Attention HMA Plant Operators

Reduce energy cost by 68% with Cool-SkinTM insulation sleeve on hot oil “jumper” hoses.

A typical Hot Mix Asphalt (HMA) plants makes use of hundreds of feet of flexible metal “jumper” hoses to transfer hot oil across connection flanges. These hoses are frequently overlooked by insulation contractors as they usually have a tight bend radius and they are difficult to protect.  In addition the neglected jumper hoses are often considered unimportant because they represent a small portion of the hot oil system.  The reality is that these un-insulated lines result in huge inefficiencies and cost thousands of dollars in wasted energy.  This would is similar to leaving a window open all winter long.  It just doesn’t make good sense.

Worbo has developed an effective thermal insulation solution that enables HMA plants to recover significant heat losses on small diameter and tight radius hoses with ease.  Introducing Cool-SkinTM sleeve!

Unlike traditional methods such as mineral wool and hard aluminum cladding, Cool-SkinTM is easy to install and does not require expensive insulation contractors.   A hook and loop self gripping fastener is incorporated into its design allowing operations staff efficient access to process lines while performing maintenance procedures or trouble-shooting system components.  Once line interruption is complete, Cool-Skin™ is simply re-installed in a few short seconds. 

An additional important and impressive benefit to the Cool-SkinTM technology is that it incorporates a closed cell insulating structure that will not absorb water or moisture making it an effective insulator even in wet conditions.

Ongoing field monitoring has proven that insulating a flexible metal hose (1 ½” OD) with Worbo’s Cool-Skin™ sleeve at a typical HMA plants will reduce heating cost an average of $30 for every foot of jumper hose in just one short seven (7) month operating season.  In most cases Cool-Skin™ pays for itself within the first four (4) months of installation.

Cool-Skin Elbows and Tee’s

In response to a growing demand from our customers, Worbo is excited to announce the release of a new product line of easy to install elbow and tee insulation sleeves for high temperature applications.   Introducing Cool-Skin elbows and tee sleeves by Worbo.

These products offer a fantastic complement to our extremely popular line of Cool-SkinTM sleeves.  They are a perfect solution for insulating hoses and process lines that contain a tight bend radius or for lines that have tee intersections.   Traditionally it has been a challenge for plant engineers and insulation contractors to provide a satisfactory and effective thermal barrier in these areas.  Worbo’s wonderfully simple solution enables our customers to quickly and easily install these removable Cool-SkinTM  insulation components around elbows (from 45’s to 90’s) and at tee junctions.   They offer a very precise fit around a wide variety of diameters to maximize insulation coverage to minimize heat loss and to prevent burn injuries at these tricky locations.

Cool-SkinTM elbows and tees are fabricated from the same tried and tested materials that make up our existing Cool-SkinTM sleeve products.  They are equipped with a durable abrasion resistant jacketing system that encapsulates a clean non-fibrous insulation medium exhibiting an extremely low thermal conductivity to provide a very efficient thermal barrier.  As with many of our Cool-SkinTM products our elbows and tees are supplied with a hook and loop closure for easy installation and removal. 

For applications where radiant heat is a concern our Eko-ThermTM jacketing system may be supplied as an alternative to the standard yellow jacket.  The combination of our shiny aluminized Eko-ThermTM material coupled with our non-fibrous insulation medium offers an effective barrier from conductive heat sources as well as from radiant heat sources.   Up to 90% of radiant heat will be reflected away from the low emissivity and shiny surface of the insulation component.  This doubly effective technology will ensure that the process temperatures can be accurately maintained with a minimal insulation wall thickness.
