Seresco Technologies, an indoor air quality equipment manufacturer in Ottawa, Ont., has started a dehumidifier training and certification school targeting facility maintenance personnel overseeing indoor pool dehumidifiers and heating, ventilation, air conditioning and refrigeration (HVAC/R) contractors servicing them.
Many indoor pool managers will inevitably face the challenge of replacing the dehumidification system at their facility. There are hundreds of commercial aquatic facilities in North America; YMCA Canada, which is one of the country’s largest pool owning organizations, has more than 40 indoor pools.
Seresco Technologies, an Ottawa-based manufacturer of indoor pool dehumidifier heating, ventilation, and air conditioning (HVAC) equipment, has moved into a larger headquarters, which will also house the company’s manufacturing and warehousing needs.
Sooner or later an indoor pool facility will require a heating, ventilation, and air conditioning (HVAC) system retrofit. For many hotels, community, and school pools built in the 1980s and early 1990s this is happening now because their HVAC systems are close to the end of their typical lifecycle, which is approximately 15 to 25 years.
Recent technological advancements in dehumidifier design are now being applied to 100 per cent outdoor air-based ventilation-only systems (OAVOS) for environmental control in natatoriums, and as a result, many facility operators are considering this equipment again for conditioning indoor swimming pool environments.
Canada has thousands of indoor swimming pools. Unfortunately, many of them are more problematic than facility operators would like to admit. Too often, the pool’s dehumidifier is blamed and the real cause of a natatorium problem is never discovered nor addressed. Chlorine odours, mould, condensation, or poor indoor air comfort, generally have causes unrelated to the dehumidifier. Instead, they may be due to building pressurization imbalances, improper vapour barrier, poor ventilation design, unbalanced water chemistry, or unsuitable architectural materials. They can also be related to inadequate maintenance, or perhaps just a slow, unnoticed degradation of operating parameters. Additionally, a few seemingly minor items missed during design and construction can also contribute to facility problems. Natatoriums have many unique design challenges and considerations that are not always obvious to anyone unsure about these facilities’ state-of-the-art requirements.
