The modern way of life depends on refrigeration equipment for the preservation of food and for human comfort. Many industrial and commercial processes, such as printing, textile manufacturing, food storage, etc., are heavily dependent on the proper conditioning of air for efficient, economical operation of the necessary equipment. The air conditioning and refrigeration field… Read More »
The maintenance for large electrical heating systems may include either panel type, baseboard type, or forced air. The panel and baseboard systems do not require much maintenance when properly installed. Baseboard heat has more air circulation over the elements that the panel type, so the units must be kept dust free. Some… Read More »
Electric heat is produced by converting electrical energy to heat. This is done by placing a known resistance of a particular material an electric circuit. The resistance has relatively few free electrons and does not conduct electricity easily. Resistance to electron flow produces heat at the point of resistance. One type of material… Read More »

Relays / Contactors are nothing more than a switch. In heating and cooling, these relay/contactors are used to turn on high voltage components such as motors, compressors, and other high voltage components. When a thermostat reaches a set temperature, a transformer, usually 24 volts, energizes the contactor, which has a coil built into it. When… Read More »
