A line of direct-air coolers is ready for work cooling electronics in diverse outdoor applications. The Direct Air Cooling System (DACS) is a cost-effective alternative to closed-loop coolers for a wide range of applications says the developer. Using quiet fans, enclosures equipped with a DACS cooling unit draw filtered ambient air into the enclosure to dissipate heat, enhancing the operation of sensitive electronic components.
The system comes in four standard models, from 29 to 56-in. high and with Hydrophobic GORE and MERV 12 filters. DACS units can be customized to suit many applications. Models are available in aluminum, stainless steel, and many paint options to compliment individual enclosures. Additionally, with power input options of 24, 48, 115 and 230V, DACS is built to meet individual application requirements.
For applications prone to moisture exposure, models equipped with Hydrophobic GORE filters use a microporous membrane. The filter is highly permeable to air while simultaneously preventing water and other corrosive particles from infiltrating enclosures. Alternatively, models featuring MERV 12 pleated filters provide a cost-effective cooler with off-the-shelf convenience. Since DACS models have distinct filtration capabilities, users can select the unit best able to accommodate the specific protection needs for their application.
All models are equipped with a controller to adjust fan speed based on temperature. This control provides soft start and precise current limiting at start up, noise reduction, and energy efficiency. The controller also delivers alarm logic so preventative measures can be taken. A composite alarm is provided for high temperature, loss of power, and failure of the temperature sensor.
Additional features include easy-to-replace filters and variable-speed blowers for quiet operation. Constructed to withstand harsh conditions, the system offers operating temperatures from -40 to 55°C, vibration resistance and is UL Type 3R, CE and Telcordia GR-487 capable. This lets the units deliver reliable cooling in diverse outdoor applications such as telecommunications equipment, kiosks and displays.
