The Neptune Sample Cooler is designed to cool hot water or steam samples for easy handling and effective sample collection. The cooler can be applied to hot water, saturated steam, and/or superheated steam services.

Assuming a coolant inlet of approximately 55°F (12°C), an exit of approximately 120°F (50°C) and a sample exit of approximately 110°F (43°C), the cooler will provide performance approximately per the ranges described below:

Hot water samples:

  • At 250°F (120°C), approximately 1,500 CC/min of sample will be produced using 1 gpm (3.8 L/min) of coolant
  • At 700°F (370°C), approximately 950 CC/min of sample will be produced using 2-1/2 gpm (9.5 L/min) of coolant

Saturated steam vapor: The sample inlet and exit valves can be used to create various operating pressures in the cooler for producing samples from saturated steam vapor. 

  • At 175 psia operating pressure, 640 CC/min of sample can be produced using  approximately 3.0 gpm (11.4 L/min) of coolant
  • At 25 psia operating pressure, 300 CC/min of sample can be produced using  approximately 1.5 gpm (5.7 L/min) of coolant

Superheated steam: Maximum sample inlet temperature of 750°F (400°C).

  • 1,000 psia cooler operating pressure produces 640 CC/min of sample at 3.5 gpm (13.3 L/min) coolant flow
  • 20 psia cooler operating pressure produces 315 CC/min of sample at 1.75 gpm (6.6 L/min) coolant flow
