Energy recovery is indispensable in any steam, thermal oil, central heating and air technology system and comes in a myriad of forms. We create the right combination, tailored to your application, to usefully repurpose as much energy as possible and keep your energy consumption under control.
Do you have a temporary need for extra thermal capacity? Rent a steam boiler, thermal oil boiler or an industrial heating boiler. At Callens you can find an extensive range of premium rental boilers for your production area, with capacities going from 200 kg to 25 tons.
Our customers reap the benefits of a unified Callens group. We packaged steam production, odor combustion, ventilation and the entire balance of plant in one smart package to relieve Aviko of all its worries in its brand-new factory in Poperinge.
From old to new, to future-proof: this chemical giant moved its old steam installation aside for a new one, which includes a 'dual fuel' burner. In addition, we offered some extras that make the steam supply even more cost-effective.
Our customer, Vynova (located in Tessenderlo), produces basic chemicals for a wide range of industries. During the process, hydrogen is created, as a byproduct, which we then use as a renewable energy source for the production of steam on the plant.
Liquid and semi-liquid substances need reliable heat to be transported safely. With our steam and central heating system, we heat bulk containers containing such substances and keep them at the right temperature.
Thanks to our extra steam collector and pipelines, this manufacturer of canned drinks can now usefully deploy all the steam available on his site, feeding an extra production line of well-known fruit juices.
