Classen Apparatebau Wiesloch GmbH: At a glance

CAW is a world-wide operating leading manufacturer and supplier

of highly customized industrial high temperature process heating

systems

Services range from pre-contractual engineering and feasibility

studies through single plant components and up to turn-key

energy centers

Technical and after sales support, plans for preventative and

regular maintenance, owners’ staff training, spare and wear parts

warehousing ensure a safe and reliable operation of CAW heating

systems

CAW has decades of vast knowledge and experience in the field of

industrial combustion engineering, high temperature heat

generation and transfer technology as well as decentralized power

generation (CHP) - “embedded power generation”

Thermal fluid heating systems

Thermal oil heating is an indirect heating in which a liquid phase

heat transfer medium (mineral-based or synthetic “thermal oil”) is

heated by a fluid heater and circulated by a pump within a closed

loop system over the heat consumer(s).

Comparison of thermal oil heating vs. steam heating in process

heating applications

Steam boiler plants Thermal oil / fluid heating systems

Steam pressure at 250 °C 39,7 bar Vapor pressure at 250 °C 0,016 bar

Water Treatment is needed to

minimize corrosion

Thermal fluid (organic heat

transfer oil) eliminates corrosion

problems

The open heating circuit causes a

loss of 10 … 20 %Closed system, no losses

Service life expectancy 15 – 20

years

Service life expectancy is 25+

years

High operating expenses Low operating expenses

Consequent systems design with a strong focus on industrial

applications

Basic features of all CAW-systems:

Fully customized systems design – built to purpose

Heavy-duty industrial design with high-end plant components

Operator-friendly and cost-efficient equipment with minimum

downtime for service and maintenance

Low maintenance requirements and maximum operational

availability

Compliance with all operational health and safety standards

Compliance with the applicable environmental protection

standards
