Frequently Asked Questions
What industrial installations are best suited for the 06TUA483 compressor?
The 06TUA483 is engineered for large air-cooled water chillers, central HVAC systems, and heavy-duty industrial process liquid chillers operating on R134a refrigerant.
How does the 1-5/8 inch economizer connection improve system cooling performance?
The large-capacity economizer port subcools liquid refrigerant before entering the main expansion valve, boosting total refrigeration capacity and COP without increasing motor electrical load.
What electrical grid configurations are supported by the 06TUA483 model?
It supports multi-voltage setups including 460V/230V at 60Hz and 400V/200V at 50Hz, providing broad compatibility across regional power grids.
Does Ruifujie support customized branding and nameplates for export orders?
Ruifujie supports full OEM customization, including multi-language metal nameplates and customized brand logos.
What trade delivery terms and transaction currencies apply to international orders?
