The Benefits of Compressor Based Dehumidification

Reduced Operating Costs

Reduce energy costs by 1/3 compared to constant OA systems.

Reduced Maintainance Costs

When you dramatically reduce the corrosive chemical levels you save money on associated maintenance issues.

Reduced Carbon Footprint

This system has the smallest energy footprint, reducing your carbon footprint to the absolute minimum.

Improved IAQ

With an integrated source capture solution, effectively removes chemicals from the source.

Peak Performance

Your athletes will perform at their absolute best when swimming in a better environment.

Green Dehumidification Design

This system has the lowest refrigerant charge in the industry.

5 Common Myths of Ventilation Based Dehumidification

The following myths used to sell 100% OA can cost you money, yield dissapointing IAQ, and overall comfort.

Indoor Air Quality Comparison
Dilution VS. Source Capture

No Air Movement

Chloramines are 4 times denser than air, leading them to settle on the pool surface or “breathing zone”, like a layer of scum, in the absence of any air disturbance.

Ventilation Based Dehumidification

The Dilution approach to indoor air quality requires bringing in large volumes of outside air, targeting the pool surface. This causes the chloramine layer to be disturbed and absorbed into the rest of the room, before finally being exhausted.

Compressor Based Dehumidification

Source Capture introduces a gentle air current at the pool surface level, which exhausts the chloramine-laden air “at the source”, without distributing the chloramines throughout the pool room. Dehumidifiers manufactured by PoolPak can be specified with the Source Capture ready option.
