CERAMIC HEAT BARRIER COATINGS

A passive investment towards improved control over energy

costs

Underlying Problem

Controlling the temperature inside a building

Energy costs escalating Most existing buildings not energy

efficient Retro fitting can be costly Equipment replacement costly Must reduce energy consumption Maintenance influence energy

consumption

Solving the problem

More efficient equipment Introduction of renewable energy sources Improving insulation Reducing energy needed for heating and

cooling Applying energy management

Basic Principles

Many sources of heat: Equipment, people, sun

Heat moves towards cold Heat transfer via conduction, convection

and radiation Radiation is a major element

Reflection Emissivity

BASIC PRINCIPLES

Technology

Insulation materials Inverters, timers, friction reduction, direct

drives, etc. NASA development for space craft Nano technology Ceramic Heat Barrier Coatings

Product Composition

Effect

Reduction in radiated heat transfer From outside to inside when coated on

outsides From inside to outside when coated on insides

Reduction in conduction due to reduced radiation

Reduction in thermal stress for substrate Reduction in energy consumption to

regulate temperature

Typical Uses

Outside of walls and roof Inside of walls and ceiling Piping for steam Ducting for air conditioning Equipment heat shields Warehousing spaces Tanks and storage vessels Load boxes of vehicles

35 ⁰ Cambient temp.

Internal Heat Load

Reduction from 176 to

132 watts/sq.m

80% Reflectivity 20% Emissivity

Galvanised Steel Roof Sheeting0,5 mm thick

Coated with 500 µm wft CHBC

Benefits (1)

Reduces interior heat of buildings by up to 45%

Save electricity by using less air conditioning and refrigeration

Greater indoor comfort during hot weather Greater indoor comfort during cold weather Stops thermal ageing by reducing heat load Insulates roofs at a fraction of the cost

Benefits (2)

Prevents rust, eliminates blistering, peeling & cracking

Eco-friendly as it reduces dependence on electricity

Easy and quick low-cost application Insulates hot surfaces to provide improved

safety Is non toxic and therefore does not harm the

environment Is rust and mildew resistant Repels moisture

Benefits (3)

Easy to clean with soap and water Abrasion resistant Flame resistant Can be used on a wide variety of surfaces Long life without degradation Can be applied in tight spaces where

access is problematic Accidental blemishes can easily be

repaired

A passive investment

Cooling load reduction = lower energy costs Heat load reduction = lower energy costs Improved corrosion protection = lower

maintenance cost Reduced thermal stress = lower

maintenance cost Wear and fungus resistance = lower

maintenance cost Most payback periods less than 24 months Economic life of coating at least 10 years

Conclusion

It pays to install a Ceramic Heat Barrier Coating
