Pollution Control Units

UL 8782 Pollution Control Units (PCU) for Commercial CookingListed to the new commercial cooking PCU standard, the Greenheck Grease Trapper and Grease Trapper ESP have been rigorously tested to ensure proper mechanical and electrical operation, to provide the utmost safety to the building and its occupants.

With the increasing size and density of the urban landscape, the focus on clean air, and multi-use buildings, restaurant exhaust odor and grease control play an increasingly important role in commercial kitchen systems. Condo, apartment or hotel room occupants do not want to be subject to the odors from restaurants.

Greenheck’s Grease Trapper™ and Grease Trapper ESP™ Pollution Control units are specifically designed to eliminate both smoke and grease particles from a kitchen exhaust system, while odor control modules eliminate the remaining odor.

Grease Trapper™

The Grease Trapper pollution control unit uses a four-stage mechanical filter arrangement to remove grease and smoke particles from the exhaust air at an economical initial cost. The Grease Trapper incorporates pure carbon tray filters to remove odor molecules prior to discharging the air, reducing the impact of the kitchen exhaust to the surrounding area.

Metal mesh filters are easily washable with a hose or in a dishwasher and catch the large grease particles

MERV 8 pleated filters remove particles from the incoming airstream to protect high efficiency filters and minimize maintenance

MERV 15 pleated final filter ensures a minimum overall particulate removal efficiency of 95%

1” carbon trays reduce cooking odors

A pressure switch enclosure is provided to house all of the individual pressure switches for ease of maintenance and wiring on the unit. The pressure switches monitor each individual filter bank and a remote filter status indicator panel advises maintenance staff when each filter stage requires replacement.

The Grease Trapper ESP Pollution Control Unit uses electrostatic precipitator modules and carbon filters to remove grease, smoke and odors from the exhaust airstream. UL listed to both UL 8782 - Pollution Control Units for Commercial Cooking, and UL 867 - Standard for Electrostatic Air Cleaners solidifies the Grease Trapper ESP as one of the safest pollution control units in the market.

The automated wash down sequence allows for the grease buildup on the ESP collector plates to be easily removed with the touch of a button or on an automatic daily schedule.

The unique construction of the Grease Trapper ESP allows for the smallest clearance to combustibles in the industry. It can mount within 12-inches (305 mm) of combustibles on the top of the unit and 6-inches (152 mm) on the sides and bottom to easily fit it into tight mechanical rooms or ceiling spaces.

UL 8782 Pollution Control Units for Commercial Cooking

• Under this listing, the unit is tested under extreme loading conditions, similar to how grease ductwork is tested. This listing details pollution control unit specific construction, material and electrical requirements to ensure the safety of the building and its occupants.

• International Mechanical Code (IMC) 2021 will require all pollution control units installed in commercial cooking operations to be listed to UL 8782.

Durable ESP Cells• Lightweight cells allow for easier handling and removal from unit

• Universal cell size eliminates the possibility of loading cells in the wrong order or position

• Thermoset isolators provide improved reliability and reduced weight, unlike ceramic isolators that can break easily

• Stainless steel spiked blade ionizer improves reliability and will not break easily like tungsten wire systems

• Cells have been third-party tested to ensure the highest performance and efficiency

How it WorksAs air enters the ESP module it passes through an ionizer that positively charges the particles in the airstream. Upon entering the charged collector portion of the cell, the positively charged particles are attracted to the negatively charged plates like a magnet, which captures and removes the contaminant from the airstream. This eliminates the need to change out costly filters and lowers overall maintenance requirements.

UL/cUL Listed to UL 867 Electrostatic Air Cleaners Standards

• UL 867 is a safety standard for the electronics of Electrostatic Air Cleaners and more specific for the Power Supply and ESP Cell assemblies. The Grease Trapper ESP electrical assemblies were tested to UL 867 Standard requirements and meets or exceeds the standard as listed.

6 Detergent injection manifold – pre-engineered assembly for water, detergent injection and mixed wash to unit wash inlet

7 Drain outlet (2”) part of manifolded system pre-assembled from the factory, so only one drain is connected in the field.

8 Inlet hot water connection from detergent manifold for automatic washdown system

9 Impingement filter evenly distributes airflow and stops large particles from entering the system. These filters are washed, unlike other precipitators on the market

10 Automatic wash down uses detergent from five-gallon tank to clean the entire cell. Reduces the need for manual cleaning

11 Pre-piped UL 300 fire system

12 V-bank “2” carbon trays for reducing cooking odors
