Coaxial heat exchanger tubing has an advanced multi-spiral twisted configuration. This multi-spiral twisting features caused enhanced the heat transferring rate and decreased pressure drop which make coaxial heat exchanger is well applied to heat pump systems. The equal difference between the jacket tube and exchanger tube lets coaxial heat exchanger have a good oil collection when it is used as evaporator. Also, coaxial heat exchanger could be widely used in water chiller, water source heat pump, air source heat pump and geothermal heat pump.

Coaxial heat exchanger increased internal burst pressure and compression strength .

Coaxial heat exchanger reduced pressure drop, increased water turbulent mixing, inhibited the solid formation of liquids and increased the heat transferring rate when it is applied in water source heat pumps.

Coaxial heat exchanger could prevent water freezing when it is used as evaporator in water chiller.

Coaxial heat exchanger has a bigger diameter water channel. Thus it is not easy to block water flowing and suitable to lower water quality.

Coaxial heat exchanger is designed in plain tube ends for simply connection
.
Coaxial heat exchanger has a lower cost compared to other specialized heat exchanger tubing.

Coaxial heat exchanger could be made from stainless steel, titanium, and copper nickel alloy for the application in medical processing machines, food processing machines, marine water heat exchanging, chemical processing machine and other special industries. And it could be made from other metals according to customer's requirements.

Our patented technology imparts an enhanced surface configuration to any metal tubing. The process provides more surface area for a given length of tubing and creates a turbulent mixing action that results in vary high heat transfer through the tube walls. The heat exchanger co efficiency has increased up to 350% than smooth tubing.

Coaxial heat exchangers can be readily shaped without distortion into configurations suited to formation of space-saving sizes and shapes.

Coaxial heat exchanger unique heat transfer surfaces offer high performance in condensers, evaporators, chillers, desuperheaters, heating/cooling coils and many other heat exchanger applications. When smooth-tube exchangers with equal pressure drop they offer a four-fold improvement in condensation and up to a three-fold improvement in single-phase heat transfer.

Coaxial heat exchanger has surpassed competition in both performance and cost effectiveness.
