Natural Refrigerants
NH₃ (ammonia) — zero GWP, highest industrial COP. CO₂ (R744) — GWP of 1, compact and efficient at low temperatures. Both avoid F-gas phase-down costs and regulatory risk. NH₃/CO₂ cascade systems deployed globally.
Sustainability
Natural refrigerants. Energy-efficient design. Reduced carbon footprint across the cold chain. Square Technology's approach to environmentally responsible industrial freezing and cooling.
Environmental Commitment
Built for a Low-Carbon Cold Chain
Industrial freezing is energy-intensive. Square Technology addresses this at system design level — refrigerant choice, heat recovery, insulation, and efficiency. Every percentage point gain compounds over 20+ year operating life.
Energy Efficiency
System COP impacts both operating cost and carbon footprint. Evaporator coil design, fin spacing, defrost strategy, airflow uniformity, and compressor selection all optimized to maximize kW cooling per kW electricity.
PIR Insulation Technology
Three German Hennecke fully automatic PIR panel lines. PIR offers superior thermal resistance per mm vs traditional PUR, reducing refrigeration load and long-term energy consumption for cold rooms and freezers.
Heat Recovery
Refrigeration systems reject large amounts of heat. Square Technology designs capture waste heat for facility heating, hot water, or process pre-heating — reducing total site energy consumption.
Equipment Longevity
Most sustainable equipment lasts. In-house manufacturing and quality control — from raw steel to finished system — ensures system lifetimes measured in decades. Fewer replacements = less embedded carbon.
GWP-Compliant Portfolio
Full product range designed for EU F-gas and global refrigerant phase-down compliance. Customers investing today are protected against future regulatory changes. Technical documentation supports environmental permitting.
