The Green House Application
This application combines an irrigation system and up to
4 climate control systems in the same controller.

Green house Climate Control
The system includes a large diversified and
flexible software package that can be fitted to
the use of almost any farmer without any special
modifications. |

Climate
System Sensors
- Internal Sensors in the
greenhouse includes: temperature, humidity, CO2 and
more.
- External Sensors includes:
wind velocity and direction, radiation, rain meter,
external temperature and humidity and more.
- The normal temperature,
humidity and radiation are carried out by a central
program of requirements according to the day
segmentation. The day (24 hours) can be divided into
up to 8 segments each having required temperature,
humidity and radiation. The control is carried out
(according to the element setup) to maintain the
required condition throughout the day.
On the basis of the above sensors the system
operates the greenhouse components.
Up to 4
greenhouses climate controlled systems can be setup
each containing
Windows (Curtains) (up to 10
- including roof windows): Each of the windows can
open up in 10 stages according to temperature,
humidity, wind, rain, logic conditions and processes
such as CO2 and spraying.
Fans (up to 4)
Refers to the fans installed on the side wall of the
greenhouse and exhaust the air outside the green
house letting fresh air into the green house from
the opposite wall. Up to 4 groups of fans can be
controlled per greenhouse. The fans can be
programmed to work according to the conditions
mentioned for the windows along with cyclic programs
that can change the cycle automatically according to
the temperature. The fans can be dependent on other
process in the same way as the windows.
Thermal Screens (up to 4)
An element in the greenhouse that can be
spread or rolled up according to the level of the
radiation and/or the temperature.
Up to 4 opening stages can be setup.
Cooling System (up to 4)
The cooling system is either wet pads or
fogging systems. It can be operated according to the
temperature, humidity or other conditions. The
process of cooling includes in many cases operation
of other elements such as fans in the case of
cooling pads.
Heating System (up to 4)
The methods of heating the greenhouse are
either hot water heating or air heating. The heating
system is normally programmed to maintain a certain
air temperature by starting and stopping the heating
output. When greater accuracy is required or in more
severe conditions a special program of "Circulating
Heating" is available, allowing PID control of the
water temperature, according to the air temperature
and the heating conductivity data of the greenhouse.
Heating can be dependant on humidity and other
conditions.
CO2 Enrichment (up to 4)
A program controlling the operation of the CO2
valve.
The process of CO2 may include some other elements
such as windows, air circulating etc.
Spraying (up to 4)
This system usually includes a special
device that emits pesticide spray in a certain
location in the greenhouse. The process includes
closing windows and operating the air circulating in
order to ensure that the pesticide reaches all
points of the greenhouse.
Air Circulating (up to 6)
Refers to fans installed inside the
greenhouse that cause air circulation inside the
greenhouse. The programs of these elements include
cyclic operation according to temperature, humidity
and processes such as spraying, CO2 and many others.
This same element can be used also for lighting and
others.

Green House
Irrigation System
The system is composed
of one irrigation head
in which a fertilizer
center performs
sophisticated fertilizer
injection of up to 8
different fertilizers
whilst carrying out the
essential control of
conductivity and acidity
of the irrigation water.

Galcon produces three type
of machines suited to this
application:
