No, you do not have to start each one separately, each HT-200 controller comes with a "bus communication mode", optionally you can choose to install an HMI (operator screen) that connects all HT-200 and one-touch start all of HT-200. As a result, you will only have to program the temperature recipe and desired cycle time. It is also possible to program specific cooking zones. For example: oven inlet zone 1/100F and zone 2/130F and zone 3/150F, etc.
Electric lamps have no uniformity of temperature on the room in question, similar to the lighting provided by a neon office light for example. The lamp does not control the temperature of the substrate, providing a mix of warm and cold areas. Electric lamps require a lot of maintenance and are not allowed to be used in a place with solvents and / or paint shop because they present a danger for fire or an explosion. The only advantage of electric lamps, they are not expensive. But in return, they do not work well with liquid paints.
The HT-200 is significantly less hot than electric lamps. The HT-200 has the advantage of cooking the paint from the inside-out. In comparison, electric lamps are use too much heat and have a short wavelength of 0-2 microns plus 4000oF, similar to the sun's rays. With that in mind, the waves of electric lamps enter the reflection, wrap along the surface and trap either water or solvent. In addition, they create a crust on the surface, giving a false impression that everything is dry. The next day, water or solvents surface and create problems such as scratches, products sticking together or packaging issues.
Yes, you can control the temperature. Each transmitter comes with a pyrometer (a camera) that measures the temperature of the substrate continuously at plus or minus 3 degrees F substrate.
Our products run on electricity and gas. There is a pre-heating period of 15 minutes at start-up in the morning (1 kWh). With a 20-pound, BBQ-like propane tank, you'll get 41 hours of continuous operation alongside the 24-volt electric controller.
