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
Square Technology addresses this at the system-design level through refrigerant selection, heat recovery, insulation, and efficiency improvements. Every percentage-point gain compounds over an operating life of more than 20 years.
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 are deployed globally.
Evaporator coil design, fin spacing, defrost strategy, airflow uniformity, and compressor selection are all optimized to maximize kilowatts of cooling per kilowatt of electricity.
PIR offers greater thermal resistance per millimetre than traditional PUR, reducing the refrigeration load and long-term energy consumption of cold rooms and freezers.
Square Technology designs systems that capture waste heat for facility heating, hot water, or process preheating, thereby reducing total site energy consumption.
Most sustainable equipment lasts. In-house manufacturing and quality control — from raw steel to finished system — ensures system lifetimes measured in decades. Fewer replacements mean less embodied carbon.
The full product range is designed to comply with EU F-gas requirements and global refrigerant phase-down regulations. Customers investing today are protected against future regulatory changes. Technical documentation supports environmental permitting.
