In hydronic and water systems, the air precharge pressure of expansion vessels must be set according to both the building height and the system conditions. For example, a building with a height of 40 meters creates a static pressure of about 4.0 bar. The expansion vessel should be charged to a pressure close to this value before operation. A common problem in the field is that technicians often recharge the vessel without checking the required value. If the air pressure is set too low, the vessel will not absorb expansion water properly, leading to frequent safety valve discharges. If the pressure is set too high, water will not enter the vessel, resulting in unstable system operation. Setting the vessel to the right pressure may seem like a small detail, but it has a major impact on system safety, efficiency, and service life.

Thank you for the information
احببت أن أشارككم تجربتين مميزتين من زياراتي الأخيرة في المملكة العربية السعودية. الأولى كانت في مشروع البحر الأحمر، حيث تشرفت بالعمل مع الفريق المسؤول عن تشغيل غرفة غلايات جديدة. هناك، غلايتان حديثتان، كل واحدة بسعة 6 أطنان/ساعة، تعملان بوقود غاز البترول المسال (LPG) كان هدف الزيارة هو المساعدة في بدء التشغيل والتأكد من أن كل شيء يسير بالشكل المطلوب، وهي تجربة لا تُنسى. الزيارة الثانية كانت في المدينة المنورة، حيث قمنا بفحص أربع غلايات، سعة كل واحدة 2 طن/ساعة. كان التركيز على التأكد من سلامة وكفاءة أنظمة التشغيل. هذه النوعية من الزيارات مهمة جداً لضمان استمرارية العمل بأمان وموثوقية، وهي تذكير دائم بأهمية التفاصيل الدقيقة في مجالنا. كل زيارة ميدانية تضيف لي الكثير من الخبرة والمعرفة. أشعر بامتنان كبير لكل فرصة مع زملائي في هذا المجال. Iam happy to share a couple of unique experiences from my recent site visits in Saudi Arabia. First, I had the privilege of visiting a new site at the Red Sea Project to assist with the commissioning of a new boiler room. Consisting two new boilers, each 6 tons/hr, running on LPG burners. The goal of the visit was to help with the initial startup and make sure everything was running smoothly, and it was a truly memorable experience. My second visit was to Madinah, where we conducted an inspection of four boilers, each with a capacity of 2 tons/hr. The focus was on ensuring the safety and efficiency of the operating systems. This kind of visit is crucial for guaranteeing continued safe and reliable operation, and it's a constant reminder of how much the small details matter in our field. Every site visit adds to my experience and knowledge. I'm so grateful for every chance I work with my colleagues in this industry.
