CANOPY HOODS TYPE 1 AND 2

Type 1 hood systems are the frontline defenders against the onslaught of grease and smoke produced by high-heat cooking appliances. Designed to capture grease-laden vapors and smoke at the source, these hoods are commonly found above deep fryers, cooktops, charbroilers, and other equipment for preparing greasy foods. 

Type 2 hood systems focus on a different battlefield: heat and moisture. These hoods cater to kitchen equipment like dishwashers, ovens, and pasta cookers, which generate heat and steam during operation. Type 2 hoods contribute to a more comfortable and productive working environment by efficiently removing excess heat and moisture from the air 

Each HVAC system typically uses two plenum boxes: a supply plenum and a return plenum.

A supply plenum works by taking in the new cool or warm air from the heater or air conditioning system and, in turn, distribute it throughout the building using the HVAC’s ductwork.

A return plenum takes in that used air and, using the ductwork, sends it back to the core HVAC system. That air is recycled as a fresh batch later.

Permits are required by law. Before work can begin, contractors must obtain, or “pull,” a permit.

Your city, municipality and/or subdivision may have different restrictions and requirements. But regardless of your location, an HVAC installation requires a permit.

An inspection ensures that the permitted job was done correctly. 

Your permit fees cover the cost of an inspection. If the equipment was installed improperly, you or your contractor may have to pay for additional inspections.
