Seresco USA Inc. has introduced the Outdoor Air (OA) Series of indoor split dedicated outdoor air system (DOAS) dehumidifiers.

The OA Series uses Seresco's Protocol Technology, which substitutes HFC refrigerant with less environmentally-friendly glycol for heat rejection to an outdoor dry cooler in all commercial applications. The company says that by substituting refrigerant and its copper line sets with glycol and PVC piping helps to simplify installation and reduces onsite labor/material costs by 60% to 75%.

The OA Series ranges from 6 to 30 tons and 1,000 to 6,000 cfm (dependent upon geographical humidity conditions). Seresco says the OA concept complements applications such as VRF and active chilled beam designs looking for indoor split systems for treating outdoor air.   

Besides Protocol Technology, every OA Series unit includes other Seresco features such as fully-dipped corrosion-resistant coils, high efficiency electronically-commutated (EC) motor/fans, and unit configurations that separate critical components/controls from the supply air stream. Another standard feature is Seresco's WebSentry®, a web browser-based software/hardware application that monitors and transmits over 100 operating parameters, including compressor pressures, from the onboard CommandCenter™ microprocessor controller to authorized smart phones or email. WebSentry's 24/7 monitoring aims to ensure optimum energy efficiency and reliability throughout the unit's lifecycle.
