Standard through the wall air conditioning configuration

Also configurable in Wall Mount, Pad Mount, Roof Mount, or Split configurations, 

using the same components for reduced lifetime costs

Life time cost built to demanding industrial specifications

Innovative two-stage dual refrigeration circuit provides 50% redundancy 

on units over 3 tons

Available corrosion resistant coatings and many other options

CSA certification, UL Listed panels, with ATEX and IECEX certification available.

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

Recommended Options

Corrosion-resistant condenser coating

Air-inlet mounted combustible gas monitor

Building-interior mounted combustible gas monitor

Explosion-proof heating elements (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 recommended in any location north of the 40th 

parallel N or south of the 40th parallel
