WinCoil Selection Software

WinCoil provides a rapid and accurate means of selecting expanded surface heat exchangers.

Typically the heat exchangers (or coils) will be constructed from copper primary tubes with aluminium or copper fins attached to them by mechanical bonding. The coils are to be selected by means of fundamental equations working in conjunction with an operator amendable database.
