With Rotho´s curing systems, one can speed up the curing process and will get the early strength of production in a short time.
Rotho is considered a world leader in the field of curing system and has established a strong presence in several global markets.
With head office and factory in Germany, the company has supplied more than 1,000 plants worldwide.
Concrete with high proportion of fly-ash needs more than 21 to 27 days to harden in natural curing. However, with the Rotho system, one can speed up the curing process and will get the early strength of production in a short time. The system consists of a curing chamber and an air-circulation system. It takes the heat from the hydration process of the product and starts circulating the air inside the closed chamber. It maintains a constant humidity and temperature with a sufficient air flow per hour.
Auto and semi-automatic
Rotho supplies curing systems for automatic and semi-automatic plants.
For automatic plants, the company has developed a big chamber concept, which is 100 per cent accepted by the market. The curing process is more effective than the conventional way, by making the curing chamber with blocks and closing the front by individual shutter doors.
For semi-automatic plants, depending on the pallet size, Rotho offers three different types of curing chambers:
1. The products will be transferred into the chambers by the help of a forklift. In this case, the pallet size should be more than 1,200 mm in length because the minimum width of a forklift available in India is 1,100 mm.
2. If the pallet size is more than 900 mm and less than 1,100 mm, a battery operated manual lifter will be offered which can help place the pallets in the galvanized racks of the curing chamber.
3. For pallet size less than 600 mm, a garage type system is available, which allows clients to place their pallets into local made iron racks and transfer these racks by forklift into the curing chambers.
All the above versions come along with an air circulation system in order to fasten up the curing process and improve the product quality.
For the Indian market
India has a huge market of concrete and fly-ash products and the demand for quality improvement combined with time reduction is growing from day to day. Since the commencement of its activities in India in 2010, Rotho has supplied curing solutions for six fully automatic block and paver plants. In 2015, the company supplied the first curing system for semi-automatic plant near Delhi. Until April 2016, two new orders have been finalised.
Further, Rotho will supply a fully automatic system (big chamber solution with air circulation) to a client in Mysore, who also bought a REIT block machine for its new plant. Its production start is planned for August 2016.
The second system will be supplied to a customer in Nepal, who decided to go with a Forest Press machine.
At Bauma 2016 in Munich, Rotho had launched the new ProCure system, a newly designed curing system, which will supply additional heat and steam into the curing chamber in order to allow a 365 days production process.
