Heated Enclosures for Gas Chromatographs

Yes. The ThermaGuard Retrofittable Enclosure uses a patented modular design that can be installed around existing instruments without taking them offline. Individual parts can be replaced, and the enclosure can be installed all at once or in stages. This approach helps reduce installation disruption while improving access to instruments, tubing bundles and related connections.

When equipped with a ThermaGuard Heated Liner, the enclosures can maintain temperatures above 75°F in ambient environments reaching -60°F. Actual performance depends on the selected liner, insulation, heater configuration and site conditions. Terrapin provides heated liner options and technical support to help evaluate suitability for a specific gas chromatograph installation.

The ThermaGuard Retrofittable Enclosure is associated with IP66 protection, while the ThermaGuard Expandable Enclosures provide IP65 protection. These ratings support dust-tight or dust-protected and water-resistant enclosure performance as specified for each product. The appropriate rating should be selected according to the instrument environment, installation arrangement and project requirements.

Yes. ThermaGuard Expandable Enclosures are designed for single, double or triple instrument configurations. Their expandable design provides flexibility for installations with multiple gas chromatographs or related process instruments. Replaceable back plates can be field-punched for power wiring, control wiring and process tubes, allowing entry-port configuration to align with the installation.

ThermaGuard systems include options for hazardous-location applications. Class 1 Division 2 rated thermo-electric coolers are available for the expandable enclosure system, and the heated liner can be used in T6 areas according to the provided product information. Project teams should confirm the complete selected configuration and site classification before specifying the enclosure.

Terrapin Industrial provides technical support and installation service for these enclosure systems. Support may include field installation assistance for process tubing, electrical connections, block heaters, calibration and testing, as well as entry-port configuration for expandable enclosures. Replacement parts are available for individual components, supporting staged installation and ongoing maintenance.
