Do you offer OEM, ODM and private-label services?

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

How does far infrared technology work in sauna blankets and mats?

Far infrared rays penetrate deeply into skin tissues and muscle layers, producing gentle, therapeutic heat from within. This helps stimulate blood circulation, enhance relaxation, relieve tension, and promote natural recovery.

What are the main benefits of combining PEMF with Red Light Therapy?

Combining Pulsed Electromagnetic Field (PEMF) technology with red light therapy provides complementary benefits. Red light stimulates surface cellular vitality and tissue health, while PEMF works deeper to balance cellular energy, maximize pain relief, and accelerate wellness recovery.

Is the R290 refrigerant in the cooling chiller safe and compliant?

Yes, R290 is a natural, hydrocarbon refrigerant recognized for its zero ozone depletion potential (ODP) and extremely low global warming potential (GWP), making it fully compliant with stringent EU and US environmental standards.

How easy is it to set up and store the Quadrilateral Steam Bath Box?

The steam bath box features an intuitive, modular structure designed for quick assembly and disassembly. When not in use, it folds into a compact footprint for effortless storage in home and spa settings.
