Karlsruhe – In addition to a modular water cooling system for indoor use in industrial applications and a controlled heating system, autoVimation presents the Turtle series of stainless steel enclosures with a Peltier temperature controller for cameras at this year-s VISION exhibition in Stuttgart, Germany. Available in two sizes, the Peltier enclosures enable users to operate cameras even at extreme temperatures in outdoor applications. This was accomplished by reducing the size of thermoelectric heating/cooling units, which are already well-established as temperature controllers for switching cabinets. Formerly as large as an A4 sheet of paper, the Peltier units now fit into the palm of a hand. They have been adapted for outdoor use, and can even use solar cells as a voltage source in autonomous installations. The Peltier temperature controller automatically switches between cooling and heating operation, which is especially beneficial in desert areas with high temperature differences between day and night. An integrated control unit allows users to easily program thresholds for heating and cooling operation. The camera temperature is monitored constantly. If it exceeds the permitted range, e.g. in case of a malfunction, 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 fisheye lenses, it provides a cooling power of 45 W and a 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 in length with a maximum cross section of 62 x 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 e.g. for use with thermal imaging cameras. Typical applications for both models are tasks in the solar industry, surveillance technology, and astronomy.
