The client

A Global Life Sciences innovator specializing in sustainable, bio-based protective compounds looking to leverage ancient evolutionary mechanisms of photosynthetic microorganisms.

Business needs

The client aimed to scale from shallow, sunlight-dependent cultivation to high-density mass production within 5,000L photobioreactors by replacing inefficient external lighting with a specialized, industrial-scale internal solution powered by precise, high-intensity radiation.

The challenge

01

Environmental Resilience — Engineering "water-sealed" modules capable of continuous operation while fully submerged in 5,000L bioactive environment.
02

Spectral Precision — Delivering three distinct, mission-critical light ranges with laboratory-grade accuracy to trigger specific metabolic pathways.
03

Thermal Management — Dissipating heat generated by high-power LED arrays within a sealed PMMA enclosure to prevent culture overheating and LED degradation.
04

UV Light Transmittance — Finding a way to ensure high light transparency at the UV edge without using traditional borosilicate glass.

Our solution

Multi-Spectral Induction

Deployment of three specialized module types with wavelengths close to UV to allow granular control over biomass growth.
Advanced Encapsulation Technology

Design of custom-machined PMMA tubes with industrial-grade seals and 3D-printed structural components.
Active Internal Cooling

Integrated high-efficiency fan modules within the sealed tubes to manage thermal loads and ensure stable output.
High-Durability UV Optics

Utilizing specialized UV-transparent PMMA instead of fragile borosilicate glass to ensure maximum light transmission.
