OPTIMA CLIMATE CONTROL SYSTEM
No more air extraction!
A climate control system is essential if you want to run a completely detached closed loop grow room at optimum temperatures, free grin negative external factors (coldness, pests, etc.) and perfectly set up for introducing growth boosting levels of CO2. Likewise, you will also find that these systems are very effective at managing environmental conditions inside grow tents – so plenty of people can enjoy the benefits ! For larger rooms the Optima Pro system is the right way to go!
What are ‘split’ climate control units?
The split type climate control system consists of two main parts – a compressor that treats hot air from the growing space (typically located outside of the growing space) and an indoor unit that treats the air inside the growing space.
Key benefits of Bergdorf climate control units
• Bergdorf is the only brand of climate control available in the UK that doesn’t require a trained engineer for installation
• Unlike the other climate control units on the market, Bergdorf Optima and Growmaster Systems have a whisper quiet function and are designed specifically for grow rooms.
• Uniquely, each one of the Bergdorf climate control units will only draw the power needed for cooling. The 12,000 BTU has a maximum draw of 1000W, but once the room has reached the target temperature it then starts using less of the compressors capacity and reduces power consumption by up to 75% (drawing as little as 250W). The maximum current drawn seen so far from the 21000 BTU Bergdorf Optima at GroWell Wembely is 690W, with the average sitting between 390W and 495W.
• It is always better to over-spec the climate control unit because a more powerful unit takes less time and less energy to achieve the desired temperature settings.
Selecting the required size of climate control unit
To identify the suitable model of climate control unit for your grow room, you need to work out the cooling capabilities (measured in British Thermal Units – BTU’s) required to comfortably manage the anticipated levels of heat. This calculation is largely influenced by the power and number of lighting systems being used, so it makes sense to cross-reference BTU’s with total comined wattage of lamps. But consideration has to be given o other heat sources also, i.e. Ballasts, CO2 burners, Fan motors ect. Fundamental to everything, however, is the insulation and physical dimensions of the space.
Where possible we suggest selecting a 21000 BTU Bergdorf Optima for a 4-6 X 600W lights and a 36000 BTU Bergdorf Optima for 8-10 X 600W lights. Anything bigger in terms of a lighting set up and you should spec two or more climate control units for the room to enable efficient cooling. As mentioned previously, the Optima Pro is for the Big Boys!
|Climate Control Model||Special Features||BTU’s|
|Standard Unit||12,000 BTU|
|GrowMaster Unit||Silent + CO2||12,000 BTU|
|Optima Unit||V Silent + CO2 + Day & Night Settings + UV-C Sterilisers||12,000 BTU|
We recommend the last option – it has more features and it takes less time to achieve the desired results, which helps to save energy and cut costs – but also allows for ballasts etc.
Choice of climate control units
There are 3 different models of Bergdorf climate control systems. The standard unit is a great entry level model, whilst the GrowMaster and Optima offer more advanced features such as CO2 dispersion, ultra quiet models of operation, as well as germicidal sterilisation.
Purchasing a deguidifier alongside a Bergdorf Standard or GrowMaster Climate Control System will typically be necessary because the level of humidity tends to rise during the times of day when a unit is programmed to switch off. On the other hand, the Bergdorf Climate Control Systems have specific night and day settings and so a humidifier is essential.
Each of the Optima, GrowMaster, and Standard Split Climate Control Systems from Bergdorf consist of an indoor unit and an pout door unit.
The indoor unit should always go inside the room or tent.
The outdoor unit can be installed in several different ways:
1) On an external wall or a covered balcony
This is the traditional method used for Climate Control systems.
2) In a nearby, well ventilated spare room, hallway or bathroom.
Multiple outdoor units can be placed in here for multiple grow rooms
To accommodate multiple units in option 2, ONE of the following steps is required to deal with any of the hot air produced:
A) Open a window
B) Set up an RVK extractor fan
C) Use one large complete air con system to cool all of the outdoor units in the room, with only the large outdoor unit actually being mounted outside
D) A separate ‘Cowling’ is available (takes 10” RVK) to remove any warm air.
Completing your set up
If you decide to run with minor negative pressure in your climate-controlled tent/room,
We recommend the following extraction kits:
Tent/Room up to 2.4m x 1.2m = RVK150A1 extraction kit
Tent/Room between 2m x 2m and 3m x 3m = RVK150L1 extraction kit
Tent/Room between 3m x 3m and 5m x 5m = RVK200A1 extraction kit
Tent/Room of 5m x 5m and above = RVK250 to RVK315 extraction kit
To increase airflow during the latter stages of fruiting/flowering, we also recommend equipping yourself with a fan speed controller. CO2 REQUIREMENTS:
Some customers are running Split Climate Control units with Exhale CO2 Bags and getting good results, however the most effective method is to use controlled and dosed CO2 enrichments with a Hotbox Growth Gas Generator and a Dimlux C02 Controller. See below for sizing guide.
|Growth Gas Gen||Room Size||Official Greenhouse 1000ppm|
|0.75kw||2m x 2m x 2.5m||16.5m²|
|2.5kw||4,5m x4.5m x 2m||55m²|
|4kw||6m x 6m x 2.5m||90m²|
|11.5kw||10m x 10m x 2.5m||250m²|
INSULATION: CAN BE CRITICAL !
Without adequate insulation a climate control system will end up wasting energy trying to manage the surrounding environment and/or draw air through the walls, floor and ceiling. A few sheets of kingspan or some cheap rolls of insulation from a DIY store should solve this problem.
If at any point you encounter an issue, do not understand the instillation process, call the technical support phone line for advice rather than risk making a costly mistake.
It is best to over spec the units where possible as this will give you greater tolerance for any unforeseen variables that may affect your grow room i.e. south facing room, heating from rooms below/above or poor insulation, large CO2 requirements meaning longer CO2 burn times.
When you spec larger sized rooms with many lights a better option is to spec two or more climate control units.
A good mix of air within the grow room is imperative and should be achievable with multiple oscillating pedestal or oscillation desk fans dotted about.
The Spigot ports of the Optima Indoor unit can be used to deliver the cool air to multiple areas of the room if required, or hot spots are identified.
