DuctSox Kwik-Thaw™ Sleeve for Freezers

Developed for freezers by DuctSox, the Kwik-Thaw Sleeve™ can be fitted to existing or new equipment operating with frosted coils. By collapsing when the unit goes into a heated defrost cycle, the sleeve keeps the heat inside the unit, speeding the thaw cycle time and reducing the amount of heat that would normally escape into the freezer.

Benefits:
• Helps coils thaw/quicker defrost cycle
• Reduces unintended product thawing in freezer
• Air porous fabric will not condensate during operation
• Adjustable outlet eases field adjustment for lower flow conditions

DuctSox Fabric Ducting installed at Wrigleys Facility

DuctSox Fabric Ducting at WrigleysDuctSox Fabric Ducting installed at Wrigleys Manufacturing & Distribution Facility – Asquith, NSW.

Wrigley is a recognised leader in confections with a wide range of product offerings including gum, mints, hard and chewy candies, and lollipops. Wrigley’s world-famous brands – including Extra®, Orbit®, Doublemint®, and 5™ chewing gums, as well as confectionery brands Skittles®, Starburst®, Altoids® and Life Savers®.

Recently completed using DuctSox Verona Fabric with 1-Row Aluminium U-Track Suspension System.

Critical selection criteria included comfort levels; zero risk of condensation; dust settling and hygiene.
• DuctSox Comfort-Flow linear L-Vent air distribution orifices were used to achieve high comfort levels.
• Verona fabric is a porous fabric (breathable) and will not condensate because of the airflow pattern around the fabric keeps the warm moist air off the fabric walls. This airflow will also avoid any dust settling on the fabric.
Wrigley's Asquith NSWDuctSox woven fabrics do not absorb moisture which can be a source for development of bacteria and mould. The hygienic nature of DuctSox provides resistance to fabric deterioration and breakdown extending life and minimising maintenance.
• All DuctSox systems are designed to be easily removed and laundered.

The installation needed to be aesthetically attractive as Wrigley receive visitors through the manufacturing plant. Using the DuctSox Alu U-Track system allowed the install to look more attractive without having tensioned cable extending past the fabric duct.

New Fabric Duct Design Manual

Fabric Duct Design Manual by DuctSoxDuctSox design manual

DuctSox have recently announced the release of their new fabric duct DuctSox Engineering and Design Manual. The revised manual follows the new methodology of designing a DuctSox System, beginning with selecting the Shape and Suspension/Retention system first. The manual also incorporates some of the newer DuctSox products and features, including SkeleCore and Nozzles.

This design manual should assist through the design process for all DuctSox® Fabric Duct Ventilation Systems. The process involves considerations that include layout, sizing, air dispersion, appearance, durability and installation.

The five steps of DuctSox system design:
• Series / Shape select shape for the application – Cylindrical or Surface Mount.
• Design Layout determine duct layout and sizing – selecting DuctSox location, diameter, lengths and required fittings.
• Fabric select fabric based on product quality, porosity, colors and/or required air dispersion type.
• Air Dispersion determine type, location and size of vents for Comfort Flow, orifices for High Throw or calculate required porosity for Low-Throw Series using to supplied airflow and static pressure.
• Suspension select Tension Cable, Suspended H-Track or Flush Mount Track for suspension.

There is some general information included on Critical Environments and Underfloor Air Distribution. For design assistance on these products, please contact your nearest ecoHVAC representative. For more information on DuctSox Fabric Duct visit www.ecohvac.com.au.

 

Restaurant Solves Challenges with KitchenSox

Mrs. Doubtfire Restaurant Solves Cooking Hood Draft Challenges with KitchenSox.

The Issues:
• Performance challenges from kitchen ventilation system.
• Smoke and food odors wafted into portions of the dining area raising complaints from patrons seated at tables near the kitchen.
• Drafts from the existing make-up air HVAC system were drawing smoke and grease and depositing them onto the diffuser, walls, ceilings, and other kitchen surfaces requiring annual maintenance costs.
• Drafts from the air conditioning supply over the food prep area was prematurely cooling prepared hot entrees and employees in other kitchen areas were uncomfortably hot.

The Solution:

DuctSox KitchenSoxDuctSox recommended a custom KitchenSox system to disperse the airflow uniformly, parallel and in front of the kitchen exhaust hood. The metal diffusers were replaced with two eight-foot-long (2.44m), 28-inch-diameter (711mm) D-shaped KitchenSox fabric diffusers. Instead of the metal diffuser’s estimated 500-fpm (2.54m/s) airflow that caused turbulence and disruption of the cooking hood’s capture, the air is gently and evenly dispersed through the fabric into the entire kitchen area at a significantly slower 85-fpm (0.43m/s) rate. Without the previous high velocity airflow and subsequent turbulence, the dual exhaust cooking hood now efficiently performs up to its design standards and captures smoke, grease particulates and cooking odors without overflow.

The End Result:

A happy customer. Chef Kevin Gin couldn’t be happier. “This is really a common problem (inadequate cooking hood drafting) I think many restaurants suffer from and don’t realize there’s a simple, inexpensive solution,” said Gin. “We once thought replacing the HVAC system would improve our kitchen ventilation challenges, but we now realize it probably wouldn’t have remedied what was actually a ventilation problem that fabric ductwork solved.”
