Xanthella’s Phycophot™ PBR range is designed to be a universal reactor system, suitable for growing almost any type of microalgae and at any scale while using the same core components. This makes the range very flexible in its application and gives the customer a system that can grow with their needs.
At the heart of all of the systems in the range is our proprietary environmental control system. The Zeus II controller™ is extremely flexible and offers users the ability to optimise, monitor and control the environmental conditions within the PBR for whatever algal strain. As well as RS 232 communications, Wi-Fi is built in so that the unit can be controlled and monitored remotely with a computer connection.
This PBR is a 15 cm (h) x 10 cm (w) x 10 cm (l) Perspex box with a fitted lid and is very easy to set-up and operate. Ports in the lid allow a range of sensor and control functions to be undertaken depending on the user’s requirements. The standard lid includes ports for gas inlet, gas outlet, sampling, temperature and a spare port that can be used for additional functions (such as for pH or light sensors). Magnetic catches make it easy to assemble and disassemble the PBR.
The microPharos™ is lit by two, external LED tiles that are placed on either side of the box, giving an effective light path of 5 cm. The light tiles come with an inbuilt fan to keep them cool when using high light intensities. The standard light tiles are supplied with white LEDs. Other user defined wavelengths and multiple wavelength tiles can be supplied upon request.
Temperature is controlled by a Peltier device driven by the Zeus II Controller ™ unit which uses the thermocouple mounted inside the PBR.
Multiple microPharos™ PBRs can be driven from a single Zeus II Controller™. This PBR is for bench scale research and for teaching purposes and enables researchers to conduct experiments that use a higher number of replicates than would not be possible with rival systems because of cost. Furthermore, the microPharos™ PBR can also be used as a start-up inoculum for larger algal cultivation.
Currently under development and validation is our Pandora PBR™ system designed for pilot scale and industrial scale production. This family of industrial PBRs will be available in a variety of sizes ranging from 100 L to 1000 L. This PBR uses the same Zeus II controller™ and the same LEDs as the smaller ranges, making the scale-up easier.
In addition to the PBR designs themselves, Xanthella offers a range of consumables, spare parts and accessories to complement the PBRs.
