Tube-in-tube heat exchangers or coaxial heat exchangers consist of two tubes, an inner and an outer coiled together. This unique, compact design prevents thermal fatigue, increases efficiency and reduces the overall size. It is ideal for high temperature, high pressure and low flow applications such as water chillers and in.

Tube-in-Tube heat exchangers are specifically designed for uses in water cooled condensers, water chillers and in water source heat pumps. The design is being used by major OEM’s around the world and in the ever expanding wholesale replacement market. Simplicity of design and installation makes this product ideal in both markets.
