Hybrid Cooling Towers

Open Circuit Hybrid Cooling Towers

Centrifugal & Axial fan  Models: SIM / ATIM / KSIM / KHIM

Technologic innovation patented by Jacir ensuring suppression of plume to 2°C outdoor temperature with 80% relative humidity.

All our product ranges are designed to be fitted with plume suppression coils. These towers are referred to as open-circuit hybrid coolers. Their efficiency is ensured by a finned tube coil combined with a modulating valve for adjusting the water spray on the packing. This flow regulation is exclusive to the market. As such, air de-saturation through heating on exiting the tower, and the air humidifying reduction on the packing ensures full plume suppression.

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. Their design makes access and cleaning very easy and ensures performance durability.

Closed Circuit Hybrid Cooling Towers with PHE

Centrifugal and Axial fan   Models: SFIM / CRIM / KSFIM / KHFIM

Standard closed circuit cooling tower ranges have originally been designed to receive the plume abatement coil option; these ranges are then referred to as Closed Circuit Hybrid Cooler range. Their efficiency is ensured by a finned tube coil combined with a valve for adjusting the water spray on the exchange surface (packing). This water flow regulation over the exchange surface is a market exclusivity, JACIR patent.

Therefore, the combination of the air desaturation by air outlet warming up, and the reduction of the water spray on the packing, ensures the complete plume suppression. Beyond the plume suppression itself, this system can provide water savings on average of 35%.
The closed circuit hybrid towers are perfectly adapted for operating without glycol in winter. Their design makes access and cleaning very easy and ensures performance durability.

Closed Circuit Hybrid Cooling Towers with Coil

Centrifugal fan     Model: VHK

By fitting a fin cooling package to the VK closed circuit cooler, a dry cooling element is combined with wet cooling and thus achieves a higher dry cooling performance compared with the classical evaporative cooler. This model of the VK with hybrid design is used when the cooling load is to be discharged air-cooled at cool ambient temperatures without having to forego the low re-cooling temperature at high ambient air temperatures.

Features	Options
35% Water Savings on average	Whirl Sintering / 304 SST / 316 SST
Plume Abatement	Sound attenuation
High Efficiency
High Switch point, wet / dry
Very efficient dry mode
Freezing-safe plume abatement coils without glycol
Hygiene certified VDI 2047

 

Hybrid Water Cooler

Centrifugal fan     Model: HK

Hybrid cooling is a combination of wet and dry cooling which results in environment-friendly heat dissipation into the surrounding air. It combines the benefits of wet and dry cooling without the disadvantages.

In hybrid cooling, cooling is achieved by evaporation at high ambient temperatures, by convection and humidification at medium ambient temperatures, and by convection only at low ambient temperatures.

An additional cooling effect can be achieved by humidification or sprinkling of the heat exchanger, which leads to evaporation of the water on the surface of the heat exchanger. Thus it is possible to cool the working fluid to below ambient temperatures, which is reflected in the investment costs.

    

Features	Options
Very long periods of dry operation	Whirl Sintering / 304 SST / 316 SST
No secondary spray operation	Sound attenuation
High Efficiency
High Switch point, wet / dry
Possibility of indoor installation
Very low water consumption

AzteQ can supply and where required, install a range of water treatment & Legionella control solutions, associated with the safe operation of Cooling Towers and Hybrid Coolers.
