Problems
can be avoided by the selection of optimum processes for the treatment
of water for the fresh water supply and boiler supply water. The basis
for the correct design of such systems is specified by standards and
guidelines such as VDI 2035 and the specifications of the VdTÜV and TRD. In
combination with water analyses, the boiler data and the operating
conditions or water samples and the local conditions on site, JUDO
produces computer-assisted designs, backed up by expert advice and
comprehensive quotations, ensuring that your boiler systems function
perfectly.
JUDO offers you more: Free water analyses + computer-assisted design + selection of the optimum processes + comprehensive quotations and advice + ongoing consultation on site + commissioning and maintenance by our nationwide customer service network = customer care that creates confidence
Data and analysis values for computer-assisted design
Warm water boilers up to 100 °C supply temperature
» Total boiler output (kW) » Heating capacity (m³) » Supply temperature (°C) » Carbonate hardness or acid capacity KS 4,3 (°dH/mmol/l)
Hot water boilers over 100 °C supply temperature
» Total boiler output (kW) » Heating capacity (m³) » Supply temperature (°C) » Complete water analysis (see following table) » Low-salt or high-salt operation
Steam generators
» Total boiler output (kW) » Steam quantity (kg) » Steam pressure (bar) » Condensate return (%) » Complete water analysis (see following table)
