With top rated C1D1 & CO2 safety features and unparalleled design, it’s no wonder the EXLab design is the best-selling extraction lab on the market today! These units were built with compliance in mind, leaving nothing overlooked. Each extraction lab is manufactured in the United States from domestic equipment and complies with the strict industry regulations and requirements of IBC, NEC, OSHA and NFPA.

The safety features of the EXLab include one-hour fire rated walls, meaning your extraction lab can be placed indoors or outdoors with no additional exterior structure required. A responsive ventilation system is controlled by an automated system that monitors hazardous gases, keeping the levels well below regulated maximums. Moreover, EXLabs require little disassembly before moving, allowing you to be compliant in new locations as you move or scale.

Which EXLab Is Right For You?

Each of our EXLabs can be setup to accommodate multiple workstations and technicians. However, your preferred extraction method will determine which model you will need. All four models come in four sizes to fit your space and operation.

Norseman’s C1D1 and CO2 extraction labs are not only the safest portable units available today, but have also withstood the test of time for compliance and regulations.

Furthermore, EXLabs are delivered fully assembled and ready to go. There is very little work to be done to connect it to your infrastructure.

The EXLab Design Concept

A EXLab can be designed as a CO² or C1D1 (Class 1 Division 1) Extraction Lab. It can provide an environment suitable for the constant presence of flammable gasses or CO². All of the equipment you install inside the C1D1 room should also be rated for use in a C1D1 environment.


The enclosure consists of 1-hour rated, GMP compliant walls and ceilings, per code requirements. One common misconception is that the unit be rated “explosion proof” or “blast rated”, but this is not necessary. The ventilation and electrical systems have been designed to eliminate the possibility of an explosion.


The ventilation system can be designed to create a linear flow of air through the room to quickly evacuate any flammable gasses that might accidentally be released in the room. Code requires the gas concentration remain below 25% of the LEL (Lower Explosive Limit). The LEL is the minimum gas concentration to allow conflagration, so 25% is only 1/4 of what is required for ignition. We’ve held ourselves to a higher standard and have our LEL set point at 10% for ventilation.

There are two stages to our ventilation system: primary and secondary. The primary system includes the HVAC unit and a primary fan. It will remain on any time the lights are turned on, as required to maintain the temperature setting on the thermostat, and when signaled by the gas detector. The secondary system includes a motorized damper and a secondary fan that will engage starting at 10% LEL. It’s designed to quickly evacuate and replace the air to ensure the gas levels remain below the code required amounts. All exhaust air evacuates directly outdoors and all intake air comes from an outdoor location.

The ventilation system can also be designed to create a comfortable & safe work area by providing enough fresh air circulation to cycle-out any CO² that might accidentally be released inside the room, while maintaining room temperature.

Gas Detection

A gas detector can be installed that will control the ventilation and notify occupants of the room in the event of a gas release inside the room. Once gas levels reach 10% LEL the secondary ventilation system will engage and a visual indicator on the gas detector will be illuminated, so action can be taken to remedy the situation. If the gas levels continue to rise to 20% LEL an alarm will sound and the receptacles powering the extraction equipment will be powered down. Once the gas has been cleared the alarms will cease and the secondary ventilation will power down. If, for some reason, the gas detector stops functioning the receptacles and lights will be powered down and emergency lighting will engage to facilitate egress from the module, but ventilation will continue uninterrupted. After a fault condition the breaker controlling the receptacles must be manually flipped to restore power.

A fixed gas detector can be installed that will monitor the CO² levels and notify occupants in the event of a gas release. The safe CO² levels, as defined by OSHA, should be held below 5000ppm. Norseman has held ourselves to a higher standard and have our ppm set points at 2000 & 4000ppm. Once gas levels reach 2000ppm a visual indicator on the gas detector will be illuminated and a strobe will begin to flash inside the unit, so action can be taken to remedy the situation. If the gas levels continue to rise to 4000ppm an alarm will sound and the receptacles powering the extraction equipment will be powered down. Once the gas has been cleared the strobe and alarm will cease.


All of the electrical equipment installed inside the C1D1 area will be rated for C1D1 use and UL listed; including, but not limited to: the lights, receptacles, switches, and gas detector. This means that they are sealed and/or intrinsically safe. Even in the event that the room atmosphere reaches 100% LEL or above, there is no chance of an ignition from the electrical components.

There is a single enclosure with a disconnect switch on the exterior of the module where the main power is connected, this is the main “kill switch”. All wiring inside the module will be completed up to this enclosure, but any remotely located devices will need to be wired separately.

Fire Suppression

If you’ve opted to have our fire suppression system supplied, one or more dry chemical suppressant units will need to be installed on the module ceiling. These units are individually heat initiated and come ready for use from the manufacturer. The pressurized bottles are considered a hazardous load and will be shipped directly to your site for field installation to the factory installed mounting hardware in the EXLab. This is a very simple install, just screw the bottle onto the provided mounting base, just like a light bulb.

Additional Systems

The module’s PLC has the ability to signal other devices such as flow valves for your solvent system and alarm panels, but Norseman does not currently cover these items in our scope. If you will be connecting to any ancillary systems please let Norseman know, so we can help facilitate a seamless integration and provide you with the appropriate support.
