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.

Wanted: compact steam boiler system

The compact boiler room of this particular client required a compact steam boiler system. The Callens crew took up the challenge, got down to work in our workshop and delivered a Jumag steam generator on skid, complete with all the peripherals.

Central heating boilers heat gas pressure regulating station

These Belgian gas pressure regulating stations are supplied with Callens heat to prevent clumps of ice forming in the pipelines. Now the gas can be depressurised in all safety before it makes its way to the homes in the area.

Central heating boiler rides the waves of a wood drying plant’s fluctuating heat demands
