**Construction Fastener: Black Countersunk Head Bolt**
A bolt is a type of threaded fastener with an external male thread. Bolts are often confused with screws, but they are typically used in conjunction with a nut. A hex cap screw is a type of cap screw with a hexagonal head, designed to be driven by a wrench or spanner.
An ASME B18.2.1 compliant cap screw has tighter tolerances than a standard hex bolt for the head height and shank length. This means that while a hex cap screw will always fit where a hex bolt is installed, a hex bolt might be slightly too large for a location designed for a cap screw.

Condenser
Baode GPHE condenser is tailored for vacuum condensation. The large vapor inlet connection is placed centrally on the top and the smaller condensate outlet on each side in the bottom. The two medium sized connections for cooling media are centrally placed in the middle, which gives it a symmetrical design.
There are several condensers to be considered when making a selection for installation.They are air-cooled, water-cooled, shell and tube, shell and coil, tube within a tube, and evaporative condensers.
Each type of condenser has its own unique application. Some determining factors include the size and the weight of the unit,weather conditions,location(city or rural),availability of electricity,and availability of water.
Evaporative condensers use water sprays and air flow to condense refrigerant vapors inside the tubes.The condensed refrigerant drains into a tank called a liquid receiver.Refrigerant subcooling can be accomplished by piping the liquid from the receiver back through the water sump where additional cooling reduces the liquid temperature even further.
