Description
Coil-in-coil jacketed heat exchanger, available in 304 or 316L stainless steel.
A coil-in-coil exchanger runs one coiled tube inside another. Process fluid passes through the inner coil and service fluid through the annulus around it, so heat transfers along the full coiled length in a compact footprint. Coiling the pair rather than running them straight is what makes the surface area practical to fit into a skid or a bench installation.
The material option is the specification decision on this page. 304 is the general-purpose austenitic grade; 316L adds molybdenum for better resistance to chlorides and to some acids, and its low carbon content reduces sensitisation at the welds. Where the exchanger will see chloride-bearing or acidic service, 316L is the grade to be asking about. Both options are listed here under separate part numbers, CIC-1/2-304 and CIC-1/2-316L.
Our supplier data gives the coil-in-coil configuration, the two material options and the part numbers. It does not give the tube diameters, coil length, heat transfer area, design pressure or connection sizes, so we do not publish them. On a heat exchanger those figures determine whether the unit performs the duty at all, so ask us to confirm them in writing before you order.
Frequently asked questions
What material options are available?+
304 and 316L stainless steel, selected by the Material option on this page. The part numbers are CIC-1/2-304 and CIC-1/2-316L.
When should I specify 316L over 304?+
316L contains molybdenum, which improves resistance to chlorides and to some acids, and its lower carbon content reduces sensitisation in the weld zone. For chloride-bearing or acidic service, 316L is the grade to ask about. 304 is the general-purpose choice where those are not a factor.
How does a coil-in-coil exchanger work?+
One coiled tube runs inside another. Process fluid passes through the inner tube and service fluid through the annulus between the two, so heat transfers along the whole coiled length. Coiling the assembly packs that length into a small footprint.
What is the heat transfer area?+
Not published. Our supplier data does not record the heat transfer area, tube diameters or coil length, and we will not estimate them. Ask us and we will obtain the figures before you order.
What are the connection sizes and design pressure?+
Neither is stated in the data we hold for this part. Both are decisive for integrating an exchanger into an existing loop, so confirm them with us first.
Is it supplied with insulation or mounting hardware?+
Our source data does not list any accessories with this part, and we do not assume any are included.
