How DryGYRO® unlocks hidden capacity in the fast freezers you already own.

Your gyro freezer, carton freezer, or blast freezer was engineered for a specific capacity. Then your operation grew. And now you’re pushing equipment beyond its limits, managing more ice, more defrost cycles, more downtime, and higher energy bills.

The frustrating part? The problem isn’t your equipment. It’s moisture.

While your product enters and exits your freezer, moisture is drawn in at the entrance and/or exit feed of the conveyor at the hole in the wall. That moisture turns to ice on coils, reducing heat transfer efficiency. Ice triggers more frequent defrost cycles. Defrost cycles mean the line stops. And every time the line stops, you lose production capacity you can’t get back.

DryGYRO® breaks this cycle by stopping moisture before it ever enters your freezer.

What is DryGYRO®?

DryGYRO® is a patented, retrofittable moisture control system designed specifically for gyro, carton, and blast freezers. It creates a protective envelope of dry air at the freezer entry point using a specialised entrance canopy and airlock, preventing moisture ingress before product enters the freezer.

The result: coils stay cleaner, freezing happens faster, and production runs longer between defrost cycles. No new equipment required. No major operational disruption. Just significantly better performance from the equipment you already have.

The real cost of ice buildup

In fast-freezing environments, ice is more than a maintenance issue, it’s a production bottleneck. Here’s what’s actually happening when moisture enters your freezer unchecked:

• Ice accumulates on coils, creating a thermal barrier that reduces heat transfer efficiency
• Reduced efficiency forces your refrigeration plant to work harder, consuming more energy
• More ice means more frequent defrost cycles  and each defrost cycle is production time lost
• Wet product (not frozen) issues emerge when equipment is pushed against or beyond design capacity
• Entrance and exit conveyor belts ice up, leading to linkage breaks and unplanned maintenance
• Condensation builds in injection and discharge halls, creating safety risks and hygiene concerns

Most operations accept this pattern as an unavoidable reality of fast freezing. It isn’t.

How DryGYRO® works

The system centres on a custom-engineered entrance/exit canopy and airlock that wraps the freezer entry/exit in controlled dry air. External moisture is stopped at the threshold   before it can reach coils, conveyors, or the freezer interior.

Integrated PLC controls with a touch screen HMI panel allow operators to switch between normal Production MODE™ and the system’s standout feature: DefrostMODE®.

DefrostMODE®: less downtime, faster restart

During defrost cycles, DefrostMODE® uses forced dry air to dramatically reduce defrost time. It heats up the interior fast with energy neutral warm dry air to allow fast defrost and then dries the interior after wash-down, ensuring no water freezes on coils at start-up. Conveyor belts are dried before production resumes, extending belt life and preventing linkage breaks.

The practical impact: shorter defrosts, clean and dry coils on restart, faster recovery after cleaning and longer production runs. Every defrost cycle becomes a smaller interruption   not a production event.

Clean, dry coils on start-up. Longer running times. Maximum heat transfer from the first product through the freezer.

 What this means for your operation

When DryGYRO® is retrofitted onto your existing equipment, the improvements are measurable and compounding:

• Up to 30% increase in freezer capacity  without capital investment in new equipment
• Fewer defrost cycles per 24-hour cycle, extending available production hours
• Reduced energy consumption per kilogram of frozen product through improved heat transfer
• Elimination of wet-product (not frozen) problems when operating at or near design capacity
• Dry, ice-free entrance and exit conveyor belts and gearboxes
• Reduced condensation and fog in injection and discharge halls
• Extended belt life and fewer conveyor linkage breaks
• Proximity sensors for gyro and carton freezers no longer have faults associated with the presence of ice
• Defrosts are faster allowing more production time and packed product.
• Simplified maintenance with dry, ice-free equipment

The combination of energy savings and capacity gains delivers a return on investment typically measured in months, not years.
