AHR Expo 2027 Presentation: ERVs, Frost Control, and Electric Preheat for Extreme Cold Climates
Discover how advanced Frost Control and Electric Preheat options integrate with RenewAire HE Series ERVs to provide reliable frost protection and maximize cold-weather energy savings.
Overview
Heating commercial and institutional buildings in extreme cold climates can significantly increase HVAC energy costs. At the same time, energy recovery ventilation helps maintain indoor air quality, freezing temperatures present additional challenges. Therefore, effective frost control is essential for reliable system operation.
At the AHR Expo HVAC convention, Timin Musallam, RenewAire’s Manager of Product Management, will present the latest Frost Control and Electric Preheat options for commercial energy recovery ventilation systems.
Attendees will learn how these solutions protect energy recovery ventilators (ERVs) from frost formation. In addition, the presentation will explore ways to improve cold-weather performance while reducing energy costs.
HE Series ERV Integration
RenewAire’s Frost Control and Electric Preheat options integrate with select commercial HE Series ERVs. Specifically, these include both indoor (IN) and rooftop (RT) configurations:
Together, these solutions help engineers optimize cold-weather energy savings and simplify equipment specification.
Key Learning Objectives
Cold-Weather Energy Load Reduction: Learn how electric preheat warms outdoor air before it reaches the enthalpy core. As a result, this helps prevent frost formation while preserving energy recovery efficiency.
HE Series Equipment Integration: Explore design considerations and equipment selection for HE Series indoor (IN) and rooftop (RT) models.
Continuous Operation in Extreme Climates: Discover strategies to prevent frost formation, avoid energy-intensive defrost cycles, and reduce winter operating costs.
Simplified Engineering & Specification: Understand how factory-integrated preheat solutions simplify controls coordination, electrical design, and field installation.
Product Spotlight: Factory-Integrated Electric Preheat
For cold-climate installations across Canada and northern U.S. states, the RenewAire Electric Preheat option helps prevent frost formation in energy recovery ventilators (ERVs).
To prevent frost buildup, the system warms incoming sub-zero outdoor air before it reaches the static-plate enthalpy core. As a result, it helps prevent frost buildup while maintaining energy recovery performance.
Core Engineering Benefits
- Continuous 24/7 Balanced Ventilation: Prevents humid exhaust air from freezing onto the core face without exhaust-only defrost cycles. Consequently, outdoor air delivery can continue during severe winter weather.
- Building Pressure Stability: Traditional exhaust-defrost cycles can create negative indoor air pressure, drawing cold air through building envelope gaps. In contrast, Electric Preheat maintains balanced supply and exhaust airflow to support stable building pressure.
- Modulating SCR Control: Features an open-coil heating element with modulating solid-state relay (SSR/SCR) control. In addition, the system includes primary automatic limit switches and secondary manual reset safety switches. Available power ranges from 1–17 kW.
- Single-Point Power & Simplified Installation: The factory-installed heater features a single-point electrical connection inside the unit cabinet. Therefore, separate field-installed duct heaters and additional power runs are unnecessary, simplifying installation coordination.
