Connection side
Air direction
CODE CLARIFICATION
Codes debunked
Why are the codes on coils so intricate?
Good question – all our heat exchangers feature code combinations that explain exactly how your product is designed.
How is this a benefit for me as a customer?
The codes provide a clear and detailed specification of the design. If you have questions later on, we have all the information you need.
What information is necessary to run a calculation?
For us (or you, yourself, using our calculation program) to run a calculation, we need information about:
1. Connection dimensions
In accordance with your wishes.
2. Air side
• Air flow
• Incoming air temperature
• Outgoing air temperature or heating effect
3. Fluid side
• Type of fluid
• Incoming fluid temperature
• Outgoing fluid temperature or fluid flow
Example of code
Example of a code for a type HW heating coil:
TYPE HW – G A – 1400 – 1000 – 3 – 20 – 12 – X – R6 – AB – AB
TYPE HW – HW heating coil
G – Guide connection
A – Type A = Open ends
1400 – 1400 mm = connection dimension, duct width, where the connection dimension is adapted to match the desired duct dimension
1000 – 1000 mm = connection dimension, height, [4]where the connection dimension is adapted to match the desired duct dimension
3 – Number of rows of tubes
20 – Fin division x 10 mm
12 – Number of circuits
X – Connection side
R6 – Tube geometry
AB – Material specification
