3–4 minutes

This article discusses the potential upgrades and costs associated with replacing a brand name dehumidification system like Dectron: Dryotron, Seresco, or Poolpak. We want to provide clarity on the installation process and what you can expect. Our Dectron price list is listed below.

What makes up an indoor pool dehumidification system?

Indoor pool dehumidifiers from brands like Dectron, Seresco, or Pool Pak are not only responsible for dehumidifying the air in an indoor pool room, impressively, they are innovative thermal energy recyclers which efficiently harness the traditional refrigeration cycle.

You’ll usually find external auxiliary heating systems connected to the indoor pool dehumidifier. These auxiliary systems are usually boilers or electric heaters which increase heating capacity and thus reduce the stress load on your indoor pool dehumidifier. A boiler or electric heater provides additional heating capacity for the air and the pool water.

Depending on the condition of these external systems, it may make sense to also update or replace parts such as:

  • Pool water heat exchanger
  • Boilers
  • Air heat coil
  • Circulation Pumps
