Coil Selection Software

Design, rating and selection software for the manufacturer of coils/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.

Coil selection software

Computair has a coil selection program that has been designed with the coil manufacturer in mind. It allows the user to configure the system with fundamental design details, heat transfer data and costing information. Coil configurations can be added to, deleted or altered as required.

All Coil types accommodated:

  • Hot water
  • Cold water
  • DX
  • Steam
  • Condenser
  • Run-Around Coil design package

Key features:

Selection and rating
All coils with the excpetion of run-around system can either be Selected, i.e designed to achieve a particular duty, or Rated, i.e. the performance of a given coil.
Wide range of geometries and tube sizes
We have a wide range of geometries and tube sizes allowing the user to configure the system and add different geometries and tube sizes on request.
Black Box / Direct Link Library (DLL) / Web Service creation for 3rd party software
Our coil software provides the facility to develop your own black box / DLL or web service that can be incorporated into 3rd party customer software.
Calculation engine for new refrigerants and microfin tubes
We have completely re-written the internal heat transfer co-efficient calculation for direct expansion and condensing coils. The new refrigerants that we have in the system at present are: R410a, R134a, R22, R407c R1270, R134a, R23, R245fa, R290, R404a, R407a, R407f, R507a, R600a, R717, R744.
New refrigerants can be added on request.
