Heat Transfer Performance of Propylene Glycol Versus .

tests described above were repeated at a cooling air flow rate of 6.10 m/s (1200 sfpm). The results are shown in Figure 8 and Table 3. Again, the heat transfer perfor-mance of this downflow radiator was considerably less when using the Propylene Glycol solution than when using the Ethylene Glycol solution at coolant flows below 5.05 L/s (80 gpm).

Do you need a low temperature cooling water circulation .

The water in the cooling "water" circulation pump is the circulating medium in the circulation pump and is not limited to the "water" medium. The test temperature is limited to normal temperature ~ 0 ° C; if lower environment 0 ° C ~ -115 ° C is required to use ethylene glycol or its solution as a low temperature circulating pump cooling medium.

GLYCOL CHILLERS & PARTS - Installation Parts Supply

A glycol chiller is a refrigeration system that is used to cool a bath or a tub of antifreeze named "propylene glycol", or just "glycol". The cooled Glycol is recirculated by pumping though a looped circuit of tubing connected to the input and output ports of a glycol chiller. This is the main cooling line.

Ethylene Glycol and Propylene Glycol Toxicity: What .

Oct 03, 2007 · An inherited metabolic disorder can present as ethylene glycol intoxication from laboratory results (Pien, van Vlem et al. 2002). Glycolic Acid Analysis Recent studies have demonstrated usefulness of glycolic acid analysis in ethylene glycol poisoning cases (Fraser 1998; Porter, Rutter et al. 2001; Fraser 2002).

What Is Glycol? How is it Used in a Chiller? | JCY Younger .

For instance, a solution of 10% ethylene glycol freezes at -3.4 C (25.9 F), 30% ethylene glycol freezes at -13.7 C (7.3 F) and 60% ethylene glycol freezes at -52.8 C (-63 F). The freezing point of a 60/40 ethylene glycol/water mixture is much lower than that of either pure ethylene glycol or pure water.

Established in 1979, CHEM Group-Troy, formerly Consolidated Recycling Co., Inc., specializes in the reclamation of glycols from spent automotive antifreeze. Also processed at this site are various industrial glycol streams, biodiesel based crude glycerin, and high aromatic content crude oils.

Quick Connect Shut-Off Couplings - Liquid Cooling Solutions

Koolance patent-pending quick disconnects (QDC) are specially designed fittings which automatically shut-off coolant flow upon disconnection. The flow path is reestablished when the couplings are connected. Quick disconnects are very useful for areas in a water cooling or plumbing system which are altered and moved frequently.

Water Cooling for Induction Systems: Inside and Out

(which consists of cooling tubes, fins, and fans). These air-cooled systems are very low maintenance compared with evaporative systems, but they lack the cooling capabilities of evaporative towers. Pressurized closed-loop cooling towers require the use of glycol to pre-vent freeze damage in the pressurized bundle, and they have a collection pan

Glycol Dehydration Process - an overview | ScienceDirect .

The glycol dehydration process is an example of a process that provides absorption dehydration, and in the process, a liquid desiccant provides the means to absorb water from the gas stream. Ethylene glycol (HOCH 2 CH 2 OH) was, initially, the principal chemical agent in this process, has a very strong affinity for water and when the glycol is in contact with a stream of water-wet natural gas .
