Which certifications are available for your products?

We hold certifications and audits from SGS, CTTC, BSCI, ISO, OEKO-TEX and GRS. Applicable models such as the FUL-B stainless steel cold bath tub carry CE, FCC and RoHS certification. Documents can be requested per SKU.

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

What is the difference between a steam bath box and a far infrared sauna?

A steam bath box uses moist heat generated by boiling water to create high humidity and warm temperatures, whereas a far infrared sauna uses dry light waves that penetrate deeper into muscular tissue at lower, more manageable ambient temperatures.

Can two adults comfortably fit in the dual-person sauna and steam boxes?

Yes, models such as the Double Steam Bath Box and the Infrared Dual-Person Sauna Box are specifically engineered with spacious interiors and reinforced seating to provide ample room for two adults at the same time.

What makes the 0.5HP water chiller eco-friendly?

The 0.5HP chiller utilizes R290 refrigerant, a natural hydrocarbon with zero ozone depletion potential (ODP) and ultra-low global warming potential (GWP), fully compliant with European and American environmental standards.

Is the Far Infrared Velcro Sauna Blanket portable and easy to clean?

Yes, the sauna blanket is lightweight, easy to fold, and features high-grade waterproof interior materials that can be easily wiped clean with a damp cloth after each thermal session.

Are standard home electrical outlets compatible with these sauna units?

Most portable sauna boxes and blankets are designed for plug-and-play operation using standard residential 110V or 220V power supplies, requiring no specialized commercial electrical installations.
