PETD represents a new, disruptive technology in refrigeration. PETD evaporators perform the defrosting process 10 times faster with 90% less energy than current technology. The current defrost methods consume 12-25% of the total energy today’s refrigerators. Additional system-wide efficiencies produce overall energy savings of 25-33%.
Preliminary analysis by a large grocer indicates that the constant temperature provided by PETD technology yields an even greater economic benefit than the value of the energy savings.
A replacement PETD evaporator in a single standard 72cuft convenience/grocery display case refrigerator uses 25% less energy ($525.00/year @12 cents/kWhr). Since the cost of a new smaller PETD evaporator is less than the recycled value of the old one, minimal labor is the only cost of replacement.
PETD Evaporators up to 35% more efficient in refrigeration
Current refrigeration technology has not changed materially since 1930. The constant heating and cooling in conventional defrosting is not only energy inefficient, but also causes unnecessary appliance wear and tear. Furthermore, the temperature fluctuation caused by this cooling heating cycle also reduces food shelf life. For the average full grocery store, the value of increased food shelf life is greater then the energy savings.
