3 good reasons to opt for the new generation Baltibond hybrid coating

The effect of cycles of concentration on water and chemical consumption

Ice thermal storage products are used to build and store cooling in the form of ice during periods of reduced cooling demand. This way the mechanical refrigeration system needs not to be sized on peak load but on average conditions. Hence a smaller refrigeration system with much lower power requirements and a smaller refrigerant charge can be selected. Ice thermal storage products can either be of the internal or external melt type. For internal melt only glycol solutions can be used as secondary refrigerant. External melt ice storage products can use either direct refrigerant feed or glycol solutions.

LOW ENVIRONMENTALIMPACT PRODUCTS

Critical spare parts kit

The performance of BAC open cooling towers is Eurovent certified.Open cooling towers are a proven and cost-effective method of cooling condenser water loops and industrial processes. In operation, the condenser water (or process water) flows directly over the heat transfer surface of the open cooling tower. As air is introduced into the tower, a fraction of this water is evaporated, cooling the remaining water. Open cooling towers provide evaporative cooling for many types of systems, and the specific application will largely determine which BAC cooling tower is best suited for a project. There are two main configurations of factory assembled open cooling towers: crossflow and counterflow. In crossflow cooling towers, the water flows vertically down the wet deck as the air flows horizontally across it. In counterflow cooling towers, the water flows vertically down the wet deck as the air flows vertically up it.

Open Cooling Towers

Addition of product accessories can improve standard product features e.g. sound attenuation, plume abatement, maintenance, operational safety, corrosion protection. Contact your BAC representative for more information.

Closed Circuit Cooling Towers

Closed circuit cooling towers keep the process fluid clean and contaminant free in a closed loop. This creates two separate fluid circuits: an external circuit, in which spray water circulates over the coil and mixes with the outside air, and an internal circuit, in which the process fluid to be cooled circulates inside the coil. During operation, heat is transferred from the warm fluid in the coil to the spray water, and then to the atmosphere as a portion of the water evaporates.

BAC manufactures two types of closed circuit cooling towers: combined flow and counterflow.

Combined flow closed circuit cooling towers have both a heat exchange coil and wet deck surface for heat transfer; they utilize parallel flow of air and spray water over the coil, and crossflow of air and spray water flow through the wet deck surface.

VXI19 - 2615 kW

VFL70 - 575 kW

FXV-D1425 - 2290 kW

Evaporative CondensersIn an evaporative condenser, refrigerant vapour is condensed in a coil, which is continually wetted on the outside by a recirculating water system. Air is circulated over the coil, causing a small portion of the recirculating water to evaporate. The evaporation removes heat from the vapour in the coil, causing it to condense. Evaporative condensers provide lower condensing temperatures and compressor kilowatts savings up to 30% when compared with air cooled systems. BAC manufactures two types of evaporative condensers: combined flow and counterflow. Combined flow evaporative condensers have both a heat exchange coil and wet deck surface for heat transfer; they utilize parallel flow of air and spray water over the coil, and crossflow of air and spray water flow through the wet deck surface.

Water saving and hybrid products (HXI, HFL) are of the closed circuit type where the heat load to be rejected is transferred from the process fluid to be cooled to the ambient air through a heat exchange coil. The coil serves to isolate the process fluid from the outside air, keeping it clean and contamination free in a closed loop. The hybrid wet/dry products cool the liquid to be cooled by efficiently combining dry sensible air cooling with evaporative cooling. These products include two or more distinctive heat transfer surfaces or sections combined into one product optimising the use of the ambient dry and wet bulb temperature.

Water Saving Condensers

The HXC hybrid condenser offers significant water savings versus traditional water-cooled and evaporative condensers. Thanks to the standard design features the HXC satisfies additional environmental concerns by minimising also energy consumption, refrigerant charge and plume. The TrilliumSeries condensers are dry condensers equipped with an adiabatic pre-cooler section. Before the air is drawn through the high density finned coil however, it is pre-cooled adiabatically as it passes through an evaporative pad where water is evaporated in the air.

Before the air is drawn through the high density finned coil however, it is pre-cooled adiabatically as it passes through an evaporative pad where water is evaporated in the air.

Principle of operation

Warm process fluid (1) enters through a heat exchange coil (2) andgets water sprayed on by the spray system (3) at the top of the coolingtower. At the same time the centrifugal fan (4), located at the bottom ofthe unit, blows ambient air upwards (5) through the tower. Duringoperation, heat is transferred from the internal circuit coil to the water,

and then to the atmosphere as a portion of the water that evaporates.

The cooled down fluid then exits the unit (6). The tower sump (7) orbasin collects the remaining water. The spray water pump(8) recirculates the water up to the water spray system. The warmsaturated air (9) leaves the tower through the drift eliminators (10) ,which remove water droplets from the air.
