Oven retrofit doubles production, halves
losses
HEET!BOX doubles the production rate and halves the energy losses of commercial convection ovens, yielding 50% reductions in the total costs of oven energy and labour time
Commercial convection ovens are useful for baking foods or heating metals, ceramics, etc These applications are not energy efficient, since much of the heat leaks out of the oven

State and federal teams are now pushing standards for ovens to gain energy efficiency; but many manufacturers feel that the upgrading of oven energy efficiency would bust their bottom line.
A simple solution is to lay a stack of spaced steel plates on the top shelf of an oven.
During the preheat, the airflow charges both the stack plates and the oven casing plates with equal heat, enough to bake twice the normal batch.
Also, the stack plates boost the ovens heat transfer rate to thrice that of the normal oven.
Easy fixes can stretch the ovens normal limits, such as the reheat time, bake load, or heat flow.
The best fix is to add more stack plates and decrease the airflow velocity.
Thereafter, the oven bakes with a generous heat and a gentle wind, avoiding parching, blistering or scorching.
The paradigm for "generous heat and gentle wind" came from the ancient "open-hearth" oven, which resembles a squat igloo made of stone blocks.
The blocks store massive heat, while the low domed ceiling minimises the airflow velocity.
For 5,000 years, the open-hearth oven has been the icon for fine baking despite its massive size, long preheating time, and high operating costs.
Today, with a HEET!BOX placed in your commercial convection oven, you can easily emulate open-hearth baking.
Economy In a continual run of bakes, the HEET!BOX doubles the production rate and halves the unit energy losses, yielding 50% reductions in the total costs of oven energy and labour time.
The data was tested daily for four years in a retail gourmet bagel shop.
The test bed used was a Blodgett Electric Oven, Model Mark V-111, w/2SP Fan Delay/Pulse options.
The HEET!BOX does not emit toxic gases, fluids, solids or other pollutants that abuse the environment.
It also holds heat, even if the oven air rushes out the door, wasted.
Many configurations are possible for improving thermal applications, their energy efficiency and environmental acceptability.
