CASE STUDY ALDI COLD STORAGE
SUPPORTING REGULATION Cold storage operators carry overlapping legal duties across food safety, workplace health & safety and energy efficiency. Climate separation supports compliance on every front.
Aldi experienced condensation plumes entering a freezer space, creating temperature fluctuations that threatened operational efficiency and food safety. The freezer entrance, a substantial 3 m × 3 m opening between chilled and freezer environments, created a large interface for warm-air and moisture ingress. Key priorities were minimising warm-air infiltration and moisture ingress, maintaining stable freezer temperatures, and reducing the risk of surface icing.
Requirement
What It Means
How Biddle Helps
Food Safety Act 1990 & Food Safety (England) Regs 2013 (retained Reg EC 852/2004
Chilled food ≤ 8°C; frozen food −18°C or colder, under HACCP monitoring Cold storage is a defined CCP; temperature must be controlled & recorded
Stable separation helps hold critical temperature limits and prevent drift Reduces infiltration-driven fluctuations that cause excursions
SOLUTION
Following an extensive site survey, Biddle supplied the IndAC2 air curtain, capable of protecting openings up to 6m high.
HACCP critical control points
Employers must control slip, ice and cold-exposure hazards
Reduces floor icing, fog and wet surfaces around doorways
HSE workplace duties
Side shields were fitted on both sides to minimise lateral infiltration and improve containment, alongside a customised software configuration set freezer-specific temperature setpoints and bespoke overrun times.
Lower refrigeration demand, fewer defrost cycles, less plant wear
Energy & sustainability (e.g. ESOS / net-zero goals)
Pressure to cut refrigeration energy & emissions
Note: Biddle products support compliance by stabilising the storage environment; they are not a substitute for a complete food-safety management or refrigeration system. Specific duties vary by nation (England, Scotland, Wales, Northern Ireland) and application.
CONCLUSION During commissioning, thermal imaging clearly showed the IndAC2 creating a barrier that prevented heat transfer across the threshold; holding the freezer at −18.2°C against −3.0°C in the adjacent chiller room. The installation delivered elimination of visible condensation plumes, improved energy efficiency through reduced cold-air loss, enhanced staff safety around the entrance, and maintained storage temperatures for food quality and compliance.
