Process Vacuum Systems

Wintek has over 30 years of experience designing custom process vacuum systems for a wide variety applications and industries and is a capable of utilizing many different vacuum technologies to supply the most reliable and cost effective design for the application. Our equipment is commonly used on many different types of process equipment including: Vacuum dryers, batch reactors, filter dryers, extruders, distillation columns, evaporators, and many more. Wintek has designed systems operating continuously as low as 30 microns.


Wintek leverages its extensive background in vacuum technology to design custom systems to specifically meet the customer’s needs. Wintek regularly designs and supplies systems utilizing a wide variety of equipment: Solvent recovery liquid ring packages, vacuum boosters, air ejectors, hybrid steam jet condensers, dry pumps, rotary vane and rotary pistons. We are not locked into a specific technology and will always select the type of system we feel is best suited for the application in terms of cost and reliability.

Wintek’s solvent recovery vacuum systems are used in many industries including chemical, pharmaceutical, metal powders, flavor and fragrance, and PET solid state. We have designed systems to recover such solvents as alcohols (ethanol, methanol, IPA), toluene, xylene, acetonitrile, mineral spirits, limonene, decane, and others. In many cases we are also sealing a liquid ring pump with one of these high vapor pressure solvents to maximize recovery and reduce potential contamination or environmental concerns. This requires an extensive knowledge of how equipment such as boosters are affected when sealing a pump with a potentially high vapor pressure solvent, even when operating at deep vacuum.
