Options
- Utility Cabinet - ETL Listed for integral side mount on the K-Tech ventilation hood, fabricated of same material as hood. The cabinet can house a factory pre-piped UL Listed fire suppression system* and ETL Listed, pre-wired electrical controls with light switches, lighted fan control switches and internal factory wiring and components (starters, relays, etc.) to reduce field wiring requirements, or the ETL Listed Energy Management System with ETL electrical controls. ETL tests confirm temperatures do not exceed 120°F inside the cabinet during fire condition. (120°F is the maximum allowed storage temperature for the UL Listed fire suppression system and the ETL Listed Industrial control panel. (*Dimensional restrictions may apply)
- Back Supply Plenum - Provides make-up air for the kitchen, discharged below cooking equipment. Welded with stainless steel on exposed surfaces. Unexposed surfaces made of aluminized metal. Shipped separately, requiring field connection. Insulated to prevent condensation. Perforated diffuser plates for even air distribution. Provides required clearance from limited combustibles per NFPA 96 Standards.
- Removable ETL Listed High-Velocity Cartridge Filter - Constructed of stainless steel. Uses centrifugal force to remove grease and other particulates. National Institute of Standards and Technology methodology used by an independent agency to evaluate performance. Tests indicated 95 percent extraction efficiency.
- Captrate® Filter - Removable Combo Filter which combines stainless steel baffle with a unique high tech patented ceramic filter. Provides highest level of grease removal. Meets UL 1046 and NFPA No. 96 requirements.
