Automatic greenhouse ventilation

A temperature-responsive window opener is designed to open and close a greenhouse window in response to temperature. Its listed opening temperature range is 17–25 °C, and its maximum opening travel is 30–48 cm. The supplied information does not detail fitting requirements, so check that the opener suits your window and setup before choosing.

Key details

  1. Temperature-triggered operation: The listed opening temperature range is 17–25 °C, giving you a clear figure to compare with your greenhouse ventilation needs.
  2. Specified opening travel: Opening travel is listed as 30–48 cm. Use this measurement when checking the movement needed for your window.
  3. Listed lifting capacity: The stated lifting capacity is 15–30 kg. This is separate from the listed maximum window weight of 60 kg.
  4. Closing force: A closing force of 2 kg is specified. Consider this alongside the window’s weight and the opener’s other listed limits.
  5. Product size listing: The product size is listed as 62 cm. The supplied information does not identify which dimension this figure represents, so compare it carefully with your available fitting space.
