Automatic machine for ventilation of greenhouses, +12, +23 ° C, with a closer, universal opening, thermal drive

Thermal drive is designed to ventilate the greenhouses, it automatically adjusts the temperature. Accordingly, when the temperature on the street is reduced - the thermal drive closes the windows and doors.

• Thermal drive has a steel hydraulic cylinder that withstands the pressure on the stem up to 200 kg. This provides high strength of the product, resistance to wind gusts or to a random attempt to close the door manually.
• The opening of the opener implemented the opening of the opening at a temperature that is optimal for most greenhouse crops.
• There is everything in the kit. It is necessary for installation both on the raised window and on the swing window, frame or on a regular door.

the work of the device is based on crystallization of cyclohexanol during melting (crystallization). At temperatures above 23 ° C, the melting liquid increases the volume of the chamber, pushing the stem, opens a window or door. At temperatures below plus 23 ° C, the crystallizing liquid reduces the occupied volume of the chamber, allowing the rod to move to the working chamber, closing the window or door.

Automat for ventilation is designed to work at temperatures from -30 to +50 ° C.

The opening temperature of + 12–15 ° C.

The closing temperature of + 23 ° C.

must be made sure that the maximum force for opening doors, does not exceed 5 kg.

• in the upper part of the opening designed to open, find a place to fix the bracket in order to ensure the movement of the rod of the device to a distance of up to 10 cm..
• Thermal drive should be placed from the side opposite to the opening of the opening.
• secure the bracket of the closing spring on the frame or wall, providing a distance of 16 cm between the centers of the support of the closing spring when opening the door or the oral.
• Fix the locks on the thermal drive and on the closing spring.
• Thermal drive and a return spring for draining condensate is better to place with a chrome rod “Below”. and the closing springs on the brackets.
• If necessary, to remove the latch from the support, it is necessary to raise the locking spring on a plastic latch by 2-3 mm. Inside the greenhouse, it does not take into account the external temperature on the street, which can cause periodic opening (closing) of the thermal drive. The maximum thermal drive (between the supports) is 44 cm.

This model is equipped with a door bracket and gas spring-leader, which allow you to install a thermal drive on the door or door window window.
