Madden Sample Coolers are miniature heat exchangers designed to reduce high temperature liquid samples to safe, usable temperatures for analysis.


• Available in copper and 316 stainless steel tube coil material. • Available in CS and 304SS Sch 40 pipe. • All designs disassemble with standard tools for easy cleaning or replacement of damaged coils. • Madden's wide variety of cooler designs offer solutions at many price points without compromising on construction and material quality like other competitor designs.

TYPE 1 (Compact): These sample cooler models have all the piping connections for the sample and the cooling water on the threaded cap on the top of the sample cooler. All coils are 1/4” OD tubing, and all piping connections are 1/4"NPT. Cooling water enters on the left and exits opposite on the right. Sample inlet connection is vertical on the top, and the cooled sample exits from the spout.

TYPE 2 (Cost Effective & Larger Capacity): These sample coolers offer both 1/4" and 3/8" OD tubing coils. Sample connections are 1/4" FNPT and are made on the top plate. Cooling water connections are 3/8" FNPT located on both top and bottom plates. Madden’s Type 2 design can offer up to 1" FNPT cooling water


1. Shell side of all units are rated to 300 PSI. 2. All units can be made with 304SS, designated with “A” at the end of the model number. For pricing on units with 304SS shells not specifically noted here, please contact the factory for pricing.
3. Coil side temperature ratings: Copper up to 400 deg F, 316SS up to 1,000 deg F. 4. Larger cooling water connections available for Type 2 coolers via CS, Class 150 half couplings: a. Add “-C1” to part number for ½” FNPT, “-C2” = ¾” FNPT, “-C3” = 1” FNPT.
b. Add $295.00 to the list price for (2) couplings of any size noted above in this section.

Typically, liquid grab samples can be cooled with 1.3 square foot coil surface area models. For continuous cooling, or for steam grab samples, 2.6 sf or
larger coil surface area is recommended.
