Are your water chillers compatible with US and European power supplies?

Our 1.5HP ice bath water chiller is available in 110V and 220-240V versions to match North American, European and Asian power grids. Please confirm voltage and plug standard when ordering.

What refrigerants do your chillers use?

Our chillers use eco-friendly R290 or R32 refrigerant, aligned with European and US environmental policies for low global-warming-potential cooling.

How do I choose the right chiller horsepower for a cold plunge tub?

Chiller sizing depends on tub water volume, ambient installation temperature, target water temperature, usage frequency, local voltage and tub insulation. Home tubs are usually served by 0.3HP to 0.5HP units, while multi-user commercial recovery centres typically need 1.5HP. Share these data points and our engineers will recommend a matched model.

Frequently Asked Questions

Q: What is the difference between wet steam boxes and far infrared sauna blankets?

Wet steam bath boxes utilize heated water vapor to create a high-humidity environment for respiratory clearing and skin hydration, whereas far infrared blankets use direct light energy to penetrate deep into muscles for detoxification and joint relief at lower ambient air temperatures.

Q: How does red light therapy enhance the steam bath experience?

Red light technology penetrates the dermal layers to stimulate cellular repair and collagen production, amplifying the natural circulation-boosting and skin-rejuvenating effects of the traditional steam bath.

Q: Are the far infrared sauna blankets suitable for home use?

Yes, these blankets are engineered for both home and spa use. They are fully portable, easy to fold for compact storage, and crafted from durable PU leather that is simple to wipe clean and sanitize after each session.

Q: What size options are available for the sauna blankets and steam boxes?

The wellness equipment comes in several standard ergonomic configurations, including compact single models, extended spectrum blankets measuring up to 180×210 cm, single-zipper 180×160 cm models, and dedicated double-capacity enclosures.

Q: How do I properly maintain and clean the Body Photon Therapy Mat?

Ensure the mat is unplugged and completely cooled before cleaning. Wipe the surface using a soft damp cloth with a mild disinfectant solution, avoid harsh abrasive chemicals, and let it air-dry thoroughly prior to folding or storage.
