Customized Environmental Rooms

Norlake Scientific Enviro-Line rooms are constructed of polyurethane insulated panels. Polyurethane offers superior temperature-retaining properties, which also boosts energy efficiency. With a 97% closed cell content, polyurethane also provides excellent moisture resistance. Because polyurethane foam allows for thinner walls, you also get the maximum interior storage space. Norlake Scientific foam is also environmentally friendly since it has a blowing agent with zero ozone depletion potential.

Installation is simple whether you choose a multi-temperature or constant-temperature room for indoor or outdoor application. Norlake Scientific’s modular panels with cam-lock construction make it easy to assemble your structure. Locks are easily activated using a factory-supplied 5/16-inch hex wrench. Should you need to relocate or add panels, you can remove your controlled environmental room and reassemble it.

Panels used in Norlake walk-in environmental chambers feature a tongue and groove design for proper alignment and a dependable seal. To further ensure a tight seal, there are continuous gaskets around the outer perimeter of the panel without cuts or breaks at corners. Gaskets are foamed-in-place to prevent falling off or pulling off during shipment or installation.

Standard four-inch thick panels are made to hold up to daily usage with 26 gauge corrosion-resistant coated steel interior and exterior. Customized rooms supplied with a floor will include a smooth aluminum interior surface. Other wall and floor finishes and a five-inch thickness are available to suit your application.

Standard doors maintain inside conditions by creating an airtight seal. Doors feature a stepped profile design which forms a barrier to airflow. Other door components like spring-loaded hinges, spring-activated door closers and magnetic gaskets also help create a dependable seal.

Standard door widths are 26″, 30″ and 36″, but other widths and door types are also available.

Industrial quality refrigeration systems supplied with Enviro-Line rooms may be air- or water-cooled. Either way, you can depend on your system to consistently provide the necessary cooling.

Each refrigeration system features high-quality components for added dependability and efficiency. Energy-efficient compressors and motors, for example, provide maximum energy savings, while eco-friendly refrigerants help protect the environment.

Norlake can also supply a redundant refrigeration system to protect against system failure due to weather or other conditions for added security and peace of mind.

Electronic control panels provided with Enviro-Line rooms are fully programmable for the most precise control over operating parameters, including air temperature, humidity and lighting. These controllers can also integrate into existing building systems for more straightforward operation. Optional chart recorders keep a record of temperature and humidity performance.

Control panel selection offers a variety of control needs, including temperature monitoring of air and product temperatures, monitoring ˚C or ˚F, temperature adjustment, temperature documentation on chart recorders and audible and visual alarms. Advanced control provides a +/- 0.15˚C and +/- 1.0% accuracy.

Other control panel features include:

• Emergency shutdown switch
• Quickly adjustable air and product Hi/Lo temperature and alarm settings
• Key lock door for security
• Touch pad programming
• Easy-to-read alphanumeric displays
• Dry contacts for remote alarm
• Power failure alarm

Custom-designed control panels are available for unique applications.

Electronic control systems are valuable options for controlled environmental rooms. These systems make tracking room performance and adjusting settings simple. The LogiTemp® Plus With Reverse Cycle Defrost electronic control system features an easy-to-use tablet interface on the front of the control panel. Operators may monitor and adjust refrigeration settings on site or remove the tablet and take with them for remote access. If there’s a problem, LogiTemp Plus warns immediately via error codes and online data.

LogiTemp Plus also boosts system efficiency and provides many other benefits:

• More precise and reliable controls than an all-mechanical system for increased product safety
• LogiTemp Plus patented design saves up to 27% more energy than an all-mechanical system
• Demand Defrost technology initiates a defrost only when needed for further energy savings
• Access system performance data from any other device with an internet connection, including PC or Mac desktops and Android or iOS smartphones.
• No need for a service tech to climb onto a roof or enter the freezer to monitor or adjust the refrigeration system

Other options for customized environmental rooms include an ultrasonic humidifier that provides up to 8 pounds of water per hour. Also, disinfection systems using specially designed ultraviolet radiation lamps are highly effective in killing bacteria, viruses, mold and yeast.

Other customizations include:

• Diamond tread flooring
• Exterior door ramp
• Shelving kits
• Viewport door (standard size is 14″ x 14″)
• Duplex electrical outlets
• Heater kit for cooler located outdoors in below 0˚C ambient
• Leak detector/alarm (may be a requirement in some areas)
