Opticlimate Pro 3 Series
AirSupplies Holland BV

The OptiClimate Pro 3 Series water-cooled air conditioner is the only true total solution for indoor climate control. It cools, heats, dehumidifies, filters and circulates air.
It was developed independently, resulting in a fully optimised & efficient product that controls the indoor climate perfectly while using as little energy as possible.
The OptiClimate cools the air using water as coolant and heats it by means of ceramic heaters.

Most complete stand alone climate system!

Cooling, heating, dehumidifying, circulating and filtering air with a single appliance

Water cooled, you don’t need external chillers

Fully automatic because of the light sensor; set temperatures and ready to go!

Built-in temperature and water leakage safety switch

Opticlimate/Dimlux Range    
Opticlimate Maxi Controller
The Maxi Controller can adjust the output according to the ambient temperature: the lamps are dimmed automatically when the temperature exceeds a maximum pre-defined level.
Using the DimLux with a Maxi Controller enables you to plug the DimLux directly into a wall socket without needing an intervening relay, time delay unit or time switch – which saves you costs.
A DimLux controlled by a Maxi Controller is the only (digital) ballast that does not need to use an inrush current. Inrush currents of conventional (digital)ballasts vary between 50 and 160 Amp, while newer types of digital ballasts use soft-start technology that limits the inrush current to between 50 and 60 Amp – which is still an appreciable current, especially when multiplied by the number of (digital) ballasts incorporated in the circuit.
 £246.99 MaxiController
Co2 controller (Opticlimate Maxi Controller with Co2 sensor)  £705.99 CO2Controller
Co2 Sensor for Opticlimate Maxi Controller  £465.99 CO2Sensor
Plant Temperature Camera for Opticlimate Maxi Controller
An OptiClimate canopy temperature camera can be connected to the system to monitor evaporation from the crop: an excessive canopy temperature is indicative of problems with the plants’ evaporation capacity (for example, due too little water or excessive light). If the canopy temperature rises to an excessive level then the DimLux ballasts are dimmed or switched off until the temperature falls to an acceptable level: failure to lower an excessive canopy temperature would result in the plants reducing their evaporation capacity by closing the stomata, which would in turn shut down the assimilation of CO2 and photosynthesis – and halt growth. A prolonged shutdown will ultimately result in scorched foliage and cause irreparable damage to the plant’s ‘engine’ (the foliage). The canopy temperature is of greater importance to plants than the ambient temperature!
 £185.00 PlantCamera
Dimlux 600 watt ballast (240 volt with manual dim option)
The DimLux can be used as a standard (digital) ballast in a standard system with a relay and time switch.

However, using the DimLux in combination with the OptiClimate Maxi Controller will do full justice to the DimLux’ maximum performance and many options.

£152.99 Dimlux600Ballast
Temperature Sensor for Dimlux Maxi Controller
A Maxi Controller equipped with all the necessary sensors (other than the CO2 sensor) (canopy temperature, ambient temperature and relative humidity sensors) can be used to calculate the vapour pressure deficit: the vapour pressure deficit is a measure of the plants’ maximum evaporation capacity (the potential water demand)
An optional CO2 sensor can be connected to the Maxi Controller to control the dosage of CO2.
All sensors available for the Maxi Controller are precision sensors with a high sensitivity.
Greenhouse technology is now accessible to smaller horticultural enterprises!

SPC twin controllers

The SPC fan speed controller manufactured by SMSCOM is one of the most advanced fan controllers on the hydroponic market. The unit comes wired and ready to use, simply plug in your extraction fan and/or intake fan and you can set your desired temperature and the minimum and maximum speeds of your fans. An external temperature probe on 6 feet of wire controls the unit.

The Twincontroller requires 5 minutes to scan a room and make an evaluation for the gradual increase or decrease of your fans. In the course of a cycle it will automatically find the exact speed to set your fans at to best maintain the temperature set on the unit. This new technique ensures a more even temperature flow and a steadier operation of your fans. It is also worth noting that the SMSCOM Twin controller requires no wiring up as all fans plug straight in and the unit is easily wall mountable.
