Multi Connect all-in-one automation system
The ORION-MC is a highly reliable, versatile communication interface between the greenhouse computer and motor-driven greenhouse systems and valves.
Multi Connect (ORION-MC) is an independent all-in-one automation system that controls, monitors and optimizes greenhouse processes. A unique multifunctional system that enables you to control everything concerning screen installations, ventilation, fans, and air handling units. The ORION-MC interface communicates with the IO units via CAN-local and is compatible with all renowned climate computers and motors. Multi Connect offers a lot of room for control options and future expansions.

ORION-GC climate computer
The ORION-GC is an extremely versatile, functional, and user-friendly computer for climate control in horticultural greenhouses.
With a single ORION-GC climate computer you can control up to 8 greenhouses or compartments individually. The computer controls the greenhouse climate based on room temperature, relative humidity, CO2, water temperature and meteorological data. The precise, steady climate control helps keep crops healthy and perform better, while leaving the grower with virtually no worries. Simple installation (plug & play) and very easy to operate using a central computer, laptop or smartphone.

Greenfield irrigation controller
The GreenField irrigation controllers provide control and management over industrial and small to medium size irrigation systems respectively.
The GreenField and GreenField ECO controllers provide control and management over industrial and small to medium size irrigation systems, maximizing the yield and the quality of the harvest while automating irrigation and fertigation processes. These controllers help to boost plants growth and give the exact amount of water and nutrients the plant needs, to reduce costs, waste, environmental impact. Greenfield features a modular design that allows scalability to grower’s exact needs.

GMC(-U) motor control units
Motor control has never been so easy. Our GMC-1, GMC-2 and GMC-3 units allow motor-driven installations in greenhouses to function flawlessly.
Our motor control units can be summarised in three words: reliable, affordable and simple. The units can be operated manually or automatically. The universal and clear design makes opening and closing windows and screens and controlling hoist motors a breeze. That's exactly what growers want from a motor control system.

GP(M)-1 pump (mixing-valve) control units
Reliable control of pumps and mixing valves is indispensable to control the flow of water. Our GP(M) units are highly reliable and user-friendly.
The GP-1 controls a 1-phase or 3-phase pump flawlessly and can be operated either manually or automatically. The same applies to the GPM-1 pump-mixing-valve control unit, which is primarily used in heating networks. This controls both the pump and a 24 or 230 Vac mixing valve. The GP(M) units are characterized by their universal applicability regarding the control of pumps, valves and heating systems.

EPU-16(-MS) power unit
The EPU-16 is a triac controller that allows direct power control of connected fans or lighting. Carefree & optimal control.
For precise and energy-efficient lighting and climate control, it is crucial that fans and lighting are properly controlled. Our EPU-16 power units work as stepless dimmers and provide secure, precise and safe adjustment. All EPU-16 (16 amp) models are controlled by an external 0-10 Vdc signal from the main controller. Manual control is possible via the display, on which the power percentage can be read and set. Our EPU-16 power units are reliable, affordable and easy to use.

HBS tubular motor units
Our HBS tubular motor enclosures have proven themsel-ves as reliable control units for both individual tubular motors as well as tubular motor groups.
To maintain a homogeneous greenhouse climate and even growing conditions, it is of importance that all control instruments work together harmoniously to achieve the desired setpoints. Mutual differences in window positions and screen openings could frustrate this, to name an example. It is therefore crucial that control commands for opening and closing are univocaly transmitted to and executed by the tubular motors used to operate these installations.

Green EC pH transmitter
Green EC pH transmitter transmits EC and pH sensor data to controllers, providing growers with data required for effective irrigation programs.
The EC pH transmitter converts the relevant signals into a 4 – 20 mA output, which is then sent to a Munters or third party controller. The transmitter can be ordered in two different containers: * Plastic box: wall mount unit, single EC pH readings * Metal box: panel mount unit, single or dual EC pH readings Benefits: • Controller’s proven accuracy provides: » Accurate, continual EC data helps increase yields » pH measurement, preventing issues such as nutrient deficiencies or toxicity
