SGS-Tested R-32 Industrial Chillers for North American Applications

As industrial equipment manufacturers place greater emphasis on safety, compliance, and reliable cooling, TEYU continues to expand its chiller portfolio for demanding markets.

10 TEYU CW and CWFL industrial chillers have been independently tested by SGS to applicable UL & CSA standards. All 10 chiller models use R-32 refrigerant and include configurations designed for North American industrial applications, providing cooling solutions for CO₂ lasers, CNC equipment, and 3–40kW fiber laser systems.

SGS-Tested to UL & CSA Standards
SGS is an internationally recognized testing and inspection organization. For these selected TEYU models, SGS testing provides independent verification against applicable UL & CSA safety standards, offering additional technical documentation for OEMs, system integrators, and industrial users evaluating cooling equipment for the U.S. and Canada.
Selected models support 230V/60Hz/1-Phase or 460V/60Hz/3-Phase power configurations, depending on the model. Applicable models also feature RS-485 Modbus RTU communication for industrial equipment integration.
Note: SGS testing applies to the specified chiller models and does not represent certification of an entire machine or system. Final equipment compliance depends on the complete system design and applicable requirements.

R-32 Low-GWP Refrigerant
All 10 SGS-tested chillers use R-32 refrigerant, a lower-GWP refrigerant increasingly adopted in modern refrigeration systems.
For North American equipment manufacturers, this combines independently tested safety requirements with a refrigerant option aligned with the industry's ongoing transition toward lower-GWP technologies.

CW Series Industrial Process Chillers
The SGS-tested CW Series includes:
TEYU CW-6000BNPTY-UL — 3140W cooling capacity, ±0.5°C
TEYU CW-6200BNPTY-UL — 5100W cooling capacity, ±0.5°C
TEYU CW-6260BNPTY-UL — 9000W cooling capacity, ±0.5°C
Designed for CO₂ laser systems, CNC machine tools, laboratory equipment, and industrial machinery, these industrial chillers feature intelligent temperature control, RS-485 Modbus RTU, an emergency stop switch, multi-level protection, and a sealed electrical junction box.

CWFL Series Fiber Laser Chillers
The SGS-tested CWFL Series chillers cover cooling fiber laser systems from 3–4kW to 40kW:
TEYU CWFL-3000BNPTY-UL — 9.1kW cooling capacity
TEYU CWFL-6000KNPTY-UL — 17.7kW cooling capacity
TEYU CWFL-12000KNPTY-UL — 35kW cooling capacity
TEYU CWFL-15000KNPTY-UL — 37kW cooling capacity
TEYU CWFL-20000KTPTY-UL — 45kW cooling capacity
TEYU CWFL-30000KTPTY-UL — 67kW cooling capacity
TEYU CWFL-40000KTPTY-UL — 85kW cooling capacity
The CWFL Series uses dual independent cooling circuits for the laser source and optics, with intelligent temperature control, RS-485 Modbus RTU, and multi-level protection. Applicable models also feature anti-condensation protection and liquid-level monitoring.
These industrial chillers are designed for demanding fiber laser cutting, welding, cleaning, cladding, and other high-power laser processing applications.

Why It Matters for North American Equipment Manufacturers
For U.S. and Canadian OEMs and system integrators, cooling equipment is part of the overall machine design. Relevant third-party testing and clearly documented specifications can help support:
* Equipment qualification with additional safety documentation
* System integration through defined electrical and communication specifications
* Project delivery with documentation relevant to North American applications
* Reliable operation through precise temperature control and multiple protection functions

Since 2002, TEYU has specialized in industrial cooling solutions, with a 50,000 m² production facility and 700+ employees serving customers worldwide.
The SGS-tested R-32 CW and CWFL models provide North American customers with application-specific cooling, independently tested UL & CSA safety requirements, and practical integration features for industrial and laser systems.
