The operating temperature is reached more quickly after breaks or on the following day, which significantly reduces energy consumption - a clear advantage over gas boilers with higher heat losses.<\/li>\n<li><strong>Precise temperature control with modern sensor technology<\/strong><br \/>\nSophisticated sensors enable precise temperature measurement - crucial for sensitive, polymer-modified bitumen. The temperature curve can be documented as an effective means of quality assurance and process optimisation. In addition, the hysteresis can be set individually to avoid unnecessary temperature fluctuations, making the heating process even more efficient.<\/li>\n<li><strong>Maximum safety without open flames<\/strong><br \/>\nThe all-electric operation makes the E\u00a0MR\u00a0229 ideal for city centres, industrial facilities or enclosed spaces where gas appliances are not permitted. This increases safety and considerably expands the range of applications.<\/li>\n<li><strong>Optional functions<\/strong><br \/>\n- Customised special functions can be integrated via remote maintenance or during service<br \/>\n- Remote control via web browser in combination with optional modem<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Efficient, precise and safe.<\/p>\n<p>The E\u00a0MR\u00a0229 is a modern, electrically powered bitumen boiler, developed for demanding applications such as polymer-modified bitumen or places where open flames are not permitted.
