Building codes distinguish between cooking processes that create smoke and grease ( e.g., frying, charbroiling or griddling ) and those that produce only heat and moisture ( e.g., steaming, baking and dishwashing ) Cooking that produces smoke and grease requires a Type I hood, commonly referred to as a grease hood, which includes liquid tight construction, liquid tight exhaust duct and an automatic fire suppression system. Operations that produce only heat and moisture requires a Type II hood, commonly referred to as a heat or condensate hood, which does not require liquid tight construction, liquid tight ductwork or a fire suppression system.
Grease hoods are typically constructed of 430 or 304 polished stainless steel, liquid tight construction complete with baffle type grease filters and a grease trough with removable grease cup. There are several styles of grease hoods with varying construction features. Wall mounted canopy hoods, island ( single or double ) canopy hoods and proximity ( backshelf, pass-over or eyebrow ) hoods all have different capture areas and are mounted at different heights and horizontal positions relative to the cooking equipment and listings.
Grease exhaust ducts are to be fabricated of min. 16 gauge steel or 18 gauge steel welded liquid tight, per code. Atlantic Coast Restaurant & Mechanical Services chooses to fabricate our exhaust ducts from 16 gauge galvanized steel because we have found it to be superior to regular steel and ultimately a better product to install for our consumers. Our exhaust ducts are specifically designed to meet the needs of our clients and vary from project to project. All ductwork is designed using computer aided programs, cut out of sheets using plasma cutting systems and formed using metal forming machinery.
Supply ducts, for most typical hood systems, are typically fabricated of min. 26 or 24 gauge galvanized steel, Pittsburgh Construction.
There are two typical types of exhaust fans for the removal of grease laden vapors, an upblast exhaust fan, typically found mounted on rooftops or walls and a utility set exhaust fan, typically used inline or on rooftops. Upblast fans are constructed of aluminum, where utility set fans are constructed of steel. Both are acceptable for the removal of grease laden vapors, just used in different types of installations.
Supply fans are designed to bring back approx. 80% to 90% of the air being exhausted. There are two typical types of supply fans used in bringing back or introducing air back into the kitchen. The typical box style fan is typically found mounted on rooftops or walls and an inline fan, typically used inside the building. Fans are typically constructed of steel or aluminum boxes with a blower and motor section mounted inside.
Atlantic Coast services offers a full service line of "walk in coolers" at a very affordable cost. Our lines include walk-in coolers, walk in freezers, beer coolers, convenient store merchandisers and cold storage warehouse rooms.
Atlantic Coast Services offers walk in freezers at the highest quality for the best value. Shipping and installation is available anywhere. We use top brand refrigeration systems.
Cooler Floors are made of 22 ga Smooth Mill Floor Plate, 4” Extruded Polystyrene Foam (EISA 2007 Approved), NSF gasket with Cam-Locks hardware and Built in ramp.
To reduce condensation due to high humidity, insulation is installed under concrete floors. If your cooler will be installed on a wood surface, a cooler floor is necessary to avoid condensation that will rot out the wood floor. Insulation is required on a concrete floor for a freezer. Installations are done according to local codes. When a ramp is in use, we re-enforce doors and floors.
