Standard Electrical operation - GT35
The Gorter GT35 electrical operation is a solution, which can be fitted on any standard Gorter RHT roof hatch or floor door of the type WA, WAPT and OP. The two powerful electric motors are always fitted as a pair on both sides of the lid.

The Gorter GT35 is a system with two motors and a control unit. The system comes standard with a wireless remote control and a compact control panel. The keypad connected with signal cable can be installed remote from control unit.

Keypad: +/- 70 x 50 x 10 mm
Length of signal/power cable motors: 2 m
The drives and the wiring must be installed by a certified installer
Operation for a hatch with double lids
Depending on the access door type, the weight of the cover and the application, we can install one or more gear rack drives. These drives are available in 24 Vdc or 230 Vac.
Operation and control 230Vac
This is the simplest system with 1 motor. It can be operated with an integrated or surface-mounted switch, not included.
Operation and control 24Vdc
Operation of one or more drives is controlled by a control box with rectifier that is connected to the electricity network.
Depending on the features we will recommend a suitable control box type.
Emergency hatches and doors:
It is of life importance that an emergency door opens after a break down of the electrical system. For those reasons a control box can be provided with a built-in emergency power pack.
The drives and the wiring must be installed by a certified installer.
