Hybrid closed-cooling tower

Hybrid closed-cooling tower

This flow regulation is a market exclusivity. As such, air de-saturation through heating on exiting the tower, and the air humidifying reduction on the packing ensures full plume suppression. In addition to plume suppression, this system reduces water consumption up to 80% and is an additional obstacle to drift.
This technology proposed by Jacir, has been deeply researched in partnership with the CETIAT for over 40 years, and has offered the opportunity to file innovating patents. The hybrid closed-circuit towers are perfectly adapted for operating without glycol in winter. Their design makes access and cleaning very easy and ensures performance lasting.

Process (primary) Side:
The water to be cooled enters into the integrated plate heat exchanger and exits once cooled. Primary (user) circuit is closed and is not in contact with the air.
Cooling tower side (evaporation):
Water is sucked up by a pump, circulates through the plate heat exchanger filtered by a strainer and a FRC centrifugal filter, and enters into the non-freezing plume suppression coil – JACIR patent.
Then, via a power-activated valve, water goes either to the water spraying system to be distributed over the exchange surface, or directly to the basin if the ambient conditions are cold enough for a dry cooling.
The water cooled thanks to the forced draft fan, falls into the bottom of the closed circuit hybrid cooling tower sloped basin.
This technology does not require glycol to avoid exchanger freezing risk. Designed for an easy cleaning or descaling of all the cooling tower components by a very simple operation maintenance.
