Where critical levels of temperature and humidity must be maintained, HEMCO officials said its pre-engineered modular enclosures offer a cost-effective alternative to conventional construction. They also aim to provide the quality, durability and performance that Coordinate Measuring Machines (CMM) demand. CMM rooms are specifically designed to maintain a +/- one degree temperature consistently. The modular room provides the environmental precision and accuracy necessary for companies that need to meet tight specification standards. Wall and ceiling panels are chemical resistant, smooth, and non-porous for easier cleaning and decontamination. In addition, special oil mist or HEPA filtration can be designed into the CMM room providing high levels of cleanliness.
