Changing from R-22 to R-410A or some other refrigerant, means you need to change your cooling coil. As of 2010, R-22 (often referred to as Freon®) was discontinued for use in new air conditioning systems. Because R-410A can absorb and release more heat than R-22, newer air conditioning compressors can run cooler, reducing the risk […]

Noise created during steam recirculation noise can not only be annoying, but cause damage to steam systems. So what causes recirculation noise in a steam system? 1.High differential pressure across orifice 2.Insufficient back pressure downstream 3.Improper sizing of baffle  4.Orifices discharging into tank below water line 5.Too much back pressure cause by globe value And […]

Control valve selection and installation is a vital process that can have a profound effect on the effectiveness of a fluid system. Specifically, process conditions and how they impact the selection process are important to understand. To help identify some of the key factors and process conditions that affect the decision, DFT Valves has created […]

With recent government announcements of tariff hikes on steel and aluminum imports, the impact on the steam, air, and water industry is expected to be significant. Raw materials like steel and aluminum typically account for over 50% of costs associated with process equipment. With tariffs on imports increasing by 25%, we encourage our customers to […]

The purpose of the burner is to mix molecules of fuel with molecules of air. A boiler will run only as well as the burner performs. A poorly designed boiler with an efficient burner may perform better than a well-designed boiler with a poor burner. Burners are designed to maximize combustion efficiency while minimizing the […]

Condensate carryover happens when dehumidification takes place on chilled water or DX coils. Typically drain pans are placed under air cooling coils to take care of any water that is generated when cooling air below its dew point. But there are situations when water is carried past the drain pan, which can be an issue […]
