11.3 Savings

The installation of closed loop pumping trap systems, or a Posipressure system, will return

condensate back to the boiler house. Often on flooded heat exchangers this condensate is drained

to sewer and therefore lost. It can increase the heat exchangers capacity, and may speed up

production processes. More important are the savings achieved from improved system reliability

and controllability, however these are often difficult to quantify. The safety drain will not improve the

condensate return, but will save the coil from freezing and prevent process time downs and

maintenance labour to repair.

11.4 Investments

Average budgetary cost for the installation of a closed loop pumping trap system on an existing heat

exchanger is 14000 €.

Average budgetary cost for the installation of a Posipressure system on an existing heat exchanger

is 8000 €.

Average budgetary cost for the installation of a Safety Drain on an existing heat exchanger is 1700€.

Included:

- Equipments supply (piping, pumping trap / Posipressure, valves etc. )

- Installation by a mechanical contractor

- Engineering and project management

Payback time for these optimizations depends on the specific situation.
