Daily wear and tear from lifting heavy equipment, up and down ladders all day, and working in extreme temperatures. Working as an HVAC technician can be as tiresome as it is rewarding. Luckily, having the right tool for the job can make any task easier.
Dwyer® products offer the perfect balance of functionality, safety, and durability.
The SMART Air Hood® balancing instrument, Series SAH, was designed to be lightweight and easily maneuverable. Because it’s on a pole, it can be raised and lowered without extra strain on your back and shoulders. The hood can be set up on a diffuser without having to hold it in place, making it possible for a single operator to balance a branch faster than traditional teams.

When walking through the grocery store and picking up a bag of flour or sugar, you’ve probably never thought about the process that it took to get these items packaged. The small particle size of these materials requires specialized handling to ensure there is minimal damage or loss, which is called pneumatic conveying.
A pneumatic conveying system works by moving the material through an enclosed conveyor line using a combination of pressure differential and the flow of air (or another gas) from a blower or fan. Pneumatic conveying systems can be used to transport cement, starch, sugar, salt, polymers, plastic powder, and other powdered/granular bulk materials. The two most common forms of pneumatic conveying systems are dilute phase and dense phase.

Jaguar. Ford. Ferrari. Three iconic automakers with storied racing pedigrees that have made some of the fastest and most beautiful cars in the world, each draped in a coat of paint of their own signature color: British Racing Green, Ford’s Grabber Blue, and Ferrari’s Rosso Corsa.

The earliest paint jobs were done by craftsmen such as furniture makers and carriage builders who applied varnish primers and oil-based enamel paints by hand. These finishes were inky, with low opacity and coverage, requiring multiple coats and lengthy drying times. And even with all that work involved, the paint would soon become brittle and start chipping away. Continue reading “Controlling Temperature in Paint Booth Heat Exchange Systems”
