Tyler Schilling: Commitment to sustainable design is part of our DNA and operations. You can see this through our products that save energy and opera- tional costs, including demand control ventilation, use of electrically com- mutated motors, efficient make-up air units, our grease filters and more. What is demand control ventilation? TS: This technology, found with the Vari-Flow Air Management System, uti- lizes strategically placed heat sensors to monitor cooking and quickly adjust air- flow from the exhaust fan and make-up air unit to meet the cooking demand. Reducing airflow during slower periods of the day reduces electrical energy consumption and decreases heating and cooling loads. While most manufac- turers utilize duct-mounted sensors, we use a temperature sensor located in the hood's capture tank, which have shown up to a 5x faster response rate. Why is the response time important? TS: Temperature response time impacts the effective- ness of the systems turndown, which is how far fans can be slowed down and still maintain proper heat and smoke capture. Vari-Flow reduces airflow by up to 50% or more during idle cooking periods, generating exceptional electrical, heating and cooling savings. Additionally, it can be integrated into the facilities building management system through remote monitoring, allowing you to monitor energy savings and fan operation. How do electrically commutated motors work with this system? TS: The Vari-Green ® motor used in direct drive fan applications reduces maintenance with no belts to replace. They allow fans to be easily balanced for constant volume applications or for great turndown in demand controlled ventilation situations. Speed control is built directly into the motor so you can adjust the speed of fan with a simple turn of a dial or with a direct connection to Vari-Flow. Can the make-up air unit add to the operational savings? TS: Definitely! Accurex uses a patented barometric bypass damper that allows us to turn airflow down by up to 50% or more. Combine the improved efficiency of a demand controlled ventilation sys- tem with a Vari-Green motor and 50% turndown capability on the make-up air unit, you're maximizing the turndown, which maximizes energy savings. What energy savings can be gained with filters? TS: Our patented Energy Recovery Filter ties into energy savings, but also into maintenance and operational sav- ings. A heat exchanger incorporated in the hood filter, captures wasted heat created by cooking and uses it to pre- heat incoming cold water. Cooler filter temperatures condense more grease vapor and allows it to be captured, prevents baked on grease and reduces the frequency of filter cleaning. In some cases, grease filters can stay in the hood for up to a month. What are the benefits of self- cleaning hoods? TS: With the Auto Scrubber self-cleaning hood, both sides of the filters and the in- side of the exhaust plenum, are washed in place with water and detergent at the push of a button. This eliminates the need for daily removal of the filters for cleaning, which reduces labor, and reduces fire risk due to grease buildup. Q&A with Tyler Schilling, Product Manager, Accurex The Auto Scrubber hood dramatically reduces operating costs by decreasing frequency of filter, hood, and duct cleanings. With the ability to remove 88% of the grease particles at 8 microns, Energy Recovery Filters are great for medium to heavy grease loading applications while saving energy.
