Selection guides, application notes, and industry insights for pressure control professionals.
Comparing manual-adjustable Danfoss pressure switches (KP, RT) with factory-preset models (MBC). A quality inspector’s perspective on accuracy, flexibility, and real-world trade-offs for HVAC and industrial applications.
Danfoss pressure switch buyer's roundup — You’re staring at a refrigeration skid that keeps tripping on start-up. The compressor kicks, the pressure spike pegs the switch, and the contact opens three seconds too late—or too early.
Danfoss pressure switch buyer's roundup — The claim you hear everywhere: “A pressure switch is a pressure switch — just pick one with the right setpoint range.” That sounds practical, but it’s exactly the kind of shortcut that turns a £40 switch into…
Danfoss pressure switch buyer's roundup — You sized the pump right. You validated the system curve. But the pressure switch you spec'd keeps nuisance-tripping on transient spikes — so you crank the deadband wider, and suddenly your setpoint drifts 12%…
Danfoss pressure switch buyer's roundup — You sized a refrigeration circuit for 10 A continuous. The compressor starts, inrush hits 58 A, and the pressure switch either holds the setpoint or drifts by 3 psi—and that drift turns into a nuisance trip…
Danfoss pressure switch buyer's roundup — Opening myth: “Any industrial pressure switch will hold setpoint on a generator feed—the vibration and frequency drift don’t matter.” That’s a dangerous oversimplification.
Danfoss pressure switch buyer's roundup — The shelter is 20 ft2, the air handler cycles every 4 minutes, and the ambient dust load is high.
Danfoss pressure switch buyer's roundup — You hear it all the time in panel shops: “Get a pressure switch with more contacts — DP, DPDT, whatever — it’s more robust, it’ll last longer.” That’s one of those half-truths that sounds right until you look…
Danfoss pressure switch buyer's roundup — You spec a pressure switch in ten minutes. Five years later, that switch has cost you seven times its purchase price in downtime, service calls, and early replacement — if you picked the wrong one.
Danfoss pressure switch buyer's roundup — You're not selecting a pressure switch by the paint color on the housing. You're selecting it because a compressor kicks on at 150 psig, an evaporator fan draws 4 A, and the whole panel lives inside a 50 °C…
