Installed System Applications
Thermal Loss Prevention
DryJET-THERMAL® creates a powerful horizontal air stream that seals doorways, effectively stopping heat transfer.
Moisture Control
DryZONE® and DryZONE-PLUS® provide superior moisture protection with doors open 24/7 — no strip curtains required. When paired with DryJET-THERMAL®, the system offers a comprehensive barrier against both heat and moisture intrusion.
The images below show the DryJET-THERMAL® applied to the DryZONE-PLUS® tunnel to prevent the freezer from losing energy as well as from moisture gain. A comprehensive solution that allows the doorway to remain open 24 hours a day with full protection against moisture gain as well as heat loss.
Visual Example: DryJET-THERMAL® + DryZONE-PLUS® working together to keep a freezer dry and energy efficient with an always-open doorway.
DryJET® Ceiling Diffuser
South African Patent No: 2023/007746
Engineered Laminar Flow for Condensation-Free Ceilings
Uniform laminar airflow blankets ceiling surfaces
Prevents condensation by maintaining a consistent dry air layer
Ensures wider coverage with fewer ceiling penetrations
Reduces HVAC unit size due to more efficient air mixing
Protects ceiling structure via sandwich-construction penetration design
Adjustable air coverage control for varied flow rates
Key component of DrySPACE® — SCE’s cold-climate airflow solution
Made from stainless steel in 3CR-12 powder-coated or 304L brushed finish
How It Works: The Coanda Effect
The DryJET® Ceiling Diffuser utilizes the Coanda Effect, where cold, dry air flows tangentially across the ceiling at high velocity. This creates a low-pressure zone, ensuring the air adheres to the surface and entrains surrounding moisture-laden air — preventing ceiling condensation in cold environments.
Result: One diffuser covers more area with less infrastructure, saving cost and enhancing reliability.
Installed Ceiling Application Example
A horizontal film of dry air flows across the ceiling, maintaining dry, fog-free, condensation-resistant surfaces even in demanding cold processing spaces.
