Chilled Water Pipe Vibration Isolators - Vibration isolators protect the chilled water piping from receiving vibrations transmitted through the piping when the chillers are running. The vibrations can create problems not only for the chilled water piping but also for the building’s structure. The vibration isolators reduce or eliminate the vibrations that can be transmitted by the chillers. (more…)
Outside All Weather Boiler - Outside all-weather boilers are used in circumstances where it is not possible to install the boiler inside a mechanical room or anywhere in the building. There some considerations one needs to take into account about having an outdoor boiler especially if it is for a residential application. (more…)
HVACR Pipe Soldering Brazing - In HVACR there are two major types of soldering done. Soft Soldering for soldering water pipes and brazing or silver soldering for soldering refrigeration piping. There are various techniques for both types of soldering and everyone develops their own in the field but it is important to follow the basics of soldering when joining the piping together. Following the basics of soldering will ensure success and we all enjoy a successful job completed.
As always safety is first with anything. Two big considerations must be adhered to when soldering or brazing:
Wire Type and Sizing Considerations - When a professional electrician looks at a job to wire a house or a new circuit in any structure the primary consideration in the wiring job is the size and type of wire to be used for the job per the NEC. The same for a plumber when looking at a job the plumber will size the pipes based on the number of gallons needed to carry the proper amount of water to its destination. If the pipe is too small then the water needed will not reach its destination. This is almost the same for electrical wire except under-sizing electrical wire is dangerous. (more…)
