For your samples that bring a very high delta T service, Sentry manufactures 1/4" (TR series) and 3/8" (FR series) LONG tube coolers with internal cooling water side baffling.
Tube lengths come in 19ft, 38ft, and 50ft lengths. The tube is wound in a double helix to save space and increase cooling water turbulence.
Flow rates are typically 500-2500 cc/min.
Spirally wound Tube-in-Tube full counter flow heat exchangers are well suited for a variety of applications where low to moderate flow rates of moderate (up to 300F) temperature and/or high pressure fluids need cooling (or heating).
Applications include: sample cooling or heating, seal flush cooling, high pressure samples (CW side is good for high HP also), pilot plants, 0-5 gpm heat transfer services, dirty or slurry fluids.
For your samples that require a high sample flow rate (ie 0.5+gpm), Sentry manufactures a very efficient (yet compact) spiral tube heat exchanger.
Coiled design allows:
Thermal expansion without shell side expansion joint; temperatures to 1500°F.
Flow rates of 1/2gpm to 300 gpm.
Design Pressures to 10,000 psig.
