DryZONE-PLUS®

Heavy-Duty Freezer Protection for Non-Stop Operations

When your freezer doorway never really closes, when forklifts are constantly moving in and out, when goods flow 24/7, when strip curtains are more of a nuisance than a solution, you need protection that works without barriers.

DryZONE-PLUS® is engineered for exactly this. This advanced freezer protection system creates a self-contained air management tunnel that maintains dry air, prevents moisture ingress, eliminates thermal loss, and does it all with a permanently open doorway. No strip curtains. No high-speed doors. No compromises.

Solutions

From air handling to energy recovery, our engineered systems reduce costs, improve productivity, and create long-term sustainability.

Solutions for Every Climate Challenge

At SCE®, we don't just supply equipment—we engineer complete climate control systems tailored to your specific challenges. Every solution integrates our patented technologies, proven methodologies, and global partnerships to deliver measurable improvements in efficiency, productivity, and sustainability.

The High-Traffic Reality

In busy cold logistics operations, doorways are in constant use. Strip curtains get pushed aside, damaged, or removed entirely because they slow operations. High-speed doors create safety risks and maintenance headaches. Meanwhile, warm humid air floods in, ice accumulates, refrigeration plants strain under the load, and energy costs spiral.

Traditional solutions weren't designed for non-stop traffic. DryZONE-PLUS® was.

How It Works:

The Air Management Tunnel

DryZONE-PLUS® creates a protected corridor between climate zones using a self-contained tunnel structure filled with controlled dry air. Unlike simple air curtains or basic airlocks, this system actively manages the air environment within the tunnel, preventing both moisture transfer and thermal loss through the doorway. Workers and forklifts move through freely. Air doesn't.

The tunnel maintains consistent dry air conditions regardless of traffic volume, creating an effective barrier that:

  • Stops buoyancy flow (the natural movement of cold air down and out, warm air up and in)
  • Prevents moisture from travelling between zones
  • Eliminates the need for strip curtains or physical barriers
  • Keeps the doorway fully open and accessible for continuous traffic

 

Performance Where It Counts

In high-traffic cold storage and logistics facilities, DryZONE-PLUS® delivers measurable operational improvements:

  • Eliminates ice and moisture buildup at freezer entrances, even with doors permanently open
  • Prevents thermal loss by breaking the buoyancy effect that drives air exchange between zones
  • Removes strip curtain costs and problems entirely, no more damaged, frozen, or missing curtains
  • Improves safety by maintaining dry, ice-free floors at high-traffic access points
  • Reduces refrigeration plant load by preventing warm air infiltration and moisture ingress
  • Ensures HACCP and OHS compliance through consistent moisture control and safe access
  • Increases operational efficiency by eliminating physical barriers that slow workflow
  • Cuts energy consumption by protecting the freezer environment without compromising access

DryZONE-PLUS® is built to handle the toughest conditions in cold logistics:

Permanently open doorways with continuous forklift and pedestrian traffic
Temperature transitions from ambient to chilled (2-10°C) or ambient to freezer (-25°C and below)
High-volume operations where throughput can't be compromised by doors or barriers
24/7 facilities that need protection around the clock without operational interruption

DryZONE-PLUS® works even more effectively when integrated with complementary SCE® technologies:

Combine with DryJET-THERMAL®

Combine with DryJET-THERMAL® for comprehensive moisture and thermal protection. The air management tunnel handles moisture control while DryJET-THERMAL® creates an additional thermal barrier, delivering up to 95% reduction in buoyancy-driven airflow.

Add DryJET® Ceiling Diffusers

Add DryJET® ceiling diffusers to eliminate condensation in adjoining dispatch or receiving areas, creating a completely dry environment from floor to ceiling. At SCE®, we design integrated solutions, not isolated products. When your operation demands maximum protection, we engineer systems that work together seamlessly.
