FREECOOL®

Energy-Efficient Climate Control Using What You Already Have.

Traditional DX cooling systems are energy-intensive, expensive to operate, and often overkill for applications where waste heat or ambient conditions could do the heavy lifting. Yet most facilities default to conventional refrigeration because it's familiar, not because it's smart.

FREECOOL® changes the economics of climate control.
These advanced air handling units utilize your facility's available waste energy sources to condition indoor spaces with the smallest possible energy footprint. Whether you're cooling warehouses, retail spaces, or production environments, FREECOOL® delivers the climate conditions you need while dramatically reducing operational costs and improving indoor air quality.

Solutions

From air handling to energy recovery, our engineered systems reduce costs, improve productivity, and create long-term sustainability.

Solutions for Every Climate Challenge

At SCE®, we don't just supply equipment—we engineer complete climate control systems tailored to your specific challenges. Every solution integrates our patented technologies, proven methodologies, and global partnerships to deliver measurable improvements in efficiency, productivity, and sustainability.

The Energy Waste Problem

Most facilities generate waste heat from processes, equipment, or adjacent operations. Meanwhile, they're running energy-intensive cooling systems to maintain comfortable or controlled environments. The waste heat gets vented. The cooling systems consume electricity. And nobody questions whether there's a better way.

FREECOOL® captures what you're throwing away and puts it to work.

How It Works:

Adiabatic Air Manipulation

FREECOOL® systems use adiabatic cooling principles, evaporative processes that cool or condition air using minimal energy compared to traditional refrigeration. By harnessing waste heat sources available in your facility, these air handling units can provide:

  • Direct and indirect evaporative cooling for efficient temperature reduction
  • Hybrid heating and cooling that adapts to seasonal and operational demands
  • Energy recovery that repurposes waste energy rather than consuming grid power
  • The approach is fundamentally different from DX systems: instead of forcing climate control through energy-intensive refrigeration, FREECOOL® works with natural thermodynamic processes and available energy sources.

Real-World Applications and Benefits

FREECOOL® systems deliver measurable advantages across multiple environments:

Retail & Distribution: Replace traditional DX cooling systems in warehouses and retail floors with FREECOOL® adiabatic AHUs. Maintain specified internal climate conditions while reducing operational costs and improving indoor air quality through better ventilation and air circulation.

Production & Processing: Control climate in manufacturing environments, food production facilities, and processing areas where maintaining specific temperature and humidity ranges is critical for product quality and worker comfort.

HVAC Optimisation: Upgrade existing HVAC infrastructure in enclosed spaces to improve comfort, health, and productivity while cutting energy consumption. FREECOOL® systems excel in applications where traditional HVAC is oversized or inefficient.

When you install FREECOOL®, the improvements are immediate:

Dramatically reduced energy consumption compared to conventional DX cooling systems
Lower operational costs by utilising waste heat and natural cooling processes
Improved indoor air quality through enhanced ventilation and air circulation
Maintained climate specifications without the energy penalty of traditional refrigeration
Reduced carbon footprint through energy-efficient operation
Simplified maintenance with fewer mechanical refrigeration components to service

FREECOOL® Systems are Engineered to Maximise Energy Recovery and Minimise Power Consumption

Available waste heat sources and ambient conditions
Target temperature and humidity requirements
Space volume and air exchange needs
Operational patterns and seasonal variations

The Business Case for Smarter Climate Control

Energy costs represent a significant ongoing operational expense. FREECOOL® attacks this expense at the source by:

  • Reducing or eliminating energy-intensive DX cooling requirements
  • Repurposing waste energy that's currently being vented
  • Lowering peak demand charges through reduced electrical load
  • Extending equipment lifespan through simplified mechanical systems
  • Improving worker productivity through better indoor air quality

The capital investment in FREECOOL® delivers ongoing returns through reduced energy bills, lower maintenance costs, and improved operational efficiency.
