Mastering the thermal requirements of cold storage warehouses in Québec is a major technical challenge. At AirGreen, we understand that these specialized environments demand high-level HVAC commercial expertise, not only to maintain precise temperatures but also to optimize energy consumption, meet sanitary standards, and ensure the preservation of sensitive products. This comprehensive article offers an in-depth analysis of commercial heating solutions for cold storage warehouses, with a focus on best practices, effective technology choices, and our hands-on experience with projects completed in Montréal, Laval, Longueuil, the North Shore, and the South Shore.
Why Heating Is Crucial Even in a Cold Storage Warehouse
Contrary to popular belief, cold storage warehouses don’t just require cold. Areas like work zones, loading docks, or temperature-controlled rooms need stable and moderate temperatures. Heating is therefore essential to:
-
Maintain safe and comfortable working conditions for employees.
-
Prevent condensation and temperature swings that can damage products.
-
Ensure precise thermal regulation in mixed-use areas (receiving, shipping, dry storage).
-
Reduce risks of corrosion, mold, or frost caused by extreme temperature differences.
The Technical Challenges of Heating in a Cold Storage Warehouse
Heating in this type of facility involves unique constraints:
-
Very large air volumes that need targeted heating.
-
High ceilings, which lead to significant vertical heat loss.
-
Building envelopes insulated for cold, making dew point control delicate.
-
Constant traffic flow (industrial doors, loading bays), allowing cold air to enter frequently.
-
Mandatory integration with existing refrigeration systems.
Our Commercial Heating Solutions Tailored to Cold Storage Warehouses
At AirGreen, we’ve developed a custom technical approach to meet the specific demands of refrigerated warehouses. Here are the technologies we frequently install and recommend:
1. Natural Gas Forced Air Heating Systems
For large spaces, suspended or wall-mounted natural gas unit heaters are robust and cost-effective solutions. We often install high-efficiency Modine or Reznor units, capable of evenly distributing heat throughout large spaces with zone-specific thermostats.
2. High-Capacity Commercial Heat Pumps
The evolution of industrial heat pumps allows us to now offer reversible models like the Bosch BOVA 5 Ton or the FUJITSU KXHA with R-32 refrigerant, which are particularly effective for buffer zones or offices within warehouses. These units provide both winter heating and summer cooling while delivering excellent seasonal energy efficiency ratings (SEER and HSPF).
3. Thermal Air Curtains for Transfer Zones
We also install heated air curtains at loading dock doors. These devices reduce thermal losses and improve sealing in critical areas while providing localized heating. The effect is immediate: improved worker comfort and reduced energy consumption.
4. Radiant Tube Heating
For some layouts with large open areas, we recommend installing gas-powered radiant tube systems. These tubes heat people and objects directly without unnecessarily heating the ambient air. This ensures maximum efficiency in poorly insulated or high-loss environments.
Case Study: Heating Installation in a Cold Storage Warehouse in Longueuil
We recently completed a full HVAC installation in a cold storage warehouse specialized in pharmaceutical products in Longueuil. The challenge: maintaining a stable temperature of 18 °C in transit zones while perfectly isolating cold rooms at -20 °C.
Solutions implemented by AirGreen:
-
Installation of two 200,000 BTU Reznor forced air units with independent zone controls.
-
Installation of Berner air curtains with integrated heating above each loading dock.
-
Integration of heat recovery systems on the refrigeration units to provide free heating for work areas.
-
Networked central control system (BACnet) to adjust temperatures and monitor consumption in real time.
Result: a 22% reduction in annual energy costs, improved comfort for employees, and constant temperatures in sensitive areas, even in the peak of winter.
