Thermal Barrier Systems

Patented DryJET-THERMAL® Technology Keeps Cold Storage Safe, Dry, and Efficient

Traditional plastic freezer curtains are inefficient, unsafe, and constantly need replacement. They slow operations, get damaged by forklifts, and still allow ice formation and thermal loss. SCE®'s patented thermal barrier systems create invisible air barriers that prevent cold wash, eliminate ice and condensation buildup, and stop thermal loss at cold storage entry points, without obstructing traffic or compromising safety.

From cold storage facilities and chilled logistics operations to meat processing plants and high-traffic freezer environments, our thermal barriers deliver measurable improvements in energy efficiency, safety, and operational reliability.

Featured Thermal Barrier Technologies

Our thermal barrier solutions provide comprehensive protection for cold storage environments, from entry point barriers to production optimisation systems.
DryJET-THERMAL®

Patented invisible air barrier that replaces plastic strip curtains, reducing ice, condensation, and thermal loss by up to 95%. Safer, more efficient, and longer-lasting than traditional freezer curtains.

DryZONE-PLUS®

Heavy-duty dry air barrier system for high-traffic freezer and cold storage doorways. Maintains permanently open doorways with comprehensive moisture and thermal protection.

DryTUNNEL®

Controlled air tunnel that maintains separation between chilled and ambient spaces, preventing condensation and moisture ingress without physical barriers or workflow disruption.

DryGYRO®

Protects blast freezers by preventing moisture ingress, reducing ice buildup, and improving freezing efficiency. Increases capacity by up to 30% while reducing defrost cycles.

Key Benefits

Engineered thermal barriers deliver measurable improvements across safety, efficiency, and operational costs:
Eliminates Ice & Condensation

Prevent ice formation on floors, doorways, and equipment. Stop condensation that creates slip hazards and contaminates product. Maintain dry, safe working conditions in high-traffic cold areas.

Protects People, Products
& Equipment

Remove the safety hazards of strip curtains and icy floors. Protect product quality by preventing moisture contamination. Extend equipment lifespan by eliminating ice damage to doors, seals, and mechanisms.

Improves Energy Efficiency

Reduce thermal loss by up to 95% at cold storage entry points. Lower refrigeration plant energy consumption by preventing warm air infiltration. Cut defrost cycle frequency and duration in freezer operations.

Why Thermal Barriers Matters

The Problem with Strip Curtains:

Plastic strip curtains were designed decades ago as a low-cost barrier solution. They tear, freeze, get pushed aside, and provide minimal actual protection. Workers struggle with them, forklifts damage them, and they still allow significant air exchange, ice formation, and energy loss. Meanwhile, facilities continuously replace damaged curtains and clean up ice.

SCE®'s thermal barrier approach eliminates these problems by:

  • Creating invisible air barriers that don't obstruct traffic or slow operations
  • Preventing ice formation through controlled dry air management
  • Stopping thermal loss more effectively than any physical barrier (up to 95% reduction)
  • Improving safety by eliminating torn curtains and icy floors
  • Reducing maintenance through durable, long-lasting systems
  • Cutting energy costs by dramatically reducing refrigeration loads

The result: safer operations, lower energy consumption, and eliminated strip curtain replacement costs—all while maintaining open, unobstructed doorways.

Applications

SCE® thermal barrier systems protect cold environments across industries where ice, condensation, and thermal loss create operational and safety challenges:
Cold Storage & Chilled Logistics

Protect dock-leveller areas, dispatch zones, and receiving bays where cold storage meets ambient conditions. Eliminate ice at high-traffic entry points while maintaining open access for continuous forklift movement.

Meat Processing & Abattoirs

Prevent ceiling condensation in processing rooms and packaging areas. Protect blast freezers and gyros from moisture ingress. Maintain HACCP compliance through controlled dry conditions.

High-Traffic Freezer Operations

Maintain thermal barriers at permanently open doorways in busy distribution centres and logistics facilities. Handle continuous traffic without compromising freezer protection or energy efficiency.

Food Production & Packaging

Control moisture at transitions between temperature zones. Protect product quality in packaging areas adjacent to cold rooms. Prevent condensation on equipment and ceilings.

Pharmaceutical Cold Storage

Maintain validated temperature conditions while allowing necessary access. Prevent moisture that affects product stability and packaging integrity in controlled storage environments.

Retail Cold Rooms

Protect walk-in coolers and freezers in supermarkets and food service operations. Reduce energy costs while improving safety for staff accessing refrigerated storage.

How Thermal Barriers Works

Breaking the Buoyancy Effect

When cold and warm air meet at a doorway, physics drives air exchange: cold air sinks out while warm air rises in. This buoyancy effect causes constant thermal loss and moisture ingress. DryJET-THERMAL® creates a horizontal air stream that disrupts this natural flow, preventing air exchange without blocking the doorway.

Dry Air Management

DryZONE® and DryZONE-PLUS® systems create pressurised zones of dry air that prevent moisture from entering cold spaces. By controlling humidity at the entry point, ice formation is eliminated before it starts—keeping floors, walls, and equipment dry and safe.

Production Protection

DryGYRO® and DryTUNNEL® extend thermal barrier principles to specific production applications. DryGYRO® prevents moisture from entering blast freezers, allowing faster freezing with less ice accumulation. DryTUNNEL® maintains air separation through transition zones without physical barriers.

Strip Curtains vs. SCE® Thermal Barriers

Strip Curtains:
  • Physical obstruction slowing traffic
  • Constant damage requiring replacement
  • Limited thermal protection (30-50% at best)
  • Ice formation at doorways
  • Safety hazards (torn curtains, icy floors)
  • Ongoing replacement costs
SCE® Thermal Barriers
  • Invisible air barriers, no obstruction
  • Durable systems with minimal maintenance
  • Up to 95% thermal loss reduction
  • Eliminates ice and condensation
  • Improved safety (dry floors, clear access)
  • Long-term investment with ongoing savings
