DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanism followed the bit down into the hole. Applications were later found for the DTH method underground, where the direction of drilling is generally upwards instead of downwards. [pdf]
Dry screw vacuum pumps require no water or oil for sealing or lubrication in the vacuum stages. Consequently, these dry vacuum systems eliminate effluent generation, pollution,. .
VSB dry screw models operate at any pressure between blank of and atmospheric pressure. Pumping capacities are virtually limitless when paired with a high vacuum booster pump. .
The VSB Series low rotational speed ensures smooth and robust operation. Engineered to offer higher discharge pressure handling capabilities than vertical designs, allowing for more process time. With higher vapor and liquid tolerances, dry screw vacuum. [pdf]
Recover up to 80% of your oil-injected screw compressor’s waste heat as hot water and re-use it somewhere else as hot water or steam. The compression process generates a lot of heat in the drivetrain. [pdf]
Your compressed air system represents an excellent source for heat recovery and could improve the efficiency of the system overall. Improving the performance of your compressed-air system reduces your plant wide energy costs. It can reduce downtime, increase your production throughput, lower your scrap. .
Compressors Air-cooled, packaged, rotary screw compressors are very amenable to heat recovery for space heating or other hot air uses. Ambient atmospheric. .
Heat recovery for space heating is not as common with water-cooled compressors because an extra stage of heat exchange is required and the temperature of the. .
Oil-free rotary screw compressors offer a much better opportunity for heat recovery. As typical with all compressors, the input electrical energy is converted. .
Engine-driven compressors have the same kind and volumes of low-grade heat available off the air end, but there is also a higher temperature option off the engine.. [pdf]
