Company Name: Witheld
Project: Heated stainless steel columns housing ammonia gas at 60?C
Coating used: Mascoat Industrial-DTI
Thickness: 60 mils (1.5 mm)
Reason for application: Personnel protection and energy retention
Energy savings: >50%
A research facility in New South Wales approached Mascoat to provide a solution to personnel protection and energy retention issues associated with their heated columns. The stainless steel cylindrical columns used to house ammonia gas were measured to have an internal and external surface temperature of over 140?F (60?C), which caused concerns for personnel protection as well as heat/energy loss issues.
Mascoat Specialists collaborated with the client to calculate temperature reductions and potential energy savings with a 60 mils (1.5 mm) application of Mascoat Industrial-DTI. Results detailed that, while the contents remained at 60?C, the coating would reduce bare skin temperatures of the external tanks to be less than 115?F (46?C.) Secondly, the heat loss of the columns without insulation was calculated at 6.3 kWh/hr. By applying the coating, the energy savings were in excess of 50%; with the heat loss being reduced down to 2.19 kWh/hr, the average savings was around 4.11 kWh/hr.
The client proceeded with the application recommendation and applied the coating externally to their cylindrical stainless steel heated columns. After application of the coatings, the client was able to observe that the calculated reduction of heat loss and increased personnel protection was in line with the analysis calculations. They have since reported that the coating has worked exactly as expected and plan to use it on further insulation projects.
