FORCAS® Precision steel tube ideally suited for greenhouse heating systems We are Tata Steel Tata Steel is one of Europe’s leading steel producers, with steelmaking in the UK and in the Netherlands, and manufacturing plants across Europe. The company supplies high-quality strip steel products to demanding markets such as construction, automotive, packaging and engineering. We produce a wide range of welded steel tubes, including coated precision products. These tubes are produced at our dedicated site in Oosterhout in the Netherlands. Working in partnership We regard our customers as partners...

Forcas® Crop heating tubes PRECISE HEAT CONTROL TO MAXIMISE ENERGY EFFICIENCY The small tube diameter enables the heating system to be run on a minimum volume of water, this allows heat emission to be controlled very precisely to save costs and energy. Forcas® is a thin-walled (1.2mm) cropheating tube available in two diameters, 28mm and 35mm. The outside of the tube is thermally galvanised, in-line, as part of our manufacturing process, and then given an additional white flexible powder coating. This double protection makes Forcas® maintenance-friendly and ensures optimal light in the greenhouse....

APPLICATIONS It’s hardly surprising that Forcas® is finding its way into virtually every aspect of greenhouse cultivation. With this height-adjustable system, tubes are positioned near the growing tips of plants such as tomatoes and paprikas. In this way, Forcas® lowers humidity, which reduces the likelihood of diseases developing. The heating system is able to ‘grow’ with the plants. This increases product quality, produces a higher return per square metre and saves on heating costs. The versatile Forcas® system is also used in combination with tables on which various types of pot plants are...

Forcas Crop heating tubes TECHNICAL SPECIFICATIONS Heat emission Graph 1 Heat emission 1. ocation of the tubes - The location of the tubes in relation to L the crop affects the air circulation around the tube. If the tube is contained within a more or less closed crop, up to 15 % less heat will be emitted than if the tube is fully exposed. The location of the tubes does not affect the portion of heat emission transmitted by means of radiation. 2. he temperature difference - This is the temperature difference T between the greenhouse air and the average tube temperature (i.e. the average of supply...

Technical Specifications The main specifications for various tube sizes are shown in the summary table below. Main specifications Unit Diameter Wall thickness Weight - without water Weight - with water Water content Note: 3/4” and ø51 are competitor tubes The table below shows the theoretical maximum sag in the middle of a tube filled with water. The sag is shown for varying support intervals as a result of the tube’s own weight. Since lengthy spirals are used in practice, there will be upward pressures at the extremity of the tube. Therefore, the maximum sag shown below will not be achieved...
