Introduction: The Rising Demand for Summer Cooling
As summer temperatures rise across the UK and Europe, maintaining comfortable and safe working environments in industrial and commercial buildings has become more critical. Warehouses, factories, and large retail spaces are especially vulnerable to overheating, which can affect not just worker well-being but also machinery, processes, and overall productivity.
Temperature control is no longer a seasonal afterthought; it’s a key factor in health, safety, energy efficiency, and operational continuity.
Enter Reznor, a trusted leader in HVAC innovation for over a century. Known for robust, efficient climate solutions, Reznor now brings its expertise to the forefront of smart summer cooling, offering adaptable technologies designed for today’s evolving climate demands.
Why Cooling Matters More Than Ever
Rising indoor temperatures can have significant consequences in large-scale environments:
- Employee Discomfort: Heat stress reduces concentration, increases fatigue, and raises the risk of accidents. Keeping indoor temperatures at optimal levels is essential for workforce productivity and wellbeing.
- Machinery Performance: Excessive heat can disrupt sensitive equipment and processes, risking delays, defects, or even equipment failure.
- Rising Energy Bills: Poor air circulation and inefficient cooling force HVAC systems to work harder, increasing operating costs and energy consumption.
As businesses focus on sustainable operations and year-round climate control, the demand for adaptable, efficient cooling solutions has never been higher.

Key Cooling Technologies That Deliver Results
Reznor offers smart cooling products engineered to maintain temperature balance, reduce hot spots, and ensure comfort across large indoor environments.

E+ Dual-Mode Electric Heater with Summer Fan Mode
The e+ electric heater isn’t just for winter. It operates in fan-only mode in warmer months, providing efficient air circulation without heating. This dual-function design supports year-round use, helping reduce the need for additional cooling systems in moderate climates.
- Ideal for: Workshops, retail units, and mixed-use commercial spaces
- Key benefit: Efficient use of existing infrastructure with low energy draw in summer

LIRA – High-Efficiency Air-to-Air Heat Pump
The LIRA is a whisper-quiet, compact heat pump for high-performance cooling and heating. It offers energy-efficient summer cooling using low-GWP refrigerants, making it ideal for businesses focused on sustainability.
- Ideal for: Small to large commercial and industrial areas
- Key benefit: Quiet operation and minimal installation footprint

Destrat Fans – Air Recirculation for Balanced Temperatures
When ambient or cool air is already in place, Reznor’s destratification fans circulate refreshing air from high level to ground level. While traditionally used in winter to conserve heat, they’re equally useful in summer for reducing hot zones and maintaining consistent airflow.
- Ideal for: Warehouses, sports halls, and high-level buildings
- Key benefit: Cost-effective, low-maintenance solution for thermal balancing

EuroT+ – Versatile Air Handling with Optional Cooling
The EuroT+ is a modular air handling unit that can be customised with cooling coils to meet the demands of larger-scale operations. It's the ultimate all-in-one climate solution offering integrated ventilation, heating, and cooling.
- Ideal for: Large commercial premises, distribution centres, and multi-zone facilities
- Key benefit: Scalable performance with optional upgrades as needs evolve
Sustainable Cooling for the Future
As energy prices fluctuate and sustainability targets tighten, Reznor’s technologies are designed to meet both current performance standards and future environmental goals.
- Electric and Gas-Free Options: E+ and LIRA help reduce reliance on fossil fuels and support net-zero strategies.
- Smart Grid Compatibility: Ready for integration into intelligent building management systems.
- Lower Emissions, Higher Efficiency: Reznor’s cooling solutions help cut carbon while delivering dependable comfort.
Incorporating Reznor’s cooling technology ensures better working conditions, helps businesses demonstrate ESG compliance, and reduces long-term energy expenditures.
