Tassu provides a retrofit‑ready electric diffusion charging (EDF) module that ionizes exhaust gases from wood stoves, charbroilers, cremators and small bio‑fuel boilers, charging particles so they electrostatically deposit on internal electrodes. The system captures over 90 % of fine and nano‑scale particulate matter, recovers waste heat, and integrates with existing maintenance cycles to help operators meet European emission limits.

Problem
Combustion processes in domestic wood heating, commercial charbroiling, crematoriums, and small bio‑fuel power plants emit fine particles and nanoparticles that penetrate deep into the respiratory system and contribute to ambient air pollution. Existing abatement solutions are bulky, costly, or ineffective at capturing sub‑micron particles, leading to regulatory non‑compliance and health risks.
Solution
Tassu’s Electric Diffusion Charging (EDF) system is a retrofit‑ready module that integrates directly into existing combustion equipment. The unit ionizes the process gas flow, imparting a unipolar charge to airborne particles; charged particles are then electrostatically attracted to oppositely charged metal surfaces within the device. Collected dust settles in an accessible ash box that can be emptied during routine maintenance, while excess heat is recovered for on‑site heating or electricity generation. The EDF module operates at high temperatures and in dry environments, delivering high capture efficiency for particles down to the nanometer scale without requiring major plant modifications. By enhancing the performance of wet scrubbers and other downstream controls, the system helps customers meet tightening emission limits with minimal capital outlay.
Target Audience
Primary customers are operators of residential biomass heating systems, commercial kitchens with charbroiling equipment, crematorium facilities, and small‑scale bio‑fuel power plants seeking cost‑effective particulate abatement and regulatory compliance.
