ONSHORE/OFFSHORE - Explosion proof packaged air conditioners can be designed for either roof mounting or installation at grade and can be provided with complete ductwork systems. Larger packaged units can be designed to cool, heat, and provide Type X, Y, or Z pressurization.   Gas-phase air filtration can be incorporated into these systems to remove hydrocarbons and acid gases. 

All units may also be marked with the US and Canadian Class I, Zone system upon request (example: Class I, Zone 2, group IIB+H2).

Typical applications include control rooms, switchgear buildings, motor control rooms, RIE buildings, driller’s cabins, and many others for both onshore and offshore service.

CSA (C/US) Certified from 1-1/2 to 20 tons for Class I, Division 2, Groups B, C, D hazardous (Classified) locations, packaged air conditioners and heat pumps can be furnished with auxiliary blowers, motorized dampers, electric heat (in air conditioners), thermostatic controls, control panels for pressurization and/or timed lead-lag for redundant air conditioners, and many other features to satisfy customer needs in heating, cooling, humidity control, pressurization, etc.  Options include the Marc protective coating or stainless steel cabinet and coil coating for corrosion prevention.

IEC Zone 2 - The PACF series is similar to the PACX except that it is designed for use in IEC Zone 2 hazardous areas.  Although they do not bear the CE mark or A.T.E.X. certification as required for installation in the European Union, they are intended for use in other countries that prefer the IEC methods of protection.   The PACF series air conditioners are certified to conform to Zone 2 requirements by Marc Climatic Controls and all applicable Certificates of Conformity will be provided for components.   These air conditioners are not for installation in North America.

Custom units can be designed and manufactured to comply with special customer requirements.  Packaged units can be designed and furnished to provide dual air conditioning and ventilation systems in a single cabinet.  The DPAX series shown at the right was designed for use with analyzer shelters to provide 100 percent redundant air conditioning and heating with gas-phase air filtration for the make-up air, dehumidification, humidifiers, and dual ventilation blowers.   Two explosion proof disconnects were installed on each cabinet.  With dual built-in control sections, each unit was provided with a separate thermostatic control panel for mounting inside the shelter.  Each unit was CSA certified for Class I, Division 2, Groups B,C,D hazardous (classified) locations.
