The Aspen® and 4000 Series stainless steel tubed heat exchangers are compatible with deionized water and corrosive fluids and designed for reliability.
The Aspen and 4000 Series tube-fin heat exchangers are ideal for applications where deionized water or corrosive fluids are used and a high performing heat exchanger is required. When a slightly lower performance/size ratio is acceptable, the Aspen offers better value - 80% of the performance of the 4000 Series at approximately 50% of the cost. The Aspen also has lower air and liquid side pressure drops than the 4000 Series. However, when high performance in a small envelope is required, the 4000 Series is the best option.
Engineered for performance: The Aspen and 4000 Series are both engineered for performance. Heavy-walled, seamless stainless steel tubes are expanded into copper fin with an extruded full collar. The copper fin and the excellent metal-to-metal contact between the tube and the fin collar ensure optimum thermal performance.
Compatible with deionized water and corrosive liquids: All the wetted surfaces in the Aspen and 4000 Series are 316L stainless steel, so they are ideal for use with high purity and/or corrosive coolants such as deionized water.
Rugged and reliable: The welded stainless steel frame and fan plate offer durability and strength. The Aspen and 4000 Series heat exchangers are 100% leak tested to 150 psi (10.3 bar). The Aspen has 0.020” (0.5 mm) wall tubing and the 4000 Series has 0.028” (0.7 mm) wall tubing.
Integrated fan plate for improved performance and convenience: The integrated fan plate acts as a plenum to ensure uniform air-flow distribution through the core, thus maximizing performance. It also enables easy fan installation.
Extremely clean (Aspen): With our Aspen Series, our proprietary manufacturing process expands the tubes into the copper fin without the use of oils and our liquid return design eliminates potential particle trapping sites, which can contaminate cooling fluid. Argon-purged welded joints further ensure cleanliness.
Standard heat exchangers can be purchased from our distributors. Lytron also accepts standard heat exchanger orders from OEMs for 10 or more heat exchangers and/or for prototyping purposes.
