Features and Benefits Overview                                                                                                                                                                                                            

Units from two tons (24,000 BTUH) to 50 tons (600,000 BTUH) utilize dual spark-proof 

evaporator blower assemblies

Multi-stage refrigeration circuits on most units allows for 50% redundant 

backup cooling*

High and low refrigerant pressure on all circuits

Compressor high current/temp overload

High temperature in the heating coil

Basic features of standard InPac® HVAC control panels include two-stage 

control on both heating 

and cooling, automatic switching, and manual override switches for individual stages

Standard coils are constructed from heavy-weight rifled copper tubes mechanically 

bonded to aluminum fins

InPac® evaporator and condenser coils interlace completely separate refrigeration circuits

Condenser coils are designed at 8 FPI to reduce clogging in industrial environments

Evaporator coils are designed at 11-13 FPI for efficiency

Freezestats are standard on all InPac® systems

Crankcase heaters are standard on all InPac® systems

Corrosion-resistant condenser coating

Copper finned/Copper tube coils

Clogged/Dirty filter monitoring via magnahelic or photohelic gauges

Finned-tube heating elements in dusty environments (often required in some applications)

Chemical air filtration to reduce corrosive particles

Corrosion resistant coil coating on all coils such as our SpecificCoat 2-stage coating

Low ambient controls to allow for mechanical cooling in lower temperatures

Additional cabinet coatings to protect against specific corrosive chemicals
