Hailea HS-52A Water Chiller

Hailea HS-52A Water Chiller

Hailea HS-52A Water Chiller is an inline aquatic water chiller intended for aquarium and hydroponic cooling systems within the published 600-2,200 litre-per-hour circulation range. Its published maximum output is 600-2200 L/hour, with a refrigeration rating of 1/6 hp. This page identifies the exact model, duty figures and selection limits so it can be compared accurately with the other products in the range.

The product is supplied under its customer-facing manufacturer brand. The figures below come from the current 2026 supplier catalogue, supported by manufacturer guidance where a current technical page is available. Maximum figures are not the same as guaranteed installed performance: pipework, depth, pressure, media loading and maintenance all affect the result.

Who is the HS52A best suited to?

This model is best considered for aquarium and hydroponic cooling systems within the published 600-2,200 litre-per-hour circulation range. It sits standalone model in this supplier range. That makes it easier to judge whether it is a compact entry model, a mid-range choice or one of the higher-output options before comparing price alone.

Technical specification

Technical figures are nominal supplier ratings. The calculated 24-hour energy figure, where shown, is rated wattage × 24 hours and does not include tariffs or intermittent thermostat operation.

Understanding the published specification

The 600-2200 L/hour is the required circulation range through the heat exchanger, not the cooling capacity of the whole installation. The 1/6 hp must be considered with water volume, ambient temperature, lighting, pumps, target temperature and ventilation. Excessive or insufficient flow can both reduce effective heat exchange.

The catalogue specification for this exact model is 600-2200 L/hour 1/6hp. Where the page includes a calculated daily-energy figure, it is provided only to make continuous-running products easier to compare; it is not an electricity-cost estimate and does not replace the rated power shown above.

How to size this model correctly

Chiller capacity depends on system volume, ambient temperature, lighting and equipment heat, target temperature and ventilation. Flow rate alone does not prove cooling capacity, so calculate the heat load for demanding installations.

For critical livestock, treatment or commercial systems, allow spare capacity and consider redundancy. If the required duty is close to the model’s maximum, moving to the next size normally provides a more useful operating margin than running a smaller unit continuously at its limit.

Installation and commissioning

Installation format: External installation with the specified feed-pump flow and unrestricted ventilation. Keep access available for cleaning and servicing, use appropriately sized hoses or airline, and avoid unnecessary bends or restrictions. Aquatic electrical equipment should be protected by a suitable RCD and installed in accordance with the supplied instructions.

Confirm water flow before enabling cooling, check every hose connection for leaks and leave clear ventilation around the condenser. Measure system temperature independently and record normal inlet, outlet and ambient conditions for future comparison.

Commission the complete system by checking actual flow, pressure, water level or temperature at the point of use rather than assuming the headline maximum will be achieved. Recheck after filters, diffusers or pipework have had time to accumulate normal fouling.

Compatible system components

Use a clean, correctly sized feed pump and place the chiller where warm exhaust air cannot recirculate. Pre-filtration protects the heat exchanger from debris. Short, generously sized hoses reduce pump losses, and accessible isolation valves make servicing easier.

Compatibility should be confirmed from the complete installation: connection size, hose or airline bore, voltage, control method, permitted flow and future servicing access can all affect whether two individually suitable products work correctly together.

Maintenance and service life

Keep condenser ventilation clear, clean the water circuit and pre-filter, and check actual flow periodically. Restricted air or water flow reduces cooling performance and can shorten compressor life.

Record the installation date and normal operating performance. A visible reduction in output, increasing noise, rising temperature or repeated tripping should be investigated rather than compensated for by restricting or altering other parts of the system.

Performance checks and fault finding

Poor cooling can result from restricted water flow, blocked condenser airflow, high ambient temperature, an unrealistic set point or an undersized unit. Clean the water circuit and air intake before changing settings. Repeated alarms, icing or compressor cycling require investigation rather than continued operation.

Compare any suspected fault with the clean, newly commissioned condition. Changes across every outlet or return normally point to the main unit or a shared restriction; a problem affecting one branch is more likely to be local pipework, airline, a valve, diffuser or connected accessory.

Technical information sources

Core model figures were checked against the current 2026 supplier catalogue. Family features, installation points and application guidance were cross-checked against current manufacturer technical material where available.

Recommended circulation pump

For a straightforward dedicated installation, we recommend the Hailea HX-8820 Water Pump. Its published maximum flow is 1,950 L/h, which gives a practical starting point for this chiller’s recommended 600–2,200 L/h operating band.

Important: pump ratings are measured at little or no head. Hose length, lift, bends, fittings and equipment resistance reduce the actual flow. Use a bypass or control valve where required, and confirm the installed flow remains within the chiller’s stated range. Chiller selection must also allow for water volume, ambient temperature and total heat load.
