Pollution Control Unit (VPCU)

System Overview

The Pollution Control Unit, VPCU Series, is a mechanical filter arrangement for the removal of smoke and grease particulate from the exhaust air stream of kitchen exhaust systems. The typical VPCU includes a washable steel pre-filter and disposable, high efficiency (MERV 15) media filter. An additional high efficiency (MERV 15) / HEPA module is available for smoke control. Odor control is handled via an optional module ( typically 50/50 blend carbon/permanganate OR 100% carbon blend). Sizes range in capacity up to 20,000 CFM.

The VPCU is ETL listed and is suitable for indoor or outdoor installations.

Advanced Filter Monitoring System (Optional)

The Pollution Control Unit (VPCU) with Advanced Filter Monitoring option offers and automated assessment of the unit to ensure proper operation.

System Overview

The Advanced Filter Monitoring includes a module that provides the necessary precision pressure measurements for accurate monitoring of the complete system. Based on the measurements, the module will then initiate actions via the electric control package and give readings to the user. Direct access to the operating conditions are provided through the use of an HMI (human machine interface), which is conveniently located in the VPCU.

System Features & Advanced Filter Monitoring Benefits

• Sustainability — Extends life of various filters, address specific filters which need replacement based on monitoring
• Ease of Installation and Startup — automatic calibration of the system via HMI
• Maintenance — Provides advanced notice, pinoints specific faults to address
• Reliability — Ensures proper operation of the VPCU
• Monitors Pressure Drop across each filter module of the VPCU
• Missing Door or Missing Filter Indication — fans and cooking equipment will shut off if faults indicated
• Detects Filter Saturation Percentage

Electrostatic Precipitator (ESP)

System Overview

An electrostatic precipitator (ESP) is an electronic air cleaner that charges the dirty air stream to a high level and collects the particles on metal plates, removing particles from the discharge. ESP cell(s) inside the module are comprised of metal plates and ceramic isolators for durability. Our ESP has an integrated self-cleaning system to reduce maintenance costs associated with comparable mechanical-type filters.

ESP Benefits

• Less Maintenance – Self-cleaning system reduces filter maintenance
• Lower Pressure Drop – Lower pressure drop than comparable mechanical filters
• Engineered to Your Needs – Flexible filter module configuration
• Superior Durability – Spiked rigid plate ionizer ensures superior durability; more durable than wire-type ESPs
• Powerful Ionization – 104 watt power supply with +13kVDC output
