Procom Computer Based Greenhouse Control System

 

PASSIVE COOLING/VENTILATION

• Side Vents
• Roof Vents
• Roll Up side Curtains
  • By using the standard outputs in the Procom, any motorized vent system or roll up sidewall system can be operated in up to eight stages of cooling without the need for any external limit switches. Changing position openings can be done in seconds from the from of the panel. All passive outputs feature adjustable time delays, temperature spans and differentials.

     

AIR CIRCULATION

• Horizontal Air Flow Fans
• Jet Fans
  • The Procom features air circulation capabilities that can operate any equipment to turn on or off in relation to a vent stage or cooling outputs.

     

ACTIVE HEATING AND COOLING

• Evaporative Coolers
• Positive Pressure Systems
• Gas Fired Unit Heaters
• Motorized Shutters
• Exhaust Fans
• Pad Pumps
• Radiant Heating
  •  

    The Procom system will operate any active cooling and heating equipment in maintained stages of operation. Up to four temperature settings can be entered for all equipment. Day, Midday, Evening and Night Modes are standard. DIF operations are simple to use. All outputs feature adjustable time delays, temperature spans, and differentials.

     

SPECIAL FUNCTIONS

• Alarms systems
• Irrigation /Mist Watering
• Fog Systems
• Shade Systems
• HID Crop Lighting
• Dehumidification
• Carbon Dioxide Generation
  • The inclusion of these special functions sets the Procom far apart from standard greenhouse control systems. Fog system will be operated based on temperature and humidity levels. Shade Systems will cover when solar level is to high, and also act as an energy curtain when conditions warrant. A full complement of alarm features.

     

HOT WATER HEATING

• Boiler Systems
• Mixing Valve Operations
• Soil Bottom Heating
• Concrete Slab Heating
  • The latest up to date hot water heating systems are standard on the Procom. From slab heat to four way mix valves, the Procom is factory ready for any hot water heating task.

Control panels. Typically plan to locate the control panel(s) near your main distribution panel or sub feed panels . It'll make for a cleaner and more efficient installation. A control panel ??? The panel would include the line voltage contactors and or relays and the low voltage relays which provide power to the equipment. If you wish this can be built on site by your electrician .... or .... ask us to provide a completely preassembled, wired panel for you. We find this generally the best route to go. On larger installations, you may find it best to have a separate control panel per zone ( ie near the sub feed panels ). If you wish a quote on a pre-assembled control panel on the point list make use you include the motor size / voltage / phase and amperage of the devices.

Sensors. Sensors are available in both non aspirated and aspirated forms. You will see the aspirated sensors are more costly. Which to use. Generally in greenhouses that have suitably sized horizontal air flow fans and air movement we see no real advantage to using aspirated sensors. We have had many clients that have downgraded from aspirated to non aspirated and ask them if they see much difference . We find only the growers with bench type crops and roof vent systems will see an appreciable difference and use aspirated sensors.

Programming the unit. Setting up schedules, heating set points, cooling set points, humidification set points etc. is very easy. This is all accomplished via the programming toggle switches. All the programming switches are setup in a consistent method.

Grow link software is a very nice package. The only thing that Grow link provides is the ability for remote control, data acquisition and data storage. Remember the Procom unit is really the control device. Basically the Grow link just communicates with the Procom unit or units. So in terms of control quality the standalone Procom unit will control all by itself. For you smaller growers our best advise is the Grow link software would be a nice future upgrade and should only be considered for those that really need remote control and data acquisition. This in itself can be powerful information for the grower. For an installers point of view the nice feature about the power and flexibility of the Procom unit is if control changes ( ie set points etc. ) need be changed, they can be done right at the Procom unit ( which is usually close in the greenhouse ) without having to run across the complete to the computer.

Single/Zone Multi zone. Even if you are a single zone user the power and flexibility that the Procom unit can provide is of important value for you. You can add additional control sensors and equipment systems as you grow and the basic Prom unit will grow with you. Treat the purchase of your Procom as an investment. Need a few extra stages of heating ? Cooling ? Some irrigation zones ? Carbon Dioxide Generation ? Shade/Energy curtain control ? All can be added without having to dispose of or radically changing your Procom unit. This equates to $$$ savings and ease of operation. When adding equipment it is simply telling the unit which output you are connecting it to, the function of the equipment ( ie heating, cooling etc. ) and the sensor that is providing the control. If you started off with a basic Procom unit and require additional points of control .... just simply add an expansion module when this occasion arises. Procom is a very powerful building block .... note we always add ...... not replace.

Energy Savings. Just being able to provide as many stages of heating, cooling etc. The installation of a Procom unit will greatly reduce your monthly cheque that you write to the utility company. The unit end up paying for itself. Also there is the energy savings from you management side. No more running around tweaking this control device and tweaking this control device. It just makes life easy. Growers should spend all their time tending to their crop, not to their controls and equipment.

• Just simply consider this --- all inputs ( up to eight sensors ) are all grower defined. All outputs (12 standard), (24 with expansion module ) are all grower defined. And can be reprogrammed right on the wall without any additional hardware or software costs. And 24 VAC operation ---- Hmm were else can you find anything that packs this type of punch.

   

  Just remember, the Procom does all of these functions all by itself and if you really wish to explore the maximum flexibility of this system, simply add our Grow Link software to your IBM based PC and you have the power of remote control and data acquisition.

   

  And the beauty is it is completely programmable/expandable and will grow as you grow.
