Environmental Room Cooling Systems
Precise Control of Temperature, Relative Humidity, and Air Flow

Quality Engineered Structures Environmental Room Cooling Systems Image2 Environmental room cooling or refrigeration systems provide the environmental conditions required by the process to be performed within the enclosure. Several types of systems and designs from skid mounted package units, spilt systems, and desiccant systems can be installed depending on environmental room specifications. Precise control of temperature, relative humidity, and air flow can be accomplished to temperature ranges of -73°C to 85°C and humidity ranges of 20% to 95%. Dry rooms can be controlled to 2% relative humidity with unitary desiccant dryer packages. Air flow control in environmental rooms can be vertical, horizontal, laminar, or unidirectional to create the gradient control required by the process or storage system. Depending on budgetary constants and intended process specifications can be written to meet or exceed any requirement.
