Maintain controlled water temperatures in larger aquariums and hydroponic systems with the Hailea HC-500A Water Chiller. Designed for circulating water systems with a recommended capacity of approximately 500 litres, this powerful refrigeration unit helps manage water and nutrient solution temperatures in demanding installations.

The HC-500A features a robust metal housing, digital temperature control and a corrosion-resistant titanium heat exchanger. Using R134a refrigerant and a 1/2 HP compressor, it provides an effective cooling solution for suitable freshwater, saltwater and hydroponic applications.

Digital temperature control

The Hailea HC-500A features an electronic temperature controller and digital display, allowing you to monitor and adjust your system's water temperature. The display provides readings in 0.1°C increments, making it easier to monitor temperature changes and maintain your chosen setting.

The unit can operate at temperatures as low as approximately 4°C, depending on the installation and operating conditions.

Titanium heat exchanger for freshwater and saltwater

The HC-500A incorporates a titanium heat exchanger designed to resist corrosion in freshwater and saltwater applications. This makes it suitable for marine and freshwater aquariums, as well as hydroponic nutrient reservoirs.

Designed for larger water systems

The HC-500A is recommended for systems with a water capacity of approximately 500 litres. It is suitable for larger aquariums and hydroponic installations where maintaining a controlled water temperature is important.

Manufacturer testing specifies cooling 500 litres of water from 28°C to 18°C over 20 hours, with an ambient temperature of 30°C. A separate test with 1,000 litres reached 23°C under the stated conditions. Actual cooling performance will vary depending on ambient temperature, water volume, circulation, lighting, pumps and other sources of heat.

Technical specifications

Installation and operation

The Hailea HC-500A requires an external water pump to circulate water through the chiller. Choose a suitable pump capable of delivering a flow rate within the recommended 1,200–3,000 litres per hour range.

The pump and circulation system should be selected to suit the overall installation, including pipework, filters and other equipment. Ensure that the chiller receives an appropriate water flow during operation.

Install the unit in a well-ventilated location, leaving sufficient space around it for heat dissipation. Avoid enclosing the chiller in a cabinet or placing it somewhere warm air cannot escape, as this can reduce cooling efficiency.

For best results, consider the total water volume, ambient temperature, lighting, pump heat and other equipment that may increase the temperature of your system.

Please note: The 500-litre capacity is a recommended system size based on specified test conditions, not a guarantee of identical cooling performance in every environment. Larger water volumes and higher heat loads may require a more powerful chiller.
