KARLSRUHE, Germany, Dec. 16, 2012 — The Turtle series of stainless steel enclosures with a Peltier temperature controller for cameras is being launched by autoVimation. Available in two sizes, the Peltier enclosures enable users to operate cameras at extreme temperatures in outdoor applications. This was accomplished by reducing the size of the thermoelectric heating/cooling units. Formerly as large as an A4 sheet of paper, they now fit into the palm of a hand. They can use solar cells as a voltage source in autonomous installations. The Peltier temperature controller automatically switches between cooling and heating operation, which is beneficial in desert areas with high temperature differences between day and night. An integrated control unit allows users to program thresholds for heating and cooling operation. The camera temperature is monitored constantly. If it exceeds the permitted range, the control unit will shut down the camera, protecting it from damage. The Turtle S model has an inside length of 165 mm and is suitable for cameras with lenses measuring up to 120 mm. Equipped with a dome glass front lid for use with fish-eye lenses, it provides cooling power of 45 W and heating power of 70 W. With an inside length of 335 mm, the Turtle L model is suitable for larger camera and lens combinations up to 250 mm long with a maximum cross section of 62 × 62 mm. Providing a switchable cooling power of 30 or 60 W and a heating power of 90 W, it is available with a scratch-proof germanium window for use with thermal imaging cameras. Typical applications for both models are tasks in the solar industry, surveillance technology and astronomy.
