The Flowserve NX Seal Cooler is a compact shell‑and‑tube heat exchanger with easy‑access cleaning, high‑temperature fittings, and ASME‑compliant design.
The NX Seal Cooler provides efficient heat removal for process or barrier fluids while cooling water circulates in the shell, minimizing scaling and fouling. Its compact design includes an integral mounting bracket, easy‑access coil cleaning with a single bolt, and options for vertical or horizontal installation, making it suitable for limited‑space applications.
The unit is built with 304 stainless‑steel tubing, 316 stainless‑steel fittings, and carbon‑steel shells and plates (painted). It meets ASME Section VIII‑1 and PED standards and offers a range of tube diameters, cooling areas, and pressure‑temperature ratings to suit various industrial needs.
| Tube OD | 0.500 in, 0.625 in, 0.750 in |
|---|---|
| Effective cooling area | 1.75 ft², 3.5 ft², 5.8 ft² |
| Max. temperature – tube side | 800°F (427°C) |
| Max. temperature – shell side | 212°F (100°C) |
| Materials of construction – tubing | 304 stainless steel |
The cooler can be mounted vertically or horizontally based on application conditions and orientation constraints.
Only one bolt fastens the shell, providing easy access to the coil for cleaning.
It is designed in accordance with ASME Section VIII‑1 and PED.
