Thermal craftmanship across national borders

The Polish branch of our customer entrusted Callens with the heating of its 60 m3 chemical storage tank and, subsequently, of the filler and circulation pipes toward the mixing machine.

Heated transport from A to B – part 2

The first batch of our customer’s transportation containers has been receiving heat from Callens for a few years now. It allows the company to transport temperature-sensitive goods safely. During the second phase of the project we scaled up the entire installation to provide more heat and more efficiency all together.

Solution to a special heat demand

This system at a leading producer of oleochemicals consists of a gas-fuelled thermal oil system with peripherals in a brand-new boiler room.

Heat grid for more sustainable energy consumption

Callens system puts the residual heat generated by this client to sustainable use! A thermal oil and central heating circuit now feeds into the city’s new heat grid.

Steam boiler from our rental range ensures grain processing night and day

Where grain processing requires steam around the clock, also the backup steam boiler must be in good nick. With that in mind, we replaced the pre-existing system while a new full option steam boiler from our rental range provided the backup our client needed.

60-ton steam boiler breaks the record

This 60-ton boiler sets a Callens record, for it is the largest steam boiler we ever installed. Together with a tri-pass 40-ton steam boiler, it will spend its life heating the many rollers of a paper mill.
