Commercial Scale ESP with Automatic Cleaning

Powerclean™ commercial scale, auto-wash electronic precipitators (ESP) eliminate the offensive smoke, grease & cooking odour emissions produced by commercial kitchens.

Kitchen Exhaust Air Cleaner: Smoke, Grease & Cooking Odour Solutions

Offensive smoke, grease and cooking odour emissions are all real issues facing designers and owners of commercial kitchen sites. Reliable kitchen exhaust abatement systems that include electronic precipitators (ESP’s) to effectively remove airborne contaminants are essential, especially when air and noise quality expectations are so high.

Selection of the most appropriate kitchen exhaust abatement system for any given site is complex and due consideration must be given to the following:

  • The type of cooking being undertaken,
  • The required air and noise quality result,
  • Installation parameters of the required equipment,
  • Capital costs for the required equipment and system installation;
  • And most importantly, the ongoing operation and maintenance costs for the site owner.

Automatic Wash ESP’s: The More Efficient Proposition for Large or Multi-Kitchen Exhaust Applications

Typically, there are two types of ESP’s available; manual wash, in-duct type ESP’s and auto wash, large scale or plant room type ESP’s.

Manual wash, in-duct type ESP’s are typically a low capital cost investment, with a higher ongoing maintenance cost, due to the labour intensive frequent manual wash and ESP cell replacement requirements. This option may be economical for small commercial kitchen applications with low exhaust airflow requirements, but are impractically expensive to operate and maintain in large or multi-kitchen exhaust applications where multiple streams of exhaust join into one system.

Automatic wash, large scale or plant room type ESP’s are typically a high capital cost investment, with an extremely low comparative maintenance cost, due to the inbuilt automatic cleaning of the ESP cells. For high exhaust level applications where multiple streams of exhaust join into one system, a large scale ESP with automatic cleaning is the more efficient proposition from a cost of ownership perspective.

A typical automatic wash ESP system utilises electronic air cleaning technology, whereby dirty kitchen exhaust air is drawn into the unit and goes through a pre-filter that collects large airborne particulates, then all airborne particulates including microscopic smoke and grease particles are electrically charged (positively) as they pass through a high voltage ionizer. These charged particles are attracted and adhere to a series of parallel collecting plates (collection cells), which form the negative elements of an electrostatic field, removing the airborne contaminants from the air stream. An optional odour control system removes cooking odours and a self contained automatic wash system routinely cleans the collection cells. From a maintenance perspective, routine replacement of the pre filters, collection cells, odour control filters and automatic wash detergents are required.

The PowerClean™ Cost and Performance Advantage

The Air Scrubbers Inc. PowerClean™ is a large scale or plant room type ESP with automatic cleaning used to control process generated airborne contaminants such as smoke, grease and cooking odours produced in commercial kitchens. Designed specifically for superior and dependable, continuous duty operation with minimal maintenance requirements and low operating costs, the PowerClean™ incorporates unparalleled innovations to become the most reliable and efficient new generation ESP system on the market.

Unlike typical automatic wash ESP systems, the new generation PowerClean™ includes the following key features:

Constant airflow resistance of Pa – PowerClean™ maintains a constant and reliable air flow resistence that prevents unwanted fluctuations in the system air volume. The extremely low airflow resistance of <65*Pa result in reduced fan Kw requirements and energy savings.

Reliable ionizer construction – PowerClean™ utilises rugged ionizing electrodes made from rigid stainless steel that conducts a high frequency electronic charge. This sturdy construction is more reliable than the fragile ionizing wires or insulators used in less durable ionizer designs.

Permanent aluminium collection cells – PowerClean’s unique permanent collector cells are designed to last the lifetime of the system and save on maintenance costs because they never need to be replaced. A combination of deep cell design and highly conductive low gauge aluminium plates ensures high efficiency particle collection that is delivered instantly and continuously for superior performance with long service intervals.

Safe, reliable and fast recovery power supplies – Downtime on power supplies renders the ESP cells ineffective. PowerClean’s superior and robust electronics delivers reliable operation and split second recovery from momentary arcing due to heavily contaminated particles in the air stream.

Instant and constant specified efficiency – PowerClean™ provides superior, dependable operation by delivering instant and constant specified efficiency particle collection from the moment the system initiates. A targeted, efficient airflow path directly into the collection cells eliminates by-pass to ensure the specified efficiency is achieved in a single pass.

Improved, built-in automatic cleaning and PLC controls – PowerClean’s integrated automatic cleaning system provides complete, effective wash-in-place cleaning and drying of all ionizer-collector cells, assuring optimum performance and maximum system reliability. A user friendly programmable logic control (PLC) initiates all system functions automatically at a predetermined schedule or with a manual push button.

Safety filter for peace of mind – PowerClean™ includes a high efficiency safety filter as backup for your peace of mind.

Bonded carbon panel filters for odour control – Optional bonded, activated carbon filters utilise large carbon volume for long life and assured odour removal, configured for low pressure drop to save energy.

Custom blower / motor packages – Optional custom blower/motor and motor starter packages are tailored to meet the specific air volume and static resistance requirements of your site to ensure superior and dependable system performance.

Flexible system configurations – PowerClean™ is available in side access units with left or right handed access doors for use with central handlers or as a stand alone fan powered unit. Standardly a factory assembled and packaged system, PowerClean™ can also be flat packed and assembled on-site for retrofit applications.

65 Pa value includes safety mesh filter and ESP at max. nominal flow. Average values for entire system including carbon and pre-filtration are
