Dectron Pool Unit Nightmare: High Head Pressure!

A commercial Dectron pool dehumidifier is overheating the room, but the site managers say the boiler isn't to blame. Join me as we trace out this complex refrigeration network—checking reheat coils, coaxial heat exchangers, bypass check valves, and head pressure controls to track down the root cause. Join me on this service call as we walk step-by-step through: • Tracing discharge gas through reheat & bypass valves• Finding hidden bypass mistakes left behind from previous work • Using wireless probes to verify temperature drops across reheat vs. condensing loops • Inspecting shredded belts and discovering severely worn motor pulleys • Restoring proper airflow and dialing in head pressure controls — Purchase your tools at https://www.trutechtools.com/home?aff=13 and use the offer code SURVIVAL to save 6% on your total purchase (exclusions may apply) — 💥 Amazon Store: https://www.amazon.com/ref=as_li_ss_t...
