Features Of The N-20SA Human Crematory

CONTROL SYSTEM AND POLLUTION MONITORING - This system constantly monitors the stack gases to prevent visible emissions.  Integrated with the automatic system, this feature enables the unit to make all necessary adjustments automatically.

FRONT CLEAN OUT - A stainless steel remains removal pan, located in the front of the unit, is included to enable the operator to pull the remains to the front of the chamber, then sweep the remains into the clean out chute.

FULLY-AUTOMATIC CONTROL SEQUENCE - Operation is made simple by the fully-automatic control sequence.  A microprocessor temperature controller with a digital readout ensures optimum control while providing the lowest fuel consumption.  Visual verification of each stage is provided on the control panel.  Operator override is achieved by a turn of a switch for semi-manual control.

HOT HEARTH DESIGN - First introduced by B&L, this design allows for wasted afterburning heat to be recycled through the floor, eliminating fluid problems, lowering fuel consumption, and extending the hearth life.

HYDRAULIC LOADING DOOR - Push-button operated, this feature enables the operator to open the door to the desired height from the control panel.  An important safety feature for busy installations, it provides better fuel efficiency and longer refractory life.

LOW NOISE - The secondary combustion blower has been manufactured and installed to allow for low noise operation.

MULTI-CHAMBER AIR CONTROLLED DESIGN - The entire combustion process is completed within the air controlled chambers, allowing for 24 hour operation, eliminating burning in the stack, and providing for greater fuel efficiency over excess air designs.

PAINTED STEEL FRONT - Our high temperature paint is sprayed on, then rolled for a textured finish.  Our classic colors are B&L gray sides and front with a black loading door, but we also offer custom colors to reflect your company.

REFRACTORY - The refractory for our N-20SA is made from 4.50 inch thick, 3,000 degree Farenheit high-duty refractory walls in all chambers.  This is the standard among most major crematories.  The hearth is cast from 3,000 degree Farenheit abrasive resistant material, and the main chamber ceiling is insulating firebrick to provide better fuel efficiency and longevity.

REFRACTORY LINED STACK - A three inch insulating liner is provided as a safety feature.  While gases seldom exceed 1,000 degrees Farenheit, the liner reduces heat penetration under every condition, preventing the possibility of fire.  A ten year warranty is offered on the stack liner.

STARTUP - Startup is made easy, as our units are fully piped, tested, and wired prior to shipment from the factory.  Once the machine has been off-loaded and the stack and utilities hooked up, our factory-trained crematory technicians are available for startup and training service for up to five people.
