CiSCO Shelters

CEMS Shelters

CiSCO is the only CEMS manufacturer that does it all; from building custom shelters, probes, and CEMS, to creating software packages to meet all your reporting needs. Our CEMS design starts with our shelters, which are completely designed and manufactured by CiSCO. Our designs range from 8’ x 8’ to 10’ x 24’, with different heights and larger widths also available. Shelters must deliver the proper climate and process controls to allow the systems housed within to conduct accurate sample handling, conditioning, and analysis functions necessitated by strict emissions regulations. Safety features include panic exit hardware on the doors, non-conductive, slip-resistant flooring, and smoke detectors.

Custom Shelters

With all our shelters being designed and built in-house, we have the ability to customize the size and layout for your specific site requirements. A single system can be housed in a purpose-built shelter, or multiple systems can put into a single larger shelter. Perhaps you need a place to put a control cabinet or two; they can be placed next to the CEMS equipment rack in a larger shelter. If you would prefer them to be separated, we can construct a shelter with two different rooms and climate control systems. CiSCO has built shelters as small as 6’ x 7’ to house simple CEM systems, to a behemoth 12’ x 26’ shelter to house control system cabinets, to a 11’-6” x 24’ shelter with two separate rooms and an enclosed cylinder storage area with a roll-up garage door.

Hazardous Location Shelters

Sometimes a regular CEMS building isn’t enough. Occasionally a CEMS is needed in an area where a normal shelter can’t go, a Hazardous Location. CiSCO has built and delivered many CEMS shelters for installation in Class I Division 2 locations covering Groups B, C, & D. A Class I Division 2 location is an area where ignitable concentrations of flammable gasses, vapors, or liquids may be present. This would be an area in a facility that under normal circumstances and operations would be non-hazardous, but due to the proximity of flammable gasses, vapors, or liquids has the potential to be in a hazardous environment should a leak or other abnormal conditions occur.

Cylinder Storage

All CEM systems require compressed gas cylinder bottles for the daily calibration checks of the instruments and other quality assurance tests, such as the 40CFR60 Cylinder Gas Audit (CGA) and the 40CFR75 linearity checks. CiSCO builds and designs CEMS shelters with two different types of cylinder rack storage options: our standard hooded exterior cylinder storage and an enclosed garage door style. Both styles are designed so that cylinder gas bottles are easily accessible, protected from the elements, and the QA test procedure is as automated as possible. Each design is capable of housing cylinders up to 12 inches in diameter and has safety chains/straps to securely hold each cylinder in place. Each cylinder position has a designated pressure regulator, hose, and CGA fitting with a built-in check valve for the cylinder. All of the regulators are mounted to the shelter as well, no need to juggle them around when switching a cylinder.

Standard Cylinder Storage

Our steel sided shelters can be equipped with easily accessible cylinder storage areas on the exterior walls of the shelters. These hood-covered cylinder racks are made of 1.5”x1.5” square steel tubing and are securely mounted to one or more of the external building walls. The hood protects the regulators and the tops of the bottles from the sun, wind, rain, and other environmental factors. The racks can either be built large enough to accommodate all the necessary cylinders for daily calibrations and quarterly QA checks or two racks can be used to house all of the cylinders, even if they are on different sides of the shelter.

CEMS without the Shelter

Cabinets

CiSCO can put a CEMS into a fully enclosed NEMA 3R (or 4X stainless steel) cabinet with single or dual access (front only or front and rear). We typically use 6-foot-wide two-bay cabinets that are 6 feet tall with the analyzers in one bay and the sample handling equipment in the second. The cabinet can also have fans for air movement if it is in a climate-controlled environment or an HVAC for climate control if it is located outside or inside a non-climate-controlled building. The electrical equipment can either be in the front for a single access or in the rear for a dual access cabinet. Windows, with UV protection if outdoors, can be added to the front to see analyzer readings and pressure and flow settings without opening the cabinet. It is nothing less than a full CiSCO CEMS with a smaller footprint.

Free-Standing Racks

If you have an existing shelter or other suitable location for a CEMS it can also be supplied in a NEMA 12 open rack. Our open design racks allow easy access to the front for reading pressures, flows, and analyzer values, and to the rear of the rack for maintenance and troubleshooting. Everything can be installed in a 19-inch multi-bay rack for convenience and size; the number of bays varies by the monitoring requirements of your CEMS. If space is an issue, we can provide the combination of a 19-inch rack with one or more wall mounted panels to house the sample handling and electrical systems. This puts the analyzers and some plumbing into a single rack and everything else up against a wall of an existing building minimizing the space needed for a full CEMS.

CiSCO Probes

CiSCO Probe

The model EP750 probe is our standard and most popular probe. It includes: 316 Stainless Steel body and wetted parts. Viton Port seals, Replaceable ceramic filter disk, 316 Stainless Steel Insertion Tube, Supports gas temperatures up to 400 0F, Comes standard in a steel enclosure with the option of stainless steel, Has heated filter chamber with 150-watt 120 VAC rod heater
