Frequently Asked Questions
Yes. Upon notification from the customer that the installation is complete, a Keller technician will travel to the facility to place the unit in operation. Our technician will spend up to three days at the site curing the refractory lining of the cremator, starting up the unit, adjusting air and gas settings and proving all systems. To complete the start-up the technician will perform a cremation and train crematory personnel in the simple operation. It is important that a cremation be available for training at start up.
We warrant our equipment to be free of defects in workmanship for two years and our staff is available around the clock to provide technical assistance and operating support. The Operating & Maintenance Manual describes the function of all components and is invaluable for troubleshooting. We stock a complete line of replacement parts and major components and our Service Department is available for service and repairs on all makes of cremation equipment.
Standard to the KMH-1100 line of cremators is a proven and tested automatic operating system with color touch screen control. Load the body and container in the primary chamber, set the timer and press the Start button to begin the cycle. The system is programmed to begin a 45-second purge cycle before igniting the secondary chamber burner to start the preheat cycle. Once the proper temperature is reached in the pollution control chamber, the primary burner is ignited to begin the cremation cycle. Upon completion of the cremation the system advances to the cool down cycle at which time the burners shut down and clean out of the cremated remains can be made.
Complete combustion is achieved in the KMH-1100 line’s temperature-controlled large secondary chamber. Greater than 99% of volatilized carbon created in the combustion process is converted to carbon dioxide. In addition, an Opacity Sensor is located at the base of the stack to monitor the clarity of the exhaust gases. Once the exhaust gases reach 20% opacity, the PLC automatically shuts down the primary burner and adjusts combustion air supply to slow the combustion rate and prevent visible emissions from exiting the stack.
