Thermocoil designs all its heat exchangers in house, usually in collaboration with the customer/end user and/or Kovco (Pty) Ltd. Our designs and coil selections are based on European standards. Our selection program (developed for us in Germany) is conservative by default giving us an automatic safety margin on performance. Once initial designs and selections are approved, all units are modeled in 3D* from where drawings and data are fed back to the client for further approvals and directly to the factory for CNC fabrication and assembly by our skilled production staff. *The exception to this are AHU type coils, which are drafted on the fly in real time based on selection data by our automated software. This leads to rapid design turnaround time with minimal chance for user error.
