SED North America This aseptic Purified Steam Sampling Unit (photo) can be permanently installed at the point of sampling, or is portable for sampling throughout the purified-steam distribution. The unit consists of an internal cooling water circuit allowing an operator…

A new, larger version of this compact heat exchanger

The newest and largest member of the Compabloc family of heat exchangers, the Compabloc 120 (photo), will be on display for the first time at this firm’s stand. The Compabloc 120 offers a big boost to any natural gas, petroleum,…

These stainless-steel boilers are ideal for clean steam applications

These stainless-steel electric steam boilers are suitable for ultra-pure applications, including: autoclaves, cosmetics, medical research, pharmaceutical, pure humidifier and sterilization. Electric stainless-steel boilers are ideal for clean steam in that they can be located near the process, thereby reducing contamination…

An enhanced steam-water washdown system

The STVM Dual Mix washdown stations provide instantaneous hot water economically and safely by blending steam and cold water to the required set temperature. The system is designed for general cleaning applications where hot water is required, such as for…

Heat Transfer Fluid Leaks: Break the Fire Triangle

Management of process plants requires the understanding and application of the fundamental tenets of safe design, construction, and operation of each facility. In that context, many years of practical experience with systems that use very high-temperature organic heat-transfer media has…
