| Pure-water cooling units | units for high-voltage/high-power inverters and flexible AC transmission systems | Provides low-conductivity cooling for electrical power equipment |
| Special heat exchangers | stainless-steel tube heat exchangers, copper tube heat exchangers | Transfers thermal energy in industrial cooling loops |
More detailed product disclosures from market listings show that Tongfei also offers cabinet CDUs, in-rack and in-row CDUs, dry coolers, precision air conditioners, rear-door heat exchangers, manifold assemblies, and modular data-center cooling systems. This indicates a move beyond discrete chillers toward system-level thermal integration for industrial and digital infrastructure customers.
From a technical perspective, these products are used where stable operating temperature, controlled humidity, and electrical insulation are critical, including laser processing, inverter cooling, and electronics enclosures. Some product descriptions also indicate specialized designs for immersion cooling, fluorinated-liquid cooling, and cabinet-level liquid cooling, which are increasingly relevant in data-center and power-electronics applications.
