Maintain controlled water temperatures in large aquariums and hydroponic systems with the Hailea HC-1000A Water Chiller. Designed for demanding water-cooling applications, this powerful refrigeration unit is suitable for aquariums and circulating water systems with a recommended capacity of approximately 1,000 litres.

The HC-1000A combines a robust steel chassis, digital temperature control and a corrosion-resistant titanium heat exchanger. Powered by a 1 HP compressor and using R134a refrigerant, it provides substantial cooling capacity for larger freshwater and saltwater aquariums, as well as compatible hydroponic reservoirs.

Powerful 1 HP cooling performance

The Hailea HC-1000A is designed for larger water systems where maintaining a stable temperature is important. Its 1 HP compressor provides considerably more cooling capacity than the smaller models in the Hailea HC range.

Manufacturer testing specifies the following performance under controlled conditions:

• 1,000 litres of water cooled from 28°C to approximately 14–16°C over 20 hours.

• 2,000 litres of water cooled from 28°C to approximately 21–22°C over 20 hours.

These results were recorded at an ambient temperature of 30°C. Actual performance will depend on installation conditions, water circulation, ambient temperature and the amount of heat entering the system.

Digital temperature control

The HC-1000A features an electronic temperature controller and digital display, allowing you to monitor and adjust the water temperature.

Its microcomputer control system includes temperature memory, allowing the chiller to resume its previous operating settings after a power interruption. The unit also incorporates an automatic overcurrent protection system.

Titanium heat exchanger for freshwater and saltwater

The chiller uses an anti-corrosive titanium heat exchanger designed for both freshwater and saltwater applications. This makes it suitable for large marine and freshwater aquariums, as well as compatible hydroponic water-cooling installations.

The robust steel housing is designed for long-term use in demanding environments.

Suitable for large aquariums and hydroponic systems

The HC-1000A is suitable for:

• Large freshwater aquariums

• Marine and saltwater aquariums

• Large hydroponic nutrient reservoirs

• Water-circulation systems requiring substantial cooling capacity

• Other compatible water-cooling applications

Although commonly positioned as a 1,000-litre aquarium chiller, manufacturer testing also includes a 2,000-litre water volume. The achievable temperature depends on the total water volume and heat load.

Technical specifications

Installation and operation

The Hailea HC-1000A requires an external water pump to circulate water through the cooling unit. Select a suitable pump and circulation arrangement capable of delivering a flow rate within the recommended 1,500–4,000 litres per hour range.

The circulation system should be selected to suit the complete installation, including pipework, filters and other connected equipment. Ensure that adequate water flow is maintained through the chiller during operation.

Install the unit in a well-ventilated location with sufficient clearance around the housing. The chiller releases heat into its surroundings, so restricted ventilation or an enclosed installation can reduce cooling efficiency.

For reliable performance, consider the total water volume, ambient temperature, aquarium lighting, pump heat and other sources of heat entering the system.

Please note: Cooling performance depends on operating conditions. The manufacturer's 1,000L and 2,000L test results were obtained under specified conditions and should not be treated as guaranteed temperatures for every installation. The unit also requires a suitable external circulation pump.
