Substrate: Shell Heat Exchanger
Problem: CUI, Personnel Protection
Reason for app: Ease of main.,
personnel protection
Starting Temp = 200°F (93°C)
Post app. Temp = 100°F (37°C)
DFT = 40-60 mils (1.0-1.5mm)
This unit had a process temperature
requirements starting at 200F and tapering to 100 F. The coating allowed the facility to save costs of total insulation as the application could be tailor-sprayed to temperature requirements. The use of DTI brought the goal of Personnel Protection well with their limits and eliminated CUI.

| Example: Diffuser |
|
Substrate: Diffuser (sugar mill)
Problem: CUI, Personnel
Protection, heat retention
Reason for app: Needed to keep
diffuser at steady temp and
protect personnel from burns
Starting Temp = 190°F (87°C)
Post app. Temp = 110°F (43°C)
DFT = 60 mils
This sugar mill diffuser was not cost effective to conventionally insulate. The coating was selected due to its rapid application as well as total service ability. Post application all of its sugar mill process was well within the design parameters and allowed the facility to save tremendous dollars on energy.

| Tank Top |

Substrate: Halterman Tank Storage Facility
Problem: Tanks were imploding due to pressure differentials while cleaning
Reason for app: Stop implosion, control radiant heat transfer
Starting Temp = 300°F+ (148°C) Steam
Result: NO IMPLOSIONS
DFT = 30 mils (0.75mm)
This unique application was a problem of internal pressure implosions caused by flash cooling in a rain shower. Due to these implosions approx $1,000,000.00 worth of tank damage was caused each year. The coating was applied to the top of the tanks only to help mitigate the temperature differentials during the flash cooling showers. After application, no longer were there any tank implosions. This resulted in a full scale project to include the remaining 38 tanks in the facility.

Starting Temp = 200°F (93°C)
Post app. Temp = 125°F (51°C)
DFT = 60 mils (1.5mm)
Valves are an excellent application are with DTI. Their complicated geometry usually results in high fabrication costs and non inspect ability without removing the traditional insulation.

Project: High Sierra Asphalt tank roof
Location: Ft Lauderdale, FL
Reason for application: energy
retention/maintain 350°F (176°C)
Results: estimated 50% energy retention.
Tank tops are a perfect fit with the coating as typically most are left un-insulated due to CUI development as well as potential other hazards. DTI has been used in many cases to recapture lost energy and help maintain tighter tolerance on temperatures within the tank. This results in less heating costs as well as being easier on the heating equipment.

Project: Valero crude oil storage
Location: St. Charles, LA
Vessel name: 150-4, 150-5, 150-6
Reason for application: energy retention, CUI
(CUI so bad that when the inspector drilled
through insulation the drill went through the
sidewall of the tank).
This application was unique in the mater of being a tank affected by hurricane Katrina & Rita. The damage was caused by flying debris which broke the integrity of the standard tank insulation. With the coating applied the facility was running again in a short matter of time and produced the same insulation qualities as its standard 2” batt system. Now the tank is no longer susceptible to the corrosion under insulation (CUI) it had in the pre- application photos. The facility manager was pleased also with the full inspect ability of the unit as well.

Project: Mobile Tool Unit
Vessel name: Air Compressor Box
Reason for application: Reduce
Radiant heat gain and keep equipment to temperature during cold weather.
This unit was designed to take standard 20’ containers and use them as equipment skids that could be remotely used in various areas of the world. The coating was applied to many places of this unit to include hot equipment and the side walls.

| Satelite Container |
|
Project: Boeing Satellite Container
Location: Washington State
Reason for application: CUI, Personnel protection, Cost
The coating was selected for this application
as traditional insulation created CUI
beyond its control. The coating offered the
owner full inspect ability and kept internal
temperatures well within parameters.
