Overview

Heating commercial and institutional buildings in extreme cold climates can turn HVAC systems into massive “energy hogs,” driving up utility bills and straining operational efficiency. Energy recovery ventilation is vital for maintaining indoor air quality, but severe freezing conditions require smart frost mitigation strategies to maintain continuous, effective operation.

In this 20-minute AHR Expo presentation, Timin Musallam, Manager of Product Management at RenewAire, will explain how our latest Frost Control and Electric Preheat options deliver reliable frost protection during energy recovery ventilation.

Attendees will learn how this technology integrates directly with RenewAire’s commercial HE Series—including select indoor and rooftop configurations (HE07IN, HE07RT, HE10IN, HE10RT, HE15IN, HE15RT, HE20IN, and HE20RT)—to maximize cold-weather energy savings and streamline unit specification.

Key Learning Objectives

  • Cold-Weather Energy Load Reduction: Understand how electric preheat warms incoming outdoor air prior to the enthalpy core to prevent frost formation while preserving total energy transfer efficiency.
  • HE Series Equipment Integration: Explore design parameters and unit selection across key HE Series indoor (IN) and rooftop (RT) models.
  • Continuous Operation in Extreme Climates: Learn strategies to eliminate frost risk, avoid energy-intensive defrost cycles, and optimize operating costs in severe winter conditions.
  • Simplified Engineering & Specification: See how factory-integrated preheat solutions streamline controls coordination, electrical design, and field installation.

Product Spotlight: Factory-Integrated Electric Preheat

Designed specifically for cold-climate installations across Canada and northern U.S. states, the RenewAire Electric Preheat option conditions incoming sub-zero outdoor air before it enters the static-plate enthalpy core, raising temperatures just enough to prevent frost formation without sacrificing core energy recovery performance.

Core Engineering Benefits

  • Continuous 24/7 Balanced Ventilation: Prevents high-humidity exhaust air from freezing onto the core face without relying on exhaust-only defrost cycles, ensuring uninterrupted outdoor air delivery in severe winter weather.
  • Building Pressure Stability: Standard exhaust-defrost strategies create negative indoor air pressure in tightly sealed modern buildings, pulling cold air through envelope gaps. Electric Preheat maintains balanced supply and exhaust airflows, protecting building pressure profiles.
  • Modulating SCR Control: Features an open-coil heater element with modulating solid-state relay (SSR/SCR) control, primary automatic limit switches, and secondary manual reset safety switches (1–17 kW power range).
  • Single-Point Power & Simplified Installation: Factory-installed inside the unit cabinet with single-point electrical connection, eliminating field-installed duct heater labor, separate power runs, and extra job-site coordination.
