pyrotec animal no. 3/2

design
The Pyrotec AP is a modern incinerator designed to burn animal and pathological waste in a clean and environmentally safe manner. Recuperating heat from the combustion process within a multi-pass secondary chamber beneath the crematory hearth makes the Pyrotec AP Hot Hearth Incinerator ideal for the incineration of animals, pathological and high moisture content waste. Suitable for animal crematoria, veterinary centres, research companies, abattoirs, agricultural establishments and hospitals. It is equipped with the necessary sophistication of control, secondary chamber volume, manual or automatic loading options and chimney.

models
AP150, AP200, AP250, AP300, AP400 and AP500.
