Booth number: E3

About us

CAW designs and fabricates industrial high temperature process heating systems, thermal oxidizers / waste incinerators, modern solid fuel firing systems for thermal utilization of wood waste and low quality biomass as well as decentralised power stations using ORC-technology.

The reciprocating grates are versatile, reliable and very tolerant to a broad variety of fuel sizes and physical moisture contents while performing excellent burnout and minimum emissions  in combination with with near-adiabatic combustion chambers specially designed for and adapted to the fuels and their characteristics.

All products are completely customized and designed for maximum efficiency and minimum environmental impact by permanent optimization of the combustion parameters, application of low-NOx firing systems and waste heat recovery systems. CAW's scope ranges from pre-contractual engineering and feasibility studies through single plant components and up to turn-key energy centers. The KONTAKTOMAT-thermal oil heaters are designed, fabricated and tested acc. to all applicable codes and standards.
