Custom Natatorium Dehumidification ERU for Healthcare

This featured XeteX project is a custom Natatorium Dehumidification Energy Recovery Unit for a healthcare application with split unit construction for transportation. Unit weight, unit dimension, duct locations and electrical load were critical in the design.custom pool eru

XeteX supplied multiple ERUs at a large Midwest aquatic facility. The main pool space is served by 144,000 CFM of air divided into three units operated in a master/slave configuration.

The dimensions of the larger units required that they be split into multiple sections for shipping. Instead of the typical “sliced bread” approach to unit splits, XeteX engineered a single split along the length of the unit. The main benefit of this custom feature was that all refrigeration circuits could remain intact during shipment and no field piping was required.
