PTC-Series
Mutiny® PTC / CPTC
Pump-trap combination that traps under positive differential and pumps when the equipment stalls.
Product overview
PTC and CPTC combine condensate pumping and steam trapping in one arrangement, so a single installation covers both operating regimes of a modulating heat exchanger — draining normally when pressure allows, and pumping when it does not.
The problem it solves
On equipment with a modulating steam inlet, the steam-space pressure falls as the control valve throttles. Below the point where it can overcome the return-line backpressure, condensate stops leaving. The exchanger floods, control becomes unstable and the tubes are exposed to waterhammer and corrosion. This is the stall condition.
Working principle
While the steam-space pressure exceeds the backpressure, the unit passes condensate as a trap. When differential is lost, the float admits motive steam or air and the same body displaces the accumulated condensate into the return line, then vents and refills.
Applications
- Heat exchangers and reactors with modulating steam control
- Temperature-controlled equipment prone to stall
- Submerged coils and jacketed vessels
- Installations where a separate pump and trap are impractical
