Chromasun Micro-Concentrator

Chromasun Background Chromasun s founders designed and installed the Linear Fresnel Solar Array at Liddell Power Station in the Hunter Valley. This array still stands as Australia s largest solar thermal installation PAGE 2

Fresnel Reflector Optic PAGE 3

Chromasun Micro-Concentrator The MCT is fixed on a rooftop however it has an array of mirrors within the unit that rotate and track the sun to provide 25X sun concentration onto two parallel pipes inside. The result is an industrial grade solar product that is able to efficiently generate steam up to 200ºC, PAGE 4

Micro-Concentrator (MCT) PAGE 6

MCT Tracking Closed loop tracking Autonomous Plug-and-play No need for any optical alignment Integrated output temperature sensing Solar field can be turned off (no stagnation issues) PAGE 7

Chromasun MCT Installation Simple! MCT is self-supporting and has an integrated rack. PAGE 8

Chromasun MCT Installation Simple! The MCT product is a modular plug-and-play concentrator. Installation and execution of the solar array without the complexities that come with other concentrator systems. PAGE 9

MCT vs Evacuated Tubes MCT Non-Evacuated Receiver for 20 year lifetime Stainless-steel boiler tube as receiver. Rated >100bar Evacuated Tube Vacuum Not high pressure rated Capacity to throttle array and stow at any stage. Hail/snow resistant Array cannot be turned off. Safeguarding against stagnation required Limited hail resistance PAGE 19

MCT vs Evacuated Tubes MCT More efficient at higher temperatures/ low DNI Direct Steam Generation capability Evacuated Tube Increased emissivity HX required Able to be integrated with two-stage absorption chillers. Less roof, less water. Limited to single-effect applications PAGE 20
