Cooling Device - HCC | ADCA

ADCA HCC – Hot Condensate Cooler Vessel

The ADCA HCC is used in condensate lines where discharges from higher-pressure steam traps are routed to a lower-pressure, lower-temperature condensate header. The rapid pressure drop can generate flash steam; if this condenses suddenly within cooler condensate, it may cause noise, vibration, and water hammer.

Operating Principle

Hot condensate passes through an internal AISI 316L coil, while cooler condensate circulates around the coil via natural thermosiphon effect. Gradual cooling reduces flash steam bubble formation and collapse before final mixing in the condensate line.

Operating Limits

For HCC/S PN16: up to 16 bar at 50°C, 14.8 bar at 100°C, 13.3 bar at 200°C, 12.1 bar at 250°C. For HCC/S PN40: 40 bar at 50°C, 37.1 bar at 100°C, 33.3 bar at 200°C. Selection must consider pressure, temperature, and condensate expansion point.

Installation

Hot condensate from the steam trap connects to the horizontal coil inlet. Cooler condensate enters from below and exits vertically. Proper piping layout is critical for natural circulation and to prevent stagnant zones.

FAQ

When is HCC selected?
When water hammer is observed in condensate headers after discharges from higher-pressure steam traps.

Is this a sample cooler?
No. The HCC is a line condensate mixing/cooling device, not a sampling instrument.
