The cooling water distribution system distributes evaporative cooling water onto the heat exchanger device to wet only a portion of the heat exchanger device while allowing a remaining portion of the heat exchanger device to be dry. The air flow mechanism causes ambient air to flow across the heat exchanger device to generate hot humid air from the ambient air flowing across the wet portion of the heat exchanger device and hot dry air from the ambient air flowing across the remaining dry portion of the heat exchanger device. Methods are also described. | 03-22-2012 |

The hot fluid to be cooled is distributed from the cooling fluid distribution system onto the direct heat exchanger device. In a hybrid wet/dry mode, ambient air flows across both the indirect heat exchanger device and the direct heat exchanger device to generate hot humid air from the ambient air flowing across the direct heat exchanger device and hot dry air from the ambient air flowing across the indirect heat exchanger device. | 03-15-2012 |

The tubes have a center-to-center spacing generally horizontally and normal to the longitudinal axis of the tubes of substantially 109% to substantially 125% of the nominal tube outside diameter, and a generally vertical center-to-center spacing of substantially 100% to about 131% of the nominal tube outside diameter. | 01-19-2012 |
| 20110100593 | HYBRID HEAT EXCHANGE APPARATUS - A hybrid heat exchange apparatus for indirectly transferring heat between a process fluid and ambient air includes an evaporative heat transfer cell operative in a wet mode or a dry mode, a dry heat transfer cell and a fan. The air may bypass the dry heat transfer cell to flow through a first air passage or may flow through a second air passage through the dry heat transfer cell and in either event, then through the evaporative heat transfer cell. The air may partially flow through and partially bypass the dry heat transfer cell, and then through the evaporative heat transfer cell. The evaporative heat transfer cell optionally may include a direct contact evaporative heat exchanger. Manually or automatically controlling air flow based on ambient conditions provides efficient and economical control of the hybrid heat exchange apparatus, while avoiding problems in freezing conditions. | 05-05-2011 |
| 20100163127 | SAMPLING APPARATUS - A sampling apparatus for sampling a fluid from a fluid source includes a first fluid passage device, a second fluid passage device and a fluid by-pass. The first fluid passage device is disposed downstream of and in fluid communication with the fluid source. The second fluid passage device is disposed downstream of and is in fluid communication with the first fluid passage device. The fluid by-pass is disposed downstream of the fluid source and upstream of the second fluid passage device. The fluid by-pass being in fluid communication with and disposed between the fluid source and the second fluid passage device is operative to cause a first portion of the fluid to flow through the first fluid passage device and to cause a second portion of the fluid to by-pass the first fluid passage device and to flow to the second fluid passage device. | 07-01-2010 |
