Mid-Range Ice Bath Chiller 2.0HP

The Sisu Ice Bath Chiller 2.0HP is our most powerful chiller — built for commercial environments, XL tubs, and any setup where fast cooling and quick recovery between sessions are essential.

With 5,000W of cooling capacity (variable up to 6,550W), the inverter compressor adjusts output based on demand — ramping up to cool down quickly, then backing off to maintain temperature quietly and efficiently. This makes it equally capable of powering a busy gym's cold plunge room or keeping a large home ice bath at target temperature throughout the day.

The heating function delivers up to 5,800W (variable to 7,560W), making this unit a genuine dual-purpose system for contrast therapy protocols. Set your target anywhere from 3°C to 42°C using the TFT touchscreen on the unit, or control it remotely via the Tuya Smart app.

An internal water filter keeps debris out of the system, and ozone disinfection is available as an optional add-on to extend water life between changes. Quick-connect fittings on the hoses make installation and disconnection straightforward — no tools required for the water connections.

Compatible with any ice bath tub that has inlet and outlet ports. Also works with tubs without ports — see the installation section below for the alternative method. Transport wheels and carry handles make positioning manageable despite the 50kg weight.

Installation

Important: After transportation, leave the chiller upright on a stable surface for 24 hours before first use to allow the refrigerant gas to settle.

Tubs with inlet and outlet ports (standard setup)

• 1. Place the chiller on a stable surface near the tub, at the same level as the bathtub
• 2. Install the filter lid on top — ensure it is hand tight
• 3. Ensure the built-in filter is installed
• 4. Install the valves on the tub's inlet and outlet — ensure hand tight
• 5. Connect the water pipes between chiller and tub using the quick connectors — chiller inlet to tub outlet, chiller outlet to tub inlet
• 6. Fill the tub — water level must be higher than the chiller inlet and lower than the tub inlet
• 7. Plug in and switch on the RCD, then power on the chiller
• 8. Check the water flow reading on the touchscreen — it should be higher than 15L/min
• 9. If both tub ports are below water level and water flow is low, open the drainer briefly to release trapped air, then close it

Tubs without inlet and outlet ports

• 1. Place the water inlet hose at least 10cm below the water level in the tub
• 2. Open the filter cup on top of the chiller and add 500–1,000ml of water to prime the pump
• 3. Close the filter cup tightly to prevent air leakage
• 4. Power on — if a water flow fault appears, repeat the priming step

Important Notes

• Maintain at least 100cm clearance on all sides of the chiller for airflow and ventilation
• Do not install in enclosed spaces such as cupboards, closets, or storage cabinets
• The chiller must be grounded before use
• Test the Residual Current Device (RCD) at least once a week
• Turn off the chiller before entering the ice bath
• Do not extend the water hoses — longer hoses reduce flow rate and cooling efficiency
• Ensure the power socket and chiller do not come into contact with water while the tub is in use

Filter Maintenance

• Replace the paper filter element when it becomes dirty or when a water flow warning appears on screen. Check the filter first whenever water flow drops below 14L/min.
• Clean the built-in mesh filter once a month — open the lid with the wrench, remove the mesh filter, rinse under running water, replace, and tighten. Close the tub valves before cleaning.
• Always power off the chiller and switch the RCD to OFF before replacing filters or cleaning the built-in filter.

Every 3 Months

• Clean the dust-proof net (condenser) to maintain cooling and heating efficiency. This is the single most impactful task for chiller longevity.

General

• Never clean the chiller with bleach-based detergents
• Do not put corrosive disinfectants (such as chlorine tablets) into the water
• Always disconnect from power before any maintenance or cleaning
• Never put the chiller outside in temperatures below 1°C when it has water inside
• When not in use for extended periods, open the drain outlet to empty all water from the chiller and hoses
• Do not place the chiller in direct sunlight or rain — use a shelter or our timber weather box
• Do not spray water directly onto the chiller unit
• Keep the chiller upright at all times — never invert

Q: What size ice bath does this chiller suit?

A: The 2.0HP is designed for commercial and XL setups. It handles large double-person tubs, plunge pools, and high-traffic commercial environments where multiple sessions run back-to-back throughout the day. For standard home tubs (300–600L), the 1.0HP is usually sufficient.

Q: Can I use this chiller with any ice bath tub?

A: Yes. It connects directly to tubs with inlet and outlet ports via the included quick-connect fittings. For tubs without ports, use the over-the-rim hose method — instructions are included above and in the user manual.

Q: Does the chiller also heat water?

A: Yes. The temperature range is 3–42°C with up to 7,560W of heating capacity, so it functions as both a chiller and a powerful heater. This makes it well suited to contrast therapy protocols.

Q: How loud is it?

A: The inverter compressor adjusts its speed based on demand, so it runs quieter than you might expect for a 2.0HP unit — especially when maintaining temperature. During active cool-down it's comparable to a standard air conditioning outdoor unit. For commercial installations, positioning the chiller in a plant room or utility area is recommended.

Q: How often do I need to change the water?

A: Every 2–4 weeks with regular filter maintenance. Commercial environments with heavy daily use or multiple users will need more frequent changes. If ozone disinfection is installed, water stays cleaner for longer. Requiring users to shower before entering extends water life significantly.

Q: What power supply does it need?

A: 220–240V / 50-60Hz — standard Thai power. The unit draws up to 12.2A (approximately 1,950W typical). Check that your circuit and socket can handle the load — a dedicated circuit is recommended for commercial installations.

Q: Can I install this outdoors?

A: The chiller is IPX-4 rated, but we still recommend keeping it protected from direct rain and sunlight. A covered area, weather shelter, or our timber weather box provides the best protection. Ensure adequate ventilation — do not enclose the unit.

Q: What does the WiFi app do?

A: The Tuya Smart app lets you monitor water temperature, set target temperature, adjust ozone timing, schedule power on/off times, and control the unit remotely. Available on iOS and Android. Note: the app only supports 2.4GHz WiFi networks.

Q: What's the difference between the 1.0HP and 2.0HP?

A: The 2.0HP has roughly double the cooling capacity (5,000W vs 2,450W) and significantly more heating power (5,800W vs 3,270W). It cools faster, recovers quicker between sessions, and handles larger volumes. The 1.0HP is more compact, lighter, and draws less power — better suited to home setups. For commercial environments, the 2.0HP is the recommended choice.

Q: Is ozone disinfection included?

A: Ozone disinfection is available as an optional add-on for this model. If installed, the ozone cycle runs automatically and can be adjusted from 0–5 minutes via the touchscreen or app.

Q: Is this chiller suitable for commercial use?

A: Yes. The 2.0HP is built for commercial environments with ETL, PSE, CE, SAA, IPX-4, FCC, and RCM certifications. The inverter compressor handles continuous duty cycles, and the 6,550W peak cooling capacity ensures fast recovery between sessions in high-traffic facilities.

Q: What warranty is included?

A: 1-year warranty on electrical components with replacement unit delivered to your location. 1-year structural warranty. Coverage excludes normal wear, unauthorised modifications, or accidental damage.
