Exterior Wall Mount HVAC

Easy installation and minimal wall cut outs save time and reduce cost

Specific Systems® wall mounted air conditioning units are quick to install and practical for applications where portability is a concern. Wall mounted units give a single point of connection and dismiss requirements for additional concrete pads.

The standard vertical through the wall mounted InPac units are designed to provide maximum capacity in the smallest possible footprint. By engineering the cabinet to fit to- or through-the-wall, mounting stability is combined with ease of access, allowing most components of the unit to be serviceable from within the conditioned space.

Regardless of configuration, our units are built to serve in nearly any industry or application, including

Refineries
Water/Wastewater Treatment Plants
Oil drilling rigs
Offshore processing plants

Commercial/Light Industrial or Severe Duty Designs

To-the-wall configuration reduces interior and exterior space requirements

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.

Ranging from 2 to 50 tons, the systems we manufacture are designed to provide safe and effective environmental control under the most difficult conditions. For nearly 50 years. Specific Systems® has been manufacturing ECUs that perform reliably in the most challenging industrial applications, including hazardous, explosive areas.

To-the-Wall? or Through-the-Wall?

Your application's available wall space, access to the building interior, and maintenance access may limit the cabinet configurations you can apply. Further, some buildings aren't constructed to support large roof mounted systems, and split system designs may be inconvenient in your location.

Our to-the-wall mounted design requires only two small cutouts to be made in the building shell, each corresponding to the supply and return air locations. The entire AirPak and AirPak-E product lines utilize this design philosophy. InPac® severe duty and explosion proof units can also be configured as to-the-wall.

Through-the-wall designs can be thought of like a large window-style HVAC system, wherein a single, larger opening is created in the building to allow the entire front of the unit to slide in. This configuration style gives access to the control panel, along with allowing a single point of connection inside the building, and providing maintenance access to the systems.

Maintenance Accessibility

The through-the-wall design used on our standard inPac series of units allows for much easier maintenance than competiting units. Since the entire front of the HVAC system is inside the conditioned space, most of the unit's components can also be accessed from inside the building, just by removing a panel.

Allowing access in this manner minimizes the need for scaffolding and other time and expenses in order to perform routine maintenance. In fact, even some of the more intensive tasks such as motor or compressor replacement can be performed from inside.

When systems are mounted on buildings that are on piers or otherwise elevated, such as those in dusty mining environments, this feature of the InPac® systems because an even greater time-saver.

Portability

Mounting HVAC units to the wall of the building helps in many ways, including minimizing transportation costs. This is especially true for mobile buildings, or even in applications with restricted access.

Our 2-20 ton HVAC systems designed in a wall-mounted configuration can often be mounted and fully installed prior to shipping. These units can also be tested during the integration and building FAT, then remain installed to ensure the entire building is ready to go upon delivery to the end user.

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 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® and AirPak systems
Crankcase heaters are standard on all InPac® amd AirPak systems

*Explosion proof modulating damper motors used only in situations where where required by statute, regulation, certification, or specification
** Multi-stage cooling is comprised of dual circuits on units with capacities 3-tons through 30-tons, with quad circuits on units 35-tons and larger
