The Ultra Cedar External Cold Plunge with 4HP Chiller & Integrated Filtration delivers professional-grade cold water therapy with powerful, efficient cooling and refined craftsmanship. Featuring up to 10,000 watts of cooling power, this system rapidly chills its 800-litre capacity to 4ºC (39°F), making it ideal for 2–4 users in both residential and commercial wellness environments.
Manufactured by iCoolsport in Australia, this enhanced external chiller configuration connects to a Turbo Mini Chiller that can be positioned up to 30 metres away for flexible installation. Optional sanitisation equipment can be seamlessly integrated into the return plumbing line for enhanced water clarity and hygiene.
The tub is constructed from hand-moulded insulated fibreglass with a smooth, low-maintenance interior, while the natural cedar cladding adds warmth and sophistication to any spa, recovery room, or outdoor wellness space.
Designed for reliability and ease of use, the Ultra system is capable of 24/7 operation and can cool water from ambient temperature to optimal cold plunge levels in as little as 1–2 hours. The included 15-inch remote touchscreen can be wall-mounted for convenience and connects to smart devices for effortless control and session customisation.
One-touch start functionality ensures your plunge is ready when you are, delivering consistent performance for recovery, circulation support, and cold exposure protocols.
