AIREX PRO-SYSTEM KIT™ (AIREX TITAN OUTLET™ & AIREX E-FLEX GUARD™) a combined 2-in1 protection system by Airex Manufacturing Inc., to be provided and installed for sealing wall penetrations of HVAC refrigerant line and protecting the refrigerant line set piping insulation. The use of a combined sustainable compression gasket and seal system is the preferred method in the requirements per energy codes, to seal refrigerant line wall penetrations, therefore to prevent wall air-leakage, moisture intrusion, weather intrusion, rodent intrusion, vibration control, physical wall damage, when connecting with refrigerant piping or thermal insulated refrigerant piping. The wall seal outlet must feature an elastomeric sleeve and stainless-steel clamp ensuring a mechanical connection to the pipe insulation protective cover. The connecting refrigerant lines exposed to weather must all be thermal insulated. All pipe insulation material (whether it is exterior surface coated or non-coated) must also be completely covered and protected from sunlight, moisture, equipment maintenance, wind, snow, ice, rodent damage, physical damage, and shall provide shielding from solar radiation that can cause degradation of the material. AIREX PRO-SYSTEM KIT™ to be provided is to ensure healthy building indoor air quality, long-term building durability, sustainable building energy efficiency, and optimal HVAC Equipment System Performance.
