Customer Challenge

The company’s 400,000 sq. ft. warehouse required several alterations before being utilized as a medical manufacturing facility. Maintaining stable humidity levels is essential when designing a cleanroom, so the company needed to upgrade the warehouse’s dehumidifiers to maintain tight humidity control, creating a safe and sterile location for manufacturing.

Stark Tech Solution

The Stark Tech Equipment team worked with IPD engineering to install Polygon rental dehumidifiers to maintain the space while permanent Munters Dehumidification Systems were installed and brought online. These systems are designed to remove moisture from the air to control humidity in commercial spaces and industrial buildings.

Cleanroom HVAC engineering is a challenging concept. It takes a mixture of engineering skills, experience, and a solid understanding of the particle-generating potential of the process. Our experienced team customizes solutions combining quality engineering, reputable manufacturer products, and certified equipment to meet cleanroom standards.


The manufacturing facility was built and up and running in just 15 weeks. Tessy Plastics hired 200 additional employees, including chemists, operators, technicians, and more.  The dehumidifiers that Stark Tech installed maintained even tighter humidity control than initially designed and are still in commission today.
