Keep aquarium water and hydroponic nutrient solutions at a more stable temperature with the Hailea HC-100A Water Chiller. Designed for systems with a recommended cooling capacity of up to 100 litres, this compact chiller provides electronically controlled water cooling for aquariums and hydroponic reservoirs.

The HC-100A features a durable metal chassis, a digital temperature display and a corrosion-resistant titanium heat exchanger. It uses R134a refrigerant and is designed for continuous operation, making it a practical choice for maintaining controlled water temperatures in suitable freshwater, saltwater and hydroponic systems.

Precise digital temperature control

The electronic temperature controller allows you to set and monitor the water temperature, with the digital display showing adjustments in 0.1°C increments. This makes it easier to monitor your system and maintain a consistent temperature setting.

The chiller can operate down to approximately 4°C, subject to operating conditions and the requirements of the connected system.

Suitable for aquariums and hydroponics

The Hailea HC-100A is designed for smaller water-cooling applications, including:

• Freshwater and marine aquariums

• Hydroponic nutrient reservoirs

• Water circulation systems requiring controlled cooling

• Other compatible small-volume water systems

Its titanium heat exchanger is suitable for use with freshwater and saltwater applications. The recommended cooling capacity is approximately 100 litres, although actual cooling performance depends on ambient temperature, starting water temperature, installation conditions and the heat entering the system.

Technical specifications

Installation and operation

The HC-100A operates as part of a circulating water system and requires a suitable external pump to move water through the chiller. Select a pump and plumbing arrangement that provide a flow rate within the recommended 200–1,000 litres per hour range.

Allow sufficient ventilation around the unit and install it in a location where warm air can disperse freely. Cooling performance depends on the surrounding temperature, water volume, pump selection, circulation system and other sources of heat.

Please note: The HC-100A is designed for water systems of approximately 100 litres. It is not a one-size-fits-all solution for larger aquariums or reservoirs. For larger systems, consider a higher-capacity model from the Hailea HC range.
