Cremation FAQ, What is the average cremation time?
 
1.
What is the average time needed to cremate an average size case?
Answer: The average time depends on the size of the individual, the type of casket and the temperature of the unit. An average time would be less than 2 hours in our N-20 series models and 60 to 90 minutes in the Phoenix series.
 
2.
 What is the time needed for an obese case?
Answer: Obese cases take longer than regular cremations due to the amount of material that is being cremated and with large amounts of fat being present, the unit is operated slower to better control the combustion process. The size of the individual is the main factor, although the gender also has to be taken into consideration. Most of our models operate at an average 100 pounds per hour destruction rate, with a maximum rate of 150lbs. per hour. The size of the body divided by 100lbs/hr, plus heat up time is the best average.
 
3.
 Is there a fluid gathering device that would be needed in an obese cremation?
Answer: No, our company was the first to bring the ‘Hot Hearth System’ to the cremation industry. This system of using the waste afterburning heat to raise the temperature of the hearth to a temperature in excess of 1000 degrees evaporates the fluids on contact. A slight dishing of the hearth also prevents leakage during such times as the hearth is at lower temperatures.
 
4.
 Are cremations after dark possible due to flames being visible?
Answer: Yes, our cremation systems incorporate the largest afterburning area available. This feature ensures that the gases are fully combusted in the chambers prior to exit from the stack, leaving only heat waves and not flames to be visible. Our stack cooling system also prevents the refractory liner from becoming too hot causing a glow after dark.
   
5.
What is the maximum decibel level of the retort during operation and do we need to put the retort in a sound proof room?
  Answer: The decibel level of our systems is around 55. There is no need to place our equipment in a sound proof room. Other manufacturers systems can exceed 96 decibels.
   
6.
What is the maximum temperature next to the retort during a cremation and will the room temperature change?
  Answer: The outside of the retort is governed by code and should not exceed the ambient room temperature by 60 degrees. Cremation retorts use about 2500 cubic feet of air per minute and require an air louver of at least 24” square to be located in the outside wall of the retort room. This air volume typically keeps the room at ambient temperature.
   
7.

 What is the average cool down time of the retort and does the retort need to be cooled to a specific temp before sweeping out the remains?
  Answer: The cool down period between cremation varies, due to the amount of cremation being processed on any given day.  A typical cool down time is about 15 minutes, but this could be as long as 30 minutes if many cremations have been processed. With our rear retrieval system the remains can be removed at almost any temperature as the main door needs only to be opened 6” to 8”and the remains are the pushed to the rear of the chamber for removal through the side door.
