Yes, in various countries.
We’re glad to provide service in all countries. Please contact us through the link and one of our representatives will contact you shortly.
According to our research, at least 27 years. All parts are of very high quality, none of them corrosive.
The heat exchanger which receives the hot water, for instance, is made of titanium. Naturally, however, the machine requires maintenance over the years and it might be necessary to replace worn out parts, as in any machine.
With high humidity caused by plants’ inability to absorb all the water given, they “perspire” and release vapor into the air in order to “cool” themselves. Excess vapor in warm conditions, encourages development of plant diseases, especially botrytis, thus the need for dehumidification. Agam Systems circulate 11,000 CMH (388,462CFH), passing through the concentrated brine which dries about 90% of the airborne spores, thereby decreasing diseases and bringing humidity to an acceptable level.
In addition, humidity helps heat transition to the outside, resulting in a greater loss of heat when humidity is high and the walls and ceiling of the greenhouse are wet.
If needed. Agam representatives attend the first installation in every country, to supervise and instruct the installation and future activation of the system.
3 machines in a 20ft container. 6 machines in a 40ft container.
Yes, a very meticulous process.
Agam Greenhouse Energy Systems Ltd. provides full warranty for a ONE-year period from date of installation for all parts of the system, excluding physical damage to the system caused by mishandling or accidental dropping the machine or any of its parts.
In the event of parts failure during the warranty period, Agam will supply the replacement parts and the local distributor will handle the repair and unit tests.
Agam’s liability shall be voided if any changes are made to the System or any of its parts without explicit prior written consent.
Agam is well acquainted with the successful, unique technology. Nevertheless, keeping the energy in a closed structure creates excess humidity, reducing the quality of the crops. One machine in every structure would provide a good solution for both humidity control and significant saving on heating expenses.
Roughly a thousand square meters, depending on the mass and type of plants. Optimal coverage areas are approximately:
For vegetables: 1,000 M² (10,764 Ft²)
For flowers: 1,500 M² (16,146 Ft²)
For cannabis: 850 M² (9,150 Ft²)
We recommend consulting with Agam staff if you are unsure about the amount of units required.
| Yes, and it’s much more cost-effective. However, it’s essential to match the heaters’ capacity to the number of machines. |
| Depending on energy cost in your country and the construction of the greenhouse, independent research shows 35-65% savings compared to other common climate controlling systems, based on warm air blowers, hot water piping or HVAC compressors. |
| Machines placed on a flat surface (i.e. cement) inside the greenhouse along the walls or partitions. The machine must be at plants’ or table/tray level.
The 2 blowers blow air in either one direction or in two opposite directions. The air reaches up to 35 meters (115 ft.). If the rooms are longer, a mid-section blower may be needed. |
| The VLHC size is approximately 2 x 2 meters square (6’6” x 6’6”) and 2.3 meter high (7’6”).
We ask to leave at least 80 centimeters (2’7”) around the machine for maintenance. |
Yes, we have a ‘long model’ of the system which can be placed along the passageway.
In a well-sealed greenhouse, equipped with a good thermal screen, Agam’s system alone can keep the greenhouse ΔT 18°C above ambient temperature. If the greenhouse is well-sealed but doesn’t have a good thermal screen, the system can keep the greenhouse around ΔT 6°C degrees over the ambient temperature.
Yes, there is a connection. The machine is equipped with a humidity sensor, a temperature sensor, and a control unit. The grower sets the control unit with the target humidity / temperature and with maximum humidity and minimum temperature. Once the greenhouse reaches these conditions, the system automatically starts working.
The control box has different programs such as triggering the machine if humidity exceeds a certain percentage or drops below a set temperature. Programs can be set for mixed humidity and temperatures.
| Electricity: 220V 50 Hz (or 110V 60Hz where specified) 2.7 KWH, one phase with a dedicated 25A circuit barker. Water heater: When using water at 82°C (180°F) stable – 55,000 Cal. (approx. 63KWH), capacity of at least 4 CMH, and resistance of 10-meter head of water. |
When using water at 75°C (167°F) stable – 40,000 Cal. (approx. 50KWH), capacity of at least 4 CMH, and resistance of 10-meter head of water.
The hot water is used for separating the brine from plain water, also called “regeneration” (reconditioning) of the brine for continued use. The warmer the water the dryer the air out of the blowers. The VLHC also has the option of generating “extra heating” to maintain the greenhouse at the right temperature in colder climate regions.
| VLHC has the option of increasing the temperature by up to 4°C (7.2°F).
The radiator in the main tower has 3 tiers. The lower 2 are for the brine’s regeneration process. The top level receives hot water, either directly from the heater connected to the system’s Regenerator requiring a water temperature of 82°C (180°F). If there is a heating system, a water temperature of 60°C (140°F) is sufficient. Extra heating is optional and is activated if the greenhouse temperature drops below the desired temperature and regular operation is not enough. |
No. The brine is created from Lithium Chloride (LiCl) and water. It’s a stable solution that will not crystalize, evaporate or lose its strength, if kept clean from external dirt or debris. The brine circulates in a closed circuit, with no reason for human intervention.
No. The design of the machine prevents the brine’s vapor from leaving the tower, the regeneration section or the plumbing.
Good common sense preventive maintenance (according to the machine’s maintenance book), along with the mandatory brine-spill containment basin, prevent leaks during catastrophic disasters.
| It’s a very large tray placed under the machine to safeguard that in the unlikely event of brine spill, it will never reach the greenhouse floor or soil. It collects all the liquids in the machine.
This inexpensive add-on may save thousands of dollars in case of emergency. |
| In general, unlike common AC units, the Agam System creates climate conditions where there’s not much water in the air to begin with, therefore, there is less water to extract from the air. However, since water extraction is a common measuring benchmark, we publish that the system extracts 18 – 25 Liters (4.75 – 6.6 Gallons) of condensed water per hour. |
