70kW Blast Chiller

Absolute Zero Refrigeration designed, manufactured, and installed this purpose-built blast chiller to meet the client’s specific production requirements. Engineered for high-performance chilling, the system rapidly cools pies from 70°C to 4°C within one hour, ensuring food safety, product consistency, and compliance with industry standards.

At the core of the system is a precision-controlled PLC that intelligently manages operation and energy efficiency. The design incorporates a variable-speed compressor and electronic expansion valves, delivering responsive control, reduced energy consumption, and reliable long-term performance.

To ensure uniform cooling across every batch, we custom-built booster fans, plenums, and air vanes that direct airflow evenly through the pies. Every component was carefully selected and integrated to provide robust functionality, consistent results, and lasting operational efficiency.
