Low-Pressure Circulation Barrel Pump Unit

Headline: Liquid Overfeed Excellence for Massive Industrial Cold Stores.

Description: Instead of relying on expansion valves, this unit uses mechanical pumps to overfeed liquid refrigerant (usually NH3 or Freon) directly into the evaporators, ensuring 100% of the coil surface is actively cooling.

Scenario Solutions: * Giant Cold Storage & Freezing Tunnels: Eliminates the "dry out" zones found in standard DX (Direct Expansion) evaporators. Increases overall evaporator heat transfer efficiency by 20-30% across massive facilities.

Technical Specs: Pump Flow Rate: 9 m³/h ~ 27 m³/h | Circulation Drum Volume: 1.5 m³ ~ 5.5 m³ | Refrigerant: Freon
