Cremators

Macrotec CrematorsMacrotec cremators are designed and manufactured for low Emissions and high Reliability, achieving industry leading low emissions and product life.

Lowest Emissions: Our Cremators are designed to reduce emissions by controlling the rate of combustion in a three chamber process and by capturing Particulate Matter in a settling chamber, resulting in industry leading low emissions.

Highest Quality: Macrotec is certified to ISO 9001:2008 Quality Management Systems, and strive to achieve the highest quality products and services. Our Incinerators are designed to operate in the most harsh conditions, with few moving parts and minimal maintenance required, making MacroBurn Incinerators extremely reliable.

Filtration to EU standards: Macrotec Cremators with Filtration are designed for the absolute minimal emissions while maintaining reliability and Engineering Simplicity.

What is a Cremator?

Cremators are used for the combustion of dead bodies to form flue gas, ash, mineral fragments, and heat. Cremation is normally part of a funeral or post-funeral rite, as an alternative to complete burial. Cremated remains poses no health risk, and is either buried at cemeteries, interred in memorial sites, or scattered

With many religions having strict rules on cremation, the popularity of cremation differs greatly between communities and countries. Cremation has also been advocated for public health reasons, due to the demising area for cemeteries, and environmental concerns.

What makes MacroBurn Cremators so good?

Refractory & Insulation:

Each Cremator is manufactured using duel layers of Refractory and Insulation Castable, forming a single monolithic structure of extreme strength and durability, with a service temperature of up to 1,500°C, Cold Crushing Strength of 110Mpa, and expected lifetime of over 15 years. Heat loss is extremely low, with a thermal conductivity of only 0.2 W/mK, ensuring high energy efficiency.

PLC Panels:

Our PLC’ provide full automation, leaving zero room for operator error. It adds a large HMI screen that displays the status of all components, and creates the ability for remote monitoring and troubleshooting assistance by Macrotec technicians.

Pre-Heated Combustion Air:

The system is designed to recover heat from waste gasses, increasing Fuel Efficiency and ensuring complete combustion due to more stable high temperatures, with decreased fuel usage resulting in a faster ROI.

Reliability:

Macrotec designs and manufactures equipment with Reliability in mind. We understand that you’re most important requirement is minimum downtime, and thus we strive to ensure our machines require less maintenance, that is easy to perform, with extremely high Reliability of all parts

MacroBurn Cremators utilize a three chamber process, with the coffin being placed in the Primary Chamber where highly combustible components are burnt away. Gasses pass through a Secondary Chamber, with a high degree of turbulence for ideal mixing, completing the burnout and eliminating entrained smoke and other combustible particles. A long residency time of over 2 seconds in the secondary chamber ensures complete combustion. A third chamber is located beneath the primary chamber, where all liquid waste is burned away.

Our Cremators are designed with automatic control of air and combustion rate, which will prevent excessive burning and conversely increase combustion when the burning rate is too low, with temperatures regulated between 850°C and 1,000°C.  For maximum automation, our PLC system can be installed that fully automates all functionality, and allows for remote monitoring and alarms of all parameters.

The high temperature and long retention times ensure extremely low emissions.

Cremators with Filtration

Due to the increasing concern of emissions and the impact people have on the environment, Macrotec has designed Cremators with Filtration to help improve the environment we live in. Our solution provides a way to dispose of waste while negating harmful emissions, complying with South African regulations.

Why do MacroBurn Cremators achieve lower emissions?

CO: Carbon Monoxide is reduced the by controlling the rate of combustion and ensuring complete combustion. This is achieved using a 2 chamber process with temperatures between 850°C and 1,000°C, high turbulence and long retention times.

NOx:  Oxides of Nitrogen are reduces using modern burners and controlling input of air and temperature to ensure low NOx formation. Residue NOx is removed by the gas scrubber.

Heavy Metals and Dioxins: Heavy metals, along with Dioxins and Furans are scrubbed from flue gasses using an adsorbent. A dry scrubber is used, resulting in no water use and no impact on the environment.

Particle Matter: Particle matter is removed using a Ceramic Filtration Plant, which removes over 98% of particle matter.
