Stainless steel heat exchangers 4000 Series are ideal for applications where deionized water or corrosive fluids are used, and a high efficiency, compact unit is required.
The 4000 Series heat exchanger is our highest performing stainless steel tubed heat exchanger. It is ideal for applications where deionized water or corrosive fluids are used, and a high efficiency, compact unit is required. The heat exchanger has a superior construction with 316L stainless steel tubing expanded into copper cooling fins. The all-welded, argon-purged joints of the heat exchanger maximize its internal cleanliness, the pre-cleaned internal surface eliminates fluid contamination, and the 0.028" (0.7 mm) wall tubing ensures fluid circuit durability. The 4000 Series heat exchangers are available in straight, beaded, or 37° AN flare fittings.
High cooling capacity in a small envelope: The 4000 series heat exchanger is engineered for performance. It has a high tube density for maximum heat transfer. Heavy-walled (0.028˝/0.7 mm), 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 further increase performance.
Compatible with deionized water and corrosive liquids: All the wetted surfaces in the 4000 Series are 316L stainless steel, so it is ideal for use with high purity and/or corrosive coolants such as deionized water.
Integrated fan plate for improved performance and convenience: The 4000 Series’ integral fan plate acts as a plenum to ensure uniform air-flow distribution through the core, thus maximizing performance. It also enables easy fan installation.
Rugged and reliable: The argon-purged welded stainless steel frame and fan plate offer durability and strength. 4000 Series heat exchangers are 100% leak tested to 150 psi (10.3 bar).
Aspen or 4000 Series?
The Aspen offers 80% of the performance of the 4000 Series at approximately 50% of the cost. Where high performance in a small envelope is required, the 4000 Series is the best option. However, when a slightly lower performance/size ratio is acceptable, the Aspen offers better value. The Aspen also has lower air and liquid side pressure drops.
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.
