Dry block cooling - Import export

The sheet metal is made of stainless steel 304 and powder coated steel in the color black RAL9011. The aluminum heat exchanger is insulated with XPS and equipped with a stainless steel tap spiral with a diameter of Ø8.5 / 9.5mm and connections of 1/2 "male thread. The cooler is equipped with overcurrent and high pressure protections. A signal lamp and a potential-free contact are provided as a fault indication. The control is done by an electronic controller with display.

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.

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).

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.
