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.

Product Description

Frequently Asked Questions

Q What technologies are integrated into these wellness therapy mats?

These advanced therapy mats integrate a combination of Far Infrared (FIR) thermal therapy, Pulsed Electromagnetic Field (PEMF) technology, red light photon therapy, and natural gemstones like tourmaline and amethyst to deliver holistic body recovery.

Q How does Far Infrared (FIR) crystal heating benefit the body?

Far infrared rays penetrate deeply into muscle tissues and joints, gently elevating internal temperature, promoting microcirculation, relieving muscle stiffness, and supporting the body's natural relaxation processes.

Q Are these therapy mats compatible with international voltages?

Yes, models such as the FUL-8120 portable mat are designed for universal operation, supporting global voltage inputs ranging from 110V to 240V for convenient worldwide use.

Q Can the therapy mat be used every day?

Yes, these wellness mats are safe for regular daily sessions. Users typically start with 20 to 30-minute sessions at moderate temperature settings and adjust duration based on personal comfort and wellness needs.

Q How should I clean and maintain the therapy mat?

Unplug the device before cleaning. Wipe down the durable premium PU leather surface using a soft, slightly damp cloth with mild soap. Avoid soaking the mat or using harsh abrasive cleaners, and allow it to dry completely before storage.

Q What is the purpose of combining red light therapy with PEMF?

Combining red light therapy with PEMF provides dual-action support: red light photons target the surface and outer tissue layers to rejuvenate skin and cells, while PEMF waves reach deeper cellular structures to optimize energy flow and tissue recovery.
