How It Works
Why You Should Choose A DENLAR Hood System.
Mechanical Fusible Link Actuation
When exposed to high heat conditions (fire) the fusible links melt, mechanically actuating the system. If there is no power to the area, and a fire manages to start, the system has the ability to actuate and suppress that fire event. Per the manufacturers' instructions, fusible links should be changed a minimum of once per year.
Range Element Disconnect (Gas, Elec. & Dual)
DENLAR hood systems feature hardwire connected range element disconnect options for Gas, Electric or Dual Element devices. These modules work to disable the cooking element in the event of a system actuation (or a maintenance alarm - D1000). The cooking element will not come back on-line until the system in recharged and/or reset. These range element disconnect options are hardwired, takeover devices and cannot be bypassed.
Low PH Wet Chemical Suppressant
DENLAR hood systems utilize the low PH version of a standard commercial-grade wet chemical suppressant. If the system discharges, clean up is as simple as soap and water. Also, this chemical agent will not harm the finish of the appliance or the surrounding countertop. The suppressant tank can be recharged by any fire equipment specialist or new suppressant tanks can be purchased from a DENLAR distributor.

Prior to the introduction of the DENLAR fully integrated, pre-engineered fire suppression range hood system; there were few options available.  An official looking to protect a residential-grade appliance could require a full commercial hood system (often meaning a $20k hood system was installed over a $500 SEARS range) or allow a lesser retro-fit kit to be installed within a basic BROAN style hood.  Neither option was ideal.   The official either became the cause of a major cash expenditure to the facility or was forced to jeopardize public safety by allowing an unbonafied safety system to be used.

When comparing a true commercial hood system with ANSUL to a DENLAR Hood, the value in the value.  The DENLAR D1000 provides all of the protections of the type-1 alternative in a system specifically designed for a residential grade appliance.  A significant argument can be made that the environmental monitoring capabilities of The D1000 create an even higher level of protection, in that it will interact with the cooking environment to lessen over-all fire risk.  All of this in a product that is often 1/3 the price of an otherwise required commercial system.

When comparing residential grade retro-fit kits to a DENLAR Hood, the value is in the overall quality and ease of use.  The DENLAR Designer Series provides a similar level of protection to the retro-fit/residential hood combination, but in a pre-engineered "One Product" system.  By selecting a system that is pre-engineered and factory integrated you are creating a safer environment by removing much of the human element at installation in addition to minimizing tampering that is likely to occur in a conspicuous retro-fit assembly.  The DESIGNER Series fulfills this need and the existing two product standard in a "One Product" system that offers lower materials cost, lower installation costs and a much finer finished aesthetic.
