How to balance rising energy costs with profitability? Biggest energy users for restaurants*: –Cooking: 45% of Natural Gas usage –Water heating: 28% –Space Heating: 27% Successful restaurateurs: using ingenuity to save energy *Managing Energy Costs in Restaurants (2010), retrieved11/17/2010 from: A Common Problem: Energy Consumption

Ingenuity Saves Energy Dragon Fire Thermo Recovery Filters ™ convert exhaust heat from your kitchen grill into energy for heating water or make-up air.

Ingenuity Saves Energy: Dragon Fire Thermo Recovery Filters ™ Combination grease filter and heat reclamation device Converts up to 60% of exhaust heat into energy for heating water or make-up air Replaces conventional grease filters

How does it work? Heat from the grill passes through Dragon Fire’s ™ specially designed grease filter and over the Teflon ® coated copper heat exchanger Heat is transferred to the water flowing through the heat exchanger’s tubing Pre-heated water is pumped to a water heater for final heating OR to an air handler for use in heating make-up air Dragon Fire preheated water:100° to 125°F=FREE HEAT

What are the benefits? Superior grease collection: –2 filter stages trap more grease: lower emissions –Liquefying action of heat exchanger sends more grease to the trough: less maintenance –Exceeds UL requirements: collects 14 times more grease in the trough than the filter* * UL requirements stipulate that 4 times more grease must be collected in the trough versus the filter. UL testing for Dragon Fire Thermo Recovery Filters™ was conducted without water running through the heat exchanger. In further testing with unheated water running through the heat exchanger, the Dragon Fire Thermo Recovery Filter™ showed a grease collection ratio of 35 to 1 and higher).

What are the benefits? Durable Construction, Flexible Design –Heavy gauge stainless steel filter, baffles, and connectors –Teflon ® coated copper heat exchanger –3/8 in. NPT inlets and outlets allow for easy installation of multiple units –Available for retrofit or new construction

What are the benefits? Low-cost: DIY maintenance/cleaning Teflon coated heat exchanger: non-stick for easy grease removal Wash by hand or via high temp dishwasher Quick connect heat exchanger hook-ups snap on| and off for easy removal, cleaning, and reconnection

What are the benefits? Green Water/Make-up Air Heating Technology –Heats water or make-up air using only the heat produced from the cook line –Environmentally sustainable, reduces energy usage, and saves money –Excellent ROI: saves approx. $6,900/yr on water heating costs –Quick installation payback: 2 years or less

A ‘Common Sense’ Solution: Dragon Fire Thermo Recovery Filters ™ Maximizes your energy dollars: recycles cooking exhaust into energy for heating. A cost-effective, eco-friendly solution with excellent ROI and payback Built to last for retrofit or new construction Superior grease collection, easy cleaning The hotter and busier the grill, the more savings!
