Which domestic spiral plate manufacturer is of better quality?

Thread Content

There’s a project for which I’d like to get a quote. Name: Heat exchanger
Structure type: Vertical spiral plate heat exchanger
Quantity: 1 unit
Thermal load: 150 kW

The main operating parameters are as follows:
| Item | Hot fluid side | Cold fluid side |
|------|----------------|-----------------|
| Medium name | Propylene gas | Chilled water |
| Composition | Propylene: 85 v%, Nitrogen: 15 v% | Water |
| Operating pressure (MPag) | 1.7 (maximum 2.2) | 0.1 (maximum 0.3) |
| Inlet temperature (°C) | 25 | 5 |
| Outlet temperature (°C) | 8 | 10 |
| Mass flow rate of medium (kg/h) | 2500 | 20000 |
| Volume flow rate of medium (m³/h) | 45 (at inlet conditions) | 20 |
| Phase state of medium | Gas phase fraction: 63% at inlet, 25% at outlet | — |
| Medium density (kg/m³) | 55 (at inlet conditions) | 1000 |
| Corrosiveness | None | None |
