Human Cremators

Human Cremators for Crematoria and Funeral Homes

Macrotec's human cremators are engineered for the clean, smokeless and dignified cremation of human remains, built for municipal crematoria, funeral homes and hospital mortuary services. A two-chamber design holds combustion gases at high temperature throughout the cycle, so operation runs without visible smoke or odour. Designed and manufactured by Macrotec, with over 40 years of experience in high-temperature process equipment.

How It Works

Two-Chamber, Clean Combustion

Remains are placed into the primary chamber, where they are heated and combusted under controlled conditions. Rather than driving the whole process to completion in one step, the primary chamber handles the initial reduction while the resulting gas stream is passed forward for further treatment, keeping the visible output of the process to a minimum.

That gas stream enters the secondary chamber, where additional combustion air and a dedicated burner hold the temperature high enough, for long enough, to combust the remaining organic compounds fully. This is the step that governs whether a cremation runs clean and smokeless or not, which is why the secondary chamber's temperature and residence time are engineered and monitored, not left to chance.

Burner firing and combustion air are controlled automatically throughout the cycle, so the unit holds its operating conditions consistently from the first cremation of the day to the last. What remains at the end of the cycle is calcified bone fragment, not ash, which is why a separate machine, the cremulator, is needed to produce the fine, uniform remains a family receives.

  • Automatic temperature and airflow control
  • Clean, smokeless operation
Applications & Use Cases

Serving Crematoria, Funeral Homes and Municipal Facilities

From municipal and privately operated crematoria to funeral homes managing their own on-site cremation, and hospital settings handling pathological or anatomical remains where local regulation permits.

Municipal & private crematoria

Funeral homes & funeral groups

Hospitals, pathological & anatomical remains (where regulations permit)

Government & municipal authorities

Independent crematorium operators

Regional service providers in underserved areas

Features & Benefits

Engineered for a Dignified, Reliable Service

Clean, smokeless operation

A two-chamber design holds combustion gases at high temperature throughout the cycle, so the process runs without visible smoke or odour, as families and neighbouring communities expect.

A dignified, respectful process

Controlled combustion and consistent operation replace manual guesswork, giving crematoria and funeral homes the calm, repeatable process the service demands.

Runs on what you have on site

Diesel, LPG or natural gas burners mean the unit is specified around your facility's fuel supply, not the other way round.

Efficient, reliable daily operation

Efficient fuel use and refractory built for daily cycles keep running costs down and the facility available when a service is booked.

Built on four decades of furnace engineering

The refractory and burner engineering behind each unit is carried over from Macrotec's broader thermal process equipment manufacture, not adapted from a single-purpose design.

Pairs with our Cremulators

Once cremation is complete, our cremulators process the remains into the fine, uniform ash a facility returns to families, completing the service with the same equipment provider.

Compliance & Certification

Clean Operation, Independently Certified

Our human cremators are engineered to meet the air quality and emission requirements that apply to crematoria in our clients' regions, with the applicable limits confirmed for each project. Our quality, environmental and occupational health and safety management systems are independently certified to ISO 9001, ISO 14001 and ISO 45001.
