About Head Pressure Controls
You may not think it, but many air conditioning systems have to work just as hard in cold weather—especially in well insulated buildings and commercial spaces with lots of heat-generating equipment and machinery. And that’s where head pressure controls come into play: in low ambient conditions, they regulate system pressure in HVAC systems, helping to prevent freeze-ups and low-pressure cutouts. They also fight against liquid-slugged compressors, all of which can lead to the loss of perishable goods and expensive downtime.
