, insulation, and heat load from lighting and pumps in your system.

Can I use this chiller with saltwater aquariums?+

Yes, the titanium heat exchanger is resistant to corrosion in both freshwater and saltwater environments, making it suitable for reef tanks, marine aquariums, and hydroponic systems with mineral nutrients.

What pump flow rate should I use with this chiller?+

The chiller requires a pump with a flow rate between 264 and 660 gallons per hour (GPH). Flows below this range may reduce cooling performance, while excessive flow may reduce efficiency.

Do I need to use a filter bag with this chiller?+

Yes, using an EcoPlus pump filter bag is recommended to prevent debris and sediment from entering the heat exchanger, protecting the chiller and maintaining cooling efficiency.

How do I set the target temperature on the digital display?+

The LCD control panel allows you to set your desired temperature using the front control buttons. The display shows both the current and target temperatures, and the chiller automatically maintains your setting.

What are the power requirements for this chiller?+

The unit operates on 120V at 60Hz and draws 3 amps (360 watts), offering strong cooling performance for mid-sized systems while remaining energy-efficient.

How much space do I need for installation?+

The chiller measures 17.13 × 11.61 × 18.5 inches and weighs 42.5 pounds. Allow additional space around the unit for proper ventilation and airflow.

What's the difference between the 1/10 HP and 1/4 HP chillers?+

The 1/4 HP model provides more cooling capacity (360W vs 264W), handles larger reservoirs (up to 100 gallons vs 55 gallons), requires higher pump flow rates (264-660 GPH vs 66-317 GPH), and uses 3/4 inch fittings instead of 1/2 inch.
