Hood System

Hood System

Preventive Fire is fully certified to install, service, recharge, and repair all types of restaurant hood systems.

We also provide 24-hour emergency service.

Restaurant Hood Systems

There are 2 different types of Vent Hoods and the question you need to ask is:

Will you be exhausting grease-laden air or non-grease-laden air?

Type I-Grease Hoods

Type I kitchen hoods are used over cooking equipment producing grease-laden overflow and are available in a variety of different styles and configurations.

Vent Hood Styles

Type I Hood Style

When it comes to the style of Type I Vent Hood you will need a wall canopy hood if your cooking equipment is against a wall. You will need a proximity or (back shelf) hood if you have a low ceiling and/or it is to be placed over light to medium cooking equipment like fryers or ranges.  You will see proximity hoods used frequently in quick-service restaurants.

Single-Island Style Canopy Hoods 

If your cooking equipment is located in the open and/or in one row, not against a wall, you will require a single-island hood.  Single-island hoods can be seen from all directions and have four finished-all stainless steel sides available in both V-bank and single-bank filter configurations. Preventive Fire offers a variation of the single-island hood for use over pizza ovens. Contact us for more specific information.

Double-Island Style Canopy Hoods

If your cooking equipment is in two back-to-back rows and not against a wall, you will require a double-island hood.

Proximity Hoods

A proximity hood sits close to the cooking equipment permitting lower exhaust rates and smaller hoods.  These types of hoods are shorter in height and width than a canopy hood.  The term “Proximity” refers to the distance of the hood with respect to the cooking equipment.

Type II Non-Filtered Heat and Fume Hoods

Non-Filtered Heat and Fume Hoods are primarily used for ovens or general ventilation applications to capture heat and water vapor, creating a more comfortable environment for the kitchen cooking and cleaning personnel.

Type II Condensate Hoods

These types of hoods are constructed with a gutter and drain and are available in three styles:  The No Baffles, the Single Baffle, and the Double-BaffleContact Preventive Fire to see which one is right for your kitchen environment.

Restaurant Fire Suppression 

The best way to protect against a fire in a commercial kitchen is to have a fire protection system installed in the exhaust hood.  Preventive Fire offers a variety of factory pre-piped fire protection systems by the two leading manufacturers, Amerex® and Ansul®

Appliance Specific Overview and System Features

Appliance-specific fire suppression is a wet chemical system to be used when the equipment placement is known and you expect hardly any if any, changes.

Preventive Fire uses the Amerex® KP or Ansul®R-102™ systems when appliance-specific fire suppression is specified.

Amerex KP

  • Wet chemical
  • UL Listed
  • Pre-pressurized tanks
  • Up to 110 flow points
  • Fusible link or pneumatic tubing detection

Ansul R-102

  • Wet chemical
  • UL Listed
  • Up to 88 flow points
  • Fusible link detection

Preventive Fire offers Amerex Zone Defense and Ansul R-102 Overlapping coverage fire suppression systems. These full flood/overlapping restaurant fire suppression systems were developed to resolve the problem of how to protect a kitchen where appliances are frequently moved around.  Overlapping coverage systems are also cost-effective when more than average protection is needed.

Amerex Zone Defense 

  • Wet chemical
  • UL Listed
  • Flexibility through non-dedicated nozzles
  • Flexibility is in the zone of protection where overlapping spray from multiple nozzles creates an area that is totally flooded by a wet chemical agent
  • Nozzles have placed a maximum of 20 inches apart
  • Pneumatic tubing detection

Ansul R-102 Overlapping 

  • Wet chemical
  • UL Listed
  • Flexibility through non-dedicated nozzles
  • Provides a virtual zone of protection where appliances of various types and sizes are protected by an overlapping wet chemical spray and fusible link detection
  • Nozzles have placed a maximum of 25 1/2 inches apart

Dual-Agent Fire Suppression

Preventive Fire uses the Ansul® PIRANHA® fire suppression system when dual-agent is specified and/or when there is a high chance of a fire hazard, such as with doughnut fryers, solid fuel BBQ’s or smokers.

The Ansul PIRANHA provides a double strike against fire by first attacking it using the rapid flame knockdown and securing capabilities of the PRX™ Liquid Fire Suppressant. Then within a couple of minutes, the cooling effects of water cool the cooking media below the re-flash temperature. The water also replenishes the foam blanket so that it can continue to act as a suppressant.

Ansul PIRANHA

  • Dual-agent
  • UL Listed
  • Only agent-plus-water fire suppression hybrid system on the market

Commercial Exhaust System Requirements

  • The most recent International Mechanical Code (IMC)

The Advantages of Using Preventive Fire to Install

The advantage of using Preventive Fire to factory install a fire suppression system is that pre-piped systems require less installation time, include an application for permits and performing puff testing, and are much more professional looking and aesthetically pleasing.  Also, you do not have to use any holes or pipes.

Preventive Fire is fully certified to install, service, recharge, and repair ALL types of restaurant hood systems.

We also provide 24-hour emergency service.

Types of Fire Extinguisher Products and their Uses:

Class A :

Extinguishers are for ordinary combustible materials such as paper, wood, cardboard, and most plastics.

Class B :

Fires involving flammable or combustible liquids such as gasoline, kerosene, grease, and oil. The numerical rating for class B extinguishers indicates the approximate number of square feet of fire it can extinguish.

Class C :

Fires involve electrical equipment, such as appliances, wiring, circuit breakers, and outlets. Never use water to extinguish class C fires – the risk of electrical shock is far too great! Class C extinguishers do not have a numerical rating. The C classification means the extinguishing agent is non-conductive.

Class D :

Fire extinguishers are commonly found in a Machine Shop. They are for fires that involve combustible metals, such as magnesium, titanium, potassium, and sodium. These types of extinguishers also have no numerical rating, nor are they given a multi-purpose rating – they are designed for class D fires only.

Class E :

Extinguishers are for ordinary combustible materials such as paper, wood, cardboard, and most plastics.
