What products does HK Dongda Supply Chain Limited supply?

We supply water cooled ice bath chillers from 0.3HP to 1.5HP, all-in-one cold plunge units in stainless steel and acrylic, far infrared sauna blankets, portable sauna tents and steam bath boxes, and infrared heating mats including red light and PEMF models.

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

Yes. Our design team supports logo application, pattern and colour design, retail packaging and structural customization, such as our 0.5HP customized chiller with 1000 L/H flow and a 4-point outlet design.

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.

Product Description

Frequently Asked Questions

Q: What is the difference between a traditional sauna and a far infrared sauna box?

Far infrared sauna boxes use specialized heating elements to emit infrared light waves that heat your body directly rather than simply raising the ambient air temperature. This allows for deep tissue penetration, gentle warmth, and effective sweat production at lower, more comfortable temperatures.

Q: How does PEMF therapy work inside a sauna blanket?

Pulsed Electromagnetic Field (PEMF) technology works in synergy with far infrared heat. While the far infrared rays deliver soothing heat to relax muscles and stimulate circulation, PEMF emits low-frequency electromagnetic waves to recharge and rejuvenate cellular vitality.

Q: How do I clean and maintain a portable sauna blanket or steam box?

After every session, unplug the device and let it cool completely. Wipe down the interior surfaces using a clean, damp cloth and a mild non-toxic cleaner or towel. Ensure all moisture is dry before folding or storing the unit away.

Q: How long should a typical sauna session last?

For beginners, sessions lasting 15 to 20 minutes at moderate temperatures are suggested. As your body adapts, sessions can be extended to 30 to 45 minutes, always ensuring adequate hydration before, during, and after use.

Q: Why is the R290 refrigerant significant in cooling and UV models?

R290 is a high-efficiency hydrocarbon refrigerant known for having near-zero ozone depletion potential (ODP) and an extremely low global warming potential (GWP), meeting stringent North American and European ecological compliance standards.
