240 Ton, Thermal Care #TXW-240, water-cooled chiller, R-22 dual, 120 HP hermetic screws, 2003

This Thermal Care TXW240 is a heavy-duty 240-Ton water cooled process chiller built for continuous industrial service. Manufactured in October 2003 (Serial No. 02111010310), this unit features a robust dual-circuit configuration with two independent 120HP RefComp hermetic screw compressors — providing redundancy and flexibility for large-scale process cooling applications. Thermal Care has confirmed the 240-ton capacity rating for this model.

A critical value-add on this unit: at least one of the two compressors was replaced in September 2015 (RefComp SRC-S-305-MZ H, Serial 15333299), significantly extending the useful life of the compression system well beyond the original 2003 manufacture date. The second compressor (RefComp SRC-S-305-LT, production date 06/2010) was also replaced after original manufacture, meaning both compressors are newer than the chiller frame itself.

The original Thermal Care TX Series operation and maintenance manual is present inside the control panel.

• 240 tons of water-cooled process cooling capacity — suitable for large plastics, food processing, pharmaceutical, chemical, or HVAC applications
• Dual independent refrigeration circuits — each circuit has its own compressor, expansion valve, and temperature control board, allowing partial operation or staged loading
• Both compressors are post-2010 rebuilds — not original 2003 compressors; the newest is a 2015 replacement, reducing the risk profile significantly
• Allen-Bradley electrical components — industry-standard, widely available contactors (100-D180) and control components
• Dual circuit temp control boards — individual temperature control for each refrigeration circuit
• Original manual on-site — supports commissioning, startup, and maintenance
