High pressure applications are when the operating/design pressures exceed 1,000 psig. The Heliflow Heat Exchanger is a very economical and efficient choice for heat transfer applications as pressures exceed this threshold on either the tube side, shell side, or both. Exceptional Heating & Cooling The Heliflow Heat Exchanger is a compact, helically coiled shell and […]
The following is a comparison of the advantages and disadvantages of both bellows and packed slip type expansion joints. Bellows Type Expansion Joints Advantages Disadvantages • Bellow joints do not require access; i.e. They can be direct buried, however a telltale is recommended • No maintenance is required. • Bellows joints can fail […]
Advanced Thermal Systems (ATS) has long been recognized as the leader in the manufacture of packed slip type expansion joints. Essentially all of the advances in the design of packed expansion joints over the past 40 years were developed by ATS. The following is a comparison between their standard expansion joints and those of their […]
Increasing the amount of condensate recovery will generally have all of the following effects except which one? Reduce fuel consumption. Reduce makeup water consumption. Improve boiler feed water quality. Reduce water treatment chemical consumption. Require exotic piping materials. And the answer is… Reduce fuel consumption. This is an incorrect response. Relatively high‐temperature condensate returned […]
Supercritical fluids require a high pressure and temperature environment; these types of heat transfer applications are well suited to the Heliflow design. The unique spiral tube design of the Heliflow allows it to move freely under thermal cycling as the tube bundle is allowed to expand and contract as necessary. This movement helps alleviate the […]
Everybody loves a bargain, however some bargains come at a high price. Expansion joints are designed with internal and external guides, which are integral with the joint’s stuffing box. The guides require close tolerance for effective guiding of the sliding slip and are critical to leak-free operation, but to be effective these guides must be […]
While there is no such thing as a true “non‐freeze” steam coil (under the right circumstances any steam coil can freeze) there are coils that make it much more difficult to freeze. The proper description of these is “Steam Distributing” due to the tube-in-a-tube and header-in header construction method. These coils all have an inner […]
Flow Design announces it will now be known as IMI Flow Design, shares strategic plan As part of a new IMI Strategic Plan, announced by Chief Executive, Mark Selway, Flow Design will now be known as IMI Flow Design – a brand of IMI Hydronic Engineering (formerly IMI Indoor Climate Group), still based in Dallas, […]
Here is the cost effective method to achieve zone pressure independence in your chilled or hot water system, without the need to install a pressure independent control valve at every heat exchanger or terminal unit. Are you wasting pump energy without knowing it? Are you too hot or too cold? It could be that your control valve […]
