Through the Wall air conditioners are a unitary package system most familiar to us in hotel rooms. They fit through a single cut out in the building with the unit mostly occupying space on the inside. Units exhaust heat and humidity from the room through a louver to the outside. Functionally operates like a window unit the main difference being through the wall units have a dedicated opening cut through the wall.
For industrial HVAC applications, through the wall units are usually one of three different refrigerant configuration types. High temperature refrigeration is anything 32ºF+ up to 60ºF. Low temperature refrigeration being 0ºF to 32ºF and Anything below 0ºF is considered a blast freezer.
Popular with the military and chemical storage companies these systems are often used for cold temperature refrigerations of volatile chemicals. In most cases we manufacturer through the wall air conditioners on a single circuit because units are generally installed in pairs (N+1) for redundancy. Heaters are generally always going to be electric if required.
Flow alarms are available if you’d like, filtration generally isn’t requested but can build it if you want it. Gas detection is generally not pracitical in a through the wall as it’s usually built into the building.
