Drycoolers are simple and reliable equipment. Their principle of operation is based on a sensible heat exchange between air and water where: air is drawn in by fans through a finned coil, while water (or a mixture of water and glycol) flows through the tubes that make up the coil and cools when ambient air (colder cooler) laps the surface of the latter. Exchange coils, with a "V" arrangement within the cooler, consisting of copper tubes and aluminum fins. The angle between the coils, the diameter of the tubes, and the thickness and length of the fins, are sized to ensure the best heat exchange performance, for a given fluid and air flow pressure drops.

The PAD-V adiabatic system is the optimal solution for increasing the efficiency of air systems, with capacities from 75 to 1,100 kW. Dry operation during cold periods: ambient air is drawn in and conveyed to the heat exchange coils (where the fluid to be cooled passes through): no water in the circuit, as during standard dry cooler operations. Energy use is also optimized by electronically modulated fan speeds based on temperatures. Adiabatic operation during hotter periods: outside air passes through the humidifier pack to be pre-cooled, before being conveyed to the finned coils and performing its cooling function: efficiency is increased. This also makes it possible to work at lower ambient temperatures.

RAW/E liquid coolers (water, water/antifreeze) operate through a closed circuit, consisting of a finned coil crossed in countercurrent by ambient air. Due to the sizing of the coil, it is possible to achieve process fluid temperatures close to the temperature of the intake air. They are industrial chillers designed for fluids between 0°C up to 70°C, with external temperatures between -10°C and +50°C: cooling powers available as standard from 64 kWf up to 782 kWf, considering a 10°C difference between ambient air and supply water. “RAW” series chillers are environmentally friendly machines: the fluids used in the cooling process are simply water/antifreeze (fluid to be cooled) and ambient air (cooling fluid). In addition, the use of high quality materials allows the achievement of high efficiency values (ratio of kWf rendered in cooling to kW absorbed in power consumption).

To get the maximum performance with minimum energy and management consumption, it is important that your cooler is always maintained at maximum efficiency. Checking the general condition of the main parts (in the case of an evaporative cooling tower: fill pack, motor fan unit, distribution, etc.), allows to maintain the functionality over time.

Dry coolers are simple and reliable equipment. Their operating principle is based on a sensible heat exchange between air and water where: air is drawn in by fans through a finned coil, while water (or a mixture of water and glycol) flows through the tubes that make up the coil and cools when the (cooler) ambient air laps the surface of the latter. Fins are used to increase the overall heat exchange surface area so that the equipment can be as compact and efficient as possible.

Suitable for both industrial and HVAC fields of application. The adiabatic cooler, sometimes called adiabatic dry cooler or dry cooler with adiabatic pre-coolers, is designed to work with both air and water, with particular attention to efficiency. The external air is used to cool the liquid during dry operation and it is pre-cooled only in hot periods with wetting cycles of about 15 seconds during adiabatic operation (“adiabatic pre-cooling”).

The secret of this system is the combination of the refrigeration section and the free-cooling section depending on the time of day and year: the first mode allowed by these liquid chillers takes advantage of the normal operation of a refrigeration circuit, the second allows cold outside air to be directly conveyed to the fluid to be cooled: maximum efficiency, minimum energy use due to the clear separation between the two sections.

Liquid chillers for low temperatures, also in outdoor environments The RW CW series of process fluid coolers (water, water/antifreeze) are water-cooled and operate with environmentally friendly gas compression. They allow cooled liquid temperatures between -8°C and +20°C. In standard design, ambient temperatures of up to +40°C are permissible, but in the “RW ax/HTA” version even higher ambient temperatures can be achieved. IP54 degree of protection as standard, allowing outdoor installation without a protective roof.

ERW ax systems for industrial refrigeration of process fluids (water, water and glycol) are air-cooled units, using EC (Electronic Control) axial fans. This range includes a series of models with cooling capacities from 2.1 kWf up to 595 kWf. Three different versions are provided for different outlet fluid temperature ranges, agreed with the customer during the design phase. The entire range uses refrigerant with GWP 631.

Low outlet fluid temperatures (water or water and glycol, down to -8°C) characterize RW ax LT liquid chillers: air condensation ensures that they use are electrical energy, and not water, for their operation: a resource that is then optimized by the electronically controlled “brushless” type axial fans. Up to +40°C ambient temperature allowed in standard execution.

RW ax systems for industrial refrigeration of process fluids (water, water and glycol) are air-cooled: the only resource used is therefore electrical energy, a decisive advantage in contexts where it is advisable to save water (because of its cost or scarcity). The IP54-grade machine protection (against dust and other agents) facilitates their installation in outdoor environments, which is also possible at temperatures up to +40°C and above, at the customer’s request. RW ax liquid chillers from Frigofluid are suitable for achieving average fluid outlet temperatures (between +1°C and 20°C), with excellent control of the resources used for their operation.
