DOSERAY

BLOWER AIR COOLER

Dehumidifiers-Coolers:
This equipment change atmospheric conditions of the air used in the processes. When performing pneumatic transport in some processes, the air delivered by the blower may reach to 65-70oC, possibly making change in the characteriStics of the raw material to be transported. For this reason, complex equipment cooling or removing moisture of the air are required.

With our air-conditioning systems, we can cover virtually all quantities of air, temperature and dew point ranges.
Our customised devices are primarily used in the process air area for use wherever conventional devices in the field of technical building equipment cannot provide satisfactory solutions. In addition to a wide service range, our air-conditioning units can take into consideration customer-specific factory standards or specific hygiene requirements.

We can already cover a wide range of services with our standardised designs, the DOSERAY-COOLER  process air coolers. The proven and advanced devices offer an ideal price-performance ratio, especially for the pneumatic transportation of bulk materials.

Reliable, Efficient, and Sustainable Cooling Solutions for High-Temperature Environments

In industrial blower systems—particularly Roots-type blowers—the compression of air (adiabatic compression) can cause temperatures to reach extremely high levels. This can lead to the deformation of pipelines, a decline in product quality during pneumatic conveying, and a reduction in the service life of the equipment.

Designed with an advanced engineering approach, our Blower Air Coolers lower the high-temperature air at the blower outlet to safe operating levels, thereby maximizing the efficiency of your facility.

Key Technical Features
Superior Heat Transfer Efficiency: Specially designed finned-tube geometries provide maximum surface area, ensuring rapid and effective heat transfer.
Low Pressure Drop: An optimized internal flow design minimizes resistance to airflow, preventing unnecessary energy consumption by the blower.
Durable Material Construction: Built to withstand demanding operating environments; available in aluminum, galvanized steel, copper, or stainless steel (AISI 304/316) for both tubes and housing.
Compact and Modular Design: Offers flexible installation options, allowing for easy integration into existing facility infrastructure, even in confined spaces.
Long-Lasting and Reliable: Features a corrosion-resistant exterior coating and a robust construction that has been subjected to rigorous high-pressure testing.

What diStinguishes the series process air cooler from other coolers?

TheDOSERAY series use an optimised air cooler, which has a negligible loss of pressure in pneumatic applications. The design is suitable for both atmospheric and pressure-resistant processes. The heat exchanger has an energy-efficient design.
 COOLING TECHNOLOGY

• Due to the adiabatic compression high heat flow rates are to be conveyed and extracted, in particular, when the process air cooler has been arranged on the pressure side, so that the process air is first precooled with the ambient air to save energy before it is conveyed to the main cooler. This precooling releases the main cooler and offers the plant user intereSting cash savings. Our economic precoolers of the DOSERAY series are suitable for this purpose as they operate as cross flow heat exchangers and are equipped with their own ventilation blower thus ensuring efficient precooling of the process air. Of course this ventilation unit can be speed-controlled if this is required in the application to obtain precise temperatures.
