Far Infrared & PEMF
Direct-from-factory water cooled chillers, FIR blankets, and complete athlete cryo-immersion systems engineered for distributors and brand builders.
From makeshift ice dumping to active refrigeration closed-loop thermodynamic circuits: an authoritative analysis of modern recovery engineering.
Traditional cold water immersion depended on raw ice, causing severe thermal stratification where water warmed rapidly upon skin contact. Modern industrial water chillers deploy eco-friendly R290 or R32 refrigerant circuits coupled with high-efficiency titanium heat exchangers. Continuous water recirculation maintains stable target temperatures between 2°C and 45°C without manual ice intervention.
Commercial liability mandates uncompromising water hygiene. Modern filtered chillers integrate 20-micron pleated sediment filtration cores with internal UV-C germicidal sterilization chambers. The continuous ultraviolet exposure (254nm band) destroys pathogenic bacteria and algae DNA without relying excessively on corrosive halogens that damage skin, plumbing lines, or acrylic plunge tubs.
The wellness industry has rapidly evolved from single-modality cold immersion toward contrast therapy protocols—pairing sub-5°C ice baths with far infrared sauna blankets, portable sauna tents, and PEMF pulsed magnetic therapy. Sourcing both heat and cold modalities from a single manufacturing partner slashes supply chain friction, streamlines custom firmware, and assures cosmetic uniformity.

Engineered for commercial continuous operation, seamless retail assembly, and diverse multi-climate deployments.
High-traffic public facilities face rapid water degradation and thermal shock from 30+ immersions daily. Our 1.5HP commercial chiller system is calibrated with an expanded heat exchanger coil and commercial self-priming centrifugal pumps, achieving swift pull-down cycles and maintaining crisp 3°C water despite intense back-to-back usage loads.
Direct-to-consumer businesses thrive on drop-shipping resilience and simplified box counts. We engineer all-in-one drop-stitch inflatable cold tubs, acrylic plunges, and 0.3HP/0.5HP chillers packed in custom drop-tested foam cartons with pre-fitted quick-release hoses, international power adapters, and custom branded user handbooks.
Resorts demand whisper-quiet sound footprints under 52dB and luxury exterior aesthetics. Our integrated stainless steel (FUL-B) cold plunge tubs combine hidden acoustic damper panels, concealed plumbing conduits, and cedar or brushed gunmetal trim options to elevate guest contrast therapy experiences without intrusive mechanical noise.
Headquartered in Hong Kong with dedicated industrial assembly facilities in Guangzhou, we assure seamless customs clearance across Western markets.

Navigating cross-border medical, electrical, and environmental product policies demands flawless paperwork. Our production facilities maintain active compliance credentials:
From conceptual engineering and industrial CAD drawings to production tooling and serialized QC.
Clients define targeted operating thermal range, dual-voltage specs (110V/60Hz or 220-240V/50Hz), tub volume, compressor decibel maximums, and target landing cost.
Our engineering department delivers 3D structural CAD blueprints, liquid thermodynamic simulations, custom chassis sheet metal cut-outs, and functional pilot testing units within 14 days.
Every production run undergoes a stringent 48-hour continuous cycle burn-in test, electronic grounding checks, high-pressure helium refrigerant leak tests, and flow-rate verification.
Anticipating energy efficiency mandates, smart IoT device telemetry, and sustainable cooling solutions.
Next-generation filtered chillers will integrate built-in turbidity sensors, ORP (oxidation-reduction potential) probes, and WiFi/BLE telemetry. Commercial facility managers can monitor water clarity, filter saturation levels, and compressor duty cycles in real time via proprietary cloud dashboards.
Transitioning from fixed-frequency cycling to DC inverter technology reduces startup current spikes by 60% and cuts continuous holding power consumption in half. This enables silent whisper-quiet indoor operation below 48dB and permits off-grid operation via lithium power stations.
In response to expanding EU F-gas phase-downs and US EPA SNAP regulations, Dongda is leading the standard adoption of ultra-low GWP R290 (propane-based hydrocarbon) chillers. Our systems offer superior thermodynamic latent heat properties with negligible environmental footprint.
Everything you need to know about lead times, installation sizing, filtration protocols, and cross-border logistics.
For commercial facilities handling back-to-back plunges in basins between 400L and 800L, our 1.5HP dual-thermal water chiller is strictly advised. Smaller 0.3HP to 0.5HP chillers excel in residential environments with 1-2 daily sessions, but commercial loads introduce significant continuous ambient heat transfer requiring the robust cooling capacity of a 1.5HP unit.
Water is drawn from the plunge tub through an external particulate catch screen into an internal 20-micron high-density pleated sediment filter. The water then circulates past a high-intensity 254nm germicidal UV-C bulb before entering the titanium heat exchanger. This dual-barrier setup eliminates hair, particulate debris, and biological contaminants without producing toxic chloramines.
Yes. Our commercial chillers feature IPX4 weather-rated structural housings with anti-corrosion galvanized powder-coat finishes or brushed 304 stainless steel. Electrical compartments are sealed against incidental moisture and dust ingress. In sub-freezing winter weather, our chillers can be configured with automatic anti-freeze cycling to circulate warm water through external plumbing, preventing cracked pipes.
Pre-production evaluation samples are typically completed within 7 to 10 working days. Full container orders (20GP or 40HQ) maintain a stable factory turnaround of 25 to 30 days. Backed by our 200+ person Guangzhou assembly workforce and monthly output capacity exceeding 600,000 thermal units, we guarantee prompt delivery cycles even during peak Q3/Q4 retail stocking windows.
High-specification wellness hardware, all-in-one acrylic tubs, far infrared cabins, and portable contrast recovery gear ready for international export.
